Balance is the state in which the elements of a design achieve a harmonious, satisfying equilibrium, with nothing out of proportion or overemphasized to the detriment of other elements in the room. Balance assumes great importance because every room has a mixture of different shapes, colors, patterns, textures, lines and light.
Symmetrical balance occurs when an arrangement of identical elements occurs on a common axis, for example, a living room with identical furniture on either side of a fireplace. Asymmetrical balance is a more informal method of arrangement.
Elements that are more heavily textured or detailed have more visual weight than plain elements. Among objects with similar shapes, forms, colors, and textures, larger objects weigh more than smaller ones, visually. Multiple smaller objects closely grouped together can “balance” a single object of similar volume and area. For instance, if you have a room with a large object, such as a piano, in one corner of the room, you can create balance across from it with several small objects, such as three plants or a significant sculpture. Dark and bright colors lend heavier weight to elements than lighter and paler colors.
