Facial proportions that reflect the Golden Ratio are also considered to be universally beautiful. The Golden Ratio, 1.618, is calculated from Fibonacci’s Sequence and observed in nature. Sunflower seed patterns, spiraled sea shells, and more famously, Da Vinci’s Vetruvian Man demonstrate this aesthetically pleasing ratio that is often utilized by architects and interior designers. Cosmetic surgeons apply this ratio to various measurements on the face. In the following images, each colored line is a golden section of the next. For example, the length of George Clooney’s face is 1.618 times the width with his eyes centered at the midpoint.
A facial diagram, called the Marquardt Mask, has been created based on the Golden Ratio to illustrate how certain faces that conform to these ratios are considered beautiful. It is important to recognize that even if faces conform to the same proportional measurements, variations in feature size, shapes, and colors allow for a wide array of cross-cultural beauty that varies with each individual.
