Face Symmetry Test

How we measure facial symmetry

1. We fit a line through 21 points down the center of your face (forehead, nose bridge, nose tip, lips, chin).
2. For each pair of matching points, we mirror the right-side point across that line and measure how far it lands from its left-side partner.
3. Distances are measured in units of your interpupillary distance, so the score doesn't depend on photo size.
4. Smaller average distance = higher score.

What's a normal symmetry score?

No face is perfectly symmetrical. In straight-on photos, most faces score between 80 and 92. Scores drop sharply if your head is turned even slightly, so a low score usually means the photo was taken at an angle. Try again facing the camera directly.

Is symmetry attractive?

Studies have found a modest link between symmetry and perceived attractiveness, but it's only one factor among many, and small asymmetries make faces look natural. See our attractiveness test for a broader, just-for-fun score.

How to take the right photo

• Face the camera straight on. Turning your head shrinks one side of your face and skews every ratio.
• Keep your chin level. Tilting up makes the face look shorter; tilting down makes the jaw look narrower.
• Pull your hair back so your hairline, forehead and jaw are visible.
• Use even, front-facing light. Window light is ideal. Avoid strong side shadows.
• Neutral expression, mouth closed. Smiling widens the cheeks and changes the jaw.
• Hold the camera at eye level, about an arm's length away. Close-up selfies distort the face (the nose looks bigger and the face narrower).
