Basketball courts come in a variety of sizes, depending on the level of play and the organisation. The National Basketball Association (NBA) has the largest court dimensions, measuring 94 feet by 50 feet (28.7 by 15.2 metres). The International Basketball Federation (FIBA) rules specify a slightly smaller court, at 28 metres by 15 metres (91.9 by 49.2 feet). In the UK, the playing area is slightly more flexible, with a minimum length of 26 metres and a minimum width of 14 metres. Amateur basketball courts can vary widely, with high school gyms often shorter at 84 feet or even 74 feet in length. The baskets are always 10 feet (3.05 metres) above the floor, and the three-point line, free-throw line, and key have specific measurements that vary slightly between organisations.

Basketball court dimensions

The dimensions of a basketball court vary depending on the level and type of basketball being played. Basketball courts are rectangular and have baskets at each end.

NBA and WNBA Courts

In the National Basketball Association (NBA), the court is 94 feet by 50 feet (28.7 by 15.2 metres). The basket is 10 feet (3.05 metres) above the floor. The key is 16 feet wide and 19 feet from the baseline to the foul line. The three-point line varies in distance, ranging from 22 feet (6.7 metres) in the corners to 23.75 feet (7.24 metres) behind the top of the key.

FIBA Courts

Under International Basketball Federation (FIBA) rules, the court is slightly smaller, measuring 28 metres by 15 metres (91.9 by 49.2 feet). The basket is also 10 feet (3.05 metres) above the floor. The FIBA-spec key is a rectangle that is 4.9 metres wide and 5.8 metres long. The three-point line is 6.75 metres (22.15 feet) from the basket.

NCAA Courts

National Collegiate Athletic Association (NCAA) basketball courts have similar dimensions to the NBA and WNBA courts. However, the key is only 12 feet wide, and the three-point line is 20 feet and 9 inches from the centre of the basket.

The distance of the three-point line varies depending on the league and level of play. In the NBA, the three-point line ranges from 22 feet (6.7 metres) in the corners to 23.75 feet (7.24 metres) behind the top of the key. The NCAA three-point line is shorter, at 20 feet 9 inches (6.32 metres) from the centre of the basket, while high school basketball courts typically have a three-point line of 19 feet 9 inches (6.02 metres). FIBA and NCAA both adopted the three-point line in 1986, with the FIBA three-point line distance being experimented with in the 2018 and 2019 seasons.

The key

The three-point line, which is located at a variable distance from the key, is another important feature of the basketball court. The NBA three-point line ranges from 22 feet in the corners to 23.75 feet behind the top of the key. The NCAA three-point line is slightly shorter at 20 feet, 9 inches, while high school basketball courts have a three-point line of 19 feet, 9 inches.

The free-throw line

The free throw circles have a diameter of 12 feet. They come into play on free throws and jump balls. Shooters must stay inside this circle when taking a free throw. The circle is also used for jump balls. Lane lines run from the free-throw line to the baseline to form the 'key'. The key, free throw lane or shaded lane refers to the usually painted area beneath the basket.

When a free throw is awarded, an official shall put the ball in play by delivering it to the free-throw shooter. The shooter shall be above the free-throw line and within the upper half of the free throw. They shall attempt the free throw within 10 seconds of controlling the ball in such a way that the ball enters the basket or touches the ring.

Teammates of the free-throw shooter must occupy the next adjacent spaces on each side. Only one of the third spaces may be occupied by an opponent of the free-throw shooter. It is not mandatory that either of the third spaces be occupied by an opponent but may not be occupied by a teammate. If there is a discrepancy, teammates of the free-throw shooter will occupy the spaces first.

The basket

A basketball court features a rectangular playing area, and at each end, elevated above, are the baskets. The basket, or hoop, is the target for players to score points by putting the ball inside it. It is a critical part of the game and is positioned at a height of 10 feet (3.05 meters) from the ground. The basket consists of a metal hoop that is 18 inches (46 cm) in diameter and is attached to a backboard, which measures 6 feet (1.83 meters) wide and 42 inches (1.07 meters) tall. The hoop is positioned so that its lower edge is exactly 10 feet from the floor, and it is fixed firmly to the backboard. The backboard, usually made of glass, plexiglass, or a similar transparent material, is positioned vertically and perpendicular to the court surface. It is often marked with a thin red or white border to help players gauge the distance and position of the basket.

The net, attached to the hoop, is designed to slow the ball's return after a successful shot. It is typically made of nylon or cotton and features a mesh-like design. The net ensures that the ball falls away from the shooter and their teammates, preventing confusion and allowing for a clear retrieval. The combination of the hoop, net, and backboard make up what is commonly referred to as the 'basket'. The dimensions and design of the basket have remained largely consistent since the inception of the sport, with only minor adjustments made over time to enhance the game's safety and playability.

Today, the basket remains an iconic symbol of the sport, instantly recognizable worldwide. Its dimensions and design are standardized across all levels of play, from recreational to professional leagues, ensuring a consistent playing experience for athletes of all ages and skill levels. The basket's height and positioning require players to develop a range of skills, including shooting, layups, and dunking, all of which contribute to the dynamic and exciting nature of the game.
