Canthal tilt test
Canthal tilt is the angle of the line running from your inner eye corner to your outer one, measured against a horizontal. It is the single measurement that most reliably separates upturned, downturned and hooded eyes, so FaceRating reports it in degrees.
What this test measures
Your canthal tilt
The angle between your inner and outer canthi relative to the nose, reported in degrees and placed against the usual reference bands.
What the same scan also measures
One scan returns all of these. You do not need a separate tool for each one.
- Facial symmetry
How closely your left and right halves mirror each other, landmark by landmark.
- Facial thirds
Where your hairline, nose and chin fall against three equal bands.
- Golden ratio
How close your proportions track the constant phi (1.618).
- Jaw taper
The width of your jaw measured against your cheekbones.
- Eye spacing
The distance between your eye centres relative to face width.
Questions about this test
What is a good canthal tilt?
Most people sit between 4 and 8 degrees. Above about 10 reads as upturned, below about 4 as downturned or hooded. FaceRating reports your measured value rather than ranking you against a single ideal.
Does canthal tilt change with age?
The bone structure is fixed, but hooding of the lid increases with age, which lowers the visible tilt. That is why the same person can measure differently across a decade.
