Quick Summary

Proportion, in art and mathematics, refers to the relationship between the sizes of different parts of a whole, or between the parts and the whole itself. This concept is crucial for creating visually pleasing and harmonious compositions.

In art, proportion can be achieved through various principles of design, such as balance and symmetry. The Golden Mean, or Golden Ratio, is an aesthetically satisfying proportion, approximately 1.618, that has been used since ancient times to guide the framework of lines and shapes in paintings and sculptures.1

Mathematically, the golden ratio is an irrational number defined by a specific division of a line segment. It is closely linked to the Fibonacci sequence, where the ratio of successive numbers approaches the golden ratio. This mathematical concept also appears in natural patterns and has been applied in design and architecture.2
