A basketball court is rectangular and divided into two halves by a midcourt line. The court is 94 feet long and 50 feet wide, with a center circle at the midcourt line. The free throw line is 15 feet from the backboard, with two hash marks 3 feet from each side of the free throw line indicating the lower defensive box. The three-point line is 22 feet away from the basket in most parts of the court, but in the corners, it is 23 feet and 9 inches away. The key is a rectangle painted inside the free throw line, with its width being 16 feet at its widest point and the restricted arc is a curved line marking a zone underneath the basket. There are also out-of-bounds lines and sidelines, which mark the boundaries of the court.
