# How Long Should My Wheelchair Or Scooter Ramp Be?

What else should I consider when purchasing a wheelchair or scooter ramp?

To use this chart to determine the proper incline for a wheelchair or scooter ramp there are a few steps that should be done beforehand:

1. Determine the incline your wheelchair or scooter is designed to climb
2. Measure the distance from the top step or landing to the ground. That distance is called the rise.

Once that measurement for the rise has been made, refer to the ramp incline chart to find the proper ramp length. For example, if someone was interested in a 3 wheelchair or scooter ramp and rise was 9″, then the incline would be 14.5° The ADA has suggested that a slope of 1:12 the best suited for wheelchair or scooter ramps. That means for every inch of rising the wheelchair or scooter ramp extends 12 inches or one foot. That means the ideal wheelchair or scooter ramp incline in degrees would be 4.8° Once the wheelchair or scooter ramp is installed, make sure that the wheelchair or scooter ramp is used only with a qualified helper.
