Enter your sofa dimensions and staircase measurements to find out — landings, turns, and banister clearance included.
Whether it fits depends on measurements most people get wrong.
Sofa length vs. landing depth and stair width
Item: Standard 3-seat sofa: 72–96" L × 30–40" D × 30–38" H, 100–200 lbs
Space: Standard residential staircase: 36" wide, 80" ceiling clearance
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

Standard sizes say it works — but your measurements are what matter.
Moving a 200-pound dresser or appliance upstairs without injury requires the right technique and equipment. Here's how professionals do it safely.
Most people measure stair width and call it done. The landing, ceiling height, and turning angle are where furniture actually gets stuck.
Your couch is wider than your door. Here are 7 proven techniques to get it through — from tilting angles to door removal to the pivot-and-slide method.
For moving purposes, "sofa" and "couch" are interchangeable — both refer to multi-seat upholstered seating. The key dimensions are length (typically 72–96"), depth (30–40"), and height (30–38"). Our couch up stairs calculator uses the exact same math and applies to sofas as well.
Yes — removing the legs saves 4–6 inches of height and reduces the corner-to-corner diagonal, which matters when tilting through the landing turn. Most sofa legs unscrew by hand or with a wrench. Wrap the attachment points so hardware doesn't scratch the stairwell walls.
If your stairs have a 90-degree or 180-degree landing with less than 40 inches of depth, professional movers are recommended. They have furniture straps, shoulder dollies, and experience pivoting at tight landings. For straight flights, two strong adults can usually handle a standard 3-seat sofa.
