The human face is roughly divided into three vertical sections – forehead, nose, and chin. Your face shape is determined by the proportions of these sections. There are seven primary face shapes: oval, oblong, square, round, base-down triangle, base-up triangle, and diamond. To find your face shape, look into a mirror and pull your hair back so you can see your face clearly. Then, trace the outline of your face with a lip or eyebrow pencil.
Oval: Face is slightly longer than wide, and forehead is larger than chin.
Oblong: Face is longer than wide, and forehead, cheekbones, and jaw are about the same width.
Square: All measurements are about equal. Jaw is slightly wider than cheekbones, and forehead is slightly wider than jaw.
Round: Face is as long as it is wide, and cheekbones and jaw are about the same width.
Base-Down Triangle: Face is wider at the jaw than at the forehead, and chin is pointed.
Base-Up Triangle: Face is wider at the forehead than at the jaw, and chin is rounded.
Diamond: Face is narrow at the forehead and chin, and cheekbones are the widest part of the face.
