What is the maximum reach of a person using a wheelchair?

The maximum reach of a person using a wheelchair is typically considered to fall within the range of 400 mm to 1550 mm. This range is based on ergonomic and accessibility guidelines that take into account the average physical capabilities of wheelchair users. The lower limit of 400 mm reflects the distance from the front of the wheelchair that can be reached comfortably and safely. The upper limit of 1550 mm indicates the maximum height to which a person in a wheelchair can extend their reach, allowing for access to various surfaces and fixtures in their environment.

By defining this range, building codes and accessibility standards can ensure that spaces are designed to accommodate individuals with mobility challenges, allowing them to interact with their surroundings effectively. This includes considerations for reaching light switches, countertops, shelving, and other fixtures that are essential for daily living and independence.
