Seat height in mm, loaded seat. Grey bars: the range each EN 1335-1:2020 Type must cover. Black bars: the manufacturer’s published range.

Using the popliteal-height ratio of 0.255 × stature and a 25 mm shoe allowance (Pheasant and Haslegrave, Bodyspace; see the height calculator), this range puts the thighs roughly level for people about 155–198 cm tall. That is an estimate from average body proportions, not a fitting.
