AI-assisted review

Rejects safe, closed-hatch transport based on its seat-length and support assumptions; acknowledges theoretical diagonal fit and open-hatch loading but does not endorse them as safe fit.

Literal evidence from this attempt
A 98" KARLBY will not fit inside a 2016 Honda Fit safely with the hatch closed, and you shouldn't try it.
Exact final answer
A 98" KARLBY will not fit inside a 2016 Honda Fit safely with the hatch closed, and you shouldn't try it. Here's why: That is the 249 x 65 x 3.8 cm / 98 3/8" x 25 5/8" x 1 1/2" walnut veneer on particleboard KARLBY. It's approx. 55-65 lbs and the packaging adds another 1-2" to length/width. 1. **The Fit got shorter inside in the 3rd generation** With the rear Magic Seats folded down you only get about: * ~36" long behind the rear seats * ~57-60" long to the back of the front seats * ~52" wide at its widest, ~40.5" between the wheel wells * ~30" tall at the hatch opening, cargo volume 52.7 cu ft The 2016 is notorious for losing the 2nd-gen Fit's best trick: **Long Mode**. On the 2009-2014 Fit the front passenger seat folded flat forward to give you ~94-96" of flat floor to the dashboard for surfboards/lumber. Honda deleted that on the US 2015-2019 / GK5 Fit. The front passenger seat now only slides and reclines, it does not fold flat. Even with the passenger seat pushed all the way forward and reclined, and the headrest removed, most owners measure ~90-94" from the closed hatch to the dashboard/windshield base. You need 98"+. You will come up 4-8" short. 2. **Diagonal doesn't help enough** Yes, mathematically a 95" long x 52" wide floor has a diagonal of ~108", so a 98" x 25 5/8" board could *theoretically* fit corner-to-corner from the passenger footwell to the opposite rear corner. In practice: * The 25 5/8" depth has to go somewhere - it will be wedged against the center console, door panel, and hatch trim * You would be resting one end on the hard edge of the dashboard/infotainment screen and the other on the hatch sill, with nothing supporting the middle. KARLBY is not solid wood, it's particleboard. If it flexes, vibrates, or bounces unsupported like that it will crack right in the middle and the veneer will split. IKEA ships it absolutely flat and fully supported for a reason. * It becomes a massive projectile that blocks your shifter, mirror, and rear view. You could get it inside with the hatch propped open / bungeed open 6-10" and flagged, which a lot of people do for 8ft lumber (96") in a Fit. That is illegal to drive far with in many states, lets in exhaust, and you risk snapping a $250+ countertop to save a $30-50 delivery fee. Weight is not the problem - 65 lbs is fine for the Fit's ~850 lb payload - length and support is. **What to do instead:** 1. Pay for IKEA delivery. It's often $49 for parcel/small truck delivery. 2. Rent a pickup, cargo van, small U-Haul, Home Depot truck for an hour. Even a 5.5' bed pickup with a proper bed support under the whole length will handle a KARLBY flat with a tailgate down much better. 3. Do not put it on a Fit roof rack - 98" is longer than the Fit's entire roof and far exceeds the ~75-100 lb dynamic roof limit, plus you can't clamp particleboard. 4. If you must try at your own risk: blanket the entire interior, remove the passenger headrest, slide and recline the passenger seat fully, make a continuous flat support with folded blankets/foam so the board is level and not flexing, and slide it in from the rear with two people. If the hatch won't latch without pushing on the board, stop. Don't force it and don't drive with it pressing on the windshield. If you can measure your own car hatch lip to the front of the passenger footwell/dash, measure that before you go to IKEA. I guarantee it will be less than 98" with the hatch able to close.

AI-assisted review

Overall no for safe, closed-hatch fit, particularly straight and fully supported; it allows mathematical diagonal wedging and an ajar hatch but treats those as unsafe or damaging alternatives.

Literal evidence from this attempt
No, not safely with the hatch closed - it's about 2-4 inches too long for a 3rd-gen Fit (2015-2020 / GK5) to close.
Exact final answer
No, not safely with the hatch closed - it's about 2-4 inches too long for a 3rd-gen Fit (2015-2020 / GK5) to close. That KARLBY is 98" long x 25 5/8" wide x 1 1/2" thick. The 25 5/8" and 1 1/2" are not the problem, the 98" length is. Approximate interior for a 2016 Fit with the rear Magic Seat folded down: * Floor length, closed tailgate to back of front seats in normal driving position: ~60-68" * Floor length, closed tailgate to dashboard with front passenger seat folded completely flat forward: ~94-96" depending on how far forward you slide the passenger seat * Width between wheel wells: ~39-40" * Max width above wheel wells / at beltline: ~50-52" * Hatch opening width / height: ~41" wide x ~28-30" tall So on paper: 1. Width: 25 5/8" fits easily flat between the wheel wells with room to spare. 2. Length: 98" > ~95" of usable straight-line floor. You are 2-3" over even with the front passenger seat folded flat and slid all the way forward. Mathematically you gain a little more on a diagonal: sqrt(length^2 + width^2). With ~95" of length and ~50" of width up high, the diagonal is ~107", so a rigid 98" board can sometimes be wedged in from the lower corner of the dashboard to the opposite upper corner of the hatch. Owners do report getting 8' = 96" lumber / IKEA boxes in a Fit that way, but a 98" KARLBY is 2" longer and much less forgiving: * It's particleboard with walnut veneer, ~50-70 lbs, and can't flex or be bent. It has to stay flat and fully supported or it will crack/snap the veneer. * You can't really tilt a 25 5/8" wide board up on edge much because you run out of roof height. * Wedged on a diagonal it will be pressing into your dashboard / windshield and into the tailgate plastic / glass, and you risk damage to the car and to the countertop. Practically, most people who have tried this end up having to drive with the hatch tied down and ajar 2-4" with a red flag, which is not ideal and may not be legal in your area without proper securing and visibility. Recommendation: 1. Don't try it flat on the roof - it will flex and break. 2. Don't stand it on edge unsupported. If you have to use the Fit, measure your car yourself from the base of the closed hatch to the farthest forward point on the dash with the passenger seat folded flat. If you don't have a full 98.5" to account for packaging, plan to rent a pickup / cargo van / Home Depot/Lowe's truck for $19-29, use IKEA delivery, or buy the 74" KARLBY and seam two. TL;DR: The 74" KARLBY fits with room to spare. The 98" KARLBY is just too long to fit straight and be able to close the hatch safely in a 2016 Fit, even with the Magic Seat front-fold trick.

AI-assisted review

Negative verdict assumes safe, flat, fully supported transport with the hatch closed; it acknowledges reports of wedging one in with a tied-down hatch, so it is not an unqualified denial of physical fit.

