The "eye angle" (also called canthal tilt) has become one of the most-talked-about facial metrics on the internet. It is also one of the most over-claimed. Here’s a plain-English primer that matches how Face Rank actually computes the score.
What it measures
The eye angle is the slope of the line drawn from your inner eye corner (the medial canthus, near the bridge of the nose) to your outer eye corner (the lateral canthus, near the temple).
- Positive tilt: outer corner higher than inner corner.
- Neutral: outer corner roughly level with inner corner.
- Negative tilt: outer corner lower than inner corner.
What Face Rank rewards
We reward a slight positive tilt of around 5–10 degrees, which is the natural anatomical range for most adults. Pure neutral is also rewarded; we only start subtracting points when the tilt is strongly negative or extreme in either direction.
What changes it (and what doesn’t)
Eye angle is mostly anatomical and doesn’t change with technique. What can change is the apparent tilt on camera:
- If you tilt your head forward (chin down), the apparent tilt becomes slightly more positive.
- If you tilt your head backward, the apparent tilt looks more negative.
- Squinting or smiling with the eyes (the so-called Duchenne smile) doesn’t change the corner positions much, but does change the eye shape that surrounds them.
Don’t take it too seriously
The eye angle is one of five inputs and not the heaviest one. Symmetry, balance and jawline carry more weight in the overall Face Score. The corner tilt is interesting trivia and one of many indicators — not a verdict on you.
