What is the golden ratio face test?
The golden ratio is a mathematical proportion, approximately 1.618. This face calculator uses it as a disclosed comparison reference for three landmark ratios. Matching phi does not establish beauty, health or harmony in every face. A useful result is one you can inspect: each ratio is shown with the exact spans that produced it.
The three ratios and their formulas
The vertical ratio compares nose-bridge-to-chin with upper-mesh-point-to-nose-bridge. The horizontal ratio compares outer-eye span with mouth width. The third compares nose-bridge-to-nose-base with nose-base-to-upper-lip. These are the definitions used here; they are not interchangeable with hairline-based facial thirds or clinical measurements.
Reading your golden ratio result
The reference-match score averages each ratio’s relative closeness to phi, clipped to a 0–100 scale. It is not a population percentile. Tap a measurement to inspect its lines and compare another well-framed photo if a landmark appears misplaced. Use the broader facial ratios calculator when you want dimensions beyond these three comparisons.
Frequently asked questions
Do you collect my test score?
Yes. We anonymously aggregate overall scores to understand score distributions for the same test on this site and support future percentile displays. These statistics retain only the test type, scoring version and the number of times each score occurs. They contain no individual test records and are not linked to accounts, visitor identifiers, photos or face landmarks. Roast modes, two-person comparisons and progress tracking are excluded. Private reports you choose to save are handled separately as described by each tool.
Does 1.618 mean a perfect face?
No. Phi is a comparison reference here, not a universal beauty rule. Faces can differ from it and still be visually appealing.
Does this measure my hairline or facial thirds?
The face mesh does not locate the true hairline. This calculator names its actual anchors instead of calling the top mesh point a hairline.
Can I see the formulas without buying a report?
Yes. Ratios, formulas and annotated measurements are part of the free golden ratio face test.
