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

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.

How does TheFaceScan detect face shape accurately from a photo?

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.

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

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.

Is TheFaceScan truly free with zero paywalls?

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.

Section 01

1. Local execution & zero-storage architecture

TheFaceScan operates as a zero-cloud facial anthropometry utility. When you upload or capture a portrait for analysis, the photo is processed in temporary volatile RAM in your browser using client-side WebAssembly (MediaPipe 478 3D landmark mesh).

Technical guarantee

No facial vectors, coordinate meshes, nor raw photographic buffers are ever transmitted across external networks or stored in persistent server databases during standard scanning.

Section 02

2. Non-clinical & educational advisory

The calculations provided across this utility (including canthal tilt degrees, hemifacial symmetry percentages, Da Vinci thirds, and facial morphology classifications) are mathematical aesthetic heuristics derived from anthropometric literature.

They are provided strictly for educational, styling, and general interest purposes. They do not constitute orthodontic, maxillofacial, dermatological, or diagnostic medical counsel. Consult a board-certified medical specialist for clinical craniofacial assessments.

Section 03

3. Acceptable use & consent requirements

You agree to use this utility only with images you hold lawful rights to analyze or where you have received explicit authorization from the subject. You shall not utilize this utility for:

Harassment, non-consensual biometric indexing, or defamation.
Commercial surveillance, automated profiling, or unauthorized credential matching.
Attempting to reverse-engineer proprietary mathematical weighting models via automated bot scraping.

Section 04

4. Intellectual property & open benchmarks

TheFaceScan software, graphical interface, visual assets, and proprietary coordinate calibration algorithms are protected by copyright and intellectual property standards.

All client reports and coordinate summaries generated from your browser session belong entirely to you and may be exported freely for personal or professional archival.

Section 05

5. Disclaimer of warranties & liability

This utility is made available “as is” without warranties of any kind, whether express or implied. Under no circumstances shall TheFaceScan or its contributors be liable for any incidental, consequential, or indirect damages arising from the use or inability to use the analysis engine.
