Free Face Symmetry Test: AI 68-Landmark Facial Symmetry Checker

68-Landmark Face Analysis

Upload one photo and the model places 68 landmarks on your face, measuring seven feature pairs against your midline to produce a single symmetry score. The process is landmark detection followed by arithmetic — no black box.

Get a clear numerical symmetry score based on precise facial landmarks.

Seven-Pair Breakdown

Instead of a single verdict, each of the seven pairs — eyes, eyebrows, ears, nose, mouth, upper cheeks, and lower cheeks — is scored individually. You can see exactly which part of your face carries the difference.

Understand which facial features are most asymmetrical.

Photo Never Stored

Your photo is measured and discarded immediately. It is never written to a database, and no account is required to use the tool. The site explicitly states: 'Your photo is measured and discarded. It is never written to a database.'

Use the tool with complete privacy — no storage, no account.

Free & Unlimited Use

The facial symmetry check is completely free. There is no mention of usage limits or paid tiers, and the FAQ confirms it's free. You can use it as often as you like.

Run unlimited symmetry checks at no cost.

Photo Quality Guidance

The tool provides clear instructions for getting a clean read: flat even light, square to the camera, plain background, and nothing across your face. These four factors move the score more than anything else.

Achieve the most accurate symmetry score by following simple photo tips.

Score Meaning Explained

Scores are explained in plain language: 95–100 means differences are smaller than photo noise; 88–95 shows small even differences; 80–88 indicates one or two pairs off midline; below 80 suggests a genuinely asymmetric feature or a difficult photo.

Know exactly what your score means and how to interpret it.

• Simple, focused functionalityFaceSymAI does one thing—facial symmetry analysis—and does it without feature bloat, making it easy to evaluate and integrate.
• API-first design for developersThe API architecture means engineering teams can integrate symmetry scoring into existing applications without building custom computer vision models.
• Privacy-conscious processingThe no-permanent-storage policy addresses a real concern for brands handling customer facial images, simplifying compliance discussions.
• Free tier for evaluationThe free plan allows businesses to test accuracy and output quality before committing to a paid subscription.

• Narrow use case limits broad adoptionThe tool solves a specific problem that only matters to businesses where facial symmetry directly impacts product recommendations or customer experience.
• Accuracy depends on image qualityAnalysis results vary significantly based on lighting, angle, and image resolution, which can lead to inconsistent scoring in uncontrolled user uploads.
• No built-in product recommendation engineFaceSymAI provides symmetry data but does not include a recommendation engine—brands must build their own logic to connect scores to products.
• Limited competitive differentiationSeveral computer vision APIs offer facial analysis features, and FaceSymAI's symmetry-specific focus may not justify a separate integration for teams already using broader platforms.

Check how symmetrical your face is from one photo

Upload a single JPG or PNG of one face looking straight at the camera. FaceSymAI places 68 landmarks, draws a vertical midline, and measures seven feature pairs — eyes, eyebrows, ears, nose, mouth, upper cheek and lower cheek — against that line. The average of the seven pair scores is your overall number. No account is needed, and the photo is measured and discarded rather than stored.

See which specific feature carries the difference

Instead of a single verdict, each of the seven pairs is scored on its own, so you can see where the difference sits. Eyes are scored on corner positions and how level they sit relative to the midline; eyebrows on height and arch; ears on distance from the centre line; nose on whether the bridge and nostrils track the midline; mouth on corner heights and lip-half width; and the upper and lower cheeks on face width at cheekbone and jaw height.

Get a clean read before trusting the number

The measurement is only as good as the photo. Face a window or a lamp for flat, even light, keep your head level with eyes on the lens, use a plain background, and push hair back and remove glasses and hats. Anything covering one side is measured as part of that side. If your score lands below 80, the site itself suggests shooting again with flat light and a level head before reading anything into it.

Interpret your score in context, not as a ranking

The score describes one photograph, not your face, and is not a ranking against anyone else. 95 to 100 means differences are smaller than the noise in an ordinary photo; 88 to 95 means small, evenly spread differences; 80 to 88 means one or two pairs sit clearly off the midline; below 80 may be a genuinely asymmetric feature or a difficult photo. Perfectly symmetrical faces are essentially nonexistent, and the small differences are most of what makes a face recognisable. If you are exploring other photo-based facial analysis tools, you could compare results with Face Shape Detector or EyeShapeAI.
