How long of a ramp should I buy?

Recommended Slope Angles:

• > 7-degree: Manual wheelchair users without assistance
• > 10-degree: Manual wheelchairs assisted
• • An able assistant to help those users unable to do it alone
  • OK for strong independent wheelchair users
• > 12-degree: Power wheelchairs or scooters and assisted manual chairs
• > 15-degree: Restricted space, Unoccupied loading/unloading

Determining Ramp Length:

Use your desired slope. Measure total rise (how many inches from lower level to upper level)

• > 7-degree: Rise distance divided by 1.5
• > 10-degree: Rise distance divided by 2
• > 12-degree: Rise distance divided by 2.4
• > 15-degree: Rise distance divided by 3

Example: For a desired slope of 7 degrees with a rise of 12″ (1 foot), 12/1.5 = 8 foot ramp
