What is the ADA-compliant rise to run ratio for ramps?

The Americans with Disabilities Act (ADA) specifies guidelines for accessible design, including the construction of ramps. The correct rise to run ratio for ramps according to ADA standards is 1:12. This means that for every one inch of vertical rise, there should be at least twelve inches of ramp run. This ratio is crucial for ensuring that ramps are not too steep, making them safe and usable for individuals with different types of mobility impairments.

Ramp design employing a 1:12 ratio allows for better stability and balance, reducing the risk of falls. It's particularly important in public buildings and spaces to ensure compliance with accessibility standards, providing equal access for all individuals, including those with disabilities.
