The 7 Face Shapes
Seven categories, one shared rule set. Every page below quotes the same measurements the detector uses.
An oval face is noticeably longer than it is wide, with the cheekbones as the widest point and a jawline that curves rather than angles. The forehead sits slightly narrower than the cheekbones and the jaw slightly narrower again, so the outline tapers gently at both ends.
A round face is about as wide as it is long, with full cheeks, a soft jawline and no sharp corner at the jaw. The cheekbones and face length sit close to equal, which is what gives the outline its circular read.
A square face is about as wide as it is long, like a round face, but the jaw is the giveaway: a strong, wide jaw with a distinct corner below the ear and a flat chin line. Forehead, cheekbones and jaw all sit close to the same width.
An oblong face is the long version of a square: clearly longer than it is wide, with forehead, cheekbones and jaw all close to the same width and a jawline that turns at a corner rather than curving.
A heart face is widest at the forehead and narrows steadily to a pointed chin. The cheekbones sit between the two, and the jaw tapers sharply, which is what produces the characteristic heart outline.
A diamond face is widest at the cheekbones with both the forehead and the jaw clearly narrower, tapering to a pointed chin. It is the rarest of the seven outlines and the easiest to confuse with heart, since both end in a point.
A triangle face is the inverse of heart: the jaw is the widest point, the forehead the narrowest, and the outline broadens steadily from top to bottom. It is sometimes called pear-shaped.
