What the symmetry test measures
Our AI analyzes multiple dimensions of facial balance alongside expression quality.
Left-Right Balance
Measures how closely the left and right sides of your face mirror each other — eye alignment, cheekbone position, jaw symmetry.
Facial Proportions
Analyzes the proportional relationships between your facial features — spacing between eyes, nose-to-chin ratio, facial thirds.
Smile Symmetry
Checks whether your smile is balanced — asymmetric smiles often indicate a forced expression, while balanced smiles signal genuineness.
Eye & Brow Alignment
Measures the alignment of your eyes and eyebrows. Even small differences in eye height or brow position affect perceived symmetry.
What science says about facial symmetry
Research across multiple cultures shows that facial symmetry is consistently rated as attractive — it's one of the most universal beauty signals. Evolutionary biologists believe this is because symmetry signals developmental health and genetic fitness.
However, the research also shows something important: no face is perfectly symmetrical. Everyone has asymmetries. Studies found that even faces rated as highly attractive typically have measurable left-right differences.
What matters more in real-world contexts — dating apps, LinkedIn, social media — is expression quality. A slightly asymmetrical face with a genuine, warm smile consistently outperforms a more symmetrical face with a forced or neutral expression.
That's why RealSmile measures both symmetry and expression. Your symmetry score tells you about your photo's balance. Your expression score tells you about its impact.
How to improve facial symmetry in photos
You can't change your bone structure, but you can dramatically improve how symmetrical you look in photos.
Face the camera directly
Even a slight head tilt creates asymmetry in photos. Face the lens straight-on for the most balanced result. Use your phone's grid lines to align.
Use even lighting
Uneven lighting creates shadows that make one side of your face look different from the other. Soft light from directly in front of you (like a window) creates the most symmetrical look.
Camera at eye level
Looking up or down at the camera distorts facial proportions. Position your phone at exactly eye level for the most accurate, symmetrical framing.
Relax completely
Facial tension creates asymmetry — one eyebrow raised, mouth pulled to one side, jaw clenched. Take a deep breath and let every muscle in your face relax before shooting.

Upload a Front-Facing Photo
For best symmetry results, use a photo where you're looking directly at the camera with even lighting.
AI Maps Your Face
Our AI detects facial landmarks and measures left-right balance, proportions, and expression quality.
