Divine proportion face
Runs in your browser. Your photo is not uploaded.
This divine proportion face tool compares three selected photo ratios with the mathematical number 1.618. Its result panel shows each ratio, its deviation and its closeness percentage; the headline is an overall closeness percentage derived from the mean deviation. Colored lines let you inspect the chosen landmarks. The calculation runs locally in your browser and is a way to explore a selected model of proportions.
Three selected comparisons with phi
The golden ratio is a mathematical relationship that can appear in geometry. Applying it to faces is a popular visual exercise, but there is no single set of facial landmarks that proves universal beauty. Different lists of ratios give different answers for the same face. This page names the particular three ratios it uses so the calculation can be inspected rather than treated as a mysterious score.
Relative deviation from 1.618
The page compares three ratios with 1.618: face length over cheekbone width, mouth width over nose width, and cheekbone width over outer eye-corner distance. For each, it reports relative deviation from that chosen constant and then summarizes the three deviations. These three pairs were selected by convention; they do not define all facial geometry.
Reading the summary against its rows
The headline percentage is closeness, so a higher number means a smaller mean deviation from 1.618 across the three rows. It does not mean higher attractiveness, health or symmetry. The mouth-to-nose row can shift with a smile while the other two stay more stable. In a divine proportion face reading, inspect the individual ratio and its “off by” percentage before relying on the overall bar.
Suppose a hypothetical mouth-to-nose ratio is 1.50. Its relative deviation from 1.618 is about 7%, so the row’s closeness would be about 93%. If the other two ratios were 1.60 and 1.70, their deviations would be much smaller; the overall closeness would combine all three. The divine proportion face panel shows the separate bars precisely so a single low row is not hidden by the headline percentage.
The source of a low row matters. Mouth width can vary with expression, while the face-length row starts at the top of the mesh rather than the physical hairline. The cheek-to-outer-eye comparison depends on whether the lateral landmarks are visible on both sides. When a divine proportion face result changes after a retake, identify which of these three endpoint sets moved before attributing the difference to the person.
Expression alters mouth width
A smile widens the mouth and can alter the mouth-to-nose comparison without any structural change. Camera distance affects projected cheek and nose width differently. A golden-ratio face reading therefore needs a neutral mouth, a direct portrait and clearly placed cheek and eye corners. Inspect which of the three rows drives the overall closeness display. For a neutral mouth in this comparison, read how to take a photo for a PSL rating.
The three comparisons are a chosen model
The three selected ratios are a model choice. A different set of facial measurements could produce a different closeness percentage from the same portrait, and this calculation omits skin, eye opening and profile depth. The reported value is therefore a property of these selected rows, not a test of universal beauty or health.
The mathematical reference 1.618 is identical for men and women, but no male or female beauty target follows from it. A hairstyle, ordinary makeup or a relaxed expression can change a portrait’s presentation. They should be chosen for the person’s preferences, not to push a divine proportion face percentage toward 100.
Read other proportions without phi
Use face proportions for ordinary geometric ratios without a phi comparison. The facial harmony overview also shows independent measurements beside face shape. Neither view should be used to claim that the selected divine proportion face ratios determine overall attractiveness.
Divine proportion face FAQ
Is a golden ratio face always attractive?
No. The three selected ratios cannot establish attractiveness, and the selection itself is a convention.
What is a face beauty ratio?
It is a comparison between two facial distances. Different tools may use different landmarks and formulas.
What does a low deviation mean?
Only that the selected photo ratios are closer to 1.618.
Does smiling change the calculation?
Yes. Mouth width and some eye landmarks can shift with expression.
Is the forehead point my hairline?
No. It is the top of the face mesh, so the face-length comparison is approximate.
Is the photo sent to a server?
No. This proportion calculation runs in your browser.
