Face analysis

Facial symmetry: do you need a perfectly symmetrical face?

No face is perfectly symmetrical. Small differences between the left and right sides are normal and go unnoticed day to day. Studies link slightly higher symmetry to slightly higher perceived attractiveness, but the effect is modest next to balanced proportions and skin. 📏

Why symmetry appeals

Several studies show that, all else equal, a slightly more symmetrical version of a face is rated slightly more attractive. The effect exists, but it is modest: small asymmetries are natural and go unnoticed. Perfectly symmetrical computer-generated faces often look artificial.

The golden ratio: a stubborn myth

The golden ratio (1.618) is often said to be the key to the ideal face. Recent studies find no strong link between that exact ratio and perceived beauty. Balanced proportions matter more:

• The three thirds of the face (forehead, nose, lower face) of similar height.
• Eye width close to the distance between the eyes.
• A balanced face width-to-height ratio.
• A chin and nose that fit the profile.

Asymmetries you can correct

Many visible asymmetries don't come from the bones:

• Brows of different shape or height: tweezing or reshaping evens them out.
• A hair part always on the same side, or an uneven beard.
• Always chewing on one side, or always sleeping on the same cheek.
• A tilted head posture.
• A difference in skin or dark circles on one side.

How to measure your symmetry

Mirrors and selfies mislead: the front camera flips the image and distorts features close to the lens. A straight-on photo taken from 1.5 m (about 5 ft), head level, is the starting point. The GlowUpTogether scan places landmarks on your photo and compares the two halves of your face: eyes, brows, nose, mouth, jaw. 📸

What our measurements show

None of the 78 adult faces we measured is perfectly symmetrical. The median gap between a point on the face and the mirror image of its counterpart is 3.8% of the distance between the pupils, ranging from 2% to 7%.

The eyes are the most symmetrical area (1.9% median) and the cheeks the least (5.4%): the cheeks are the most asymmetrical area in 47 of 78 faces. A small asymmetry is normal.

Measured on November 3, 2026 by the GlowUpTogether engine on 78 compliant front-facing photos (out of 102) from the Face Research Lab London Set (DeBruine and Jones, CC BY 4.0 license): 34 women and 44 men, median age 25. Method and limits (in French).

Frequently asked questions

Is an asymmetrical face less attractive?

Not necessarily. Slight asymmetry is universal and often invisible. Balanced proportions and skin quality weigh at least as much.

Does the golden ratio for faces exist?

The ratio exists in mathematics, but research does not confirm that it defines facial beauty. It is better to look at the overall balance of proportions.

Can you make your face more symmetrical?

Yes, to a good extent: brows, beard, haircut, posture and skin. For the rest, minimally invasive options are something to discuss with a doctor; GlowUpTogether never recommends surgery. 🩺
