NBA Basketball Court: Know the Parts of the Basketball Court

Orlando Magic v Milwaukee Bucks - Game Five

Taking a look at a basketball court for the first time can leave you confused, but once you understand what all of the end lines and restricted areas mean, it can be pretty simple to understand. For starters, the basketball court is divided into two equal sides with the same features and court dimensions. Each line on one end of the court is present on the other, and they all have the same meaning no matter what side they lie on.

Free Throw Lane

The free throw lane is a rectangle in a team's frontcourt and used to line up players during a free throw. The player shooting the free throw stands at the top of the lane at the free-throw line, while other players stand in marked spots along each side of the lane.

On offense, players may not stand in the free throw lane for more than three seconds unless they are making a move to the basket with the ball. In an NBA basketball game, defensive players may not be in the lane for more than three seconds unless they are actively guarding an offensive player. The free throw lane is sometimes referred to as the “paint” or the “key.”

Three-Point Line

The three-point line is a semicircle that surrounds the basket area on each team's side of the court. Players who stand behind the line and make a field goal are given three points instead of the standard two points for a regular field goal.

Sidelines and Baselines

The sidelines and baselines of a basketball court mark the outside boundaries for out-of-bounds purposes. The sidelines run the length of the court and the baselines are behind each basket.

Center Circle

The center jump circle is where the game action starts with the jump ball. All players other than the two jumpers must stand outside the circle until the ball is tipped. The center jump circle is not used at any other point in the game other than the opening tip and if a tip is needed to start an overtime period. Two jump circles located at the free throw line are used in the NBA for held ball situations.

Division Line

The center court line, or midcourt line, is a line running the width of the middle court that divides it into two equal sections. In high school and college, a team has 10 seconds to get the ball across the halfcourt line, while in the NBA, the time requirement is eight seconds.

Basket

The basket -- one on each end of the floor -- is made up of a backboard and a ring that holds a net, which is designed to check the ball as it passes through the basket.
