LOOKS & EYE GEOMETRY · CANTHAL TILT
Canthal Tilt Calculator: measure your eye tilt in degrees.
Drop one front-facing photo to measure your left, right, and average canthal tilt angle in degrees from 478 MediaPipe landmarks - roll-corrected against your interpupillary axis so slight head tilt never distorts the reading.
- Roll-corrected medial-to-lateral canthus angle for Left, Right, and Average eye tilt
- Positive (> +2°), Neutral (-1° to +2°), or Negative (< -1°) classification
- Interactive vector overlay showing your inner/outer eye corners and horizontal baseline
- 100% private on-device calculation - your photo never leaves your browser

Canthal Tilt Reference Scale (Degrees)
Canthal tilt measures the angle between your medial canthus (inner tear duct corner) and lateral canthus (outer corner) against your roll-corrected pupil line:

FAQ
What is a positive, neutral, or negative canthal tilt?
Canthal tilt is the angle formed by a line connecting the inner eye corner (medial canthus) to the outer eye corner (lateral canthus) relative to the horizontal interpupillary plane. A Positive Canthal Tilt (+2.0° to +8.0°) means the outer corner sits noticeably higher than the inner corner. A Neutral Canthal Tilt (-1.0° to +2.0°) sits roughly level, and a Negative Canthal Tilt (below -1.0°) means the outer corner sits slightly lower than the inner corner.
Why does the calculator roll-correct my photo before measuring?
Without head-roll correction, tilting your head just 3 degrees to the left or right in a selfie would add +3° to one eye and subtract 3° from the other. Our 478-landmark detector locks onto both pupil centers (landmarks 468 and 473) to establish a true horizontal baseline first, then measures each eye's medial-to-lateral canthal vector against that baseline.
Why do my left and right eyes have slightly different canthal tilt angles?
Almost every human face has 0.5° to 1.8° of natural bilateral asymmetry between the left and right orbital rims. Camera yaw (turning your head slightly toward one shoulder) can also make the closer eye appear slightly differently angled than the farther eye.
