Wheelchair Measuring Guide

Wheelchair Measurements:

1. Hip Width:
   Use this to figure seat width if it is the widest point.
2. Widest Point:
   Measure the widest area across the lower extremities if different from the hip width. This may influence seat width or arm style.
3. Chest Width:
   Measure the widest point of the thorax just below the arm pit. This measurement may influence system width or back width.
4. Heel to Knee:
   Use this for legrest extensions and seat height.
5. SRP to Knee (Seat Reference Point to Knee):
   This will determine the seat depth.
6. 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.
7. Shoulder Height:
   This will determine the height and the style of the back panel or the start for a custom back.
8. Head Height:
   This will help determine the proper headrest height.
