Building code requires 36" stair width, but handrails reduce clear space to 31". See if your couch can make it — including landing turns.
Whether it fits depends on measurements most people get wrong.
Stair clear width (31" typical after rails) vs. sofa depth (32–36" on side). Landing length vs. sofa length (84–96").
Item: Standard sofa: 84"L × 36"D × 34"H. On side: 84"L × 34"H × 36"W.
Space: Standard stairs: 36"W (31" clear). Landing: typically 36"×36" to 42"×42".
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

Measurements verified by the ItemFits engineering team · Our methodology
Standard sizes say it works — but your measurements are what matter.
You need at least 28" of clear width (between handrails) for a standard sofa on its side. With a 36" wide staircase (31" clear after handrails), most sofas fit. The landing is usually the bottleneck, not the stair width.
Stand the sofa on end, slide it to the landing, then pivot it around the corner. For L-shaped stairs, you need landing depth ≥ sofa width (84"+) or enough ceiling height to tilt over the railing. U-turn landings are the hardest — often impossible for sofas over 84".
