Golden Ratio33% : 33% : 33%

The Face Horizontal Ratio is based on dividing the face into three equal sections: from the hairline to the bottom of the eyebrows, from the bottom of eyebrows to the bottom of the nose, and from the bottom of the nose to the tip of the chin. The golden ratio, or ideal proportion, between the three is 1:1:1.

What Is Canthal Tilt?

Canthal tilt is the angle of the line running from the inner corner of your eye (medial canthus) to the outer corner (lateral canthus), measured against horizontal.

Tilt the outer corner up and it reads as positive, or "upturned" - the lifted, almond shape behind the viral "fox eye" and "hunter eyes" look.

Drop it down and it reads as negative, or "downturned." Level corners land in between as neutral.

Positive Tilt, Negative Tilt, and the “Hunter Eyes” Wave

Positive canthal tilt reads as alert and lifted; negative reads as softer, neither is a flaw, both are normal anatomy.

What's changed is demand: looksmaxxing and “hunter eyes” content have turned a niche anatomy term into mainstream search volume.

Brands' Opportunities

Brands that let visitors see their own eye angle, instead of reading about it, convert that curiosity into a makeup cart, an eyewear try-on, or a booked consultation.

Canthal Tilt Detector FAQ

What is canthal tilt?

Canthal tilt is the angle between the inner corner (medial canthus) and outer corner (lateral canthus) of your eye, measured against a horizontal line. It's a geometric description of eye shape, not a health or beauty verdict.

What is a positive canthal tilt?

A positive canthal tilt means the outer corner sits higher than the inner corner, the upturned, almond-shaped look often linked to “fox eye” and “hunter eyes” styling. Perfect Corp's Face Analyzer labels this result Upturned.

How is canthal tilt measured?

Perfect Corp's AI detects facial landmarks, locates each eye's medial and lateral canthus, and compares the resulting line to a horizontal reference. Left and right eyes are scored independently as Downturned, Upturned, or Average, so you also see any left/right asymmetry.

Can canthal tilt be changed?

Makeup, lash styling, and brow shaping can visually shift how lifted the eye appears without moving the canthus itself. Surgical options like canthopexy exist but carry real risks and should only be discussed with a qualified specialist, never decided from an online score alone.
