Stairs
Stringer Length Calculator
Your measurements : vertical rise, horizontal run. Your estimate : length.
How the calculation works
Stringer Length Calculator
√(Vertical rise² + Horizontal run²)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 m
- Horizontal run
- 4 m
Length 4.47 m
