To determine seat height for a wheelchair, which measurement is taken?

• A. From user's heel to popliteal fold
• B. From shoulder to hip
• C. From ankle to knee
• D. From hip to knee

Answer: (A)

Seat height is set by the length of the lower leg when the knee is bent about 90 degrees, so the measurement taken is from the floor at the heel up to the popliteal fold (the back of the knee). This distance directly tells you how high the seat needs to be to allow the feet to rest comfortably on footrests or the floor while the knee is in a functional position. Other measurements like shoulder-to-hip, ankle-to-knee, or hip-to-knee don’t directly inform seat height because they don’t reflect how tall the seat surface needs to be to accommodate the leg length and foot placement.
