What hallway width do I need to turn a couch around a corner?

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.

What is the "moving sofa problem"?

The 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.

Can I pivot a couch vertically to clear a corner?

Yes — 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.

What if my corner has a rounded wall instead of a sharp angle?

Rounded 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.

Whether it fits depends on measurements most people get wrong.

Key Measurement

Couch length and depth vs. corridor widths at the turn

Standard Dimensions

Item: Standard 3-seat couch: 84" L × 35" W × 33" H

Space: Standard hallway corner: 42–48" wide on each side. Building code minimum: 36" per corridor

Actual clear openings are usually 1–2″ smaller than the labeled size.

Your exact dimensions probably aren't "standard." Small measurement errors cause big problems — 1 inch can be the difference between fitting and getting stuck.

Verdicts are calculated by comparing all 6 item orientations against the space dimensions using verified building code standards. See our methodology

Measure smart

What to measure.

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

01Corner pivot math: sofa length × depth together determine the minimum corridor widths — longer and deeper sofas need wider corridors on both sides
02Inside wall clearance at the pivot point — this is where the sofa's midsection presses closest to the wall during the turn
03Outside wall clearance — the sofa ends sweep outward during the pivot and can hit the far wall if corridors are narrow
04Whether furniture sliders are available — they protect the wall and floor at the pivot point where concentrated pressure causes damage

Don't make these

Common mistakes.

Most “it didn't fit” stories trace back to one of these oversights.

⚠Only measuring one corridor width — asymmetric hallways are common in older buildings, and the narrower side controls the pivot
⚠Ignoring sofa depth when calculating pivot clearance — a 36"-deep sofa needs substantially wider corridors than a 30"-deep one at the same length
⚠Assuming a flat carry works at corners — most 90° turns require tilting the sofa vertically or angling it through at a steep pitch
⚠Not protecting the wall at the pivot point — the corner takes all the contact pressure, and drywall dents easily under a 100+ lb sofa edge
