Wheelchair Measurement Guide
Measure from the back of the rear-end to the inside of the knee, minus at least two inches. Some people prefer more overhand to make room for the hand when lifting the knee.
Determines how far the toes extend away from the body, measured from the horizontal. Keeping the toes closer to the wheelchair allows you to turn in a tighter space. This depends, in part, on the ability of the knee to bend.
Front Seat to Floor3
Measure the leg from the back of the knee to the sole of the foot. Then subtract the compressed thickness of any cushion(s) used. Next add a minimum of two inches for footrest clearance, unless the wheelchair will be foot propelled.
Determined by the widest point of the body at the hip, plus an inch to ensure room to move. Consider bulk of clothing, particularly a heavy coat.
Measured from the seat base, to the top of the wheelchair back. Depends on how much upper back support is needed, and also affects freedom of the upper body to rotate.
