How stair is calculated
Lay out a straight staircase from floor-to-floor rise and available horizontal run. It computes integer risers, actual riser height, approximate tread depth, and pitch; verify headroom, landing, handrail, and local building-code rules before building. A 108-inch rise divided into 15 risers gives 7.2-inch risers. The calculation validates each input and keeps its stated units explicit. No. Stair geometry, landings, headroom, guards, and permitted tolerances vary by jurisdiction. This is an estimate for the stated assumptions; confirm measurements and any applicable professional or local standards before relying on it.
Stair Calculator is calculated from the supplied measurement fields using the units shown.A 108-inch rise divided into 15 risers gives 7.2-inch risers.
Assumptions & useful context
The result depends on the values you enter and the method described above. Displayed numbers may be rounded; calculations use the unrounded values. Check that this model matches your situation before relying on it.
Frequently asked questions
Does this guarantee code compliance?
No. Stair geometry, landings, headroom, guards, and permitted tolerances vary by jurisdiction.
Why round to a whole riser count?
A stair needs a whole number of equal risers; the calculator recalculates their actual height.
