Ramp Slope Calculator
Result
Ramp Slope Calculator Calculate ramp slope, angle, run length, and ADA compliance for wheelchair ramps. — free online calculator.
Formula
- Ramp Slope Calculator calculates its result from Rise (height), Run (horizontal distance). It uses the formula Slope% = rise/run × 100; Angle = atan(rise/run); ADA max: 1:12 (8.33%). Change any input to recalculate the result instantly.
- The main inputs are Rise, Run (horizontal distance). 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: Ramp Slope
- Rise: 12 height
- Run (horizontal distance): 144
Using Rise (height) = 12, Run (horizontal distance) = 144, the calculated result is 12.
