00Golden ratio face
Golden ratio face calculator: how close is your face to 1.618?
Take or upload one front-facing selfie. The golden ratio face calculator measures three ratios on your face, compares each with phi (1.618) and draws every line on your photo, so you can check each number yourself. Your photo stays in your browser.

01The three golden ratio face measurements
Each ratio is one length divided by another, both measured between points the calculator finds on your face. Phi is about 1.618; the closer a ratio is to it, the higher that ratio's match.
- Lower ÷ upper face
- From the bridge of your nose down to your chin, divided by the top of your forehead down to the bridge of your nose. Both are measured along your face, so a tilted photo reads the same.
- Eye span ÷ mouth width
- The distance between the outer corners of your eyes, divided by the width of your mouth from corner to corner.
- Nose ÷ philtrum
- The bridge of your nose down to the base of your nose, divided by the base of your nose down to the top of your upper lip (the philtrum).
02How the golden ratio face match is worked out
Each ratio's match is 100 × (1 − the gap between your ratio and 1.618, divided by 1.618), and never less than 0. A ratio of 1.67 matches 97%, 2.01 matches 76% and 2.34 matches 55%. Your overall match is the plain average of the three. It says how close these three numbers are to one reference value, nothing more: it is not a beauty score and it does not go into our attractiveness test.
03What real faces measure
In the front-facing photos we used as a reference, most faces fall between 2.23 and 2.62 for lower ÷ upper face, 1.63 and 1.88 for eye span ÷ mouth width, and 2.74 and 3.82 for nose ÷ philtrum. Only the eye ratio usually lands near 1.618. A nose ratio well above phi is normal: in most adults the nose is about three times as long as the philtrum.
04Is the golden ratio the standard of a beautiful face?
No. Phi (1.618) is a number from geometry, and the idea that beautiful faces follow it is popular but not proven: studies that measure real faces find attractive faces at many different ratios. The golden rectangle and spiral below only show what phi is; this golden ratio face calculator doesn't fit them to your face, and most of your readings are not expected to equal 1.618.
05How to take the photo
- 01Face the camera straight on, with the phone at eye level. Tilting your chin up or down changes the face and nose ratios most.
- 02Keep your mouth closed and relaxed: a smile widens your mouth and lowers the eye ratio.
- 03Pull hair back off your forehead so the top of your face can be found.
- 04Use even light from the front, without strong shadows under the nose.
- 05Hold the phone at arm's length; very close photos stretch the middle of the face.
06How the golden ratio face calculator works, and its limits
Your browser finds 478 points on your face and measures between the ones at the top of your forehead, the bridge and base of your nose, the top of your lip, your chin, and the corners of your eyes and mouth. The top of that mesh sits on the forehead, not at your hairline, so the face ratio is not the classic hairline-to-chin one. The ratios move with expression, camera distance and head tilt, so retake the photo if one looks off.
07Golden ratio face questions
01How does the golden ratio face test work?
Take one straight-on selfie with your mouth closed and your forehead clear. The golden ratio face calculator measures three ratios on your face (lower to upper face, eye span to mouth width, and nose to philtrum), compares each with 1.618 and shows the lines it measured, so you can redo the division yourself.
02What is the golden ratio of a face?
The golden ratio, or phi, is about 1.618. A golden ratio face is the idea that certain lengths on a face divide into each other at 1.618. There are many versions of that idea; this calculator uses three published ratios and tells you exactly which points each one is measured between.
03What is a good golden ratio face match?
There isn't a good or bad match. In our reference photos most people's average match sits between 46% and 55%, mostly because the nose ratio is naturally well above 1.618. A higher match only means your three ratios are closer to one number.
04Does a golden ratio face make you more attractive?
Not as far as anyone has shown. Research on real faces finds attractive faces at a wide range of ratios, and features such as symmetry, skin and expression matter in ways phi doesn't capture. Your golden ratio match doesn't go into our attractiveness score.
05Is this the golden ratio face mask?
No. The golden ratio mask is a drawn template laid over a face. This calculator doesn't use a template: it measures your own landmarks and reports three ratios as plain numbers, each with the lines it came from.
06Is my photo uploaded?
No. The golden ratio face calculator runs entirely in your browser and never uploads your photo or the points found on your face.