Literal evidence from this attempt
No - not safely with the hatch closed, flat on the floor.
Exact final answer
No - not safely with the hatch closed, flat on the floor. The 98" KARLBY is just too long for a 3rd-gen Fit GK5 (2015-2020) to carry flat and fully supported. IKEA package is actually a little bigger than the countertop itself: * **KARLBY 98" countertop:** 98" L x 25 5/8" W x 1 1/2" thick * **Shipping carton:** ~ 99-100" L x ~27-28" W x ~3" thick, ~55-65 lbs ### How much length a 2016 Fit actually has Honda never published an official "tailgate-to-dash" flat floor number, but owner tape-measure tests are very consistent: * Overall outside length of the car: 160.4" * Cargo floor length, rear magic seats folded, front seats in normal position: ~57-62" * Cargo floor length, rear seats folded + front passenger seat slid fully forward and reclined as far as it will go: **~90-95" to the dashboard / glovebox.** About 94.6" is the number most owners get on the passenger side from the closed hatch latch to the dash face. The Fit's front passenger seat *reclines* very far, but it does not fold perfectly flat to make a continuous table-top like a truck. You get a step/bump where the seatback meets the folded rear seat, and the passenger footwell is lower than the cargo floor. You need 98" of *flat, fully supported* length, and you need 100" if you keep it in the box. You are 3-6" short, and that is before you account for: 1. The box can't go all the way to the very latch - you lose 1-2" to the hatch plastic / weatherstrip 2. You can't get the nose all the way to the firewall - the dashboard, glovebox and windshield angle get in the way 3. The KARLBY is 25 5/8" wide, heavy particleboard-core veneer. It cannot be bent, bowed, or fed in diagonally like a 2x4. It has to stay flat and supported or it will crack/snap at an unsupported point, and the veneer edges dent very easily. You *can* wedge an 8-foot 2x4 or pipe diagonally in a Fit if you run it from the driver-side rear corner into the passenger footwell and let it ride up onto the dash. People do it for lumber. You cannot do that safely with a 1.5" thick, 26" wide, 60 lb slab of countertop. At an angle it will be: - resting on a point on the dash / windshield risk - flexing under its own weight across the bump between seats - blocking your shifter, mirror, and the passenger airbag - barely fitting through the hatch opening height/width even straight Some people have reported getting a 98" KARLBY *wedged* in a Fit with the hatch bungied closed on blankets for a very short, slow trip, with the nose down in the passenger footwell. IKEA and most owners do not recommend it - you risk breaking the top ($249+ replacement) and damaging the interior. ### What to do instead 1. **Measure yours to be 100% sure:** Fold both rear seats (magic seats down), slide front passenger seat fully forward, recline fully and remove the headrest. Tape from the inside of the closed tailgate to the farthest point you could get the nose without hitting glass/dash. You will get ~92-95" straight. 2. **IKEA delivery** is usually $49-$79 for a countertop and they will bring it flat. Much cheaper than a replacement. 3. **Rent/borrow:** Home Depot / Lowe's pickup truck ($19 for 75 min), U-Haul pickup/cargo van ($19.95 + mile), or any SUV/truck/wagon with >102" interior with hatch closed. 4. **Do not transport it on a roof rack or with the hatch wide open.** The KARLBY needs full-length support. Roof bars alone will snap it, and an open hatch = carbon monoxide + illegal unsecured load in most states. The 74" / 74 3/8" KARLBY fits a Fit easily with room to spare. The 98" does not fit flat and fully enclosed. If you have to do it in the Fit, have it strapped, on blankets, fully supported, with the hatch tied down with only 4-6" of overhang, red flag, local streets only - and accept you may damage it.

Literal evidence from this attempt
The 98" KARLBY will not fit completely inside a 3rd generation 2015-2020 Honda Fit with the hatch closed, and I cannot meet the >90% threshold to answer in the affirmative that it *will* fit.
Exact final answer
The 98" KARLBY will not fit completely inside a 3rd generation 2015-2020 Honda Fit with the hatch closed, and I cannot meet the >90% threshold to answer in the affirmative that it *will* fit. On paper it looks close, but in practice it is too long: * **KARLBY 98":** 98" long x 25 5/8" deep x 1.5" thick. It is rigid - it cannot be bent, angled over a seatback, or folded. * **2016 Honda Fit - published usable length:** * Behind rear seats: ~24-26" * Rear seats folded, to front seatbacks: ~60-68" depending on front seat position * Rear seats folded + front passenger seat slid fully forward / reclined to max recline: ~92-95" on the floor to the dash/instrument panel, ~95-100" diagonally to the windshield footwell corner in most owner measurements. Honda advertised the 2nd generation Fit as ~95" max in Long Mode with the front passenger seat folded flat. The 3rd generation GK5 2015-2020 **removed the front passenger fold-flat feature** - the seat reclines but it does not make a flat, level load floor to the dash, it makes an inclined surface that hits the headrest/headliner before going to horizontal. Even if you recline the passenger seat to its maximum mechanical recline and try to balance the countertop diagonally from the lower-left corner of the tailgate sill to the upper-right corner of the passenger footwell / dash: 1. The effective straight-line clearance with the hatch closed is typically cited by owners and reviewers as 92-95" on the floor, under 100" on a diagonal. 98" is at or over that hard limit. 2. You have to account for the thickness of the hatch, the dash, and the reclined seatback mechanism - the 98" board cannot use every inch of that diagonal because it is 25 5/8" wide and 1.5" thick. It will bind on the hatch pillars and the B-pillar / seat bolster when you try to angle it. 3. Resting a ~70-80 lb rigid wood countertop on a reclined seatback and on the dash/windshield at an angle risks denting the seat frame, cracking the windshield, and creating an unsecured projectile while driving. Honda does not intend cargo to be carried resting on the dash. Forums do report carrying 8 ft / 96" 2x4's *diagonally* with the board supported between the front seats and with padding, often with the hatch barely closed and the board touching the windshield glass. 98" is 2" longer than 8 ft, and the KARLBY is much wider and heavier than a 2x4, so clearance disappears. What owners typically do for a 98" KARLBY in a Fit: * Have IKEA deliver - recommended for KARLBY to avoid cracking * Rent a van/pickup/small truck / cargo van * Have the store cut it to length first if you have the ability to finish the cut edge * Transport with the hatch tied partially open with proper red flag/lighting and legal overhang limits - not fully enclosed, not safe for long highway trips with an unsupported heavy slab If you want to verify your specific car, measure a straight tape from the inside of the closed tailgate sill along the floor, over the folded rear seats, over the reclined passenger seat cushion/bolster to the farthest hard point at the firewall/footwell where the board could actually rest without deforming the seat. In almost all 2016 Fits that measurement to a flat, supported position is under 98".

