Wheelchair Ramp Buying Guide
To Determine the Ramp Length Needed:
- Measure the rise in inches vertically from ground level to the top step or landing where the ramp will sit.
- Find the maximum ramp incline based on the ramp length requirements below.
- Using the Ramp Incline Chart, determine the ramp length based on the desired ramp incline.
- Find a PVI ramp that meets your needs with our PVI Ramp Model Selection Guide (pdf).
Ramp Length Requirements
To meet ADA requirements, the incline must not exceed a 1:12 slope (12 inches of ramp length for every 1 inch in rise).
For ramps that do not need to meet ADA requirements, Prairie View Industries recommends no greater than a 2:12 slope (9.5 degrees) for most applications. To find a 2:12 slope, find the rise in inches and divide by 2. The resulting number is the length of the ramp that is required in feet.
Example: If the rise is 12 inches high, the ramp length needs to be 6 feet for a 2:12 slope.

Tips for Using a Wheelchair Ramp
- Never exceed a slope greater than 2:12 for an occupied scooter or wheelchair.
- Never exceed a slope greater than 3:12 for an unoccupied scooter or wheelchair.
- Always make sure a qualified assistant is present when using any portable ramp.
- Always make sure that the top of the ramp is secured on the step or landing before using the ramp. The top of the ramp may need to be anchored to the landing surface using the steel security pins provided.
- Always make sure there is adequate head clearance before attempting to load an occupied scooter or wheelchair into a vehicle.
- Always read and follow the manufacturer's recommendations for your wheelchair or scooter.
- Always secure your lap belt before using a portable ramp.
- Watch the included safety DVD prior to using your portable ramp.
Slope Recommendations1:12 Slope (4.8 degrees)
- Recommended by the ADA for home and commercial ramps up to 30 feet long
- Allows most strong manual chair users to use the ramp unassisted, although PVI always recommends assistance when using a portable ramp
- Maximum recommended slope for portable ramp use by occupied wheelchairs and scooters with a qualified assistant
- Maximum recommended slope for loading unoccupied wheelchairs and scooters
