Paired landmarks
Compares horizontal distance from the facial midline and vertical alignment for matched left-right points.
Face Symmetry Test
Upload a photo and see how paired landmarks compare across the eyes, brows, nose, mouth and jaw. It is analysed in your browser and never leaves your device. The result corrects for eye-line rotation and reports regional evidence instead of mirroring half a face.
Analyze a photo →Measure visible symmetry
Upload a front-facing photo. It is analysed in this browser and never uploaded; the first run loads a local face-landmark model.
Photo stays in this browser
Choose one clear adult portrait
Front-facing, neutral expression, even light. JPG, PNG, WebP, HEIC or HEIF up to 10 MB.

Before you analyze
- 1Use your own photo, or one you have permission to use.
- 2One adult face only. No minors or age estimation.
- 3Results describe this photo, not objective beauty or health.
A typical first run loads about 15 MB of model/runtime files, then the browser caches them. Nothing is submitted to our analysis API.

The first run can take a moment. Your photo remains on this device.
We could not analyze this photo
Your photo and landmarks stay in page memory and are cleared when you reset or leave. Face-shape tools keep a small result summary in this tab for up to 30 minutes so you can continue to hairstyles or glasses. Clear the result to remove it.
Read the regions before the symmetry score
The eyes, brows, nose, mouth and jaw have separate paired-landmark comparisons. One shifted mouth corner need not mean the rest of the face differs by the same amount. The overlay helps you check what the detector actually measured.
- Both sides visible
- Use a frontal photo with a neutral expression.
- Head rotation
- Eye-line alignment corrects roll, but cannot undo a head turn.
- Retake comparison
- Keep distance, framing and expression as consistent as possible.

Evidence behind this result
The output is built from inspectable photo geometry and a separate image-quality signal.
Five regions
Separates the eyes, brows, nose, mouth and jaw so one area cannot hide another.
Pose signal
Uses the eye line and nose offset to flag roll or yaw that can distort the estimate.
How this tool works
1. Detect
A browser-based model finds one face and its visible landmark coordinates.
2. Align
The eye line defines a rotated coordinate system for left-right comparisons.
3. Compare
Normalised regional differences become an explainable 0–100 geometry score.
What the result cannot tell you
01
Expression, lens distortion, lighting and head rotation can change apparent symmetry.
02
Human faces are naturally asymmetric; a higher score is not a health or beauty diagnosis.
03
The tool measures a single two-dimensional photo, not bone structure or three-dimensional anatomy.
About this tool
How local processing works →Is a perfectly symmetrical face the goal?+
No. Natural asymmetry is normal and can be visually distinctive. This tool only describes visible paired geometry in one photo.
Why does my score change between photos?+
Camera distance, head angle, expression and lighting move visible landmarks. Use the same neutral, front-facing setup for comparison.
Does the test upload my photo?+
No. You choose a photo, but it is never sent anywhere: the tool loads its model into your browser and performs the measurement on your device.