AI-assisted review

Explicit NO supported by a physical-fit rejection under a closed-hatch assumption, rather than only an inability to reach 100% certainty.

Literal evidence from this attempt
The 98" KARLBY at 98" long x 25 5/8" deep will not fit fully inside a closed 3rd-generation 2016 Honda Fit, even with all rear seats down and the front passenger seat fully reclined.
Exact final answer
NO The 98" KARLBY at 98" long x 25 5/8" deep will not fit fully inside a closed 3rd-generation 2016 Honda Fit, even with all rear seats down and the front passenger seat fully reclined. The Fit's maximum flat floor length from the tailgate to the dashboard with the front passenger seat reclined/folded is approximately 92-95 inches in real-world measurements, which is less than 98 inches. Because the countertop is rigid walnut veneer at 1 1/2" thick and 25 5/8" wide it cannot be bent, and its width prevents gaining enough extra length on a diagonal to make up the 3-5+ inch deficit. It would require the hatch to remain open/tied down, roof carry, or delivery - it will not fit fully inside closed.

AI-assisted review

Rejects a closed-hatch, no-damage move using its claimed maximum Long Mode diagonal and assumption that the US front passenger seat cannot form a flat shelf. Acknowledges hatch-open transport but warns about support, damage, and exhaust intrusion.

Literal evidence from this attempt
No - not with the hatch closed.
Exact final answer
No - not with the hatch closed. It's too long for a 3rd-gen GK5 Fit (2015-2020). Your math is right: * KARLBY 98": **98" = 248.92 cm long x 25.625" = 65.0875 cm deep x 1.5" = 3.81 cm thick** * 2016 Honda Fit, overall outside: 160.0" = 406 cm long, 67.8" = 172 cm wide. Usable *inside* is much less. ### Usable interior length in a 2016 Fit Honda's 3rd-gen US Magic Seat has: * Utility Mode (rear seats folded flat): cargo floor length ~ 59-62" / ~150-157 cm * Long Mode (rear seats folded + front passenger seat slid all the way forward and reclined as far as it will go) : **~ 68-70" / ~173-178 cm of flat floor, ~94.5" / ~240 cm if you measure diagonally from the passenger footwell / dashboard to the lower corner of the tailgate opening** This generation **does not** have Refresh Mode in the US, so the front passenger backrest does not fold flat to make a true flat shelf front-to-back like the 2007-2008 Fit did. That gives you: * Floor straight: ~62" max vs. 98" needed - short by ~36" / ~91 cm * Floor diagonal: `sqrt(68^2 + 42^2)` = ~80" / 203 cm vs. 98" - short by ~18" / 46 cm * Maximum 3D diagonal from passenger footwell over the seats to the roof corner at the tailgate: ~88-95" / 224-241 cm - still ~3-10" / 8-25 cm short of 248.92 cm In other words, even in Honda's own published Long Mode, the car is rated for about 7'8" / 233-240 cm of angled length. Your KARLBY is 8'2" / 248.92 cm of **rigid** countertop that cannot bend, flex, or be angled sharply without cracking the walnut veneer / particleboard core. Width/depth and thickness are not the problem: * Deep: 25.625" / 65.0875 cm - fits between wheel arches (~40-42" / 100-106 cm) and tailgate opening (~48" / 122 cm wide) * Thick: 1.5" / 3.81 cm - no issue * Height under cargo cover: ~29-32" / 74-81 cm - no issue Length is the dealbreaker. You would have the hatch open by 12-18" / 30-45 cm, plus the thickness of any blanket/support. You can't safely cantilever a KARLBY that far unsupported. It's ~60-70 lbs / 27-32 kg and must stay fully flat and supported over its entire length or it will warp / crack, and IKEA's warranty does not cover cutting / transport damage. ### What to do instead 1. **IKEA delivery:** usually $29-$79 depending on distance for a parcel this size / weight 2. **Rent a pickup / cargo van:** Home Depot, U-Haul, Penske cargo van all have 8'+ flat floor. Lay it flat on blankets, fully supported, face-up. 3. **Roof rack - not recommended:** At 98" it would overhang the Fit's ~65" roof by a lot and requires a full lumber rack with crossbars rated for the weight and proper flag/light laws. A bare roof + foam blocks is not safe for this weight. 4. **Cut first:** IKEA can cut KARLBY to length in-store in many locations if you provide finished length. A 74" KARLBY *will* just barely fit diagonally in a Fit with front seat forward on a flat blanket. If you absolutely have to move the 98" with the hatch strapped open and a red flag/light, you are technically under most state 3-4 ft rear overhang limits, but Honda advises against driving with the hatch open due to exhaust intrusion, and you risk destroying both the car interior and the countertop. For a closed-hatch, no-damage move: you need a longer vehicle.

AI-assisted review

Rejects closed-hatch fit, assuming the front passenger seat cannot create a flat cargo extension and the wide slab cannot use the narrow-object diagonal; allows protruding hatch-open loading with safety caveats.

