Question 1

How is Canthal Tilt measured and what is considered positive tilt?

Accepted Answer

Canthal tilt is the angle of the palpebral axis connecting the inner eye corner (medial canthus) to the outer corner (lateral canthus). A positive tilt (+2° to +6°) occurs when the outer corner sits higher than the inner corner, creating an alert, refreshed aesthetic appearance.

Question 2

How does TheFaceScan detect face shape accurately from a photo?

Accepted Answer

TheFaceScan uses 478 high-precision facial landmarks to calculate the exact ratios of cheekbone width (bizygomatic breadth), jawline width (bigonial breadth), forehead width, and total face length, mathematically classifying the structure into Oval, Square, Round, Diamond, Heart, or Oblong archetypes.

Question 3

What is an ideal compact midface ratio (1:1)?

Accepted Answer

The compact midface ratio compares the distance between the pupils (interpupillary distance) to the vertical distance between the eye line and upper lip. A ratio near 1.0 is considered the modern aesthetic benchmark for compact, harmonious facial proportions.

Question 4

Is TheFaceScan truly free with zero paywalls?

Accepted Answer

Yes, TheFaceScan is completely free. Unlike apps that charge $6.99 to $9.99 per week, all calculations—including canthal tilt, face shape, symmetry, and golden ratios—run directly in your browser on TheFaceScan.com without paywalls or credit cards.
