The preferred slope for a building access ramp is 1:12 or 1 inch of rise per 12 inches of horizontal run – that’s roughly an 8% slope also written as a 4.8 degree angle slope.

How long of a ramp do I need for 4 steps?

For commercial occupied use, the Americans with Disabilities Act (ADA) recommends a 1:12 slope. This means that every 1” of the vertical rise needs at least 1′ (12”) of ramp length. This equates to 5 degrees of incline.
