Every face shape is a width pattern — where your face is widest and how it tapers. Find yours below, or let the free Face Shape Detector classify it from one selfie.
Every classification comes down to four numbers from one straight-on photo: forehead width, cheekbone width, jaw width, and face length. The pattern of which is widest — and how length compares to width — places you in one of the seven shapes.
Widest at the cheekbones with gentle taper is oval; dramatic taper at both ends is diamond. Even widths top to bottom are square (short) or oblong (long). Widest at the forehead is heart; widest at the jaw is triangle; and roughly as wide as it is long with soft angles is round.
Borderline cases are common — plenty of faces sit between two shapes, and fullness or leanness can tip the read. That's exactly the case where a consistent AI measurement beats eyeballing your own reflection.
The free Face Shape Detector classifies your shape from one selfie — and the Symmetry IQ app renders a Face Shape view from your own 3D scan in the Symmetry Lab, alongside 8 tracked balance metrics.
The seven standard face shapes are oval, round, square, oblong (rectangular), heart, diamond and triangle (pear). Each is defined by a width pattern — where the face is widest between the forehead, cheekbones and jaw — combined with how long the face is relative to its width.
Take a straight-on photo with your hair pulled back, then compare three widths — forehead, cheekbones, jaw — and the face's overall length. Widest at the cheekbones with clear taper suggests oval or diamond; even widths suggest square or oblong; widest at the jaw is triangle; widest at the forehead is heart. Or upload the photo to the free Face Shape Detector and let the AI classify it.
The bone pattern is fixed in adulthood, but the visible shape shifts at the margins: leaning down reveals width structure that fullness hides, masseter growth from clenching can widen the jaw, and bloat rounds everything. That's why the same face can read round at one body composition and square at another.
No shape wins. Styling guides treat oval as the baseline because most conventions were designed around it, but every shape has strong examples — balance, symmetry and proportion within the shape matter far more than the shape's name.
