What is the minimum width required for knee clearance?

The minimum width required for knee clearance is 36 inches. This width is established to ensure accessibility and comfort for individuals using wheelchairs or other mobility devices. The specified dimension allows users sufficient space to maneuver and sit comfortably at surfaces like sinks, work tables, and counters, which is crucial for compliance with accessibility standards such as the Americans with Disabilities Act (ADA).

A width of 36 inches not only accommodates the knees but also provides enough room for individuals to approach and utilize the space without obstruction. This dimension is particularly important in public and commercial settings where the design must facilitate access for all users, thus promoting inclusivity and safety.
