Free face shape detector that runs entirely in your browser — your photo never leaves your device.
FaceRuler measures a face from a single photo and returns the face shape (one of seven), a score on the PSL 0–8 scale, a percentile, and eight metric readings: symmetry, facial thirds, golden ratios, eye spacing, FWHR, jaw width ratio, canthal tilt and eye aspect. Everything runs in the browser with MediaPipe's 478-point face landmark model compiled to WebAssembly, so the photo never leaves the device. Scoring is deterministic geometry rather than a guess, so the same landmarks always produce the same report. Free, no sign-up, no upload.
