Stairs
Stair Calculator
Your measurements : vertical rise, horizontal run, number of risers. Your estimate : risers, treads, riser height.
How the calculation works
Stair Calculator
Riser height = Vertical rise / n; Tread depth = Horizontal run / (n − 1); n = Number of risersBefore 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
- Horizontal run
- 3.6 m
- Number of risers
- 16
Risers 16
Treads 15
