However, stricter restrictions on the maximum rise apply: Remember that the ADA prohibits slopes steeper than 1:8. For a ramp the maximum running slope allowed is 8.33% (8.33% is a 1:12 slope). As the heights require greater efforts, the slopes begin to reduce to reach recommendable values of 8%for heights of up to 50 centimeters; 6%for heights of up to 100 centimeters; 5%for heights of up to 150 centimeters; and 4% for ramps being used by the elderly.
