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.

The inside circle is two feet. The free throw circle also has a radius of six feet. The free throw line is 19 feet from the baseline and 15 feet from the basket.
