Use this to figure seat width if it is the widest point
Measure the widest area across the lower extremities if different from the hip width. This may influence seat width or arm style.
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 leg rest 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.
This will determine the height and the style of the back panel or the start for a custom back.
This will help determine the proper headrest height.
