Golden Ratio Face Test

Thirds, five-eye width, eye spacing and face length-to-width, each compared against its reference value so you can see exactly how far off you are.

Front-facing, unobstructed, evenly lit photos work best. Your photo is analysed on your phone or computer and is never uploaded.

Reference values

What we measure against

These are common aesthetic references, not correct answers. Real faces within about 10% of a reference are indistinguishable to the eye.

Facial thirds1 : 1 : 1Hairline to brow, brow to nose base, nose base to chin, all equal.
Five-eye width5.00Face width equals five eye widths, with one eye width between the eyes.
Eye spacing ÷ eye width1.00The gap between your inner corners equals the width of one eye.
Face length ÷ width1.45Chin to hairline, divided by the widest point across your cheekbones.
Mouth ÷ nose width1.50A little below the 1.618 that Western textbooks quote.

The mesh vertex at the top of the head is not your hairline, so we first run the same formulas over MediaPipe's canonical face model to set a baseline, then convert your numbers onto the scale above.

Both were derived from a narrow population centuries ago.

Most held in only a minority of faces, and the vertical ones — the "equal thirds" rule — fared worst. The canons describe an idea, not an average face.
FAQ

Questions people ask

What are the thirds and the five-eye rule?

Thirds: hairline to brow, brow to nose base, and nose base to chin should be about equal. Five-eye: your face should be about five eye-widths across, with exactly one eye-width between the eyes. They are the two most widely used facial proportion references.

How does 1.618 apply to a face?

The usual claims are that face length divided by width should approach 1.6, and mouth width divided by nose width should approach 1.6. We use 1.45 and 1.5, because faces that actually read as attractive cluster there rather than at a strict 1.618.

What if I am a long way off?

Look at which measure it is. Thirds that run long or short are adjusted with a fringe and brow shape; five-eye deviations are adjusted with liner direction. The result card names the single measure most worth working on.
