Definition
The face is divided into an upper third (hairline to glabella), a middle third (glabella to subnasale) and a lower third (subnasale to menton). The classical ideal is roughly equal thirds, but attractive faces vary widely.
Why it matters
Perceived thirds, not measured thirds, drive judgements. A hairstyle that lowers the visible hairline shortens the upper third. A beard lengthens the lower third. This is why proportion recommendations in your report are mostly grooming, not procedures.
