About this site and who runs it
This site is built and run by Jim Liu, a solo developer in Sydney. There is no team, no clinic behind it and no company beyond one person. If something here is wrong, it is my fault and you can reach me about it at the contact page.
Why this exists
I built a face measurement tool, and then went to check the numbers everybody in this category quotes. A lot of them do not hold up. The widely cited facial width-to-height range is not in the paper it is attributed to, and I read that paper in full to be sure. An anthropometric degree range for eye angle is sourced to a perception study about baby faces in which the word "canthal" never appears. Two incompatible conventions are both published as "canthal tilt" with nobody flagging it. The nose type vocabulary every tool site uses comes from an 1848 book that assigns personality traits to nose shapes.
Publishing those corrections is most of what makes this site different from the others. It seemed wrong to publish them without saying who was making them, which is what this page is for.
How the measurements are produced
- 1The photo never leaves your browser.Google's MediaPipe Face Landmarker runs as WebAssembly inside your tab and returns 478 points. There is no upload and no server.
- 2Head angle is undone before anything is measured.Using the pose matrix the model returns, so a photo taken slightly tilted is not measured as a tilted face.
- 3Every photo is measured five times.With small shifts each pass. How far the points move between passes becomes that photo's measurement floor, in the same units as the result.
- 4Anything below that floor is withheld.Rather than printed as a confident small number. The same applies to left-versus-right claims on a photo that is geometrically skewed.
- 5Damaged, distorted and off-frame photos are refused outright.A photo that cannot be measured reliably gets a specific reason, not a plausible-looking answer.
What this site does not know
I am a developer. I have no training in anatomy, dentistry, oculoplastic surgery or anthropometry, and nothing here should be read as though I did. Every anatomical statement on this site is attributed to a published source with its sample size, population and method attached, so you can go and disagree with the source rather than with me.
The reference set this site quotes is 43 AI generated faces, not photographs of people. Where you see a percentile or a distribution here, it describes what an image generator produces and how precisely this tool can measure it. It is not a statement about a human population, and it is labelled that way wherever it appears.
Two further things I will not pretend about. The face shape classifier compares you against reference values that were typed in by hand rather than derived from a measured population, and the page says so. And the tool cannot reliably identify a diamond face shape at all, because the landmark model has no hairline point, which is written up in full on the diamond face shape guide rather than quietly left out.
How this is paid for
Nothing on the site is paid for today. There are no ads, no affiliate links, no sponsored placements and no account. A paid written report is planned, built from your measurements rather than your photo, and if that ships this page will say so. If anything here ever becomes commercial, it gets disclosed here first rather than discovered in the markup.
