Canthal tilt: what it is and how it is measured.

Canthal tilt is the angle of the line between the inner corner and the outer corner of the eye, compared with a horizontal line. When the outer corner sits higher than the inner corner the tilt is positive; when it sits lower the tilt is negative.

How canthal tilt is measured

  1. Take a straight-on photo with the face level and relaxed.
  2. Mark the inner corner of the eye (medial canthus) and the outer corner (lateral canthus).
  3. Draw a line between the two points and measure its angle against a horizontal line.

Hexum measures canthal tilt automatically from your scan as one of its 34 metrics, so you do not have to place the points by hand.

Positive, neutral and negative tilt

TypeWhat it means
PositiveOuter corner higher than inner corner
NeutralBoth corners roughly level
NegativeOuter corner lower than inner corner

Looksmaxxing communities often treat a mild positive tilt as more attractive and describe it as giving a more alert look. This is a popular view, not a scientific standard, and perceived attractiveness varies between people and between cultures. Typical tilt also varies naturally across ethnic groups.

What affects how your tilt looks in a photo

  • Head angle. Tilting your head changes the measured angle, so keep the face level.
  • Expression. Squinting, smiling and raised brows move the eye corners.
  • Lighting and lens. Wide-angle phone lenses used close to the face distort proportions.
  • Puffiness and tiredness. Swelling around the eyes can make the area look lower or heavier.

What you can and cannot change

Canthal tilt is mostly set by bone structure and the position of the eye corners, so everyday habits will not change it much. What you can influence is how the eye area looks: sleep, hydration, reducing puffiness, grooming your brows and taking photos at a consistent, level angle. Procedures that alter the eye corners are medical decisions, so talk to a qualified professional rather than relying on an app.

Hexum includes eye-area work in its daily protocol when this is a weaker area for you, and lets you rescan to see any change.

FAQ

Common questions

What is canthal tilt?

Canthal tilt is the angle of the line from the inner corner to the outer corner of the eye, compared with horizontal. A positive tilt means the outer corner is higher than the inner corner.

What is a good canthal tilt?

Looksmaxxing communities commonly prefer a mild positive tilt, but there is no scientific standard for a good tilt and perceptions vary. Treat it as one metric among many.

Can you change your canthal tilt?

Mostly no, because it is largely determined by bone structure and eye corner position. You can change how the eye area looks through sleep, reducing puffiness, brow grooming and consistent photo angles. Medical options should be discussed with a professional.

How does Hexum measure canthal tilt?

Hexum maps facial landmarks from your photo and calculates the angle between the inner and outer eye corners as one of its 34 metrics.

Is canthal tilt the same on both eyes?

Not always. Small differences between the left and right eye are normal and part of facial symmetry.
