Symmetrical Balance creates a mirror image from one side of an axis to another. It is formal and rigid. It can add stateliness or dignity to a room. Asymmetrical Balance creates a feeling of equilibrium by using different objects of the same visual weight on both sides of the axis. It is created through variation in shape, color and pattern.
Asymmetrical balance tends to be more interpretive and less formal.
Radial Balance is created by working outward in a circle from a central point. Radial balance tends to be pleasing to the eye and usually adds interest to an interior design. For example, a grand piano placed in an alcove would be out of scale with its surroundings. The same piano would be in scale in a large room with high majestic ceilings. Furnishings, while being in scale with the room, must also be in proportion to one another.
