Standard stairs are 36 inches wide — but handrails reduce clear width to 31 inches.How Wide Do Stairs Need to Be for a Mattress?Find the minimum stair width for a mattress. Mattresses flex and stand on edge — even king mattresses fit most standard stairways.How Wide Do Stairs Need to Be for a Refrigerator?Find the minimum stair width for moving a fridge. Fridges are rigid and heavy (200–350 lbs) — width and weight are both challenges.How Wide Do Stairs Need to Be for a Piano?Find the minimum stair width for a piano. Upright pianos are 24 inches deep — but at 400–800 lbs, the width is less of a problem than the weight.How Wide Do Stairs Need to Be for a Washer?Find the minimum stair width for a washing machine. Standard washers are 27 inches wide — most stairs handle them with proper equipment.How Wide Do Stairs Need to Be for a Dresser?Find the minimum stair width for a dresser. Dressers go depth-first (16–20 inches) and fit most stairs easily. Weight is manageable with drawers removed.

What to Measure

1Stairway width — measure wall-to-wall, or wall-to-railing if a railing is present.
2Ceiling height above stairs — measure the vertical clearance at the lowest point along the stairway.
3Landing dimensions — measure the length and width of any mid-stair landings and the top/bottom landings.
4Turn angle — identify whether your stairs have a 90° L-turn, a 180° U-turn, or a straight run.

Common Mistakes to Avoid

Only measuring the stair width and ignoring the ceiling clearance above the stairs.
Forgetting that landings and turns are the real bottleneck — the straight run is rarely the problem.
Not accounting for the railing, which reduces usable width by 3–4 inches.
Assuming a long item can simply be tilted — the stairway angle limits how much you can tilt.

Frequently Asked Questions

What is the minimum stairway width for moving furniture?

Building codes require a minimum clear width of 36 inches, and most residential stairs are 36–42 inches wide. Subtract 3–4 inches if a railing is present on one side.

How do I navigate a 90-degree stair turn with a large item?

Tilt the item upright and use the vertical space above the landing to clear the turn. Having one person above and one below helps control the angle as you pivot around the corner.

Can I remove the railing temporarily?

In most cases, yes — removing a railing gains 3–4 inches of usable width. Railings are typically attached with brackets or screws and can be reinstalled afterward.

Is it harder to move furniture up stairs or down stairs?

Going up is physically harder due to gravity and the lifting angle. Going down requires more control since the weight pulls forward. Both directions have the same clearance constraints.

Do spiral stairs have different clearance rules?

Yes — spiral stairs have a much tighter inner radius than outer radius. Always measure clearance at the narrowest point near the center pole, and expect significant width limitations.
