The Basketball Hoop: Its Story

In basketball the points are scored when a player throws a ball into a hoop suspended 10ft above the ground. In the NBA and NWBA the official size of the basketball hoop is 18in (46cm) in diameter. The net that extends from the hoop ranges from 15-18in (38-46cm) in length and is usually made from nylon. The hoop is made from metal, usually steel and in competitive games is connected to a backboard.
