The rules used
- Slope: 1 inch of rise for every 12 inches of ramp.
- At most 30 inches of rise in one run, then a level landing.
- Landings at least 60 inches long at the top and bottom of every run, and 60 by 60 inches where the ramp turns.
- Clear width at least 36 inches.
- Handrails on both sides when the rise is more than 6 inches, 34 to 38 inches high.
These are the ramp rules in the ADA standards (U.S. Access Board). They are written for public buildings; private homes don’t have to follow them, but builders use them because a steeper ramp is harder to push and less safe.
