How the calculation works

Number of Steps Calculator

n = max(1; round to nearest(Vertical rise / Target riser height)); Riser height = Vertical rise / n

Before 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
