Semantics are crucial in sports. Coaches, technical committees, players, enthusiasts, and audiences, all use and communicate the same basic basketball court terminologies to prevent confusion and standardize the game. After all, the basketball court has an array of lines that are vital to the overall gameplay. If you aren’t aware of them yet, read on below as we’ll help you learn more about the different lines on a basketball court and their specific role in how the game is played.
1. Baselines (Endlines)
The baselines, also referred to as endlines, are the lines situated on the ends of the court. It runs from one sideline to the other and typically measures 50 feet (15 meters), lying four feet behind the basket.
The term utilized to denote them varies depending on which direction the team is playing. Endline is used for the defensive end or the backcourt, while baseline refers to the offensive end. While they are different lines that depend on the ball position, you may still hear people using them interchangeably.
The baselines also indicate the inbounds and out-of-bounds of the basketball court. In case the ball gets out-of-bound across these lines, a player needs to stand behind the baseline on the side of the backboard to bring the ball inbound.
As the name suggests, the sidelines are the two long lines on the sides of the basketball court. They run 94 feet (29 meters) for professional NBA and college basketball and serve as the markers between inbounds and out of bounds. A player is out of bounds if he crosses or steps on the sidelines. The sidelines are also where the scorers, officials, media, head coaches, and bench players stay during the game.
3. Free Throw Line
Situated 15 feet (4.6 meters), the free throw line, also called the foul line, is the mark where the players stand to shoot free throws after being fouled in a shooting motion, after a flagrant or technical foul, when the team gets in the bonus. A player shoots the uncontested shot equal to one point, but he must not step or cross the free throw line until the ball touches the rim. This line also sets the three-second area.
4. Boundary Lines
Boundary lines basically the baselines and the sidelines combined, establishing the entire perimeter of the basketball court and separating the inbounds and out of bounds. If a player possessing a ball or the ball itself touches or crosses the boundary line, it will be regarded as out of bounds and possession will be awarded to the opposing team.
5. Midcourt Line
Also called the division line or half-court line, the midcourt line is the line that runs in the middle of the basketball court, equally dividing it into two identical parts. In the NBA, the offensive team has 8 seconds to bring the ball across from the baseline to the midcourt line. School and college basketball players have longer at 10 seconds.
Once the ball crosses the line, the offensive area is restricted to this half-court and the players are not allowed to go back into the backcourt. If the ball or any player touches or crosses the midcourt line or the backcourt, it will be considered a violation.
6. Lane Lines
Lane lines are the lines that run perpendicularly from the baseline to the free throw line. The rectangular area that these lines create is usually painted and is regarded as the “paint” or the “key.” It is normally 19 feet by 12 feet wide, but the width and shape vary depending on the levels of the game.
Lane lines are also where the players line up during a free throw.. Non-shooters are not allowed to step into this rectangular area until the ball leaves the hands of the player attempting the free throw.
During an offensive play, players are also not allowed to stay in this area for over three seconds unless they’re going towards the basket while possessing the ball. Otherwise, they’ll be called for a violation.
On the other hand, defensive players must not stay inside the paint for over three seconds unless they’re guarding an offensive player. Defensive three-second violations are usually called in only in the NBA as high school basketball and the NCAA usually allows players to remain in the key for any duration.
7. Three-Point Line
The three-point line is the semi-circle that surrounds the team’s basket on each side. A field goal’s point value is determined using this line. The three-point line’s radius varies from different levels of basketball. In the NBA, it’s 23 ft. 9 inches, while it’s 22 feet and 2 inches in College, FIBA, and the WNBA.
If the successful shot is taken inside this line, the player gets two points. If the player scores behind this line, he gets three points from the field goal. If a part of the player’s shoe is inside or touches the line before the release of the ball, the shot is counted as two points.
8. Center Jump Circle
Often considered the heart of the basketball court, the action starts in the center jump circle. It’s the circular area with a 6-feet radius situated in the middle of the half-court line. It’s mainly used during the start of the game, where the two jumpers battle for the first ball possession. All players must stand outside the center jump circle until one of the jumpers tap the ball.
9. Hash Marks
Hash marks are the markings connected to the lane lines, running in towards the baskets of the free throw line. It indicates the spots where non-shooters should stand during the free throw. They must not cut inside of these hash marks during the free throw. Doing so may interfere with the player attempting the shot. Separate hash marks lie on the sidelines, which denotes the spot where the head coaches and players can stand across the scorer’s table.
