Golden Ratio Face Test: Measure Your Facial Proportions

The golden ratio, written φ (phi), is about 1.618. Two lengths are in the golden ratio when the longer one is about 1.618 times the shorter one. It appears in geometry, art and architecture, and since the Renaissance people have looked for it in faces, proposing that features spaced in this ratio look especially harmonious.

The evidence for that claim is mixed. Studies that measure real faces find many attractive faces that do not follow φ, and ideal proportions vary by age, sex and ancestry. The ratio is best treated as one historical reference point for describing proportions, not as a beauty standard. This calculator shows how close your measurements come to it so you can explore your proportions, not to grade your face.

Each ratio divides a longer facial distance by a shorter one, using landmarks found by MediaPipe Face Landmarker in your browser. The match for each ratio is 100% at exactly 1.618 and falls by 2 percentage points for every 1% the ratio differs from φ, down to 0%. Your overall golden ratio match is the average of the four.

Alongside φ, artists use two simpler proportion guides. The facial thirds divide the face vertically into three bands: hairline to brows, brows to the base of the nose, and nose to chin. Classically each band is one third of the face. The facial fifths divide the width of the face into five eye-widths: each eye, the gap between the eyes, and the two outer sides.

Your result shows both. Because a photo cannot reliably locate the hairline, the upper third here starts at the visible top of the face found by the landmark model. That makes the upper band read shorter than a hairline-based measurement, so focus on how your middle and lower thirds compare with each other. The fifths are measured along a path from cheek to outer eye corner, across both eyes and out to the other cheek.

Select any ratio in your result to draw it on your photo: the white line is the longer length and the orange line is the shorter one. A ratio below 1.618 means the shorter length is relatively large; above 1.618 means it is relatively small.

Few real faces match φ on every ratio. The face length to width ratio in particular usually reads below 1.618 in photos, partly because the visible top of the face sits below the hairline; the full face report's own reference for this ratio is 1.38. A lower match is not a flaw: plenty of striking faces sit far from φ on one or more ratios.

Proportions depend on distance, angle and expression, so use a consistent setup:

• Look straight at the camera with your chin level; tilting the head up or down changes every vertical ratio.
• Hold the camera at least an arm's length away. Close selfies enlarge the nose and mouth relative to the face width.
• Keep your mouth closed and relaxed; smiling widens the mouth and changes the mouth-to-nose ratio.
• Pull hair back so the cheekbones and forehead are visible.
• Compare results only between photos taken the same way.

Proportions are one part of how a face is perceived. Symmetry, measured by the Face Symmetry Test, compares the two halves of your face, and eye-corner angles are covered by the Canthal Tilt Calculator. The AI Attractiveness Test combines symmetry, thirds, fifths and face length to width into one geometry score.
