What does a golden ratio face score mean?
The golden ratio is the mathematical constant phi, approximately 1.618. This golden ratio face analyzer compares two measurements from a photograph with that number and draws a geometric overlay. It also calculates a separate facial symmetry score from paired landmarks. These are transparent aesthetic geometry exercises, not validated measures of attractiveness, health, ancestry, or personal worth.
Facial landmark detection uses the local 68-point face model to estimate positions around the eyes, eyebrows, nose, mouth, and jaw. That model has no hairline point and does not directly identify anatomical cheekbones. You therefore mark the center of the hairline yourself. The tool uses the two outer jaw landmarks as a width proxy and labels that limitation beside the results.
The first ratio divides the distance from your marked hairline to the chin by the jaw-width proxy. The second divides the distance from the midpoint between the eyes to the nose tip by the nose-tip-to-upper-lip distance. Both are measured in the image plane. A three-dimensional face projected onto a flat photo can have different apparent proportions when the camera angle or lens changes.
How the phi match and facial symmetry score are computed
Each ratio receives a closeness score of one hundred times the smaller of ratio divided by phi and phi divided by ratio. The overall Golden Ratio Score is the average of the two closeness scores. This definition makes an exact phi ratio score one hundred and treats proportionally opposite deviations consistently. It is a chosen mathematical mapping, not the probability that a face is ideal.
For symmetry, the eye centers define a horizontal axis and its midpoint defines a vertical midline. The paired landmarks are rotated into that coordinate frame, and each left point is compared with the reflected right point. Average mismatch is divided by half the jaw-width proxy, converted to a percentage, and clamped at zero. Head rotation, expression, occlusion, and model error can all lower this photo-based score.
The facial proportions rule of thirds is another artistic convention, often describing forehead, middle-face, and lower-face segments. This tool does not silently substitute it for a golden-ratio measurement. No single convention captures the diversity of human faces. Use the glowing golden lines to explore geometry and compare photographic conditions, rather than judging yourself or another person by a percentage.
Facial proportions and measurement references
| Measurement | Reference used here | Important limit |
|---|---|---|
| Hairline to chin / width | Compare with phi ≈ 1.618 | Manual hairline; jaw width proxy |
| Eye–nose / nose–lip | Compare with phi ≈ 1.618 | Distances are projected in a photo |
| Left/right symmetry | Reflected paired landmark mismatch | Pose and expression affect the result |
| Rule of thirds | Separate artistic convention | Not a validated beauty standard |
| Overall score | Mean of two phi closeness scores | Not a diagnosis or attractiveness rating |
How to use Golden Ratio Face & Symmetry Analyzer
1. Choose one clear photo
Upload a JPG, PNG, or WebP under 20 MB, or open the webcam and capture a selfie. Wait for the locally hosted detector and landmark models to finish loading.
2. Mark the hairline
After the golden landmarks appear, tap the center of your hairline or adjust its height with the slider. Review the two ratios and the separate symmetry score.
3. Save or clear the result
Download Golden Mask Card to create a branded PNG locally. Clear Photo removes the displayed image and measurements. Treat the output as entertainment and aesthetic exploration only.
Key features and technical specifications
68-point local landmark detection (WASM — zero upload)
Leverages a client-side 68-point facial landmark detector running entirely in browser WebAssembly; no image data or video frames ever leave your local device.
Manual hairline tap + accessible height slider
Because 68-point models lack a cranial hairline anchor, users can tap directly on the photo or use a keyboard-accessible slider to precisely mark the upper vertical boundary.
Dual phi (1.618) ratio scoring + facial symmetry metric
Computes two distinct proportions (Hairline-to-Chin / Jaw Width proxy and Eye Midpoint-to-Nose / Nose-to-Lip) against phi (1.618), alongside a rotation-corrected bilateral symmetry score.
Branded golden mask overlay PNG export
Renders glowing golden geometric lines and phi proportion grids onto the canvas with an option to download a high-resolution branded Golden Mask Card locally.
Practical use cases
Study classical facial proportions in art and design
Explore how Renaissance artists and classical sculptors applied the divine proportion (phi ≈ 1.618) to portraiture and facial aesthetics using modern computer vision landmarks.
Analyze lighting, camera angle, and perspective distortion
Compare front-facing portraits shot with wide-angle smartphone lenses versus telephoto lenses to observe how perspective distortion impacts measured 2D facial ratios.
Generate a fun, shareable golden mask visual
Capture a selfie or upload a portrait to create an eye-catching geometric overlay card with symmetry ratings for social sharing, personal curiosity, or creative projects.
Frequently asked questions
Does the model find my hairline?
No. The 68-point model has no hairline landmark. Tap the center of your hairline on the photo, or use the keyboard-accessible height slider. That manual selection changes the first ratio.
Are my face photos uploaded or stored?
No photo or landmark data is sent to a processing server or saved in browser storage. Model assets download from this site. Your image and results remain in memory until cleared or you leave; a PNG is saved only when you download it.
Is a higher score more attractive?
No. The score only measures closeness to selected geometric references under this formula. It is not a scientifically validated beauty ranking and does not account for expression, individuality, or personal preference.
Why does the score change between photos?
Lighting, perspective, head tilt, expression, and landmark estimation can move points. Use a front-facing photo with even light and a neutral expression. Repeated photos are not guaranteed to return identical geometry.
Can I use a webcam or group photo?
A webcam selfie is supported when you grant camera permission. The camera stops after capture or closing the camera. Use exactly one visible face; group photos are rejected to avoid mixing subjects.
