What is the recommended gradient for wheelchair ramps in the UK?

We quite often receive requests for wheelchair ramps from people who don’t really know how long the ramp should be.

Recommended gradient for portable wheelchair ramps in the UK?

As a general rule when using portable wheelchair ramps most ramp manufacturers recommend a gradient no steeper than 1:12 for independent use and 1:8 for assisted use over shorter distances.

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

i.e. if working on a 1:8 ratio multiply the height of step by 8 to give you the minimum length of ramp.
