Upload a photo and see how closely your facial proportions match phi (1.618) — the ratio behind the classical "golden ratio face" concept. Runs entirely on your device; nothing is uploaded.
Processed on your device — your photo is never uploaded anywhere.
When you upload a photo, on-device AI maps dozens of points across your face — forehead, chin, cheeks, eyes, and mouth — entirely inside your browser. From those points, we measure three classic golden-ratio comparisons: face length to face width, face width to mouth width, and mouth width to the distance between your inner eye corners. Each is scored on how close it lands to 1.618, then averaged into one overall score.
Photo angle, camera lens distortion, expression, and lighting all shift the measurements — this is a proportion estimate from a 2D photo, not a clinical measurement. And phi itself is one framework among several for describing facial proportion; it's popular because it's easy to explain, not because it's the strongest predictor of attractiveness. Use it as a curiosity, not a verdict.
The golden ratio, or phi (1.618), is a proportion that shows up throughout nature and classical art. Applied to faces, it compares pairs of measurements — like face length to face width, or mouth width to eye spacing — to see how close each ratio lands to 1.618.
There's no pass/fail score. In practice, 85%+ is unusually close to phi and genuinely rare, 70-84% shows strong alignment on several proportions, and 55-69% is where most real faces land. A lower score isn't a flaw — it just means this specific mathematical ratio doesn't describe your proportions closely.
Not on its own. Research on facial attractiveness points to symmetry, averageness, and skin quality as stronger predictors than golden-ratio adherence specifically. Treat this as a proportion measurement, not a verdict — plenty of faces widely considered attractive don't match phi closely.
No. Face detection and every measurement run locally in your browser using on-device AI. Nothing about your photo is sent to a server at any point.
This works best with a single, forward-facing, well-lit photo with your whole face visible. It'll skip photos with no clearly detectable face or more than one face.
This tool checks one mathematical ratio. Our full face score breaks down 50+ parameters — symmetry, skin, jawline, hairline, and more — with a personalized plan to improve what it finds.
