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.
Eye Spacing
Eye spacing measures the distance between the inner eye corners relative to eye width. Balanced spacing — roughly one eye-width between eyes — correlates with symmetry scores in AI face analysis.
Facial Symmetry
Facial symmetry measures left-right correspondence of landmarks — eyes, brows, nostrils, lip corners, and jaw contour. Near-symmetry correlates with higher harmony scores, though perfect symmetry is rare and unnatural.
FAQ — Eyebrows
How do eyebrows affect face shape?
Brow width and arch influence upper-face width perception. Heavy brows can make deep-set or hooded eyes appear more prominent.
What eyebrow shape is most balanced?
Brows that start aligned with the inner eye, peak above the outer iris, and taper to the outer eye corner are commonly cited as balanced.
Do brows change with age?
Yes. Graying, thinning, and drooping tail hairs alter brow shape and can affect perceived age and eye openness.
