âThe basketball court is the playing surface, consisting of a rectangular floor with tiles at either end. Basketball courts come in different shapes and sizes and colors. In the NBA, the court is 94 feet by 50 ft (28.65m by 15.24m). Under International Basketball Federation (FIBA) rules, the court is minutely smaller, measuring exactly 28 m by 15 m (91'10.4 by 49'2.6). A high school court is slightly smaller, at 84' by 50' and some elementary schools have courts measuring 74' x 42'. In amateur basketball, court sizes vary widely. The baskets are always 10' (3.05m) above the floor (except possibly in youth competition). Basketball courts have a three-point arc at both baskets.
