The following is list of equipment and related information for the sport of Basketball:

  1. The only essential equipment in basketball is the ball and the court: a flat, rectangular surface with baskets at opposite ends.
  2. Competitive levels require the use of more equipment such as clocks, scoresheets, scoreboards, alternating possession arrows, and whistle-operated stop-clock systems.
  3. The men's ball's circumference is about 30 inches (76 cm) and weighs about 1 lb 5 oz (600 g).
  4. The women's ball's circumference is about 29 inches (73 cm) and weighs about 1 lb 3 oz (540 g).
  5. A regulation basketball court in international games is 28 by 15 meters (approx. 92 by 49 ft) and in the NBA is 94 by 50 feet (29 by 15 m).
  6. Most courts are made of wood.
  7. A cast-iron basket with net and backboard hang over each end of the court.
  8. At almost all levels of competition, the top of the rim is exactly 10 feet (3.05 m) above the court and 4 feet (1.2 m) inside the endline.
  9. While variation is possible in the dimensions of the court and backboard, it is considered important for the basket to be the correct height; a rim that is off by but a few inches can have an adverse effect on shooting.
