A wood bracket is a structural support, and the most recognized bracket shape is triangular. The bracket bears a projected weight, such as a shelving unit. Brackets are similar to corbels in function; however, brackets are generally thinner than corbels, and often decorated with cut away carvings, which creates a "gingerbread" pattern that includes negative spaces.

Brackets can be found in both very large and very small sizes. In European architecture, brackets commonly support eaves, windows, and even whole balconies. During Victorian times, eave brackets were most often decorative and installed for their aesthetic value, rather than for functional purposes.

Wood brackets for the home most often support and accent shelving units, and indeed, a shelving unit can be defined by its bracket set. A bracket bearing elaborate wood carvings can add exceptional value, revamping an old or plain shelving unit.

Bracket wood carvings vary greatly, though curling filigree and scroll designs are most popular. The bracket is defined by its ornamentation which is achieved by cut-away or surface relief forms. A bracket always supports with a right angle, commonly triangular in shape, however, the inside of the bracket can have a square or arched inside shape, and other forms are often found, though they are less common.
