Golden ratio face calculator: your proportions vs 1.618
Last updated: September 2026
The golden ratio, 1.618, is the proportion classical artists used to lay out a face, and the one every "golden ratio face" test compares you with. Upload one front-facing photo and the calculator measures four of those ratios from 478 landmarks in your browser, shows yours next to the classical value, and scores how close you sit overall. Free, no signup, nothing uploaded.
The four ratios the calculator measures
| Ratio | Classical ideal | What it says |
|---|---|---|
| Face length to face width | 1.618 | A face 1.6 times as long as it is wide is the classical oval. Measured here from the top of the face mesh, which sits just under the hairline, so it reads lower than a ruler on the real hairline would; the calculator allows for that. |
| Mouth width to nose width | 1.618 | The mouth should be about one and a half times the width of the nose. Wider reads as a full, expressive mouth; narrower as a small mouth or a wide nose. |
| Nose width to eye spacing | 1.0 | The nose should be as wide as the gap between the eyes. This is the ratio that most often reads off in photos taken close with a wide lens. |
| Mouth width to pupil spacing | 1.0 | The corners of the mouth should fall under the pupils. |
Each ratio scores from 0 to 100 as it moves away from the ideal, and the four average into the golden ratio score. A score in the seventies is typical. Ninety and above means every ratio sits close to the canon at once, which is rare.
Does the golden ratio really predict attractiveness?
Partly. Studies that measured real faces find that the ratios which matter most are the ones about balance across the face (the thirds and fifths, eye spacing, mouth to nose), and that faces rated most attractive sit near the population average on them rather than at some magic number. The 1.618 figure itself is a Renaissance drawing convention more than a biological constant, which is why this calculator reports the ratios that proportion analysis actually uses and treats 1.618 as a reference, not a target. Nobody has a perfect golden ratio face, and the faces people call perfect do not either.
How the measurement works
The page loads a face landmark model into your browser and finds 478 points on the face: the corners and lids of the eyes, the brows, the bridge and base of the nose, the lips, the cheek edges, the jaw corners and the chin. It then levels the head, corrects for a small turn or a camera held above or below eye level, and measures distances and angles between those points. Every number is a ratio, so the size of the photo does not matter.

What moves a golden ratio score
- Lens and distance. A phone held close enlarges the nose relative to the mouth and eyes. Step back and zoom.
- Hair over the forehead hides the top of the face and shortens the length ratio.
- Expression. A smile widens the mouth ratio; pursed lips narrow it. Use a neutral face.
- Head turn compresses one side and every width ratio with it.

How to get an accurate measurement
- Camera at eye level, at arm's length or further. A low camera lengthens the chin and widens the jaw; a high camera shrinks them.
- Even light from the front. A window behind you or a lamp above you puts shadows exactly where the landmarks are.
- Face the camera straight on with a neutral expression, mouth closed, hair off the forehead.
- No filters, no beauty mode, no crop that cuts the chin or the ears.
- Use the same setup when you compare two photos. Different setups produce different numbers on the same face.
FAQ
Is the golden ratio face calculator free?
Yes. It runs in your browser from one photo with no signup and no upload.
What is a good golden ratio score?
Seventies is typical. Eighty and above means most ratios sit close to the classical values; ninety and above is rare.
Does anyone have a perfect golden ratio face?
No. Faces rated most attractive measure near the classical ratios on some measurements and off on others. Use the score as a map of which proportions stand out, not as a target.
Why is my face length ratio below 1.6?
The face length is measured from the top of the face mesh, which sits a little under the hairline, so everyone reads lower than a hand measurement to the hairline. The calculator allows for it in the score; the raw ratio is shown so you can compare with your own ruler.
Which ratios matter most?
Eye spacing and mouth to nose. They describe balance across the face, which studies link to attractiveness ratings more strongly than face length does.
Is my photo uploaded?
No. The measurement runs on your device.
