The canthal tilt is reported in degrees. Positive numbers mean your outer canthus is lifted above your inner canthus — the "hunter eyes" configuration most surveyed-attractive in preference studies. Negative numbers mean it's below — the "downturned eyes" or "puppy eyes" configuration. Where you fall:
+5° to +7° — Hunter Eyes
Strong positive canthal tilt — the most-rated-attractive range across published preference studies. Outer corners noticeably lifted toward the temple. Often described as 'cat-eye,' 'almond,' or 'hunter eyes.'
+2° to +5° — Lifted
Clear positive tilt. Subtle but visually present — the most common positive-tilt range and considered attractive in survey research without crossing into surgical territory.
0° to +2° — Neutral
Approximately horizontal eye axis. Reads as warm, friendly, balanced. Neither lifted nor downturned — the default in roughly 35% of adults.
-3° to 0° — Slightly Downturned
Outer corners slightly below inner. Reads as gentler, softer, more approachable. Common and often described as 'puppy eyes' or 'sad eyes.'
Below -3° — Negative Tilt
Strongly downturned. The full distance from a hunter-eye-style positive tilt. Sometimes congenital, sometimes age-related laxity of the lateral canthus.
Of every measurable feature of the eye, canthal tilt is the one that most strongly affects perceived expression and attractiveness. The eye axis sets the "mood" the face projects before any conscious read of features: lifted = alert, sharp, confident; downturned = warm, gentle, approachable. Both have aesthetic appeal, but preference studies consistently rate moderate positive tilt (+2° to +7°) as the most-attractive range across observers.
What positive tilt signals
What neutral / negative tilt signals
We locate four landmarks from the MediaPipe 478-point face mesh — the inner and outer canthi of both eyes — then compute the angle of the inner→outer line relative to horizontal. Positive when the outer corner is higher than the inner. We report:
The same photo always returns the same numbers — no LLM hallucination, no vibes-based scoring. The lines and angles are drawn on your photo so you can verify the measurement against your face.
Level head, square camera
Tilting your head left or right swings the canthal tilt measurement directly — a 5° head tilt adds 5° to one eye and subtracts 5° from the other. Hold your phone level, with your face square to the lens.
Eye-level camera
Looking up at the camera (chin-up) compresses the vertical distance between inner and outer canthi, reducing apparent tilt. Looking down exaggerates it. Keep the camera at exact eye level.
Neutral, eyes-open expression
Smiling pulls the outer canthus laterally and slightly down; squinting hides the inner canthus. A relaxed, fully-open-eyed neutral expression gives the most stable tilt measurement.
Hair off the temples
Hair covering the outer canthus blocks landmark detection on that side, making the algorithm guess the outer corner position. Brush hair back so both outer canthi are clearly visible.
Canthal tilt is the angle between the line connecting the inner and outer corners of your eye (the medial and lateral canthi) and the horizontal plane. Positive tilt means the outer corner is lifted above the inner corner; negative tilt means the outer corner sits below the inner. It's one of the most-discussed measurements in eye aesthetics because it strongly affects perceived eye shape, expression, and attractiveness.
A positive canthal tilt means the outer canthus (lateral corner) is positioned higher on the face than the inner canthus (medial corner). It's the configuration commonly described as 'hunter eyes,' 'almond eyes,' or 'cat-eye.' Most surveyed-attractive faces have positive tilts in the +2° to +7° range, with peak preference near +4°.
A negative canthal tilt means the outer canthus is lower than the inner canthus, giving a downturned eye appearance. It's sometimes congenital and sometimes age-related (the lateral canthus tends to descend with age due to ligament laxity). Negative tilt is associated with softer, gentler facial expressions; preference studies rate strong negative tilts (more than -5°) as less attractive on average, though many highly attractive faces have neutral or slightly negative tilts.
Clinically, canthal tilt is measured as the angle between the intercanthal axis (line through both inner canthi) and the line connecting the inner and outer canthus of one eye, measured from a frontal photograph or clinical exam. Our tool measures it directly from MediaPipe's 478-landmark face mesh: we locate the inner and outer canthus on each eye and compute the angle of the resulting line relative to horizontal. We report left, right, and average — most faces are slightly asymmetric.
Across multiple preference studies and surveys (most commonly cited: Knapp 1986; Naini and colleagues' work on orthognathic preferences; and large internet surveys conducted by oculoplastic surgery groups), peak attractiveness ratings cluster around +4° canthal tilt. The broader attractive range is +2° to +7°. Above +8° starts to read as overly surgical or surprised; below 0° crosses into downturned territory. There is no single 'perfect' number — preferences vary by gender, ethnicity, and individual face context.
Adult skeletal anatomy fixes the bony canthal positions, so the underlying tilt isn't changeable through exercise or mewing. Surgical options include lateral canthopexy (anchoring the outer canthus higher) and canthoplasty (reshaping the canthal angle); both are oculoplastic procedures with real risks and recovery time. Non-surgical options that affect APPARENT tilt without changing the underlying anatomy: brow shape (a higher arch toward the temple lifts the perceived eye axis), eyeliner technique (winged liner adds visual lift), eyelash extensions toward the outer corner.
Mild asymmetry — typically 1° to 2° — is normal; almost no face has perfectly symmetric canthal tilts. Larger asymmetries (more than 3°) often reflect (a) a tilted head in the photo, (b) sleeping habit asymmetries that affect lateral canthus position over time, or (c) congenital differences. To get the most accurate measurement, take a level, eye-to-eye photo with neutral expression and try not to tilt your head.
It's the same measurement. 'Hunter eyes' is the looksmaxxing community's name for eyes with a strong positive canthal tilt (typically +4° or higher) combined with low eyelid exposure (the upper eyelid covering some of the iris). A score in our tool reflects only the canthal tilt component; the visible scleral exposure that hunter-eyes-discourse also values is a separate eyelid measurement.