Literal evidence from this attempt
No — not with the hatch closed.
Exact final answer
No — not with the hatch closed. A 98" KARLBY is too long to fit *inside* a 3rd-gen (2015-2020) Honda Fit, even with the Magic Seat down. Here's why: ### 1. How big the KARLBY 98" really is * **98" L x 25 5/8" D x 1 1/2" thick** — and it's rigid, you can't bend it, fold it, or coil it. It weighs about 65-77 lbs depending on the veneer. You have to get all 98" in a straight (or nearly straight) line inside the car. ### 2. How much room a 2016 Fit actually has Honda specs / owner measurements for 3rd-gen Fit (GK5): * Overall exterior length: 160" * Cargo floor with rear seats folded: **~57-62" long** from hatch lip to the back of the front seats when the front seats are in a normal driving position * Even with the passenger front seat slid all the way forward: **~70-76" long** on the floor * At its narrowest (between the wheel wells): **~40-41" wide** * Hatch opening: **~39-42" wide x ~28-30" tall** * Interior height with hatch closed: **~30-38"** IKEA lists these as parcel dimensions, but the countertop itself is that size. You would need to make 98" fit in ~60-76" of floor. You can't just tilt it up inside the cargo area to make it fit, either: If you try to keep it only in the cargo area and angle it from floor to ceiling: horizontal needed = 98" x cos(theta) = 60" -> theta = ~52 degrees -> vertical height needed = 98" x sin(theta) = ~77" You only have ~30-38" of vertical height. You would hit the roof long before you cleared the hatch. ### What about going diagonal, front-to-back through the whole cabin? This is how people get 8ft 2x4s inside a Fit — they run a *narrow* board from the passenger footwell, between the two front seats, to the opposite rear corner. That works for a 1.5"-wide 2x4, but it does **not** work for a KARLBY: 1. **Width:** 25 5/8" wide has to go somewhere. It won't fit *between* the front seats and over the center console. It has to lie flat across the width of the car. At that width, you can't snake it around the B-pillars and headrests. 2. **No flat front seat:** The 2016 Fit's front passenger seat reclines, but it does not fold flat forward into a table like some Fits/Jazzes in other markets. You don't get a continuous flat floor from the dashboard to the hatch. 3. **Max diagonal:** Even measured corner-to-corner, firewall to the top corner of the hatch on the opposite side, owners report a max usable diagonal of about 90-95" for a narrow object. A 25.6" wide slab cuts that diagonal down by 10"+ because you can't use the absolute corners. The 74" KARLBY (74" x 25 5/8") is a tight squeeze even then. The 98" is 2 feet longer. ### Can you do it with the hatch open? Technically you can have it stick out 20-30" past the bumper if you: 1. Fold both rear seats completely flat, slide passenger seat forward 2. Pad the countertop extremely well - KARLBY corners and veneer damage very easily 3. Support it so it doesn't flex and snap in the middle (it is particleboard under the veneer) 4. Strap it down securely to tie-down points, not just the hatch latch 5. Tie the hatch down as far as it will go, flag the overhang with a red flag/cloth, and stay off the highway Most states/provinces only allow 3-4 ft of overhang with a flag in daylight, and it's still not safe or legal everywhere, and exhaust fumes will enter the cabin with the hatch open. IKEA also specifically tells you not to transport countertops unsupported. Don't put it on the roof rack: 98" with a 3 ft overhang front and rear, 25" wide as a sail, and ~70 lbs with no internal roof support will flex, catch wind, and void insurance if it flies off. ### What to do instead * IKEA delivery - usually $49-$79 for countertops, and they will bring it flat * U-Haul / Home Depot / Lowe's pickup rental for an hour (~$20) * Borrow a pickup, minivan (Odyssey, Sienna, etc. with 4x8 sheet capacity), small SUV with 8ft floor, or small cargo van If you want to double-check your specific car, measure from the *firewall in the passenger footwell* to the *inside top corner of the closed hatch* on the driver side. If that number is not comfortably over 100" (to allow for padding/angle), a 98" rigid slab 25.6" wide will not close.

AI-assisted review

Explicitly rejects fully enclosed fit, with the final conclusion restricted to flat closed-cabin load length. Assumes limited front-passenger-seat folding on most US third-generation trims. Acknowledges a possible 100–105-inch three-dimensional air-line, then raises support, damage, and safety objections without establishing slab fit on that path.

Literal evidence from this attempt
A 98" KARLBY will not fit fully enclosed as a rigid object in a closed 2016 Fit.
Exact final answer
A 98" KARLBY will not fit fully enclosed as a rigid object in a closed 2016 Fit. You will need delivery, a roof rack/trailer, or a larger vehicle / open hatch with proper tie-down and flagging - which is not recommended for a heavy finished countertop. Do not use Honda's 16.6 cu ft / 52.7 cu ft cargo volume. Volume is about small boxes, not a single 98" x 25-5/8" x 1-1/2" rigid rectangle that cannot bend, fold, or telescope. ### 1. Why it's a geometry problem, not a volume problem IKEA KARLBY 98" is listed as: 98" to 98-3/8" Long x 25-5/8" Deep x 1-1/2" Thick, ~ 244-249cm x 65cm x 3.8cm, ~60-75 lbs. As a rigid rectangle its diagonal is: sqrt(98^2 + 25.625^2) = ~101.3" You need a straight, unobstructed line ~98" long in one direction and ~25.6" in the other, plus room to get it through the door/hatch aperture and around wheel wells, seat brackets, center console and roof. Thickness is not the limiter here, length is. ### 2. What a 3rd-gen Fit actually offers 2016 Fit - 160" overall length, 99.6" wheelbase: * max width at hatch: ~48-52" * width between wheel wells: ~40-41" * floor to roof at hatch: ~34-38" * hatch opening height: ~26-30" usable * floor length, hatch sill to back of rear seats up: ~24-28" * floor length, hatch sill to back of rear seats folded: ~60-67" depending on front seat position * floor length, hatch sill to back of front seats slid fully forward: ~75-80" The 25-5/8" width *will* fit between the wheel wells flat, and can fit through the hatch height if kept flat - 25.6" < ~40" width and < ~30" height. So the cross-section fits. Length is the failure. Honda's "Long Mode" on the 2nd-gen Fit/Jazz advertised ~93-97.6" from dash to closed hatch with the front passenger seat fully folded flat. Honda removed the fully-flat folding front passenger seat on most US 3rd-gen trims 2015-2020. It reclines steeply but does not make a flat, continuous load floor to the dashboard. Even in the European Jazz where Honda claims ~2,400-2,480mm / ~94-97.6" in Long Mode: 98" to 98-3/8" > 94-97.6" You are 1/2" to 4" too long to close the hatch on a flat floor, before accounting for the dashboard thickness, head restraint, and the raised hinge/seat-bracket hump where the rear Magic Seat folds. You cannot gain it back by turning the board on its 25-5/8" edge to use height. Interior height is ~35" - standing it on the 98" x 1.5" edge still needs 98" fore-aft. Leaning it from floor to roof on a hypotenuse only adds ~2-5" effective length: e.g. 80" floor + 20" rise = sqrt(80^2+20^2) = 82.4". You cannot gain it back by diagonaling in plan view either. You would need to put the 101.3" diagonal of the board on the diagonal of the car, which then requires ~25.6" of clear width at both ends at the same time. The Fit tapers at the dash, center console intrudes, and the hatch aperture is narrower than the cabin max width, so you cannot swing a 101" diagonal through the hatch opening without hitting. In practice owners consistently report ~72-74" fits easily flat with seats folded, ~ 90-94" is absolute max with front passenger moved fully forward and reclined and cargo resting on top of the folded seatback - not flat, not supported, and risky for a finished veneer top. 98" does not clear with the hatch latched. Can you wedge it from the top of the closed hatch glass to the passenger footwell diagonally in 3D and bungee the hatch? Physically you might get ~100-105" of air-line, but: 1. It will not be flat or supported - it will point-load on the dash, seatback latch, and hatch trim and will crack the particleboard core or chip the veneer. 2. You cannot see out the rear and it becomes a projectile in a stop. 3. You will have to force it past the hatch striker and risk tearing the weatherstrip, headliner, and plastic. IKEA ships KARLBY flat and explicitly warns not to flex it. ### 3. Quick self-test before you try If you want to verify your specific car: 1. Fold rear Magic Seat flat. 2. Slide front passenger seat fully forward and recline as far as it will go, remove head restraint if allowed. 3. With hatch closed, measure with a tape from inside of hatch plastic at floor height to the first hard obstruction forward - front seatback, console, or dash - keeping the tape flat and horizontal, ~25" off center to simulate board width. You will measure ~75-85" on most US 2016 Fits, ~93-96" at best if your front seat goes unusually flat. You need 98" + 1-2" clearance to avoid damage. Also measure hatch opening clear height - if < 26" you can't even slide it in flat without tilting. ### 4. Safer options * IKEA delivery / TaskRabbit: usually $50-$150 for a countertop vs. replacing a $300+ top damaged in a Fit. * Rent a pickup, cargo van, or small U-Haul for an hour. A 98" board fits flat in any pickup with a 6'+ bed with tailgate down flagged. * Roof rack: A Fit *can* carry 98" on crossbars, but overhang laws in most US states are ~3' front / 4' rear max, must be tied at 2 points and flagged/red light at night. Particleboard KARLBY should be kept flat, fully supported and wrapped - not ideal on a small hatchbar spread. Do not drive with the hatch open and board sticking out 18-24" unsecured. Aside from exhaust ingress, it's illegal to obscure plates/lights and creates a major hazard for following traffic. > Bottom line: width and thickness clear, but 98" exceeds the closed-cabin flat load length of a 2016 Fit by several inches even in Long Mode. Plan for delivery or a larger vehicle.

