If you have a square face, the sides of your face are straight and your jawline is slightly angled with a very minimal curve. Your face is nearly as wide as it is long. In other words, if you were to measure from the edge of your temple to the top of where your jawline starts, you'd find that it would be approximately the same as the distance from your left jaw to right jaw.

If someone drew lines connecting the centre of your hairline to your cheekbones and down to your chin, it would create a diamond shape—hence, the name. Diamond-faced women have pointed chins and high cheekbones. The main difference between a diamond-shaped face and a heart-shaped face is the hairline—if you have a diamond-shaped face, your hairline will be narrower.

Rectangular faces are sometimes called "oblong," and they're similar to a square-shaped face but longer than they are wide. Your forehead, cheeks and jawline are approximately the same width and your chin has a very slight curve.

If your chin is pointed and your forehead is the widest part of your face, you have a heart-shaped face. Some people may have a widow's peak at their hairline, but you can still have a heart-shaped face without one—picture an upside-down triangle instead.

A round face is just a square-shaped face with softer angles—the sides of your face curve slightly outwards instead of being straight. Your chin is rounded and your cheekbones are the widest part of your face.

Ladies with oval faces will have a forehead that is only a tiny bit wider than their curved chin—picture an egg placed upside down. Your face is similar to an oblong face, but with a softer chin and more curve to the sides of your face.
