One clear front view
Unusable images are rejected instead of receiving a guessed score.
Golden ratio face test, without the 1.618 theatre.
Measure three face ratios and compare them with a fixed reference model. The reading uses the engine’s reference values rather than assuming every ratio should equal 1.618.

More about this measurement
Most golden ratio face tests compare your proportions to 1.618 and score the gap. This one measures the same three ratios and compares them to something else: the values the reference face actually returns. The reference numbers are 1.152, 1.375 and 3.120, and none of them is phi. That is the honest result, and this page is about why.
OUTPUT
Three measured ratios
Face length / width, mouth / nose width and face width / mouth width, with a 0–100 reference sub-score.
01
The three ratios
The golden group is face length to face width, mouth width to nose width, and face width to mouth width. Those three are measurable from a front view with landmarks that correspond to real features, which is why they are the three in the group.
02
Why the face golden ratio is not 1.618 here
Phi describes classical proportion theory stated over anatomical landmarks. What a face-mesh detector returns are mesh vertices, and the two do not line up — the forehead vertex is not a hairline, the face-width vertices are not true zygia. Measured on the canonical face, the three ratios come out at 1.152, 1.375 and 3.120. Scoring you against 1.618 would mean scoring the reference face itself badly, which tells you the ruler is wrong rather than the face.
03
What the golden ratio sub-score means
It means distance from those three measured reference values, combined into one deviation and mapped to 0–100. It does not mean proximity to phi, divine proportion, or a beauty standard. A higher number means your three ratios sit closer to one fixed reference face model.
04
The loosest of the four
This dimension reaches its half-point at a deviation of 0.110 — more than twice the tolerance of symmetry at 0.030, facial thirds and facial fifths at 0.045 and 0.040 respectively. It is also the lightest weight in the composite at 15%. Both numbers are engine constants, fixed in v1.0. The specification sets them without stating a reason.
05
A face golden ratio calculator you can audit
Each of the three ratios is printed with your measured value and the reference band beside it. If you disagree with a reference value you can see exactly which one you disagree with, instead of arguing with a single unexplained percentage.
06
The four weights
Symmetry 35%, facial thirds 25%, facial fifths 25%, and golden ratio 15%. The composite is 0.35 × symmetry + 0.25 × thirds + 0.25 × fifths + 0.15 × golden. The weights are fixed in the frozen engine and printed on every page that shows a score.

FAQ
Questions, answered plainly.
Does this golden ratio face test use 1.618?
No. It compares three measured ratios against the values the engine’s canonical face returns — 1.152, 1.375 and 3.120. Phi describes anatomical landmarks, and a face mesh does not give anatomical landmarks.
Which three ratios are measured?
Face length to face width, mouth width to nose width, and face width to mouth width. All three are front-view measurements.
How much does the golden ratio count toward my score?
It carries 15% of the composite, the lightest of the four weights, and reaches its half-point at a deviation of 0.110, the loosest of the four tolerances. Both are fixed constants in the v1.0 engine, printed on this page so you can check the arithmetic yourself.
Does a high golden ratio sub-score mean my face is beautiful?
No. It means three of your measured proportions sit close to one fixed reference face model. The word beauty is not a variable anywhere in the calculation.
Can two people get the same score with different ratios?
Yes. The three ratios are combined into one deviation before scoring, so different combinations can land on the same sub-score. That is why each measured ratio is displayed separately.
Is the face golden ratio calculator free?
Yes, with no sign-up or payment, and the scan runs entirely in your browser.
