Measurements Needed

Choose the incline based on your equipment’s user guide. The ADA standard ratio is 1:12, but please check with your local city code.

Based on the standard incline, you need to know the rise of you steps for your ADA ramp calculator. Just measure the distance from the floor to your top step in inches.

Ramp Calculations

According to ADA standard, you’ll need a ramp of 1 foot per inch of rise height. For example, if your rise is 20 inches, your ramp length is 20 feet.

Depending on the specifications of your equipment you can use other ratios.

The formula behind this second calculation is:

Total height in inches / inches of rise per foot

For example, if you need a ramp to go up 2 feet and have a ratio of 3:12, it would be 24 / 3 = 8 feet long

Installing a wheelchair ramp costs between $935 to $2,915, depending on your specs. Contact your local wheelchair ramp builder for professional installation.
