Which design principle focuses on the aesthetic balance of a product?

The design principle that focuses on the aesthetic balance of a product is symmetry. Symmetry relates to balanced proportions where elements are arranged in a way that is visually appealing and harmonious. It can create a sense of order and stability in a design, often leading to a more aesthetically pleasing product. Symmetrical designs are frequently used in architecture, product design, and graphic design to achieve a clean and organized appearance.

In contrast, other design principles like unity emphasize the overall cohesion of design elements, ensuring they work together as a whole. Emphasis involves highlighting specific components to draw attention, while proportion refers to the scale and size relationships between different elements. While those principles are important in their own right, they do not specifically focus on creating aesthetic balance in the same way that symmetry does.
