Enter your couch dimensions and hallway corner measurements — the app calculates whether you can pivot around the turn.
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

Frequently asked
For a standard 84-inch couch, you typically need at least 42 inches in both corridors for a flat pivot. If one corridor is narrower, tilt the couch vertically to reduce the footprint. The wider the corridors, the easier the turn.
01The moving sofa problem is a famous math puzzle about finding the largest shape that can navigate an L-shaped hallway corner. In practice, the answer depends on your specific couch dimensions and hallway widths. Our calculator handles the real-world version of this problem.
02Yes — standing a couch on end dramatically reduces the floor space needed for the turn. A couch that is 84" long and 35" wide only occupies a 35" × 33" footprint when stood upright. You need ceiling clearance for the 84" length, but the corner pivot becomes much easier.
03Rounded or chamfered corners are easier to navigate than sharp 90° angles. The curved wall acts as a guide rail for the couch. Measure the radius of the curve and the corridor widths on both sides.
