The above demonstrates the principle of balance which says that two very different things are equally essential at the same time. Balance provides stability and structure to a design. Balance in design determines the distribution of design elements- what, where and how elements are placed in a composition. You balance visual interest in design by controlling the distribution of elements that make up the design. The key is to ensure elements are placed in a way that feels right to the eye.
There are two systems used to achieve balance: Symmetrical or Asymmetrical Balance. Symmetrical balance is achieved when the weights of elements on two equal halves of a design are same. Asymmetrical balance is achieved by the use of contrast. For instance, a dark element could need to be balanced by several lighter elements. There are no rules or limits with asymmetrical balance. The attraction of asymmetrical balance is its lack of rules. This allows for greater freedom in creativity and helps emphasize necessary areas of interest. However, the downside is that it can lack organization and order. This can be corrected by careful placement of elements and the use of other organizational techniques.For instance, try playing with elements of different sizes. Balance can be achieved by placing a large element on one side of your design and several smaller elements on the other side.
Whether or not you choose symmetrical or asymmetrical balance, proper use of design principle of balance ensures that necessary attention is drawn to the whole design and not just a specific area or element alone.
