Basketball court
In basketball, the basketball court is the playing surface, consisting of a rectangular floor, with baskets at each end. Indoor basketball courts are almost always made of polished wood, usually maple, with 10 feet (3.048 m)-high rims on each basket. Outdoor surfaces are generally made from standard paving materials such as concrete or asphalt. International competitions may use glass basketball courts.
Basketball courts come in many different sizes. In the National Basketball Association (NBA), the court is 94 by 50 feet (28.7 by 15.2 m). Under International Basketball Federation (FIBA) rules, the court is slightly smaller, measuring 28 by 15 meters (91.9 by 49.2 ft). In amateur basketball, court sizes vary widely. Many older high school gyms were 84 feet (26 m) or even 74 feet (23 m) in length. The baskets are always 10 feet (3.05 m) above the floor (except possibly in youth competition).
Basketball courts have a three-point arc at both baskets. A basket made from behind this arc is worth three points; a basket made from within this line, or with a player's foot touching the line, is worth 2 points. The free-throw line, where one stands while taking a foul shot, is located within the three-point arc at 15 feet from the plane of the backboard. A foul shot is worth 1 point, but if a shot is made from the foul line while in play it is still worth 2 points.
The only two players permitted to enter this area prior to the tipoff are the players contesting the jump ball (usually but not always centers). Both players jump when the referee throws the ball in the air, each attempting to tap the ball into the hands of a player of their own team.
The three-point line is the line that separates the two-point area from the three-point area; any shot made beyond this line counts as three points. If the shooting player steps on the line, it is counted as two points. Any foul made in shooting beyond the three-point line would give the player three free throws if the shot does not go in, and one if it does.
The distance to the three-point line from the center of the basket varies depending on the level or league, and has changed several times. These are the current distances, with the league or level using each distance:
The NBA adopted the three-point line at the start of the 1979–80 season. This is of variable distance, ranging from 22 feet (6.7 m) in the corners to 23.75 feet (7.24 m) behind the top of the key. During the 1994–95, 1995–96, and 1996–97 seasons, the NBA attempted to address decreased scoring by shortening the overall distance of the line to a uniform 22 feet (6.7 m) around the basket. It was moved back to its original distance after the 1996–97 season. FIBA and the NCAA both adopted the three-point line in 1986.
Most high school associations in the USA have a distance of 19.75 feet. This was formerly the distance for college basketball. On May 26, 2007, the NCAA playing rules committee agreed to move the three-point line back one foot to 20.75 feet for the men. This rule went into effect for the 2008–2009 season. The three-point line for women (NCAA) moved back one foot to 20.75 feet at the start of the 2011–12 season. During the 2019 offseason, the NCAA men's playing rules committee adopted the FIBA arc in a two-phase implementation. Division I adopted the new arc in 2019–20, and other NCAA divisions did so in 2020–21. The NCAA women's arc was moved to the FIBA arc in 2021–22.
