Facial Symmetry Test

Facial symmetry has long been studied as a component of perceived attractiveness. Research in evolutionary psychology suggests that symmetric faces may signal developmental stability, though the relationship between symmetry and actual attractiveness is more nuanced than popular media suggests.

Our AI-powered symmetry analysis uses MediaPipe Face Mesh to map 468 three-dimensional landmarks across your face. By comparing corresponding points on the left and right sides — from the corners of your eyes to the edges of your jawline — we calculate a precise symmetry score.

The analysis measures several types of symmetry: horizontal symmetry (how well your left and right sides mirror each other), vertical alignment (whether features like your eyes and mouth sit level), and midline deviation (whether your nose and chin align with your facial center).

Perfect symmetry is essentially nonexistent in human faces. Most people have naturally asymmetric features — one eye slightly higher, one cheek slightly fuller. Research from the University of Louisville found that the most attractive faces typically score around 95-97% symmetric, not 100%. Small asymmetries can actually add character and individuality.

Factors that affect facial symmetry include genetics, sleeping position, dental alignment, and jaw muscle development. Some aspects of symmetry can be influenced through posture correction, dental work, or skincare routines that treat both sides of the face equally.
