What is the maximum recommended gradient for a portable wheelchair ramp?

Most portable ramps top out at a 1 in 6 gradient, though 1 in 8 is recommended for comfort and safety wherever there is enough space.

Permanent installed ramps follow stricter building guidance of around 1 in 15, but that is rarely practical for a portable ramp used at a doorway or kerb.
