You may have also 45mm, 75mm, 80mm, 90mm, 105mm, 115mm, 120mm, 130 and 135mm, 140mm, 160mm
I have constituted several Power Point files wigh pictures of flats per size families, so I have these measures in mind (several thousand flats).
However the size is not always defined on the same manner.
The 'size' is usually defined as the distance of a character from the foot to the eye level.
But it is also given as total height Total height, of the character, or total height of a bust, or total height of a group of people, from lowest point to highest point.
One example= if the character is sitting, it would not be the 'extended size of the person supposely upright, ( eyes to foot), but the total height of the scenery.
Some people on horse too are sometimes defined as total height, top head '(or helmet or hat), to floor, or by the size, = height of the human person from foot to eye. You might have a knight of horse sold as 130 mm total height, or 54mm size (of the person himself).
Busts could also be given is reduction fraction of a standard human body, like for figures (1/10, 1/16, .. equivalent to 200mm, ....).
(Also that flats made in the USA are not in mm but in inches or their fractions, and correlation to the metric system is even more complex).
