Your ramp can not be any shorter than this length, but it can be longer. Decide whether you want to build a switchback, L-shape or U-shape ramp. Mark the length and width of the area where the ramp will be constructed with snap chalk. The wheelchair ramp must be a minimum of 36 inches in width.Constructing a ramp that is between 40 and 45 inches will ensure that there is enough room for the wheelchair to maneuver easily. Mark the chalk line where each post hole will be placed. There should be a post on each end of the wheelchair ramp.ut the posts to the desired length for the ramp. Each post must be 24 inches from the ground to the bottom of the ramp, and 36 inches from the ramp floor up. Each post will be a different length. They should be put in a row from shortest to longest.
