How to measure

Application

Used in helmet front edge design, headband sizing, and medical facial proportion assessment.

Posture

Head level, looking straight ahead.

Landmark

Measured across the widest point of the forehead, typically just above the eyebrows.

Tool

Rigid ruler or spreading caliper.

Clothing

Push all hair back fully to expose the skin surface at the forehead edges.

Common mistake

Hair covering the forehead edges artificially narrows the measured width.