AI-assisted review

The repeated overall no is explicitly limited to safe, no-contact closed-hatch stowage under assumed US-spec seat limitations. It nevertheless admits hatch closure with steep on-edge dashboard/windshield contact and obstructed controls, so this is not an unqualified geometric impossibility claim.

Literal evidence from this attempt
**Stowed fully inside, hatch latched, safely secured, no contact:** No, under assumed stock dimensions.
Exact final answer
A 98" KARLBY will go *through* the hatch hole, but will not fit *inside* a closed 3rd gen. 2016 Fit in a flat, safe, closed-hatch orientation without leaving the hatch ajar and risking damage. That distinction is key for this car. Countertop as given: **98" L x 25-5/8" W x 1-1/2" T**, rigid, no bending, ~65-75 lb. Even with packaging removed you have to account for the full 98" x 25-5/8" rectangle. ### Dimensions I have to assume for a 2016 Fit Honda does not publish full interior box dimensions, so I have to assume typical owner-measured ranges for a US-spec GK5 2016 Fit / Jazz. Measure your car before you try: * **Hatch opening clear:** ~40-43" wide x ~29-32" tall, narrowest between trim. Hatch sill to roof. * **Interior width:** ~50-52" wall to wall at beltline, **~39-40.5" between wheel arches** at floor, ~40-42" between rear door trim. * **Interior floor length, hatch sill to:** 1. back of rear seats up: ~30-33" 2. base of front seatbacks with rear Magic Seats folded flat: ~60-63" 3. dashboard / footwell with front passenger seat pushed fully forward and reclined as far as it will go: ~90-95" horizontal to the dash face, ~94-98" to the lowest point of the windshield * **Front passenger seat:** Important: Unlike the 2nd gen 2009-2013 Fit, the **US-spec 3rd gen 2015-2020 Fit front passenger seat does NOT fold forward flat into a table**. It only slides and reclines ~40-45 degrees. So you do NOT get a flat 7.5-8 ft floor like the old Fit. * **Floor to headliner:** ~29-31" in cargo area If you have a Euro-spec Jazz where the passenger seat does fold fully flat, add ~4-6" to case 3, but the conclusion is still borderline. ### 1. Getting it through the hatch opening: YES, but angled To load lengthwise, the cross-section you have to pass through the hole is 25-5/8" x 1-1/2". Flat: 25-5/8" < 40-43" wide and 1-1/2" < 29-32" tall = clears. Even if you stand it on edge: 25-5/8" < 29-32" tall and 1-1/2" < 40-43" wide = also clears. Diagonal clearance of the hole is sqrt(42^2+30^2) ~ 51", so you have a lot of room to tilt. You can get it in. You are not limited by the hatch hole. ### 2. Finding an orientation inside the cabin with hatch closed: NO / marginal to unsafe The problem is length. 98" has to live on the vehicle's longitudinal axis. Transverse or floor-diagonal won't work: Floor diagonal with rear seats down: sqrt(62"^2 + 40"^2) ~ 74" max. No. So it has to go front-to-back on the passenger side: * Rear seats folded, front seats in normal driving position: ~60-63" floor = **~35" too short.** * Front passenger seat slid fully forward, reclined fully, headrest removed, rear seats folded: ~90-95" horizontal to dash. 98" is already 3-8" too long to lay flat. You would have to wedge the front end *above* the dash, resting on the dash top / against the windshield glass, and the rear end on the hatch sill. You can gain *diagonal* length by going from low at the hatch sill to high on the dash: sqrt(horizontal^2 + vertical^2). Example: 94" horizontal to windshield base + 18" rise to dash top = sqrt(94^2+18^2) = ~95.7". To get 98" you need ~94" horizontal + ~27" vertical, which puts the leading corner into the windshield / A-pillar / headliner / sun visor area. In practice owners report max straight object with closed hatch in a 3rd gen Fit is a 68" - 72" flat-pack, and ~92-94" if you angle up to the windshield and accept contact. An 8 ft 96" 2x4 will not close without forcing. A 98" x 25-5/8" slab is wider than a 2x4 and cannot be tucked into the footwell. That means: * You cannot lay it flat on the folded Magic Seat floor and close the hatch. * You can only close the hatch if you rest ~100 lbs of particleboard+veneer on edge on the dash, center console, infotainment screen and windshield at a steep angle, blocking the passenger mirror, shifter, and risking a crack or gouge on hard braking. I do not recommend it. * Weight and rigidity also matter - you cannot flex it around the front seat bolster. With the old 2nd gen Fit that folded flat to ~95-100" you could just make it. Honda removed that feature. ### Verdict * **Through the opening:** Yes. * **Stowed fully inside, hatch latched, safely secured, no contact:** No, under assumed stock dimensions. Plan on the hatch being open 24-35" with overhang. Options: IKEA delivery, borrow/rent a small SUV/truck/van, roof rack with proper support - KARLBY must be supported full-length flat and protected from moisture/twist, do not let it flex unsupported - or order the 74" KARLBY which fits easily, or have it cut in-store if you accept a seam. If you must try: bring moving blankets, remove rear headrests, slide passenger seat fully forward/up, recline as far as possible, pad the dash/windshield, and plan to strap the hatch down ajar with a ratchet strap + red flag - check your state law for rear overhang, lights obscured, and exhaust fumes with hatch ajar.

