To Establish the Proper Ramp Length:

Select the incline you desire. Refer to your equipment’s user guide or individuals capabilities. We start you off with the ADA Standard Ratio of 1:12, but we recommend you confirm with your local/city code.
Measure the distance from the top step/landing to the ground (RISE).
Enter the values in the form to determine your run and ramp length

CAUTION! At any incline, use ramp only with a qualified helper.
CAUTION! Refer to your equipment’s user guide for exact recommendations concerning acceptable usage and allowable slope.
Notice: If rise is greater than 30” a platform is required.

Take the incline calculator anywhere with the EZ-Access incline chart
