Canthal tilt: measurements, ratios, and research

The slope from the inner to the outer eye corner. Positive tilt means the outer corner sits higher when the head is level.

How canthal tilt is measured

Draw inner-to-outer canthus, then measure its angle to a level horizontal reference. Correct for head roll and measure both eyes separately.

Ratios, ranges & competing claims

6.51° ± 2.67° — Observed in selected male celebrities

Mean canthal tilt in the 21-male celebrity sample was 6.51°.

Observation: The ± value is sample standard deviation, not an acceptable or optimal interval. Using Artificial Intelligence to Quantify Sexual Dimorphism in Aesthetic Faces

≈ 5–8° — Numbers debated in forums

One discussion of Jeremy Meeks estimates his tilt variously around 5–6° and 8.1°.

Forum claim: Unstandardized photos and disagreement between posters. These are unverified estimates, not measurements of the person or validated ideals. Discussion of Jeremy Meeks’ canthal tilt

Practical takeaway

A modest upward outer corner is a useful reference.

The selected male sample supports a positive tilt as a reference appearance. Read tilt together with the entire eyelid contour rather than chasing the steepest angle.

What changes the answer

Head roll, lower-lid shape, eye opening, and brow position change the impression. A tilted photograph can add or subtract several apparent degrees; level the head first.
