It is the rectangular-shaped area on the court underneath the basket, inside the lane lines, extending from the baseline to the free-throw line. The size of the paint varies depending on the league and level of competition. In the NBA and WNBA, the paint is 16 feet wide, while for the NCAA, high school, and junior high school, it is 12 feet wide. The FIBA paint was changed to a rectangular shape in 2010, with a width of 16.08 feet.

The paint is also known as 'the key' or 'the lane'
The painted area on a basketball court, usually coloured differently from the rest, is known as "the paint". It is also referred to as "the key" or "the lane". The key derives its name from its original shape: a six-foot-wide lane that culminated in the free throw circle and resembled a key used for locks or doors. The paint/key/lane is the most active area on the basketball court, as most of the action occurs here. It is where players can score points by shooting or dunking the ball within its boundaries. It is also where players can post up to take a shot or make a move to get closer to the basket.
The three-point line extends from either side of the top of the key. The top of the key is a strategic location for calling offensive plays. Once the point guard brings up the ball to the top of the key, the offence can balance the court by distributing offensive players to both sides of the court. While the point guard often calls plays at the top of the key, it is not a good place to attempt a field goal or three-point shot. The top of the key is the furthest point from the basket for a two-pointer, and statistics show that three-point shot attempts from the corner are more successful than two-pointers from the top of the key.
The key has a defensive three-second rule, which states that a defensive player cannot spend more than three seconds in the key without guarding an opponent. If they do, it is a team technical foul, and the offence receives a free throw and possession of the ball. There is also an offensive three-second violation, where an offensive player cannot remain in the key without making a shot, or passing or dribbling out of the lane, while their team is in control of the ball.
The size and shape of the key are defined by the level of play. In the NBA, the key is a 16-foot-wide rectangle. The NCAA and NAIA use a 12-foot-wide rectangle, while FIBA adopted a 16-foot-wide rectangle in 2010, moving away from its previous trapezoidal shape.

Its dimensions vary depending on the level of play
The paint, also known as the key, the lane, or the free throw lane, is a vital part of the basketball court. It is the rectangular-shaped area on the court underneath the basket, inside the lane lines, that extends from the baseline to the free-throw line. The paint is important because it is one of the best spots to shoot from on the court, and players dedicate time to mastering moves to be played in this area.
The dimensions of the paint vary depending on the level of play. In the NBA, the WNBA, and the Euroleague, the paint is 16 feet wide. The WNBA and NCAA use an identical court size—94 feet long by 50 feet wide—but the NCAA and NAIA have retained a 12-foot key. In FIBA, the paint is 16.08 feet wide, and the court is 91.86 feet long and 49.21 feet wide. High school and junior high school courts use a 12-foot key, with a court size of 84 feet long and 50 feet wide, although older gyms may be smaller.
The size of the key has changed over time. In the early days of basketball, the lane was narrower, creating a keyhole shape. The key was widened to 12 feet at the start of the 1951-52 NBA season to reduce the effectiveness of imposing centers. It was widened again to 16 feet in the 1964-65 season to limit the dominance of players like Wilt Chamberlain. The FIBA key was changed from a trapezoid to a rectangle in 2010, with the same dimensions as the NBA key.

The NBA and WNBA have a wider paint than college, high school and junior high school games
The rectangular-shaped area on a basketball court underneath the basket, extending from the baseline to the free-throw line, is called "the paint". It is also known as "the key" or "the lane". The paint is considered vital in basketball due to its proximity to the basket, making it one of the best spots to shoot from. Game plans are often centred around it, and players dedicate time to mastering moves to be played in this area.
The size of the paint varies among levels of play. In the NBA and WNBA, the paint is 16 feet wide. In college, high school and junior high school basketball, the paint is 12 feet wide. The NBA has altered the dimensions of the paint twice in the past. The first change was made to limit the dominance of George Mikan, one of the first "giants" of the NBA, standing at 6'10". The second change was implemented in 1964 to counter Wilt Chamberlain, who was 7'1" tall. Overall, these modifications aimed to balance the advantages of taller players with those of shorter players.
The NBA and WNBA courts are 94 feet long and 50 feet wide, identical to the court size used in college basketball. High school courts are shorter, measuring 84 feet long and 50 feet wide. Junior high school courts are typically the smallest, at 74 feet long and 42 feet wide.
While the size of the paint and the overall court layout differ across various levels of basketball, certain dimensions remain consistent. For instance, the rim is always 10 feet off the ground, and the backboard dimensions and rim size are standard across the NBA, WNBA, college, high school and junior high school levels.

The paint is an important part of the court due to its proximity to the basket
The paint, also known as the key or the lane, is a rectangular area on the court that sits directly underneath the basket. Its proximity to the basket makes it a high-value area for players to shoot from, increasing the likelihood of scoring points. This area is also where players establish a position or post up to receive a pass, creating an opportunity to score or pass to a teammate.
The paint extends from the baseline to the free-throw line, with the free-throw line itself being 15 feet from the perpendicular projection of the backboard onto the court. The size of the paint varies depending on the league and level of competition. In the NBA, the WNBA, and FIBA competitions, the paint is 16 feet wide, while at the NCAA level and for high school and junior high school games, it is 12 feet wide.
The term "key" is derived from the shape of a locksmith's key, as the area resembles a keyhole due to the narrower lane before it was extended by the NBA. The paint is also sometimes called "the lane" because the free-throw line and the lines extending from it to the baseline create a long, lane-like area. The area on the lane lines and near the basket is known as the low post, which is a fundamental strategic area in basketball. Skilled players in this position can score many points per game without relying on jump shots.
The paint is subject to specific rules that govern gameplay within it. For example, players on offense are only allowed to remain in the paint for three seconds. This rule was implemented to prevent players from staying beneath the basket of their opponents' team for extended periods. The paint is also where the game usually starts, with plays often being directed by point guards in the top of the key area around the jump ball circle.

The area is also referred to as 'the low post' or 'the high post'
The paint, also known as the key or the lane, is the rectangular area on the court underneath the basket, extending from the baseline to the free-throw line. The area on the lane lines and near the basket is called the low post. Players establish a position or "post up" in this area to receive a pass and attempt to score points or pass to a teammate.
The low post is near the exterior of the paint and slightly above the basket. Low post players typically position themselves outside the lane lines, with their backs to the basket, especially when guarded by a low post defender. The low post is also referred to as the "block", which signifies the general location of the low post area.
The high post is higher up than the low post, more towards the free-throw line, and is used in the same way. It is the area that surrounds the free-throw line and extends to the top of the three-point line. The edges of the free-throw line are typically known as the high post elbows or simply the elbow areas of the court.
The high post is a vital area in basketball strategy, as it provides scoring opportunities for all five players on the court. A high post offense is a strategy that emphasizes the use of a high post player to gain possession of the basketball and create scoring opportunities near the basket or around the perimeter. The high post has the option to shoot, drive, or pass when they have an advantage.
