Both those distances match the population average, or are close to it. It should be just over one-third the height of her face. Just as important, they found, is the distance between a woman’s eyes and mouth. Researchers at the University of California, San Diego and the University of Toronto in Canada discovered that ratio. People find her most attractive when that distance is just under half of the width of the face. “Such as the size of the features of your face and their arrangement.”įor example, the distance between the centers of a woman’s eyes affects whether she is considered beautiful. “Averageness includes all kinds of factors,” says Little. And, in general, people find such faces quite attractive. Average, here, does not mean “so-so.” Rather, average faces are a mathematical average (or mean) of most people’s features. This averageness, Little points out, refers to how similar a face looks to most other faces in a population. “So,” he explains, “symmetry looks normal to us. In the end, many of these faces seem symmetrical.

Everyone’s face is slightly asymmetrical, but in different ways, he says. He is a psychologist at the University of Stirling in Scotland. “People’s faces usually only differ subtly in symmetry,” says Anthony Little. But our eyes read faces with similar proportions on both sides as symmetrical. In a symmetrical face, the left and right sides look like each other. Faces that we deem attractive tend to be symmetrical, they find. Researchers have begun turning up some answers, though. They also tend to have measurements similar to the population average. Attractive faces, such as this one, tend to be symmetrical. But few can say precisely why those faces seem so beautiful. Different people will usually agree on which faces those are. Looking at a set of photos, it’s easy to say which faces we find attractive.
