Enter your mattress size and elevator measurements — the app checks the door opening, cab interior, and best loading orientation.
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

Four numbers decide nearly every fit check. Get these right and the rest follows.

Most “it didn't fit” stories trace back to one of these oversights.
Frequently asked
Yes — stand the queen mattress on its long edge. It's only 10–14 inches thick in that orientation and fits through any standard elevator door (36" wide). The 80-inch length must clear the door height (typically 80"), so you may need to tilt slightly.
01A king mattress (76" × 80") on its long edge is 10–14" thick — it fits through the elevator door. The challenge is the 80" length vs. 80" door height, which is very tight. Use a freight elevator if available, or tilt the mattress at a slight angle.
02Yes — all-foam and memory foam mattresses can be folded or rolled. Use ratchet straps to keep it compressed. This is especially useful for tight elevator doors. Do not leave it folded for more than a few hours.
03Angle the mattress diagonally through the door opening. The diagonal of a standard elevator door (36" × 80") is about 88 inches — enough for most mattresses. Once inside the cab, you can reposition the mattress upright if the cab is taller than the door.
