The least possible slope shall be used for any ramp. The maximum slope of a ramp in new construction shall be 1:12. The maximum rise for any run shall be 30 in (760 mm).

The ADA Standards do not require that curb ramps have side flares, but limit the slope (1:10 maximum) where they are provided. Side flares are advisable where pedestrian traffic may cross runs to prevent tripping hazards.

Aug 1, 2024 · The ADA defines a ramp as a walking surface that has a slope greater than 1:20. This specific definition is what sets ramps apart from normal inclines. Installing ADA-compliant ramps serves people who use wheelchairs, walkers, or other mobility aids.

Jan 8, 2024 · Max Slope for ADA ramp: What is the maximum gradient for a wheelchair ramp? The ramp must have a 1:12 slope ratio. This means that there must be a one-inch rise in the ramp for every corresponding 12 inches of the ramp.

In the U.S. per the US ADA (Americans with Disabilities Act), a ramp is a sloping route constructed with a slope greater than 1:20 (one inch of vertical rise for every 20 inches of horizontal length, or run) and must conform to the standard ADA specifications for ramps.

The ADA requires that all business and public use wheelchair ramps adhere to a 1:12 slope ratio, meaning that for every inch of vertical rise there must be 12 horizontal inches (one foot) of ramp. If, for example, you had a stairway with a vertical rise of 21″, you would need 21′ of ramp.

This tool helps you determine whether a ramp meets the Americans with Disabilities Act (ADA) slope requirements. Simply enter the rise and run of your ramp to calculate the slope ratio and see if it’s compliant with ADA standards.

Mar 10, 2024 · According to ADA requirements, the cross slope of a wheelchair ramp may not exceed 2%, or 1:50. This measurement, which often applies to curb ramps, helps ensure the surface is level enough to keep mobility aids from tipping sideways.

According to the ADA, the maximum slope of a newly constructed ramp is 1:12 pitch, with every inch of a vertical rise requiring at least 1 foot of ramp length. This equates to a slope of about 4.8 degrees of incline.

Ramp runs shall have a running slope not steeper than 1:12. EXCEPTION: In existing sites, buildings, and facilities, ramps shall be permitted to have running slopes steeper than 1:12 complying with Table 405.2 where such slopes are necessary due to space limitations.
