ADA Clearance Checker

Check doors, routes, turning space, clear floor space, thresholds, and ramps against the most common 2010 ADA Standards clearances — with instant pass / fail badges for each.

Based on the 2010 ADA Standards for Accessible Design. Also verify ICC/ANSI A117.1 and your local code, since amendments vary — confirm requirements with your building official or accessibility consultant.

Common ADA Clearance Requirements

The 2010 ADA Standards set minimum clearances that make spaces usable by people who use wheelchairs and other mobility devices. Doorways need at least 32 inches of clear width measured with the door open 90 degrees, accessible routes need 36 inches, and a wheelchair turning space needs a 60-inch circle or a 60-by-60-inch T-shaped space.

A clear floor space for a stationary wheelchair is 30 by 48 inches, thresholds at doorways are limited to 1/2 inch high (beveled), and ramps may not exceed a 1:12 running slope — one inch of rise for every twelve inches of run. This checker covers those high-frequency items; full compliance involves many more provisions for reach ranges, restrooms, and signage.

Frequently Asked Questions

What is the minimum ADA door width?

An accessible doorway must provide at least 32 inches of clear width, measured from the face of the door to the stop with the door open 90 degrees. Doors in a series and other conditions can require more.

What is the ADA turning radius?

A wheelchair turning space must be either a 60-inch diameter circle or a 60-by-60-inch T-shaped space, allowing a person using a wheelchair to make a 180-degree turn.

What is the maximum ADA ramp slope?

The maximum running slope for a ramp is 1:12, meaning one inch of vertical rise for every twelve inches of horizontal run. Ramps also need level landings and, in most cases, handrails.
