Phi comparisons
Checks face-to-cheek, mouth-to-nose and cheek-to-mouth relationships against 1.618.
Local ratio tool
Golden Ratio Face Calculator
Measure selected photo ratios against 1.618 and a one-eye-width reference. Each value, reference and difference is shown so the result remains inspectable.

Before you analyze
- 1Use your own photo, or one you have permission to use.
- 2One adult face only. No minors or age estimation.
- 3Results describe this photo, not objective beauty or health.
A typical first run loads about 15 MB of model/runtime files, then the browser caches them. Nothing is submitted to our analysis API.

What it measures
Evidence behind this result
The output is built from inspectable photo geometry and a separate image-quality signal.
Classical spacing
Shows inter-eye spacing relative to average visible eye width.
Per-ratio difference
Keeps every input visible rather than presenting an unexplained golden score.

How this tool works
Locate
The model detects contour, eye, nose and mouth landmarks in the browser.
Divide
Distances are converted to scale-independent ratios in image-pixel coordinates.
Compare
Log-distance from each reference becomes a proximity value for easy inspection.

What the result cannot tell you
01
Phi is a mathematical reference, not a scientifically universal definition of beauty.
02
Different publications select different facial landmarks and ratio definitions.
03
Perspective, expression and landmark visibility can shift the measured values.
Does a higher golden-ratio result mean more attractive?+
No. It only means the selected two-dimensional measurements are numerically closer to the listed references.
Why is eye spacing compared with 1.0 instead of 1.618?+
The classical facial-fifths reference describes an eye gap of roughly one visible eye width, so the page labels that separate reference directly.
Are photos sent to a server?+
No. This calculator runs its face landmark model and ratio calculations in your browser.
