Staircase steps calculator

Enter the total height to climb: get the number of steps, the recommended riser and tread.

Total height to climb (cm)

How it works

We aim for a comfortable riser around 17-18 cm: the number of steps is the total height divided by this value. The tread comes from the «step rule» (2×riser + tread ≈ 63 cm).

Note

This is a rough estimate: for code-compliant stairs check local regulations and, for structural work, a professional.
