Why facial symmetry matters
Facial symmetry is one of the most studied factors in attractiveness research. Symmetrical faces are often perceived as healthier and more attractive. No face is perfectly symmetrical, but the closer your features mirror each other, the higher your symmetry score.
How the AI symmetry test works
Aesthetica detects landmarks on your eyes, brows, nose, lips and jaw, draws a vertical midline through your face and measures how far each feature deviates from its mirror position. These deviations are combined into your facial symmetry score.
Golden ratio face analysis
The golden ratio (about 1.618) has been linked to facial beauty for centuries. Aesthetica measures key ratios in your face — like face length to width, and the spacing between your eyes, nose and lips — and shows how close they are to ideal proportions.
- Face length to face width ratio
- Facial thirds: forehead, mid-face and lower face balance
- Eye spacing relative to face width
- Nose and lip width proportions
Symmetry is part of your full AI face rating
Your symmetry score and golden ratio analysis feed into your overall AI face rating, alongside face shape, skin, eye shape and hairline analysis — so you get the complete picture from a single selfie.
