Enter your couch dimensions and staircase measurements to find out — landings, turns, and banister clearance included.
Whether it fits depends on measurements most people get wrong.
Landing depth and width vs. couch dimensions when tilted on end
Item: Standard 3-seat couch: 84" L × 35" W × 33" H
Space: Standard residential staircase: 36" wide, 80" ceiling clearance, 36" landing depth minimum
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

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, if the landing is wide enough. Stand the couch on its end and pivot it around the inside corner. You need at least 40 inches of landing depth for a standard 3-seat couch. Having one person above and one below helps control the angle during the turn. The technique varies by stair type — L-shaped and U-shaped landings each require different pivot strategies.
01Yes — removing legs reduces height by 4–6 inches, which helps at ceiling overhangs and landing turns. Most sofa legs unscrew by hand. Also remove any loose cushions to reduce weight and bulk.
02Most wooden banisters are bolted at the top and bottom with lag screws. Removing a banister adds 3–5 inches of usable width. Mark bolt positions before removal so you can reinstall it afterward. Metal railings may be welded and harder to remove.
03Professional movers tilt the couch on its end, wrap it in moving blankets, and use shoulder straps to distribute the weight. They feed the top through first at landings, using one person to guide from above and one to push from below. For tight turns, they may temporarily remove banisters.
