1 Maximum slope for hand-propelled wheelchair ramps should be 1 of rise to every 12 of length (4.8 degree angle; 8.3% grade). 2  Maximum slope for power chairs should be 1.5 rise to 12 length (7.1 degree angle; 12.5% grade). 3  Minimum width should be 36 (inside rails) - (48 is ideal).earn the correct measurements of a properly constructed wheelchair ramp: 1  Maximum slope for hand-propelled wheelchair ramps should be 1 of rise to every 12 of length (4.8 degree angle; 8.3% grade).
1 For example, ADA construction standards mandate that the slope of any wheelchair access ramp must be no greater than one inch of rise for every 12 inches of run. 2  Therefore, if you need to reach a platform that is 30 inches in height, you must plan to build the ramp to be at least 30 feet long. You'll need to measure up from the ground to find how many inches the ramp must rise. 2  At a minimum, your ramp should be 36 inches wide between railings to accommodate a wheelchair. 3  To be on the safe side, you might want to make it at least 40 inches wide.
