# How To Plan Right Ramp Slope Length For Wheelchair Ramps.

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

## 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)
