Scale height of figures in 1:60 and 1:72 scale. Historically the size of miniatures was described in absolute scale in various different systems of measurement, most commonly in metric and English units. A 28mm miniature means that the size of the miniature will be 28mm from the feet of the mini to the chosen reference point.
