Face Symmetry Test
This free face symmetry test measures how closely the left and right halves of your face mirror each other. Upload a front-facing photo and an on-device AI model maps a 478-point 3D face mesh, draws a midline through your nose bridge and chin, then compares nine paired points — eye corners, brow ends, nostrils, mouth corners, and three points along each side of the jaw — on both sides of that line.
About the Face Symmetry Test
You get a symmetry percentage and a 0–100 symmetry score, alongside a complete facial harmony report covering proportions, jawline, cheekbones, and eye spacing. No face is perfectly symmetric: research on facial measurement consistently finds mild asymmetry in essentially everyone, and typical faces land around 90–98% mirror alignment on landmark-based tests like this one. A lower score is not a flaw — it is usually invisible in person and only noticeable in perfectly frontal photos.
Everything runs inside your browser. Your photo is never uploaded, stored, or transmitted — close the tab and it is gone.
This test is part of Calqora's full Face Analysis tool — the same photo also gives you scores for every other category, so you get the complete picture, not just one number.
How We Calculate Your Score
No black box: your Harmony Score is a weighted composite of five measurable categories, each computed from a 478-point 3D face mesh detected on your device. The feature-by-feature breakdown of your eyes, eyebrows, nose, and lips shown with the report is descriptive detail — it does not feed into the score.
Facial Symmetry
weight 25%
A midline is drawn through your nose bridge and chin, then 9 landmark pairs (eye corners, brow ends, nostrils, mouth corners, jaw contour) are compared across it — both horizontal distance and vertical height.
Facial Thirds & Proportions
weight 25%
Your face is split into vertical thirds (hairline→brow, brow→nose base, nose base→chin) and scored on how evenly they divide (60%), plus your face length ÷ cheekbone width against the classical 1.618 golden-ratio reference (40%).
Eye Spacing & Canthal Tilt
weight 20%
The distance between your inner eye corners is compared to the width of one eye (the classical rule of fifths), and the angle from outer to inner eye corner measures canthal tilt.
Jawline Definition
weight 15%
Jaw width ÷ cheekbone width measures taper (60%), and the angle formed at your chin between the left and right jaw contours measures chin definition (40%).
Cheekbone Prominence
weight 15%
Cheekbone width ÷ jaw width (60%) and cheekbone width ÷ face length (40%) measure how strongly the midface projects relative to the lower face.

Frequently Asked Questions
How does the face symmetry test measure symmetry?
The AI maps a 478-point 3D mesh on your face, draws a vertical midline through the nose bridge and chin, and compares nine landmark pairs (eye corners, brow ends, nostrils, mouth corners, and jaw contour points) on each side. It measures both horizontal distance from the midline and vertical height differences, then combines them into a symmetry percentage and a 0–100 score.
What is a normal face symmetry score?
Almost everyone lands between roughly 90% and 98% mirror alignment. Perfect 100% symmetry essentially doesn't exist in real faces — even faces widely considered very attractive measure with mild asymmetry. Differences below about 3–4% are generally invisible in everyday life.
Does camera angle affect my symmetry result?
Yes, strongly. Even a few degrees of head rotation shifts one side of the face closer to the camera and reads as asymmetry. For an accurate result, face the camera dead-on, keep the phone at eye level, use even lighting, and avoid wide-angle front cameras held close to the face, which distort the nose and cheeks.
Can I improve my facial symmetry?
Bone-level symmetry is fixed, but perceived symmetry responds to styling: brow grooming can even out brow height, hairstyles with a side part de-emphasize a dominant side, and consistent posture and sleeping position affect soft-tissue puffiness. This tool's report includes styling suggestions matched to your result — it does not recommend any cosmetic procedures.
Is my photo private?
Yes. The symmetry test runs entirely in your browser using on-device AI (Google's MediaPipe Face Landmarker, self-hosted). Your photo never leaves your device, nothing is stored, and no account is required.
