The Game Court
Posted Sep 17 2002 12:31PM
An NBA game court is 94 feet long and 50 feet wide, divided in half by a midcourt line. Each half is a mirror image of the other. This diagram shows some of the key markings and areas of an NBA basketball court.
Backboard: The basket ring is attached to the backboard, which measures six feet horizontally and 3.5 feet vertically. On the backboard, a two-inch white rectangle is centred behind the basket ring, with outside dimensions of 24 inches horizontally and 18 inches vertically.
Backcourt: A team's defensive half of the court.
Basket: The ring and net through which the ball must pass in order to score a field goal. The basket ring is 10 feet above the floor and measures 18 inches in diameter.
Basketball: The game ball, which is nine inches in diameter, with between 7.5 and 8.5 pounds pressure.
Baseline: The line at each end of the court, also known as the endline. The middle of the basket is five feet three inches from the baseline.
Free Throw Line: A marking at the top of the lane, behind which players must stand when shooting free throws. The free throw line is 15 feet from the backboard.
Frontcourt: A team's offensive half of the court.
Lane: A painted area of the court between the baseline and free throw line. Also called the key because in the early years it was key-shaped. It was twice widened to its present rectangular shape and now is 16 feet wide.
Midcourt Line: Also called the division line, the midcourt line divides the court in half.
Three-Point Line: An arc that is 23 feet nine inches at the top and 22 feet on the baselines, measured from the middle of the basket. A field goal taken from beyond this line is worth three points.
