Facial Symmetry Test: How to Read Your Results
A facial symmetry test compares corresponding landmarks across the two sides of a face. The useful result is a measurement you can understand—not just a number with no explanation.
What does facial symmetry measure?
Look Maximize places facial landmarks on a front-facing camera photo. It aligns the eye-center line, then compares six regions: eyes, nose, mouth, cheeks, jaw, and chin. Each region contributes a mirror difference relative to face width.
The final symmetry measurement combines those regions with a root-mean-square calculation. Larger individual differences therefore contribute more than they would in a simple average. Eye-corner pairs share one region, so the eyes do not count twice.
Symmetry error = RMS of regional mirror differences ÷ face width
Reading the symmetry bar
The marker is your measured error. The highlighted band is the app’s comparison range. For symmetry, a lower error means the photographed landmarks sit closer to their mirrored positions. A value shown as 1% is a normalized landmark difference, not “99% attractive.”
The same symmetry reference applies to both scoring presets. Other proportions can use different references, which is why a preset can change the overall score without changing your symmetry measurement.
Why a selfie can look uneven
An angled head changes a two-dimensional projection. Turning slightly makes the nearer side appear different from the farther side; tilting introduces another source of change. The scanner aligns in-plane roll, but it cannot undo every perspective effect.
Expression also matters. A raised eyebrow, an uneven smile, or hair across an eye can move or hide the landmarks. These are reasons to compare like-for-like scans rather than interpret every small difference as a change to your face.
- Face the camera directly, with it near eye level.
- Use an even expression with relaxed brows and mouth.
- Keep the same camera and a similar distance for comparisons.
- Compare the individual regions as well as the overall measurement.
Symmetry is one part of the report
Your report also contains eye spacing, nose and mouth proportions, brow measurements, and a confirmed forehead measurement when available. The additional regional descriptors help explain a symmetry result without adding a second attractiveness score.
A symmetry test cannot identify the cause of an apparent difference or diagnose a skeletal condition. Read the methodology for the exact calculation, then use your result as a description of the captured photo.
