ADA guidelines mandate a 1:12 ratio of rise to run for wheelchair ramps. How long (horizontally) would a ramp need to extend to elevate a person from a height of 2 feet to a height of 6 feet? If a ramp extends 30 feet horizontally, what is the maximum increase in elevation that it could result in?

If the slope of a ramp is between 1:12 and 1:16, the maximum rise shall be 30 inches (760 mm) and the maximum horizontal run shall be 30 feet (9 m). If the slope of the ramp is between 1:16 and 1:20, the maximum rise shall be 30 inches (760 mm) and the maximum horizontal run shall be 40 feet (12 m). Hope this helps?