AI-assisted review

Explicit no assumes fully enclosed, safely hatch-closed transport and a 90–95-inch maximum with the front passenger seat reconfigured; acknowledges hatch-open transport rather than denying every transport possibility.

Literal evidence from this attempt
NO, the 98-inch KARLBY is longer than the 2016 Honda Fit's maximum enclosed floor length of about 90-95 inches even with the rear seats folded and front passenger seat folded flat/reclined to the dashboard.
Exact final answer
NO, the 98-inch KARLBY is longer than the 2016 Honda Fit's maximum enclosed floor length of about 90-95 inches even with the rear seats folded and front passenger seat folded flat/reclined to the dashboard. Its 25 5/8-inch depth and rigid construction prevent gaining enough length diagonally to close the hatch safely. You would need to transport it with the hatch open, which is not recommended, so use delivery, a roof rack with proper support, or a larger vehicle.

AI-assisted review

Explicitly rejects every fully enclosed orientation, assuming at most 95.5 inches with the passenger seat folded and claiming the slab width defeats diagonal alternatives.

Literal evidence from this attempt
**Conclusion: There is no orientation that allows the 98" x 25.625" slab to be fully enclosed with doors/hatch closed.**
Exact final answer
A 98" KARLBY will not fit fully inside a 2016 Honda Fit with the hatch closed - even with maximum interior length - based on dimensions alone. Here is the independent analysis: ### 1. KARLBY 98" As you listed: - **Length: 98"** (8'2") - **Depth/Width: 25 5/8" (25.625")** - **Thickness: 1 1/2" (1.5")** - Weight: ~55-80 lbs depending on veneer, particleboard core The critical dimension for fitting is 98" long, and the 25.625" depth prevents much diagonal angling. IKEA lists it as 98 7/8" for some finishes, which would be even longer, but using your 98" figure: ### 2. 2016 Honda Fit (3rd gen) Interior Cargo Envelope The Fit is subcompact, total exterior length is 160" (13'4"), but interior cargo length is much less. Measured usable floor space with all Magic Seats down: - **Behind rear seats, seats up: ~28-30" long** - **Behind front seats, rear seats folded, front seats in normal position: ~60-68" long** - **Maximum floor length, rear seats folded + front passenger seat folded flat forward to dashboard: ~92" to 95.5" long** depending on measurement point (Honda / Edmunds / owner measurements all cluster around 94-96") Other limiting points: - **Width between wheel wells: ~39.5" - 41"** - **Maximum interior width at floor: ~50-51"** - **Hatch opening width: ~43-46"** - **Hatch opening height: ~28-30"** So even in its longest possible configuration - rear seats flat, front passenger seat folded flat forward, countertop slid forward to the dashboard - you only have ~95.5" of straight-line length to work with. > 98" > 95.5" — it is ~2.5-6" too long to close the hatch in a straight line. ### 3. Can you cheat it diagonally? For a rectangle (98" x 25.625") to fit inside a larger rectangle (L x W), you need both: 1. `l*sin(theta) + w*cos(theta) <= W` 2. `l*cos(theta) + w*sin(theta) <= L` Using the absolute best case L=95.5", W=51" (widest point, not the narrow wheel wells): No angle satisfies both. For example at 15 degrees of angle: - Width needed = 98*sin(15) + 25.625*cos(15) = ~50.1" (barely fits width) - Length needed = 98*cos(15) + 25.625*sin(15) = ~101.3" > 95.5" (fails length) At any greater angle to reduce length, width required exceeds 51", and at the narrower wheel-well point (~40") you have even less diagonal room. The thickness (1.5") doesn't help, and you cannot stand it on edge diagonally because then height becomes the limiter and the 25.625" dimension is still too tall for the hatch opening. **Conclusion: There is no orientation that allows the 98" x 25.625" slab to be fully enclosed with doors/hatch closed.** ### Options if you have to move it with a Fit: 1. **Do not try to force it on an angle unsupported.** KARLBY is particleboard with veneer - it will crack if flexed or if supported only at two points with 98" of span while driving. 2. **Hatch-open carry is not recommended:** You would have 3-8" protruding past the bumper. Most states require a red flag/light for any load protruding >3-4 feet, and even a few inches with the hatch bungeed down is unsafe (exhaust ingress, visibility, sudden stop). Check local law first. 3. **Better options:** IKEA delivery ($30-$50 for parcel/large usually), rent a Home Depot/Lowes/U-Haul cargo van or pickup for ~$20-30 + mileage, borrow a roof rack with crossbars and full support (needs 8'+ flat support, not just two bars), or have IKEA / a lumberyard cut it - though IKEA does not cut KARLBY in store. If you want to verify yourself, measure from the closed tailgate (inside) to the back of the front passenger seat folded flat forward. If that number is under 98", it won't close.

Rejects fully enclosed fit, claiming the US third-generation passenger seat lacks flat Long Mode and width defeats diagonal loading; requires an open hatch instead.

Literal evidence from this attempt
No — that countertop will not fit fully inside a 3rd-gen 2016 Honda Fit with the hatch closed, even though it's a very versatile little cargo hauler.
Exact final answer
No — that countertop will not fit fully inside a 3rd-gen 2016 Honda Fit with the hatch closed, even though it's a very versatile little cargo hauler. Here's why, assessed independently from your guess: **1. The countertop:** 98" long x 25 5/8" deep x 1 1/2" thick is correct for the large US KARLBY. That's 8'2" long, rigid, heavy at 60+ lbs, and cannot be bent or flexed. **2. The 2016 Fit:** The 3rd-gen Fit is about 160" long overall on the outside. Inside, with the rear seats folded flat: * Floor length from the closed tailgate to the back of the front seats: ~60-68" depending on front seat position * Width between wheel wells: ~40-41", wider up higher at ~50-55" * Max usable floor-to-dash length with the front passenger seat pushed all the way forward and reclined: ~90-95" on a straight line Unlike the 2nd-gen Fit, the US 3rd-gen does not have a front passenger seat that folds completely flat into a "long mode," so you don't gain the extra length older Fits had. That means you are about 3-8" short on straight length for a 98" rigid board, and you can't make it up by going diagonally because the KARLBY is also 25 5/8" wide. Angling a board that wide and thick inside the Fit's ~50" max interior width eats up the diagonal length you would need — plus door panels, pillars, and the dashboard prevent you from using corner-to-corner. In forums, people do get 8 ft / 96" lumber in a GK Fit, but only diagonally, wedged from the passenger footwell to the rear corner, and often with the hatch still barely closing and risking damage to the dash. At 98" plus 25 5/8" width and 1.5" thickness with no flex, the KARLBY is larger in every dimension than that trick allows. ### What will work instead: 1. **Measure to be sure:** Run a tape from the inside of the closed tailgate to the dashboard/passenger footwell in your specific car at the height the countertop would ride. You'll see ~90-95" max. 2. **Use an alternative for this trip:** IKEA delivery, rent a pickup/small van from Home Depot/U-Haul/Lowe's, use a roof rack rated for the length/weight, or have it cut to size at the store if your kitchen layout allows. 3. **Don't drive with the hatch open / countertop sticking out** unless it's properly supported, flagged, and strapped per your local laws — an unsupported 98" veneer top will bounce, crack, and is a hazard. If you want to carry it yourself in the Fit, you would need the hatch secured open, which is not "fitting inside" and is not recommended for a heavy, finished countertop like the KARLBY.

