Head To Glabella
The distance from the head to the glabella.
HeadToGlabella
How to measure
Application
Used in eyewear and helmet design to determine forehead protrusion relative to the brow ridge, informing visor and lens clearance.
Posture
Head level, looking straight ahead.
Landmark
The glabella is the smooth flat area directly between the eyebrows. Measured from the glabella to the most forward point of the forehead in profile.
Tool
Rigid ruler or spreading caliper.
Common mistake
The glabella typically sits slightly recessed from the forehead above it. Treat these as two distinct points and do not assume they are at the same depth.
