Chin-neck angle

cervicomental angle

A smaller angle means a sharper line from jaw to neck. Head position and the soft tissue under the chin change it.

How it's measured

Angle at the deepest point between chin and neck (cervical point) between the line forward to the bottom of the chin (menton) and the line down the front of the neck (neck point).

In the score

Counts toward the score with weight 10 (Community formula point table: submental cervical angle, 10 points).

What changes it

• Measured on the skin outline, so muscle and soft tissue affect it as well as bone.
• Head turn or tilt changes it. Keep the head level and face the camera.

One number, one feature

One measurement describes one detail in one photo. Pose, lens and expression move it, and every reference range is an average from limited samples.
