Golden ratio face calculator: your φ score

The golden ratio, often written φ, is about 1.618. Renaissance artists used it in composition, and in the twentieth century some cosmetic surgeons proposed facial masks built from it. The idea became popular online as a way to score beauty.

Modern research is more cautious. Faces rated attractive in studies tend to be average, symmetrical and healthy-looking, and their ratios cluster near but not exactly on 1.618. So a high score means some of your proportions happen to land near φ, not that you're objectively more attractive.

For a fair result, use a photo taken from at least arm's length, straight on, with a neutral expression. Close-up selfies widen the nose and shorten the face, which shifts several ratios at once.

If you want to compare your result over time, keep the setup identical: same distance, same height, same light and a neutral face. Small changes in posture move the lower-face ratios most, while mouth and nose widths stay steadier from photo to photo. Averaging three photos gives a more stable figure than relying on one.

Treat the per-ratio scores as the useful part. A high mouth-to-nose match with a lower face-length match, for example, simply means your face is a little wider than the classical template, which many people consider a youthful trait. No single proportion makes or breaks a face.
