Facial symmetry test: how symmetrical is your face?
Take or upload one front-facing selfie. The facial symmetry test finds the midline of your face, compares six regions left to right and gives you a symmetry score out of 100, with your two half-face mirror images. Your photo stays in your browser.

01What the facial symmetry test measures
Six regions, each compared through a pair of points on either side of your face. The test measures how far each point sits from the midline and how much the two sides differ.
- Eyes
- Outer and inner eye corners
- Brows
- Outer and inner brow ends
- Nose
- The sides of the nose and the nostril edges
- Mouth
- Mouth corners and the peaks of the upper lip
- Cheeks
- The widest points of the cheekbones
- Jaw
- Jaw corners and the lower jaw line
Example: the facial midline and the eye points
02How to read your facial symmetry score
Each region starts at 100 and loses points for every 1% of face width by which one side sits further from the midline than the other. Your facial symmetry score is the average of the six regions, and it is the same symmetry part that goes into the free attractiveness test. No face is perfectly symmetrical: most faces in our reference set differ by 0.33% to 0.69% of face width on average, and your result tells you whether yours is below, inside or above that range.
03Half-face images: left + left and right + right
The facial symmetry test turns your photo so the midline is straight, then mirrors each half onto the other. The two images show your face as if both sides matched its left or its right half. Mirroring doubles any difference, so they look more different from each other than your two sides really are: treat them as a curiosity, not a verdict.
04How to take the photo
- 01Face the camera straight on, with the phone at eye level. Even a slight turn makes the far side look narrower.
- 02Use even light from the front, such as facing a window. A shadow on one side moves the points the test finds.
- 03Keep a neutral expression with your mouth closed: a smile is rarely even.
- 04Pull your hair back off your forehead and the sides of your face, and take off your glasses.
- 05Hold the phone at arm's length. Very close photos stretch the middle of the face.
05How the facial symmetry test works, and its limits
Your browser finds 478 points on your face, fits the midline through the forehead, nose and chin, and measures how far each pair of points sits from it. Left and right are as seen in the photo, not your own left and right. A head turn makes one side look narrower: the test takes out the part a small turn explains, but not all of it, so a straight-on photo matters most. Light, hair over the face and expression also shift the points. Symmetry is one measurement, not a verdict on how you look.
06Facial symmetry questions
01How do I test my facial symmetry?
Take one straight-on selfie in even light, with a neutral expression and your hair off your face. The facial symmetry test finds the midline of your face, compares your eyes, brows, nose, mouth, cheeks and jaw left to right, and gives each a score out of 100.
02What is a good facial symmetry score?
There is no pass mark. Most faces in our reference set differ by 0.33% to 0.69% of face width on average across the six regions, and your result says whether you are below, inside or above that range. A higher score means the two sides are closer to mirror images.
03Is anyone's face perfectly symmetrical?
No. Every face has small left–right differences, and the two sides also move differently when you talk or smile. That is why the test asks for a neutral expression and compares the sides in a still photo.
04Why do my two half-face images look so different?
Mirroring doubles any difference between your two sides. A small head turn or light from one side also makes one half look wider. Retake the photo straight on in even light to compare.
05Does facial symmetry affect attractiveness?
In our free attractiveness test it is one of four parts: this symmetry score sits alongside facial thirds, fifths and face length to width. Symmetry alone doesn't decide how attractive a face looks.
06Is my photo uploaded?
No. The facial symmetry test runs entirely in your browser and never uploads your photo or the points found on your face.
