What this measures
The golden ratio face test compares facial proportions against phi, approximately 1.618, across several classical checks. This tool measures four: face length divided by cheekbone width, face length divided by three times the nose-to-chin distance, mouth width divided by nose width, and the nose-to-chin distance divided by nose length. Each is scored by how far it sits from 1.618 and the four are averaged, because any single ratio lands near phi for plenty of faces by coincidence. It is worth knowing what this measures. The idea that beautiful faces follow phi comes from Renaissance drawing convention and from a 1980s cosmetic-surgery mask, not from a finding — measured populations do not cluster at 1.618. A high score means your proportions match a drawing convention closely, which is interesting and is not the same as a fact about your face.
How to read this
- The headline number is face length over cheekbone width. The score is the average across all four checks.
- 1.618 is the target for every check, so a score of 100 would need all four to land on phi at once.
- Real faces spread roughly between 1.2 and 2.1 on the first check. Sitting outside phi is the normal case, not a defect.
- This is the tool on the site with the weakest evidence behind its target, and the copy says so on purpose.
- Face length is estimated the same way the shape detector estimates it — the mesh cannot see your hairline, so the height is 1.5x the glabella-to-chin distance.
Mean adherence to phi across four classical facial proportions.
- Wide of phi 0 – 1.35
- Face is broad relative to its length compared with the classical convention.
- Below phi 1.35 – 1.5
- Common. Sits between the round and oval conventions.
- Near phi 1.5 – 1.72
- Within about 0.1 of 1.618 — the band the convention points at.
- Above phi 1.72 – 3
- Face is long relative to its width compared with the classical convention.
Method
Every measurement here comes from 478 facial landmarks detected by Google's MediaPipe face mesh, running as WebAssembly in your browser. The face is levelled by the eye line before anything is measured, and every distance is normalised so the result does not depend on your camera or how close you stood to it.
Questions
Is the golden ratio actually linked to beauty?
Not in the way it is usually presented. The claim traces to Renaissance drawing practice and to Marquardt's phi mask from the 1990s; attempts to reproduce a preference for phi proportions in measured populations have been mixed at best, and the mask itself has been criticised for encoding one ethnic norm.
What counts as a good golden ratio score?
There is no threshold worth defending. The four checks are averaged, so a score above 70 means most of your proportions land within about a tenth of phi. Whether that is good is a question about the convention, not about you.
Why do golden-ratio calculators disagree?
They measure different distances. Some use hairline to chin, others the top of the modelled forehead; some use jaw width rather than cheekbone width. Each choice moves the ratio by more than the differences people argue about, which is why this tool names the four it uses.
