Calculate wheelchair ramp measurements for ADA compliance. Enter your rise height to get required length, slope percentage, and angle instantly. Free tool with step-by-step guidance.
This calculator helps you determine the proper measurements for an accessible ramp based on ADA standards. Enter the desired rise (height) of your ramp, and the calculator will determine the required run (length) and slope.
According to ADA standards, the maximum slope for an accessible ramp is 1:12 (8.33% or 4.8°). This means for every inch of rise, you need 12 inches of run.
