  1. You can hang your backyard hoop any way you like, but if you want to play like the pros, the National Basketball Association (NBA) rules have specific dimensions for every aspect of basketball:

    • Ball: The ball must be leather, 30 inches (76 centimeters) around and 9 inches (23 centimeters) in diameter. Before play, you should inflate the ball to 7.5 to 8.5 pounds per square inch (0.51 - 0.57 atmospheres).
    • Hoop: The hoop should be a metal rim, 18 inches (46 centimeters) in diameter with a dangling nylon net that is 15 or 18 inches (38 or 46 centimeters) long. The hoop must be 10 feet (3 meters) off the ground.
    • Backboard: There is always a rectangular slab of durable material behind the hoop, which is designed to withstand the ball's impact. This backboard has a width of 6 feet (1.8 meters) and is 3.5 feet (1 meter) high.
    • Court: The playing surface is a rectangle measuring 94 x 50 feet (29 x 15 meters).
