What does a facial symmetry test measure?

It compares the left and right halves of your face by mirroring your facial landmarks across a midline and measuring how far the two sides differ. A higher score means the two halves match more closely.

Is a perfectly symmetrical face normal?

No. Every real face has some asymmetry, and small differences are completely normal. The score describes your photo, not your attractiveness.

What are the proportion measurements?

Five ratios between features, such as the middle to lower face, upper lip to chin, and the spacing of the eyes. Each is shown against a commonly cited reference range for context, not as an ideal.

Why does a turned head change the result?

Symmetry is only meaningful in a straight-on photo. If your head is turned or tilted, the two sides look different because of the angle, so the tool warns you and corrects for tilt where it can.

What we measure

Middle-to-lower face

Often cited as roughly 1 : 1

Compares the height from the brow line to the nose base with the height from the nose base to the chin.

Eye spacing and fifths

Often cited as about one eye-width apart

Measures the gap between the eyes and each eye’s width relative to the width of the face.

Bilateral symmetry

No face is perfectly symmetrical

Mirrors the left half of your face onto the right and checks how far matching landmarks land from each other.

Face length vs. width

Typically about 0.75 to 0.95

Brow-to-chin height divided by face width, a simple indicator of a longer or wider face shape.

What Face Balance measures

The tool finds 68 landmark points on your face, levels any head tilt, and calculates two things: how closely the left and right halves of your face mirror each other, and five proportions between your features. Everything is calculated in your browser, so your photo is not uploaded.

How to read your results

Symmetry score: a description of this photo. Small differences between the sides are normal, and lighting and angle affect the score.
Proportions: each ratio is shown next to a common reference range. Being outside a range is common variation, not a flaw.
Overlay: the landmark points and guide lines let you see exactly what was measured.

For a reliable reading use a straight-on, evenly lit photo with your hair off your forehead. You can also try the free face age calculator or find your face shape.
