After measuring seat height from heel to popliteal fold, what is the typical allowance added?

Explanation:
When sizing seat height, you start with the distance from the heel to the popliteal fold to capture the leg length while seated. You then add an allowance for foot clearance and footwear. The typical addition is about two inches, which gives room for shoe heel height and ensures the feet can rest on the footrests without the foot dragging or forcing an awkward knee angle. Adding more (three or four inches) would raise the seat too high and disrupt knee and hip alignment, while too little (one inch) wouldn’t reliably account for shoes or foot clearance.
