It can be overwhelming to purchase a ramp. The length of your ramp is the first thing you need to decide. We'll show you how to calculate your ramp length in just three easy steps in this brief post.
In this article:
-
Step 1: Measure the rise
-
Step 2: Choose your slope based on use
-
Step 3: Find your ramp length using our easy guide
FIRST, CALCULATE YOUR RISE USING THE DIAGRAM BELOW AS A GUIDE
 |
Measure the rise from the door threshold or from the landing outside the door to the flat area that the other end of the ramp will rest on. Keep in mind that the ground may slope away from the bottom of the steps. (see diagram) |
NEXT, USING THE RISE, CALCULATE THE LENGTH OF RAMP NEEDED BASED ON HOW YOU WILL USE THE RAMP:
| Slope | Best Used For... | Calculate Ramp Length |
| 4.8 Degree | This is Americans With Disabilities Act (ADA) compliant | Rise distance divided by 1 |
| 7-degree | Manual wheelchair users who are independent or who have an attendant with limited strength | Rise distance divided by 1.5 |
| 10-degree | Manual wheelchairs with a reasonably strong attendant | Rise distance divided by 2 |
| 12-degree | Power wheelchairs or scooters and manual chairs with a strong attendant | Rise distance divided by 2.5 |
| 15-degree | Restricted space, unoccupied loading/unloading | Rise distance divided by 3 |
LAST, USING YOUR RISE AND YOUR CHOSEN SLOPE FROM ABOVE, USE THE TABLE BELOW TO FIND YOUR RAMP LENGTH:
