How Steep Should Wheelchair Ramps Be*

1:6 (10°)** - Acceptable in some cases for short threshold ramps.

1:8 (8°)** - A useful balance between gradient and space, suitable for portable ramps in some assisted applications and events, etc.

1:12 (5°) - Often required by social services/local authorities. Minimum required by Part M of building regs for installed ramps.

1:15 (4°) - Sometimes required by social services/local authorities for independent access.

To create a 1:12 gradient
Select height of step:

Recommended gradient for wheelchair ramps.

With regards to Part M of the building regulations the slope of a fixed ramp is dependent on the height of the step,

A 500mm high step should have maximun gradient of 1:20, a 333mm high step should have maximun gradient of 1:15 and a 166mm high step should have maximun gradient of 1:12. For goings between 2m and 10m it is acceptable to use a sliding scale.
i.e. 1:13 for 3m, 1:14 for 4m, 1:16 for 6m, etc.
Wheelchair Ramps Gradient calculator

Our wheelchair ramp slope calculator is devised for portable wheelchair ramps and is based on a 1:8 gradient, ensure this suits your requirements before selecting your ramp and that the ramp you choose does not create a slope that is too steep for independent wheelchair users.

Futher information about fixed ramps and building regulations on ramps can be found on our page at - Wheelchair Ramp Regulations and Guidance

* - As recommended by leading UK Ramp Manufacturer
** - Wheelchairs must descend backwards - Assess safety/risk
