How to measure
Application
Used in helmet chin strap length design and medical craniofacial assessment.
Posture
Head level, looking straight ahead, jaw relaxed and teeth lightly together.
Landmark
Measured from the most prominent point of the chin to the most rearward point of the skull.
Tool
Tape measure.
Assistance
A second person should locate the rearmost skull point and hold the tape end in place.
Common mistake
Jutting the chin forward or clenching the jaw inflates the result. Keep the jaw fully relaxed.
