Balance is one of the key principles of art. There are three main types of balance: symmetrical, asymmetrical, and radial. Symmetrical balance involves elements of equal size and weight on both sides of a central axis, creating a sense of formality. Asymmetrical balance uses different but visually balanced elements on either side. Radial balance radiates elements out from a central point. Achieving the appropriate type of balance is important for creating a satisfying composition and visual experience for the viewer.
