- 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 arm pit. 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.
