The app checks each section of your sectional against your doorway — piece by piece, no guesswork.
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.

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
Most modern sectionals are designed to separate. They use hook-and-latch connectors, bolts, or clips between sections. Check underneath the cushions at each joint for the connection mechanism. A few budget models are built as one solid frame and cannot be taken apart.
01The corner section (or chaise) is almost always the largest and most difficult piece. It is wider and deeper than the armless middle sections. Check standard sectional dimensions to estimate piece sizes, then measure this piece first — if it clears the door, the rest will too.
02Removing legs reduces height by 4–6 inches, which helps when tilting the section on its side. Most sectional legs unscrew by hand or with a wrench. Remove them before attempting the doorway and keep track of any bolts or mounting hardware.
