Stairs
Number of Steps Calculator
Your measurements : vertical rise, target riser height. Your estimate : risers, riser height.
How the calculation works
Number of Steps Calculator
n = max(1; round to nearest(Vertical rise / Target riser height)); Riser height = Vertical rise / nBefore you order
- A straight flight is assumed. The upper floor is the final landing, so there is one fewer tread than riser. No headroom, landing, handrail or local code validation is included.
- Planning estimate only. This is not a structural design, a safety approval or a local code check.
Worked example
- Vertical rise
- 2.8 m
- Target riser height
- 0.175 m
Risers 16
Riser height 0.18 m
