The game of basketball is played between two teams, five players to a side, on a court 94 ft long and 50 ft wide, with two ten ft basketball hoops on either side. Under the International Basketball Federation rules the court is a little smaller. Indoor courts are usually made of wood. There are lines on the court marking half court, the three point arc around each basket (varies between 20 ft to 22 ft depending on level of play), and the key (12 ft to16 ft wide and 15 ft from the backboard).