Concludes the rigid slab cannot fit in the closed cabin because its width blocks the rotations available to a narrow pole, even using the front footwell; distinguishes hatch-ajar transport from inside fit.

Literal evidence from this attempt
* Fully enclosed, hatch closed, flat, undamaged: **No.**
Exact final answer
98''x25.6''x1.5'' will not go in a US spec 3rd gen `GK5` Fit/Jazz closed as a rigid plane. The strongest `it will not fit` argument is this one: * Floor to back of front seats in cargo mode: $\approx$ 62-68'' L x 40.5'' between wheel houses, 53'' max width x $\approx$ 39'' H to headliner * Space diagonal of the biggest rectangular prism you can inscribe in the cargo only: $$\sqrt{L^{2}+W^{2}+H^{2}} = \sqrt{62.8^{2}+53^{2}+39.5^{2}} \approx 91''$$ $$98'' > 91''$$ so not even the {\it line} fits, much less the rectangle. Even if you use the whole cabin to the footwell you have to solve the plate in a box problem. A $98 \times 25.625$ rectangle at an angle $\theta$ to the long axis needs $$L_{proj}=98\cos\theta + 25.625\sin\theta \le L_{car}$$ $$W_{proj}=98\sin\theta + 25.625\cos\theta \le W_{car}$$ $$H_{proj}=1.5 {\rm\;to\;}25.625 {\rm \;depending\;on\;tilt} \le H_{car}$$ For $L_{car}\approx 62-68$ cargo only there is no $\theta>0$ that satisfies both. E.g. to get $L_{proj}<68$ you need $\theta > 46^{o}$, then $W_{proj}>70'' >53''$. If you go 3-D, floor at the tailgate to headliner at the windshield, one lower rear corner to the opposite upper front corner: $$D\approx \sqrt{L^{2}+W^{2}+H^{2}}$$ Does that {\it by itself} rule it out? * Cargo only: No. $D\approx 91'' <98''$ - fails on a line. * Cabin to firewall/footwell, front seat full forward, board {\it over} the seats on the dash: Honda advertises Long Mode as $\approx$ 94-96'' floor to dash. $D=\sqrt{\approx 95^{2}+50^{2}+39^{2}}\approx 114''$ as a one dimensional line. On pure line length alone you can get $>98''$ corner to corner, tailgate floor to passenger footwell to headliner, so the $98''>L$ objection alone would {\it not} strictly rule out a $1''\times 98''$ pole. What does rule it out closed is the second dimension. $25\,5/8''=650mm$ is not a pole, it is a plate. To get the length you have to keep the plate almost flat horizontal, so you cannot use $H$ to increase $D$, and to get $W_{proj}$ down you have to keep $\theta$ small, so you cannot use $W$ to increase $D$ either. With any $\theta$ that makes $L_{proj}$ short enough to fit between the tailgate and the B-pillar/dash, $W_{proj}$ is $60-71''$, far wider than the $40-53''$ available at beltline, and wider still than the roof which tapers to $\approx 38-42''$ at headliner height, and you cannot tilt the $25.6''$ dimension vertical because then $H_{proj}=25.6''$ plus the need to clear the wheel houses, seat bolsters, C-pillars and headliner leaves no rotation freedom. In other words: a $98''$ line can be threaded diagonally from the passenger footwell to the rear hatch, which is why people do carry $8'0''$ $2\times 4$'s that way. A $98''\times 25.6''$ rigid rectangle cannot be inscribed in any horizontal or diagonal cross-section of a closed GK Fit. Result: * Fully enclosed, hatch closed, flat, undamaged: **No.** * With front seat full forward/reclined, board over the seat, one end on the dash/in footwell, other end cornered to the hatch, hatch tied down ajar 6-10'': routinely done, but that is not ``inside.'' If you must move it in the Fit, plan on hatch-ajar tied down with padding, or roof rack/trailer, or have IKEA cut to size.

Rejects even diagonal fit with the hatch closed, adding a flat-support requirement and treating Long Mode's claimed narrow length as the maximum diagonal.

