Portable Wheelchair Ramps

As a general rule most ramp manufacturers recommend a gradient no steeper than 1:12 for independent use and 1:10 for assisted use.

A simple calculation for finding out ramp lengths is to multiple the height by the ratio.

i.e. if working on a 1:12 ratio multiply the height of step by 12 to give you the minimum length of ramp.

6″ step x 12 = 72″ (6ft ramp)
