Spiral Staircase Calculator
Result
Spiral Staircase Calculator Calculate number of steps, rotation per step, and tread width for a spiral staircase. — free online calculator.
Formula
- Spiral Staircase Calculator calculates its result from Total Rise, Riser Height, Walkradius. It uses the formula Steps = ⌈total rise / riser height⌉; Rotation = 360° / steps; Tread@walkline = 2π × walkRadius / steps. Change any input to recalculate the result instantly.
- The main inputs are Total Rise, Riser Height, Walkradius. Enter them in the units and format shown in the calculator.
- Keep measurements and project assumptions consistent before comparing or combining values.
- Changing any input above recalculates the result with the same calculation engine used by this page.
Example: Spiral Staircase
- Total Rise: 2
- Riser Height: 3
- Walkradius: 4
Using Total Rise = 2, Riser Height = 3, Walkradius = 4, the calculated result is 25.1327412287.
