Forehead
Forehead height and width define the upper third of the face. A wide or high forehead influences heart and oval classifications, while a narrow forehead characterises triangle and some diamond shapes.
Facial Thirds
Classical proportion divides the face into three equal vertical zones: upper (hairline to brows), middle (brows to nose base), and lower (nose base to chin). Deviations signal unique character and affect harmony scores.
Temple Width
Temple width contributes to upper-face silhouette alongside forehead and cheekbones. Narrow temples characterise diamond faces; wide temples appear in heart and some round shapes.
FAQ — Hairline
How does hairline affect face shape?
A high or receding hairline increases upper third length, potentially shifting classification toward oblong or heart shapes.
What is a widow's peak?
A V-shaped point at the centre of the hairline, common in heart face shapes and independent of hair loss.
Can hairline change face analysis results?
Yes. Forehead exposure directly affects upper third ratios used in proportion scoring and shape classification.
