Wheelchair Measuring Guide
Wheelchair Measurements:
- Hip Width:
Use this to figure seat width if it is the widest point. - Widest Point:
Measure the widest area across the lower extremities if different from the hip width. This may influence seat width or arm style. - Chest Width:
Measure the widest point of the thorax just below the armpit. This measurement may influence system width or back width. - Heel to Knee:
Use this for legrest extensions and seat height. - SRP to Knee (Seat Reference Point to Knee):
This will determine the seat depth. - Elbow to SRP (Elbow to Seat Reference Point):
Measure this width with the arm in a 90-degree angle at the elbow and the shoulder in a neutral position. - Shoulder Height:
This will determine the height and the style of the back panel or the start for a custom back. - Head Height:
This will help determine the proper headrest height.
