Frequently Asked Questions (FAQs)

1. What is the purpose of this wheelchair ramp slope calculator?

This tool helps you determine the correct slope for a wheelchair ramp to ensure it is compliant with accessibility standards. It calculates the ramp slope percentage based on your input values for rise (height) and run (length), providing recommendations for different regulations.

 

To use the calculator, simply enter the rise (height) and run (length) of the ramp, select your preferred measurement unit (cm, in, or ft), and click “Check Compliance.” The tool will display the ramp slope, compliance with various standards, and recommended ramp lengths for different regulations.

 

You need to enter the rise (the vertical height from the base to the top of the ramp) and the run (the horizontal length of the ramp). The tool will then calculate the slope based on these values.

 

The calculator compares the ramp slope with several common standards, including:

  • ADA (Americans with Disabilities Act) – 1:12 ratio (8.33% max slope)

  • ISO 21542 – 1:12 ratio (8.33% max slope)

  • UK Building Regulations – 1:12 ratio (8.33% max slope)

  • AS 1428.1 (Australia) – 1:14 ratio (7.14% max slope)

  • Saudi SBC – 1:12 ratio (8.33% max slope)

  • Portable Use Maximum – 1:6 ratio (16.7% max slope)

Complying with accessibility standards ensures that wheelchair ramps are safe and accessible for individuals with mobility challenges. It helps prevent accidents, provides comfort, and guarantees that the ramp is usable in various environments.

 

If your ramp does not meet the required slope for compliance, consider increasing the length of the ramp (the run) or lowering the height (the rise). Longer ramps with a gentler slope are safer and easier to use.
