Parts Of A Basketball Court

A basketball court is divided into many parts. Players, officials, and spectators should be familiar with them to make sense of a basketball game.

In this article, I will discuss everything you need to know about the parts of a basketball court so you play and enjoy the game right.

Basketball Court Lines And Markings

No matter what basketball court you see, you’ll notice that the area is divided. This indicates specific areas in the game where players stand, move, or shoot.

These are the different lines and markings in an organized basketball court.


These two boundary lines run the court length, establishing the playing area. It’s determined by the width of the court.

They’re also used for out-of-bounds purposes, along with the base and endlines.

Baseline or Endline

The baseline and endline extend from sideline to sideline, 4 feet behind the standard basketball backboard.

These are typically 50 feet wide and establish the playing area along the sidelines.

Its name is based on which team has the ball position. It’s called a baseline for the offensive end of the court but an endline for the defensive end.

Midcourt Line

The midcourt line (also called a halfcourt line or division line) divides the whole court in half. It separates the court into two equal-sized pieces called the front court and the back court.

As soon as the ball crosses this basketball court mark, the play of the offensive team reduces to half of the court line.

For most levels, the team only has 8 to 10 seconds to advance the ball across this division line.

Three-Point Line

Any shots made from the three-point line or arc count as three points.

Three-point lines can vary depending on the game level, and each court has a different distance.

Free Throw Line

The boundary line where a player shooting a free throw stands is called the free throw line.

It’s 15 feet away from the center of the basket, and the shooter can’t step across the line until the ball strikes the rim of the basketball hoop.

Aside from free throws, this line also defines the 3-second area, where players can’t stay for more than three seconds.

Free Throw Circle

Free throw circles are found in the free throw lane, and they’re usually 12 feet in diameter and come into play during a free throw or jump ball. 

During jump balls, non-jumpers stay outside of the circle until it’s tapped by one of the players within the area.

Lane Line

A lane line extends from the free throw line to the baseline or end lines. Its width and shape vary depending on the game’s level.

It has free-throw lane space markings to align and separate non-shooters during a free throw. It defines the free throw lane in basketball courts.

The offensive players occupy the first space during a free throw. Non-shooters of the defensive players can only step into the 3-second area once the ball is shot.

Center Jump Circle

The center jump circles located in the middle of the court line are used for the opening tip, and they’re where jump balls are called for.

Two jumpers start the game action or overtime period by tipping the ball at the center jump circle.

Center circles are 12 feet in diameter and are uniform for different courts. For an NBA court, you’ll notice two jump circles at the free-throw line instead of one center circle. 

Basketball Court Areas

Besides the different lines and markings, there are also specific areas in the court.

  • Three-second area – also known as the Paint, it’s the area below the free-throw line and between the lane lines. It’s a violation if an offensive player remains there for more than three seconds and the opposing team gets the ball. It has a series of small lines called hash marks. Non-shooting players use these hash marks to line up during a free throw. A professional league also limits the number of defensive players in the area.
  • Block – these are the two areas on the edges of the Paint called low blocks. It separates defensive and offensive players during a free throw.
  • Elbow – this is where the free throw line meets lane one. They’re important for dribble penetration.
  • Free throw line extended – a free throw line extended is an imaginary line representing the extension of the free throw to establish defensive rules.
  • Top of circle – this is located outside the free throw circle and is used as a reference for aligning players.
  • Wing – it’s at the side of the court and has a designated “ballside” or “weakside,” depending on the handler’s position.
  • Corner – this is an open area where zone defense is played. It’s also where they can trap an offensive player shooting the ball.
  • Short corner – this is a strategic offensive area along the baseline. It’s usually used against zone defenses.
  • 4′ restricted area – a small arc marks the restricted area to stop players from standing under the basket. You can easily get fouls in the restricted area.
  • Front court and back court – the frontcourt denotes the offensive end of the court. The backcourt is the area behind the mid-court line. It can’t go back court once the ball advances to the front court.
