To fully understand basketball, it’s essential to have a good grasp of the basketball court diagram and what each line represents.
Below we’ll look at the various lines on a basketball court and their significance.
Whether you are a player, coach, or simply a fan of the game, this knowledge will enhance your understanding and appreciation of basketball.
The Baseline
The baseline is the boundary line that runs along the length of the court at each end.
It marks the out-of-bounds area behind the backboard and is used to determine whether a player is in bounds or out of bounds.
The baseline is also where players inbound the ball after a made basket or when the ball goes out of bounds.
The Sidelines
The sidelines are the boundary lines that run along the length of the court on each side.
They mark the out-of-bounds area on the sides of the court and are used to determine whether a player is in bounds or out of bounds.
The sidelines are also where players inbound the ball after a timeout or when the ball goes out of bounds on the sides.

The Center Circle
The center circle is located at the midcourt and is used for the jump ball at the beginning of the game.
It is also used to restart play after certain stoppages, such as a held ball or a technical foul.
The circle has a radius of 6 feet and is where the opposing players involved in the jump ball must stand.
The Three-Point Line
The three-point line is one of the most important lines on a basketball court.
It marks the area from which a shot is worth three points if made.
The line is an arc that extends 23 feet 9 inches from the center of the basket on the sides and 22 feet from the center at the top.
Shots made outside the three-point line are considered long-range shots and can significantly impact the outcome of a game.
The Free-Throw Line
The free-throw line is located 15 feet from the backboard and is used for free-throw attempts.
When a player is fouled in the act of shooting or when a team commits a technical foul, the player is awarded free throws.
The player stands behind the free-throw line and attempts to make the shot without any defenders.
Each successful free throw is worth one point.
The Key
The key, also known as the paint or the lane, is the rectangular area located in front of each basket.
It is bounded by the baseline, the free-throw line, and two parallel lines that extend from the free-throw line to the baseline.
The key is where players position themselves during free-throw attempts and where offensive players can be called for a three-second violation if they stay in the key for more than three seconds without actively guarding an opponent.
The Half-Court Line
The half-court line divides the court into two halves and is located at midcourt.
It is used to determine whether a team has successfully advanced the ball past half-court within the allotted time.
In professional basketball, teams have eight seconds to advance the ball past half-court, while in college and high school basketball, the time limit is ten seconds.
The Restricted Area
The restricted area, also known as the “charge circle” or “no-charge zone,” is a semi-circle located in front of the basket.
It is used to determine whether a defensive player is in a legal guarding position when attempting to draw a charging foul.
If an offensive player makes contact with a defensive player outside the restricted area, the defensive player can be called for a blocking foul instead of a charging foul.
The Out-of-Bounds Area
The out-of-bounds area refers to the space outside the boundary lines of the court.
If a player touches the floor or any object outside the boundary lines while in possession of the ball, it is considered out of bounds, resulting in a turnover.
The out-of-bounds area also includes the space above and below the court, so if a player jumps and catches the ball while in the air but lands out of bounds, it is also considered out of bounds.
The Backboard
The backboard is a rectangular board that is attached to the basket.
It is used to provide a target for players shooting the ball and helps determine whether a shot is successful or not.
The backboard is made of transparent material, usually glass or acrylic, and has markings to indicate the proper alignment of the rim and the backboard.
The Rim
The rim is the circular metal hoop that is attached to the backboard.
It is 18 inches in diameter and is where players aim to shoot the ball through to score points.
The rim has a net attached to it, which helps to slow down the ball after it passes through the hoop.
