Canthal Tilt: The Eye Angle Metric, Explained & Measured
Canthal tilt is the angle of the line between your inner eye corner (near the nose) and outer eye corner (toward the temple). Positive tilt — outer corner higher — is the community's ideal; +4° to +8° is the reference band. Our tool measures it from the same landmarks surgeons use.
Reference values
| Reading | Interpretation |
|---|---|
| Negative (< 0°) | Outer corner lower — reads "sad/tired" |
| 0° to +4° | Neutral band |
| +4° to +8° | Reference band (community ideal) |
| > +10° | Strong tilt; increasingly rare naturally |
What moves the perceived tilt
Honestly labeled: brow position and grooming shift the perceived tilt line most (brow shaping is the cheapest lever — moderate evidence). Sleep and hydration reduce puffiness that flattens the reading. Actual bone-level tilt doesn't change without surgery — and surgical canthoplasty exists but carries real risk; we describe, never push.

The tool below reads canthal tilt from both eyes, roll-corrected, on your device — the same measurement path every report on this site uses.

FAQ
What is a good canthal tilt? The community reference band is +4° to +8° positive tilt. Note "hunter eyes" — the related ideal — is about tilt plus lid posture, covered here.
Can you improve canthal tilt? Perceived tilt yes (brows, puffiness); bone-level tilt no, short of surgery. Evidence grades in our deep report label each lever honestly.
Is canthal tilt really that important? It's one of eight metrics — the eyes dimension carries 15% weight in our engine. It's discussed disproportionately online because it's photogenic, not because it's everything.
