Stair Flooring Calculator
Estimate square footage for stair treads and risers using stair count, tread depth, riser height, and stair width.
Flooring type: Stairs: carpet, runners, hard surface treads, risers, and stair material planning
Estimate square footage for stair treads and risers using stair count, tread depth, riser height, and stair width.
Estimated stair flooring
This covers tread and riser face area only. Landings, stair noses, returns, runners, and product-specific stair parts can change the final material order.

Frequently Asked Questions
Does this include stair landings?
No. Measure landings separately as small rooms and add them to the project square footage.
Can I use regular flooring planks on stairs?
Some products allow it with approved stair noses or caps. Always check the manufacturer's stair installation requirements.
Why are stair estimates different from room estimates?
Stairs include separate tread and riser surfaces, extra cuts, and often special trim pieces, so square footage alone is not the full order.
