Golden ratio face calculator: test your face against 1.618

What is golden ratio?

Your face height, from the top of the forehead to the chin, divided by your face width across the cheekbones, compared with the classical 1.618 proportion.

How Facemap measures golden ratio

Both distances are taken from the 478-point landmark mesh, so the ratio does not depend on how far you sat from the camera. When the forehead is partly covered, the reading is given less weight rather than scored as if the hairline were visible.

What the typical range looks like

Real faces rarely land exactly on 1.618. A ratio close to it reads as a longer, balanced oval; a lower ratio reads wider and more compact. Neither is wrong, it is a description of your proportions.

How to read your result

Treat the golden ratio as a descriptive lens, not a law of beauty. It is useful because it makes the balance between length and width visible and comparable over time.

The golden ratio formula: how we calculate it

Face height against face width. Landmark numbers are MediaPipe Face Landmarker indices, and every distance is normalised to your own face so camera distance and image size cancel out.

dist(10, 152) / dist(234, 454)

Reference target

Tolerance band

0.26

Your reading is compared with that published reference on a Gaussian match curve: score = round( 100 x exp( -0.5 x ( (reading - target) / tolerance )^2 ) ), clamped to 1 to 99. Basis for the reference value: the classical golden section, used as a reference point, not a law of beauty. The headline Attractiveness Score works differently: all readings are corrected for head angle and expression, weighted by confidence and mapped onto a 1 to 100 scale by a model calibrated against a published research set of more than Facemap scans.

Golden ratio reference table

Face height to width and how each band reads.

• 1.55 to 1.68Close to phi

  Length and width sit near the classical 1.618 proportion

• 1.40 to 1.55Slightly wide

  A balanced face that reads a little broader than phi

• Below 1.40Wide

  A compact, wide proportion

• Above 1.68Long

  A longer proportion than phi

What the golden ratio face test measures

Facemap takes one clearly defined pairing, so the number is repeatable and easy to check.

• /Face height: top of the forehead (landmark 10) to the chin (landmark 152)
• /Face width: across the cheekbones (landmarks 234 and 454)
• /Ratio: face height divided by face width
• /Score: how close that ratio sits to 1.618

Does the golden ratio actually predict attractiveness?

The evidence is far weaker than the popular framing suggests. Phi is a convention inherited from classical art, and studies testing it against rated attractiveness produce mixed results. Facemap reports it because it is an interpretable, repeatable way to describe proportion, and it sits alongside 21 other measurements rather than standing in for all of them.

Golden ratio versus your other proportion scores

The golden ratio overlaps with facial thirds, facial width-to-height ratio and face shape. If your ratio sits away from 1.618, those readings show which part of the face is driving it, which is more useful than a single figure.

The golden ratio formula, step by step

The calculation is simple enough to check by hand.

• /Measure face height from the top of the forehead to the chin
• /Measure face width across the cheekbones
• /Divide height by width
• /Compare the result with phi, about 1.618
