Ramp Widths

ADA accessible ramps must maintain are ramp surfaces that must maintain regulated dimensions and be constructed as slip-resistant, stable, and firm systems.

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 or <2%. The 36” (91.4 cm) clear width must be maintained between all including handrails.

What is the minimum clear width of an ADA accessible ramp?
The minimum clear width of a ramp is 36” | 91.4 cm.
What is the maximum cross slope of a ramp?
The maximum allowable cross sectional slope of a ramp must be less than 1:50 | < 2%.
How high are handrails along an ADA ramp?
Handrails along an ADA ramp must have a height between 34”-38” | 86.4-96.5 cm above the ramp surface. The minimum 36” | 91.4 cm clear width of a ramp must be maintained between handrails at all points.

Ramps are inclined surfaces that join different levels of a space. Commonly used at the entrances of buildings to accommodate level changes, ramps provide building access to wheelchair users. The maximum slope of a ramp is calculated to provide comfortable and easy access to the building.
