How to Measure for a Ramp Wheelchair & Scooter

Calculations apply not only to walkers, manual wheelchairs, power wheelchairs and scooters, but also to individuals that may have impaired walking due to injury, amputation, surgery, or balance issues.

The incline chart below will help calculate the length of ramp needed for most situations and settings. However, keep in mind the ADA recommends a 3:12 slope which means for every 3" of vertical rise you are required to have at least one foot of ramp (14.5 incline). And this is for loading unoccupied wheelchairs/scooters (unoccupied means nobody is sitting in the wheelchair/scooter while it navigates up the ramp).

Consult your equipment's owner guide to see what degree of incline is recommended. A typical Power Wheelchair recommended incline capability is about 9.5 with the patient in the chair or scooter and about 14.5 unloaded. Pushing a manual wheelchair can be difficult or easy depending on: ramp length + patient weight.

Easy calculation: Divide the rise in inches by 3. (24 inch rise requires an 8 foot ramp.)
