MidfaceHow AI measures this feature and photo tips
The midface spans from the brow ridge to the nose base, housing the eyes, cheeks, and nose. Midface length and compactness strongly influence perceived age — shorter midfaces often read younger.

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.
Cheekbones
Cheekbones (zygomatic arches) mark the widest or most prominent lateral point of the midface. High, defined cheekbones create structural shadow and are central to diamond and heart face classifications.
Nose
The nose anchors midface proportion — its width, length, and projection balance the eyes and mouth. Nasal geometry interacts with facial thirds and contributes to profile harmony in AI analysis.
FAQ — Midface
What is midface length?
Midface length is the vertical distance from the brow to the nose base — a key proportion in facial harmony analysis.
Does a long midface age you?
Longer midfaces can read mature in some contexts, but age perception depends on combined signals — skin, eyes, and bone structure.
How does AI measure midface?
Landmarks at brow, pupil, and subnasale define midface proportions in Smile Tracker's facial proportion model.
