The Uniform Federal Accessibility Standards (UFAS) specify that the maximum slope for wheelchair ramps should be 1:12, which translates to a rise of 1 inch for every 12 inches of run. This means that for every inch of height the ramp rises, it should extend at least 12 inches horizontally.
If you were mentioning an angle, the equivalent rise over run for a ramp that is within this guideline is approximately 4.76 degrees. However, if you're specifically considering the maximum rise of 4.78 inches, that would not be in line with the 1:12 ratio since that would imply the total length of the ramp must be at least 57.36 inches (4.78 inches multiplied by 12).
To clarify, what is critical is that the ramp complies with the guidelines of a 1:12 slope. If you have specific circumstances or examples you’d like to discuss, feel free to provide them!
