The head height is measured from the bottom of the chin to the top of the head.
The top of the head is defined differently for each country:
- It is the crown is where the skull would be if it was visible (excluding hair).
- or it is the top of the hair.
The head height can be changed and decimal numbers are allowed.
The decimal value is separated by a "." from the whole number, eg: 2.37
If pixel values are entered, than only whole numbers are allowed.
The head height must lie between an allowed minimum and maximum range.