Literal evidence from this attempt
A 98" KARLBY will not fit *inside* a closed 3rd generation Honda Fit, even diagonally.
Exact final answer
A 98" KARLBY will not fit *inside* a closed 3rd generation Honda Fit, even diagonally. Here is why, without using made-up numbers: **1. What you are trying to fit:** 98" L x 25 5/8" W x 1 1/2" thick. That's a rigid, flat, non-bendable rectangle that must be supported flat. It weighs ~65-75 lbs. The packaged length is actually slightly over 98". **2. What a 2016 Fit actually has:** Honda does not publish an official "maximum interior diagonal" or "maximum floor length to dashboard" spec. What Honda *does* publish for a 2016 Fit: * Overall exterior length: ~160.4" * Cargo volume: 16.6 cu ft rear seats up, 52.7 cu ft rear seats folded * Cargo floor length behind the rear seats: only about 36-42" depending on front seat position What third-party tests and Honda's own "Magic Seat / Long Mode" description show: * With both rear seats folded down, usable *flat* floor length from tailgate to the back of the front seats is only about 60-68" in the US model. That's the largest full-width, full-height rectangle. * With the front passenger seat moved fully forward and reclined/angled to create Honda's "Long Mode," Honda and reviewers have listed a maximum narrow, angled length of about 92-95" from the tailgate to the dashboard/windshield. This is NOT a flat, full-width floor - it is a sloped, narrow channel over the folded front seat, interrupted by the center console, door armrest/door panel, and dashboard shape. Even if you counted that absolute maximum narrow channel, 92-95" < 98". **3. Does diagonal help?** No, not enough to overcome an ~30" deficit, because: *On the flat cargo floor only:* If the flat floor is roughly ~60-68" long x ~40-48" wide between the wheel arches/walls, the floor diagonal is: sqrt(L^2 + W^2) = roughly 72" to 83". Still ~15" to 26" short of 98". You cannot gain enough length from width to fix a 30" length shortfall when the box itself is 25 5/8" wide - the countertop's own width prevents you from using the extreme corner-to-corner point of the car. A 25.6" wide board cannot be pushed into a triangle point; it needs rectangular clearance. *In 3D, floor-to-ceiling:* Even a 3D corner-to-corner diagonal from the cargo floor to the headliner is only in the low 80" range on flat-floor-only, and requires tilting the countertop at a steep angle. A 98" x 25.6" slab tilted that steeply will hit the headliner, hatch opening, and front seats, and cannot be angled enough to close the hatch. *Using the Long Mode to the dashboard:* You do gain length by extending to the dashboard, but you *lose* usable width and flatness. That ~92-95" figure *is already* the longest possible diagonal/angled line Honda intends, measured at the narrowest point over the front seat. It accounts for diagonal use. Since 95" < 98", it still does not fit, and even that 95" is not a flat 25.6"-wide support - the countertop would be resting at an angle on the console and door trim, with stress on the middle, risking cracking. There is also no way to put it diagonally across the *width* of the car to gain length - the Fit is only ~50-55" wide at the beltline inside, far narrower than the countertop is long. **Conclusion:** With the hatch able to close and the load fully inside and properly supported, 98" > the longest usable straight line in the car. Do not transport it hanging out the hatch or window - that's unsafe, illegal beyond a small overhang in most states without proper flagging/lighting, and will damage the particleboard core of the KARLBY. Options: 1. Use IKEA delivery / truck rental - this is what IKEA designed the 98" size for. 2. Rent a cargo van, small pickup with 8' bed, or U-Haul/Home Depot truck for one trip. Even many small SUVs will not fit this closed either. 3. Buy the shorter KARLBY - 74" - which *will* fit in Long Mode in a Fit with proper padding, or plan to cut the 98" down before transport - only if you have the tools to properly cut and reseal a wood veneer countertop. If you want to verify yourself, don't measure corner-to-corner with a thin tape - measure the largest *rectangle* 25 5/8" wide that can lay flat from the tailgate forward without bending or resting on trim. You will see you run out of flat support well before 98".

AI-assisted review

Gives a clear probable negative for fully enclosed, flat transport despite lacking an exact factory length. It rules out diagonal rescue by assuming the slab must remain essentially level to avoid obstructions and breakage.

Literal evidence from this attempt
A 98" KARLBY will very likely **not** fit fully inside and flat with the hatch closed in a 2016 Fit, but you shouldn't treat that as proven without measuring your car, because there is no single reliable factory number for this.
Exact final answer
A 98" KARLBY will very likely **not** fit fully inside and flat with the hatch closed in a 2016 Fit, but you shouldn't treat that as proven without measuring your car, because there is no single reliable factory number for this. Here is what we do and don't know: **1. What we know for sure:** * KARLBY 98" = **98" L x 25 5/8" D x 1 1/2" H** - rigid, cannot be bent, folded, or stood on edge for long without risk of cracking the particleboard/veneer. * 2016 Honda Fit 3rd gen exterior length is ~160.0" overall. So 98" is shorter than the *outside* of the car, but that doesn't mean it fits *inside* as usable space. * Weight is not the issue - that top is ~60-70 lbs, well under the Fit's payload. * Width/depth and thickness are not the issue. The cargo floor between the wheel wells and with the rear Magic Seats folded is wide enough for 25 5/8". Length is the only problem. **2. What is *unknown* / not reliably published:** Honda does not publish an official, standardized "maximum interior load-floor length with hatch closed." What Honda *does* publish is total cargo volume: 16.6 cu ft seats up, 52.7 cu ft seats down. That's volume, not length. For length, we only have: * conflicting third-party reviewer measurements for floor length with rear seats folded (typically ~57" to ~62" from the back of the front seats to the hatch), and * Honda marketing claims for "Long Mode" - where you fold the front passenger seat flat + fold the rear seats - often quoted as up to ~7' 9" to 7' 10" [93" to 94"] of *usable* length from the dashboard to the hatch. I cannot verify that to factory-spec accuracy for a 2016 US trim, and it varies by how far forward/reclined your front seat is, and whether your specific trim has the flat-folding front passenger seat. I do **not** have a reliable OEM tape-measure diagram that says "distance from firewall / dashboard edge to inside of closed hatch at floor height = X inches." Without that, I can't prove definitively from a spec sheet alone that 98" *cannot* fit, and you shouldn't treat "no spec found" as proof either way. **3. Practical assessment:** To carry a 98" rigid board flat and fully enclosed, you need a continuous, flat, unobstructed 98" line at a height where the 25 5/8" width + 1.5" thickness can sit. In a Fit that requires: * rear seats folded flat * front passenger seat folded flat / slid far forward and reclined (if equipped with Long Mode) * board going from the dashboard / windshield base area all the way to the closed hatch, staying level Even using Honda's most generous Long Mode marketing claim of ~93"-94", you are still ~4-5" short of 98". Real owner reports are that an 8-foot 2x4 or 98" countertop sticks out several inches and requires the hatch to be tied down ajar. You cannot make it up with a diagonal: * Floor-to-ceiling height inside is only ~38-40", so floor diagonal doesn't add much. * Windshield-to-hatch diagonal *is* longer, but you can't use it because the countertop has to stay essentially flat and level - tilting a 25 5/8" wide, 98" long slab up to the windshield will hit the roof, headrests, and windshield, and will put all the weight on 2 points, risking breakage. In other words: unknown spec aside, all geometry and real-world reports point to 98" > usable flat length with hatch closed. **What to do if you want to be certain:** Measure your specific car with a tape measure before you buy/pick up: 1. Fold rear seats, slide front passenger seat fully forward and fold flat/recline as far as it will go. 2. Measure from the farthest forward hard point the countertop would touch (dashboard / base of windshield) to the inside plastic of the closed hatch, keeping the tape level at the height the countertop would ride. 3. Do it at both floor level and at ~12-18" up, where the seatbacks create a hump. The shortest number is your limit. 4. Allow 1-2" clearance so you don't crack the veneer on the hatch latch. **Safer options for that top:** * IKEA delivery * Rent a pickup, small van, or utility trailer - a 98" top fits easily flat in those * Carry in the Fit with hatch tied ajar with ratchet straps/red flag and proper overhang support - legal in many states for a few inches, but not fully "inside," not weather-proof, and not ideal for a heavy, damage-prone countertop If you already own the Fit and want me to help interpret a measurement you take, send me the floor-length and dash-to-hatch numbers and I'll tell you the clearance.
