If you intend to install a wheelchair ramp in your doorway, you may consider how long the ramp slope should be. Some people believe that a relatively short ramp is preferable because that occupies a smaller area and may be less expensive. However, if you add a ramp that is excessively limited for the rise of the doorway being ramped, it may be both hard to operate and a disaster waiting to happen. This frequently results in a highly steep ramp that looks like a ski jump!
Choosing the ideal ramp for your usage may appear difficult, but the EZ-ACCESS Incline Calculator can assist. When you use the tool, it will calculate the ramp length you require predicated on your rise and ADA ramp slope prerequisites.

How To Calculate Ramp Slope Length?
The steps below will provide you with the appropriate length for a wheelchair ramp to meet your needs:
Take the following measurements.
- The total vertical rise you’re attempting to overcome
- Straight out from the highest point, the available distance without obstruction.
- The area’s total usable width
ADA Standards:
Understanding the ADA Requirements will help you understand the figures produced by the Mobility Ramp Calculator.
Recommendations for Ramp Length
Only commercial buildings with PERMANENT ramps are subject to ADA requirements.
The guidelines that follow are general recommendations for residential.
Unoccupied Residential Use:
When no one is sitting in a wheelchair or scooter as it climbs the ramp at home, a 3:12 slope is often recommended, which means that every 3″ of vertical rise necessitates at least 1′ (12″) of ramp length (14.5 degrees of incline).
For instance, a 24″ rise necessitates a minimum ramp length of 8′ (96″). (24 divided by 3).
Residential Occupied Use:
A 24″ rise, for example, necessitates a minimum ramp length of 12′ (144″). (24 divided by 2).
Commercial Inhabited Use: The ADA recommends a 1:12 slope for commercial use when someone is sitting in a wheelchair or scooter while it climbs the ramp, which means that every 1″ of vertical rise requires at least 1′ (12″) of ramp length (5 degrees of incline).
A 24″ rise, for example, necessitates a minimum ramp length of 24′ (288″). (24 divided by 1).
A shorter ramp is sometimes more practical. A 1:8 slope is recommended in this case, which means that every 1.5″ of vertical rise necessitates at least 1′ of the ramp.
For example, a 24″ rise necessitates a minimum ramp length of 16′. (24 divided by 1.5)
