Basketball Court Lines: Explained
Understanding the lines on a basketball court is crucial in comprehending the game. Each line serves a specific purpose in the way a basketball game is played. Let’s take a closer look at the different lines on a basketball court and what they represent.
Baselines (End Lines)
The baselines, also known as end lines, are located at the ends of the court. They indicate the boundaries between inbounds and out of bounds on each side of the court. If the ball goes out of bounds across the baseline, players will stand behind the baseline and to the side of the backboard to inbound the ball. Baselines are 50 feet long.
Sidelines
The sidelines are positioned on the sides of the court and also mark the boundaries between inbounds and out of bounds. Stepping on or crossing these lines results in being out of bounds. Behind the sidelines are where the benches and scorer’s table are situated, housing the head coach, players, officials, and media. The sidelines span 94 feet in length.
Boundary Lines
The boundary lines consist of the sidelines and baselines, forming the perimeter of the basketball court. These lines divide the court between inbounds and out of bounds. If the ball or a player touches any boundary line, they are considered out of bounds, and the opposing team takes possession. The sidelines measure 94 feet, while the baselines measure 50 feet.
Free Throw Line (Foul Line)
The free throw line, also known as the foul line, is used during free throws. It is utilized when a player is fouled while in the shooting motion, after a technical or flagrant foul, or when a team is in the bonus. When awarded a free throw, a player stands behind the foul line and shoots an uncontested shot worth one point. A foul on a two-point shot that misses grants two free throws, and a foul on a missed three-point shot awards three free throws. The length of the free throw line varies depending on the level of play, with the NBA and college basketball having a greater distance compared to high school basketball.
Lane Lines (Paint or Key)
The lane lines are two lines that extend perpendicularly from the baselines and free throw lines. The rectangular area created by the free throw line and lane lines is commonly referred to as the “key” or “paint.” In the NBA, the lane lines are 19 feet long. Offensive players cannot stay within this area for more than three seconds, or a violation will be called. However, a defensive three-second violation applies only to professional-level basketball.
Midcourt Line (Half-Court Line)
The midcourt line, also called the half-court line, runs through the center of the court and divides it equally into two parts. It is instrumental in equally distributing the court and calling backcourt violations. A backcourt violation occurs when a team with possession crosses mid-court and brings the ball back into their own side of the court without the opposing team touching it. The midcourt line is 50 feet long, matching the length of the baselines.
Three-Point Line (Three-Point Arc)
The three-point line, or three-point arc, encircles each team’s basket. It determines the number of points a field goal is worth. If a shot is taken on or inside the three-point line and goes in, the team earns two points. Shots taken outside the three-point line that go in are worth three points. If any part of a player’s foot touches the line before releasing the ball, it counts as two points. The distance between the three-point line and the basket varies across different levels of basketball, with the NBA having the furthest distance.
Restricted Area
The restricted area, also known as the restricted zone or restricted arc, is a semicircle beneath the basket. In the NBA, it has a four-foot radius, while in college basketball, it is slightly smaller with a three-foot radius. Offensive charging fouls are not called within this area, and a defender inside or on the restricted area is not considered in a legal guarding position. They cannot draw a charging foul from their opponent, even if contact is made.
Hash Marks
Hash marks are small lines connected to the lane lines. They run in rows towards the basket on each side of the free throw line. During a free throw, these lines indicate where non-shooting players should stand. Only three players on each side are allowed within the hashed area. Encroaching inside the hash marks during a free throw is prohibited as it can interfere with the shooter.
By familiarizing yourself with the lines on a basketball court, you’ll gain a better understanding of the game and its rules. Each line serves a purpose in defining boundaries, assigning point values, and preventing violations.
