Top Of Head To Stomion
The distance from the top of the head to the stomion point.
TopOfHeadToStomion
How to measure
Application
Used in medical craniofacial assessment and full-face mask design to determine vertical face height from the crown of the head.
Posture
Head level, looking straight ahead, lips relaxed and closed.
Landmark
The stomion is the centre point where the upper and lower lips meet. Measured vertically from this point to the top of the head.
Tool
Tape measure or rigid ruler.
Assistance
A second person should hold the tape end at the top of the head and confirm it is at the true crown.
Common mistake
Measuring to the base of the nose rather than the centre of the lip line gives a shorter result.
