How to Find Proper Length for Wheelchair Ramp?

Wheelchair ramps create an easy platform to enter and exit houses, apartments, vehicles and decks. Before buying a wheelchair ramp, it is very important to know about its measuring terminologies and buy the one that best suits your requirements. Choosing a ramp with proper length may seem a difficult task to many. If the ramp is too short, its steep slope can become a reason for serious injuries. Choosing a longer ramp can pose a problem of space shortage. So a correctly measured ramp is very important for safe patient transfer across the ramp. To make the task of measuring ramp length easier, we bring to you a brief measuring guide for ramp length.

Terminologies Related To Wheelchair Ramps

  • Length - The specified length of a ramp or a section of a ramp.
  • Rise - The vertical distance from the ground to the top step or landing where you want the top of your ramp to be.
  • Slope - The inclination or steepness of the ramp. It shows the relationship between the rise and the length of the ramp. Typically, Americans With Disabilities Act (ADA) recommends 1:12 ratio or 5-degrees as the standard ramp slope for wheelchair. It means that for every 1 inch of rise, 12 inches of ramp is required.
     

 

Generally Recommended Wheelchair Ramp Slopes

  • 5-degrees (1:12) - ADA compliant for loading unoccupied wheelchairs or scooters. Recommended for public and commercial properties. 1 inch rise per 12 inch ramp length is equals to 5 degrees.
  • 7-degrees (1:8) - Recommended for manual wheelchairs with independent user or limited strength attendant.
  • 10-degrees - Recommended for manual wheelchairs with strong assistance.
  • 12-degrees - Recommended for manual wheelchairs with strong assistance, power wheelchairs, and scooters.
  • 15-degrees - Recommended for restricted space and unoccupied loading or unloading. Not practical for home use.

Factors Affecting Wheelchair Ramp Slope And Length

Inclination of a ramp and the associated length are based on the below-given factors:

  • Whether the user will operate the wheelchair on his own or will there be a companion to push it?
  • How much load is the wheelchair ramp supposed to bear?
  • What is the height of the step from where the ramp will start?
  • How much space is available to install the ramp?
  • How strong is the user or the person pushing the wheelchair?

Commonly Recommended Wheelchair Ramp Slopes

  • 5-degrees (1:12) - ADA compliant for use by unoccupied scooters and wheelchairs. Recommended for commercial and public properties. A slope of 5 degrees denotes 1 inch rise per 12 inch ramp length.
  • 7-degrees (1:8) - For manual wheelchairs with independent user or limited strength attendant.
  • 10-degrees - For manual wheelchairs with strong attendant.
  • 12-degrees - For manual wheelchairs with strong attendant, scooters, and power wheelchairs.
  • 15-degrees - For restricted or limited space and unoccupied loading or unloading. Not suitable for home use.

Wheelchair Ramp Length Calculator

According to your personal requirements, choose the ramp slope. Then measure the total rise from the upper level to the lower level and divide it by the slope. This will give you the ramp length. Standard measuring unit for rise is inches and for ramp length is foot.

  • 5-degrees - Divide rise distance by 1
  • 7-degrees - Divide rise distance by 1.5
  • 10-degrees - Divide rise distance by 2
  • 12-degrees - Divide rise distance by 2.4
  • 15-degrees - Divide rise distance by 3

For example - Given a rise of 12" (1 foot) and a required slope of 7 degrees, 12/1.5 = 8 foot ramp is required.
