Rise – the ramp cannot rise greater than 30 inches per run (a run is from base to top of a ramp) Running Slope – the running slope is the direction people travel when heading up or down the ramp run; the maximum slope is 1:12 (or one foot change in elevation every 12 feet of ramp) Pick the 1:16 option from a drop-down list. T he commercial and public facility standard for slope is 1:12 (in inches) or about 5 degrees of incline.

It's calculated from the tangent of the inclination angle: slope[%] = 100% * rise/run = 100% * tan(angle). Example: A 24" rise requires a minimum ramp length of 24’ (288") (24 divided by 1).
