Jawline
The jawline defines the lower face contour from ear to chin. Its angle, width, and definition strongly influence face shape classification and perceived masculinity or femininity in AI facial analysis.
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.
Neck & Jaw-Neck Transition
The neck and jaw-neck transition (cervicomental angle) affect profile aesthetics and perceived age. Definition here complements jawline scoring and influences overall facial harmony in full-head portraits.
FAQ — Chin
What is a weak chin?
A weak (recessed) chin sits behind the lower lip in profile, reducing lower-face projection and sometimes creating a less defined jaw-neck transition.
Does chin shape affect face shape category?
Yes. Pointed chins suggest heart; wide square chins suggest square; narrow chins appear in diamond and oval shapes.
Can chin appearance change?
Weight changes, posture, and age-related bone and soft-tissue shifts all alter chin projection and definition.
