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.
Eyebrows
Eyebrows frame the upper face and interact with eye shape, forehead proportion, and expression. Arch height, thickness, and spacing affect perceived emotion and canthal tilt appearance.
FAQ — Canthal Tilt
What is positive canthal tilt?
Positive canthal tilt means the outer eye corner sits higher than the inner corner, creating an upturned eye axis.
Does canthal tilt affect attractiveness?
Research links positive tilt with youth signals in some populations, but attractiveness depends on overall facial harmony.
Can tilt change with age?
Lateral canthal laxity can reduce positive tilt over time, making outer corners appear lower.
