A standard washer is 27" wide and 150–180 lbs. Most 36" stairways handle it — but use a dolly and bring a helper.
Whether it fits depends on measurements most people get wrong.
Washer width (27") + clearance (2") = 29" minimum clear stair width.
Item: Standard washer: 27"W × 27–31"D × 36"H (150–250 lbs). Compact: 24"W.
Space: Standard stairs: 36"W (31" clear). Fits with room to spare.
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

“Wish I'd used this before trying to force a fridge up the stairs.” — Lesson learned
Measurements verified by the ItemFits engineering team · Our methodology
Standard sizes say it works — but your measurements are what matter.
A standard 27" washer needs 29"+ clear width on the stairs. Standard 36" stairways (31" clear after rails) handle washers easily. Compact 24" washers fit even tighter stairways.
Use an appliance dolly with stair treads. Strap the washer to the dolly, tilt back 45°, and bump up one step at a time. Two people: one tilts, one guides. For front-loaders, reinstall shipping bolts first.
