HeadBreadth
How to measure
Application
Used in helmet, headset, and headwear design as the primary lateral skull dimension for fit sizing.
Posture
Head level, looking straight ahead.
Landmark
Measured at the widest point of the skull, typically above and behind the ears.
Tool
Spreading caliper.
Assistance
A second person should position the caliper at the true widest point of the skull.
Common mistake
Measuring across the ears rather than the skull gives a wider and incorrect result.
