A basketball hoop is a circular metal rim that is mounted on a backboard, designed for the game of basketball. The hoop is positioned 10 feet above the ground and has a diameter of 18 inches. It is typically made of steel and is often painted orange. The backboard, usually made of glass or acrylic, helps players aim their shots and can be rectangular or fan-shaped. Players score points by shooting a basketball through the hoop. The hoop is an essential part of the game, as it defines the scoring area. In professional leagues, such as the NBA, the specifications for the hoop and backboard are standardized to ensure consistency in play.
