What the Test Measures

Our tool compares both halves of your face across six key metrics.

Eye Alignment

Measures the horizontal level and height of both eyes to check for vertical asymmetry.

Midline Deviation

Checks whether your nose tip and chin align along the facial vertical midline.

Jaw Balance

Compares jaw angle and width on the left vs. right to detect mandibular asymmetry.

Brow Height

Analyzes the distance from each brow to the hairline for left-right consistency.

Cheek Fullness

Evaluates the volume distribution across both cheeks in the mid-face region.

Lip Symmetry

Checks the horizontal balance of your upper Cupid's bow and lower lip corners.

Frequently Asked Questions

What is a face symmetry test? +
A face symmetry test measures how evenly balanced your facial features are across the vertical midline. Our tool compares the left and right halves of your face and produces a symmetry score from 0–100%.
Is perfect facial symmetry attractive? +
Research suggests moderate symmetry is associated with attractiveness, but perfectly symmetrical faces can appear unnatural. Most people have slight natural asymmetry that adds character.
Does the test upload my photo? +
No. All analysis runs entirely in your browser using JavaScript. Your photo is never sent to any server — we have no way to access it.
What causes facial asymmetry? +
Facial asymmetry is extremely common and caused by genetics, sleeping position, jaw use patterns, and muscle dominance. Mild asymmetry is completely normal.
