How to Calculate the Appropriate Wheelchair Ramp Length

Choosing the correct ramp length when it’s time to improve your property for better access can be a challenging task. A too-short ramp creates a sharp slope that not only requires more work to navigate properly but also puts you at risk of damage if you fall. Ramps that are too long for the step or steps will reduce the slope’s steepness, making them safer and simpler to use than shorter ramps. However, if the ramp is longer than necessary, it may require more room that isn’t possible at your site.

We’ve compiled a full guide to understanding the needed calculations and designed a mobility ramp to help you determine the safest ramp length for your area and steep climb.

Understanding the Crucial Parameters of Wheelchair Ramp

Vertical Rise: The overall height you’d want to climb. If there are many steps, combine their heights together to get the overall vertical increase in inches.

Available Space: The amount of space you have to work with. Begin your measurement at the top of the tallest step, where the ramp’s top will be located, and then stretch straight out as long as you can until you come across an obstruction. This is a crucial parameter for entryways with curves or other barriers since it may restrict the length of your ramp.

Total Usable Width: Measure the width of your doorway, particularly the region where a wheelchair, mobility scooter, or other mobility equipment will need to pass through. To guarantee safe passage, a minimum of 30″ or 36″ is recommended, however, it may be less in older structures.

Ramp Length: Because threshold ramps are shorter, they are measured in inches, whereas wheelchair ramps and modular ramps are measured in feet. The slope of the ramp in various usage situations is specified by the ADA, and this determines the length of the ramp required.

The most often suggested slope for wheelchair ramps is a Commercial Occupied Use ratio of 1:12, however, the slope can be reduced to suit older structures and narrower areas.

The 1:12 slope calculation shows that every inch of vertical rise necessitates a ramp length of at least one foot (12″). A slope of around 5 degrees is created as a result of this.

Choosing the Right Wheelchair Ramp

Door Entry Ramps / Threshold Ramps

Threshold ramps, which are typically available in lengths up to 2′, are ideal for navigating wheelchairs, powerchairs, and mobility scooters over small climbs, uneven floors, or through entrances where the bottom plate makes a difficult barrier.

Portable Ramps for Wheelchairs

Portable wheelchair ramps are available in sizes ranging from 2′ to 12′ for bigger climbs or several steps. Consider if you want a foldable ramp for easy mobility or one with mounting holes to keep it firmly attached to the top step.

Ramps for Wheelchairs that are Modular

These modular ramp systems are often more intensive to build and need the use of platforms to break up the long ramp lengths for ADA compliance. They are available in big sizes up to 30′ and different configurations including L-turns and U-turns.
