What is the minimum width for both toe clearance and knee clearance?

1. 17 inches

2. 25 inches

3. 27 inches

4. 30 inches

The correct answer is: 30 inches

The minimum width for both toe clearance and knee clearance being set at 30 inches is consistent with accessibility standards, specifically those put forth by the Americans with Disabilities Act (ADA) and similar building codes. This dimension is important because it ensures adequate space for individuals using wheelchairs or other mobility devices to maneuver safely and comfortably. Toe clearance allows for proper foot positioning without obstruction, while knee clearance facilitates easy approachability and use of fixtures or furniture at accessible heights. Maintaining a minimum width of 30 inches for these clearances helps in providing accessibility and usability for all individuals, promoting inclusivity in design. In contrast, smaller dimensions would not allow sufficient room for maneuverability or accessibility, potentially creating barriers for users with mobility impairments. Thus, 30 inches is established as a standard to promote safety and accessibility in built environments.
