Ramp Widths

Dimensioned drawing measuring the minimum widths and clearances of an ADA ramp

ADA accessible ramps must maintain a minimum clear width of 36” | 91.4 cm at all times. The cross slope along the width of any ramp must be less than 1:50 | < 2%. The 36” | 91.4 cm clear width must be maintained between all including handrails. Ramp surfaces should constructed as slip-resistant, stable, and firm systems.
