The five principles of design are proportion, balance, rhythm, emphasis, and unity. Proportion refers to the size relationship between parts of a design and the whole. Balance can be formal/symmetrical or informal/asymmetrical and is about how elements are arranged horizontally or vertically. Rhythm creates a feeling of movement through repetition of lines, colors, shapes or textures. Emphasis draws attention to the center of interest in a design. Unity is when all parts of a design belong together and the design elements and principles are used effectively.
