3.4 Vertex-tragion height

the vertical distance from the head of the vertex to the ear screen point

3.5 Vertex-pupil height

the vertical distance from the head of the vertex to the eye angle

3.6 Gnathion opisthocranion distance

4.1 Overview

The head-face dimensions of minors are calculated according to the actual measured head-face dimensions of Chinese 4~17 years old male and female.

This Standard includes 15 head-face dimensions of minors. See Annex A for measurement items.

4.2 Head-face dimensions data
