In basketball, basketball court is a play surface, which consists of a rectangular floor with a basket at both ends. In professional or organized basketball, especially when played indoors, usually made of wood, often maple, and very smooth and equipped with a 10 foot rim. Outdoor surfaces are generally made of standard paving materials such as concrete or asphalt.

Dimensions
The basketball court has different sizes. At the National Basketball Association (NBA), the court is 94 times 50 feet (28.7 times 15.2 m). Under the rules of the International Basketball Federation (FIBA), the courts are slightly shorter, exactly 28 by 15 meters (91.9 x 49.2 feet). In amateur basketball, court sizes vary widely. Baskets are always 10 feet (3.0 m) above the floor (except maybe in youth competitions). The basketball court has a three-point bow in both baskets. A basket made from behind the bow is worth three points; baskets made from within this line, or with the foot of the player touching the line, is worth 2 points. The free throw line, where one stands up while taking a foul shot, is located inside a three-point arc at a distance of 15 feet from the basket. A foul shot is worth 1 point, but if the shot is made from the foul line while in the game it is still worth 2 points.

* The three-point NBA line is 3Ã, ft (0.91 m) from the sideline in the zone starting at the bottom line and ending when crossing the 23.75 ft (7.24 m) arc. The distance of 22 ft (6.70 m) is only in the dots on the three-dot line directly to the left and right of the center of the basket.
The FIBA ​​three-point line is 2.95 ft (0.90 m) from the sideline in the zone that starts at the bottom line and ends when crossing the 22.1 ft (6.75 m) arc. Distance 21.65 ft (6.60 m) is only in the dots on the three-dot line directly to the left and right of the center of the basket.

The middle circle
Two players allowed to enter this area before tipoff is a player who fights in a jump ball (usually but not always center). Both players jumped when the referee threw the ball into the air, each trying to tap the ball into the hands of players from their own team.
Three-point line
The three-point line is the line separating the two-point area from the three-point area; any shots that are converted outside this line are considered as three points. If a player shoots on the line, it counts as two points. Any offense committed in a shooting action beyond the three-point line will give players three free throws if the shot does not go in, and one if that happens.
The distance to the three-digit line from the center of the basket varies depending on the level or league, and has changed several times. This is the current distance, with a league or a level that uses any distance:
- 19.75 ft (6.02 m): SMA
- 20.75 ft (6.32 m): NCAA
- 21.65Ã, ft (6.60 m) to 22.15Ã, ft (6.75 m): WNBA and FIBA ​​â € <â € <
- 22A ft (6.71 m) to 23.75Ã, ft (7.24 m): NBA
The NBA adopted a three-point line at the start of the 1979-80 season. This is a variable range, ranging from 22 feet (6.7 m) in 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 sought to tackle the score down by shortening the overall distance of the line into a 22-foot (6.7 m) uniform around the basket. It was moved back to its original distance after the 1996-97 season. FIBA and NCAA both adopted the three-point line in 1985.
In most high school associations in the United States, the distance is 19.75 feet. This was once the distance for college basketball as well. On May 26, 2007, the NCAA rules committee agreed to move the three-point line back one foot to 20.75 feet for the men. This rule applies to the 2008-2009 season. The three-point line for women (NCAA) moves back one foot to 20.75 feet at the start of the 2011-2012 season.
International distances, used in most countries outside the United States and in FIBA ​​and WNBA competitions, are currently 6.6 m (21.65 ft) to 6.75 m (22.15 ft).
Perimeter
The perimeter is defined as the area outside the free throw line and within the three-point line. The converted shot (successfully created) from this area is called "perimeter shot" or "medium range shot." If the player's foot is on a three-point line, the shot is considered a perimeter shot.
Low posting area
The lower heading is defined as the area closest to the basket but outside the free throw line. This area is very important for the basketball strategy. Skilled low posters can score many points per game without ever taking a direct shot.
Key
Locks, free throw lanes or shaded tracks refer to the area usually painted under the basket; for the NBA it is 16 feet (4.9 m) wide, for the NCAA it is 12 feet (3.7 m) wide; for both instances it extends 15 feet (4.6 m) from the board. At the top of the rectangle is a free throw line, behind a player who fires unparalleled shots when they are violated. The circle is drawn around a free throw line with a radius of 6 feet (1.8 m); this is used for the jump ball instance, as it does in the middle circle. Two 6-inch hash lines, 3Ã, ft of free-throw line lines and 5Ã, 8 ft in from the free-throw line, show a lower defense box associated with a restricted area.
For the FIBA ​​tournament, since October 2010 the key is a rectangle with a width of 4.9 m and a length of 5.8 m. Previously it was a trapezoid 3.7 meters (12Ã, ft) wide on the free throw line and 6 meters (19 feet and 6.25 inches) at the finish line.
The key is mainly used to prevent players from staying under the opposing team basket for long periods (up to three seconds).
The forbidden area arc is a semi-circular arc drawn around the area just below the basket. With a few exceptions, surviving team members can not withdraw alleged offenses in this area. The bow is limited to all rules in North America above the high school level (men and women NCAA, NBA, and WNBA) have a radius of 4 feet (1.22 m) from the bottom of the center of the basket. Arc area limited NCAA was originally established for the 2011-12 season men and women on a 3-foot (0.91 m) radius from the bottom of the center of the basket, and extended to match (W) NBA radius for 2015 -16 seasons and beyond.
Other lines
On the NBA floor, two hash marks are drawn on the near end of the key to mark the area known as the bottom defense box. Defenders are allowed to commit charging fouls within a limited arc if the offensive player receives the ball and/or starts his drive in this area.
Also, two lines are drawn on each side line, 28 feet from each end line, pointing to the extent of the box and the coaching bench. This line marks the extent to which a trainer (other than the sidelines) can stand. Right behind this area is a team bench.
At the half-court line from the NBA floor, two lines stretch off the playing field, pointing to the place where substitute players wait before they can enter the playing field; Just behind this area are various off-court officials such as timekeepers and reserve referees.
FIBA ​​â € <â €
On April 26, 2008, FIBA ​​announced several major regulatory changes involving court signs. This change applies to major international competitions on October 1, 2010, after the World Championships that year for men and women, and becomes mandatory for other competitions on October 1, 2012 (although the national federation can adopt a new mark before 2012). The changes are as follows.
- The key shape changes from trapezoid to rectangle as in NBA, with NBA dimensions.
- The three-point line moves back to 6.75 meters (22Ã, ft 1.7 in) from 6.25 meters (20Ã, ft 6.1 in), compared to 23Ã, ft 9Ã, (7.24 m) for the NBA at the top of the arc.
