1. Let the person sit on a flat surface2. Measure the vertical distance from the ground to the hollow at the back of the knee3. This measurement should not be less than the knee to heel dimension (KHL) + 4 cm to hallow sufficient footplate clearance above the ground4. Subtract any cushion tickness to give the seat height front (SHF) wheelchair measurement.
