In basketball, the basketball court is the playing surface, consisting of a rectangular floor, with baskets at each end. Indoor basketball courts are almost always made of polished wood, usually maple, with 3.048 meters (10 ft)-high rims on each basket. Outdoor surfaces are generally made from standard paving materials such as concrete or asphalt. International competitions may use glass basketball courts.
