Principle of Proportion
Proportion is the relationship of two or more elements in a design and how they compare with one another. Proportion is said to be harmonious when a correct relationship exists between the elements with respect to size or quantity.
Good proportion adds harmony, symmetry, or balance among the parts of a design.
The effective use of proportion in design is often referred to as harmony, a relationship in which the various elements of the composition appear as if they belong together in size and distribution.
For example, if one figure is made to look larger compared to other figures in a composition, it is said to be out of proportion and is given greater importance.
