See the two mirrored halves
These are constructed pictures, not your real face or predicted changes. Each half is reflected across the same tilted center line used in the measurement. Blank edges are outside the original photo.
How to check your facial symmetry
- Take a straight-on photo. Keep the camera at eye level, your head upright and your expression relaxed. Include your whole face and leave room around it.
- Accept the photo-analysis notice and choose the image. The tool finds landmarks automatically. It rejects an image when no face or more than one face is detected.
- Check the overlay. Look at the eye, nose, mouth and jaw points. If a point misses its feature, retake the photo. Detection does not guarantee a correct measurement.
- Read the seven rows. Each row shows the two measured distances, their difference relative to face width, and the custom component score. Save a text summary only if you want one.
A close selfie, head turn, raised eyebrow, smile or partly covered cheek can change the reading. This method accounts for the center line’s tilt within the picture; it cannot undo perspective or recover a three-dimensional face.
What does a facial symmetry score mean?
There is no validated “normal score” for this calculator. We do not label 80, 90 or 95 as typical, healthy or attractive. A different tool may use different points, weights and formulas, so its number is not directly comparable.
Small changes between repeated photos can reflect camera position or landmark placement. This is an educational comparison, not a clinical assessment or a reason to change your appearance. A symmetrical image can score highly while still having distorted or misplaced landmarks.
Exactly what the tool measures
Method 2.0 uses seven comparisons across five regions: brows, eyes, mid-face, mouth and jaw. Pixel coordinates are used before any distance is calculated: horizontal coordinates are multiplied by image width, and vertical coordinates by image height. This avoids treating a tall photo as a square.
| Comparison | Measurement |
|---|---|
| Brow height | Position along the center axis, relative to its upper point |
| Eye opening | Distance between selected upper and lower eyelid points |
| Outer-eye distance | Perpendicular distance from each outer eye corner to the center axis |
| Cheek distance | Perpendicular distance from each selected cheek point to the axis |
| Nose-side distance | Perpendicular distance from selected nose-side points to the axis; not a measurement inside the nostril |
| Mouth-corner height | Position along the center axis, relative to its upper point |
| Jaw distance | Perpendicular distance from selected jaw points to the axis |
The estimated axis joins MediaPipe points 168 and 152. Face width is the straight distance between cheek points 234 and 454. These model points approximate visible features; they do not directly measure the skull.
For each row: gap = |left − right| ÷ face width.
Component = max(0, 100 − 500 × gap).
Overall = mean of all seven unrounded components, displayed to one decimal place.
The multiplier 500 is our design choice, not a scientific constant. If two distances differ by 4 pixels and face width is 200 pixels, the gap is 2% and the component is 90/100. Each of the seven rows has equal weight; regions are not averaged separately. Method 2.0 results should not be compared directly with this page’s earlier method.
What this test cannot tell you
The tool has not been validated against professional measurements or an independent population dataset. We cannot state a measured accuracy percentage, a universal average, or a separate benchmark for men, women, people in the USA or people in India.
Landmark detection and symmetry scoring are different steps. MediaPipe estimates feature positions; this site’s published formula compares selected distances. Neither step establishes attractiveness, age, health, personality or identity.
A blocked model download, unsupported browser, unreadable file or unclear image can prevent analysis. The tool shows an explanation rather than substituting a questionnaire score. Try a current browser and a clear portrait. If you have a health concern, do not use this result to decide what it means.
Photos, camera and privacy
Your image is processed in this browser. This widget does not upload the photo, send the result to analytics, create an account or store a remote result. Clearing the tool removes its active image and result; downloading creates a file on your device.
Automatic analysis downloads MediaPipe code from jsDelivr and a model from Google storage. Download providers receive ordinary request information. MediaPipe also sends performance and usage metrics to Google; its official privacy notice distinguishes those metrics from the input image. Acceptance is required before this widget starts photo analysis. Unticking the checkbox stops active analysis and clears the result, but cannot recall metrics already sent.
Camera access requires your permission. It ends after capture, when you stop or clear it, when you choose an uploaded image, or when the page becomes hidden. This widget does not record video. Website-wide analytics and cookies are covered by the site privacy policy.
Face symmetry test questions
Is my face symmetrical?
This tool can show differences between selected points in one photo. It cannot establish a complete, permanent description of a three-dimensional face. Check the overlay and the individual measurements before interpreting the number.
Is 90 a good facial symmetry score?
Under this formula, 90 means the seven selected differences average 2% of the measured face width, provided none of the component scores has been clipped at zero. It does not mean 90% accuracy or that you rank above 90% of people.
Can a mirror or filter check symmetry?
A mirror can help you notice visible differences. A filter that duplicates one side creates a new image; it does not measure your actual face. The mirrored pictures here are illustrations, separate from the numerical comparison.
Why did another photo give a different result?
Camera distance, angle, expression, lighting and automatic point placement can all change measured distances. Keep the setup consistent. This tool does not establish whether a difference between photos is a real physical change.
Can I check symmetry without uploading to a server?
Yes. The photo is analyzed on your device. The model and software still require network downloads and MediaPipe sends usage metrics as explained above.
Is this a golden ratio or face shape test?
No. Symmetry compares two sides. Golden-ratio tools compare selected distances with 1.618, while face-shape tools estimate outline categories. These are different tasks.
Explore the right next step
Estimate your face shape for outline categories, use the golden ratio face calculator for three proportion comparisons, or read facial thirds and fifths for a diagram of vertical and horizontal divisions.
