Between what heights must all accessible wall-mounted controls be located for a forward reach?

The correct range for wall-mounted controls accessible for a forward reach is between 15 inches and 44 inches above the finished floor (AFF). This standard is based on design guidelines, such as those outlined in the Americans with Disabilities Act (ADA) and other accessibility standards, which aim to ensure that controls are within reach for individuals who may be wheelchair users or have limited mobility.

The range ensures that the controls can be easily reached while seated, which is critical for providing accessibility in various environments such as public buildings, workplaces, and residential spaces. Being between these specified heights accommodates a broad range of users, allowing for both functional use and independence.

The other options do not align with the established accessibility guidelines, as they indicate heights that would either be too low or too high, making them less practical for users who require accessible design features.
