Enter your item dimensions and sedan trunk measurements — the app checks trunk space, seats-folded length, and diagonal loading options.
Whether it fits comes down to the measurements most people skip.
Real openings run about 1 to 2 inches under the labeled size, and a single inch can flip the result. Check your own measurements before you buy or move.
Verdicts compare all six item orientations against the space using verified building standards. See our methodology

|---|---|---|
| Twin38″ × 75″ | Twin in Trunk only: Doesn't fit. | Twin in Rear seats folded: Tight fit. |

A sedan pass-through is ~72" long x ~44" wide x 20-24" tall. Only a folded foam twin travels reasonably; any larger mattress needs an SUV, minivan, or pickup truck.

Most “it didn't fit” stories trace back to one of these oversights.
Frequently asked
A typical mid-size sedan trunk holds 14–16 cubic feet (roughly 42" L × 44" W × 20" H). With rear seats folded, total cargo length extends to 60–72" through the pass-through opening, but the opening is only 20–24" tall. Compact sedans are slightly smaller; full-size sedans (Avalon, Maxima) offer up to 16–18 cubic feet.
01Most modern sedans have 60/40 split-fold rear seats that create a pass-through from the trunk to the cabin. This extends usable length from ~42" to 60–72". Some older or base-model sedans have fixed rear seats with no fold-through. Check your owner's manual for the fold mechanism.
02With seats folded, most sedans handle items up to 72" long × 24" tall × 44" wide. Flat items (lumber, shelving boards, flat-pack furniture) work best because the pass-through height is the main constraint. For anything taller than 24", you need an SUV, minivan, or pickup truck.
03SUVs offer 2–3 times the cargo volume, with cargo heights of 30–40" vs. a sedan's 20" trunk height. For small, flat items (TV boxes, flat-pack furniture, suitcases), a sedan works fine. For anything bulky or tall, an SUV is significantly better. Sedans do handle long, narrow items well through the fold-through pass-through.
