The international basketball court for competition is a rectangular solid plane without obstacles. The standard playing field is 28m long and15m wide. The ceiling or the lowest obstacle shall be at least 7m high.
The long boundary of basketball court is called sideline, and the short boundary is called end line. All lines on the court must be very clear, with a line width of 0.05m, and draw a circle with the midpoint of the center line as the center and the radius of1.8m..
This circle is called the middle circle. The three-point shooting area is the ground area defined by two arches on the field.
Regional setting of international standard basketball court
Forbidden area: draw two straight lines from both ends of the penalty area to the ground area formed at 3 meters from each end line.
Forbidden area: it is a semi-circular area with the penalty line as the center and the radius of 1.80m outside the forbidden area, which is the area where the penalty is executed.
Three-point shooting area: it is the ground area defined by two arches on the field.
The court in NBA is 94 feet (28.65 meters) long and 50 feet (15.24 meters) wide. The spacing is measured from the inner edge of the boundary line with a line width of 2 feet (5.08 cm).
Rectangular penalty areas are marked at both ends of the stadium, which are 19 feet (5.79 meters) long and 16 feet (4.88 meters) wide.
The two ends of the court are marked with 3-point shooting lines. The drawing method is as follows: draw two lines parallel to the sideline from the baseline, each of which is 3 feet (0.9 1 m) away from the sideline and intersects with an arc with a radius of 23 feet 9 inches (7.24 meters) centered on the center of the basket. The arc radius of WNBA is 19 feet 9 inches (6.02 meters).
The radius of a circle is 6 feet (1.83 meters). The radius of the middle circle is 2 feet (0.6 1 m), and there is a middle line running through it.
There are also four marking lines with a width of 2 inches (5.08 cm) perpendicular to the sideline. Each marking line is 28 feet (8.53 m) away from the baseline and extends 3 feet (0.9 1 m) into the field.
The top surface of the hoop should be horizontal, 3.05 meters from the floor, which is equal to the distance between the two vertical sides of the backboard;
The NBA basket is 3.05 meters.
Basketball rules, chapter 2, article 4
Second, the basketball basket includes the hoop and the net.
1, the hoop shall be made according to the following requirements:
(1) solid iron bar with an inner diameter of 0.45m (45cm) and painted orange;
(2) The minimum diameter of the ring strip is 0.0 17 m (17 mm) and the maximum diameter is 0.02 0 m (20 mm), and there is a small ring or something similar on the lower edge of the ring for hanging baskets;
(3) They should be firmly installed on the backboard (see the note below), the top surface of the hoop should be horizontal, 3.05 meters away from the floor, and the distance from the two vertical sides of the backboard should be equal; Note: We suggest that it is best to install the hoop on the structural frame of the backboard, so that the stress of the hoop will not directly affect the backboard.
(4) The closest point between the backboard surface and the inner edge of the hoop is 0.15m (15cm);
(5) Compression hoops can be used. They must meet the following technical conditions:
A, they should have exactly the same rebound characteristics as the fixed ring. The constant pressure device should ensure these characteristics and protect the basket and backboard. The design and manufacture of the hoop can ensure the safety of the players;
B, those with constant locking device, when the static load applied to the top of the hoop farthest from the hoop is less than 105 kg, the constant pressure device shall not be loose;
C. When the constant pressure device is turned on, the hoop rotates downward, and the included angle with the original horizontal position shall not exceed 30 degrees;
D, open the constant pressure device, no longer apply load, hoop should be transported back to its original position.
2. The basket is made of white thread and hung on the basket; Its structure should enable the ball to pass through the basket with a short pause. The clear length is not less than 0.40 m (40 cm) and not more than 0.45 m (45 cm). Every NBA team has it, so NBDL Stadium is the home of every NBA team. The NCAA stadium is the same as that of the NBA, but the three-point line is different. The NCAA's three-point line is the same as the FIBA's three-point line standard (6.25m). First, the basketball court is a three-dimensional rectangular plane with no obstacles.
2. For the main official matches of FIBA (see Section 5 of the Official Match Procedure), the size of the basketball court is: 28m long and15m wide, and the basketball court is measured from the inner edge of the boundary.
3. For all other competitions, the appropriate departments of FIBA, such as regional committees of regional or continental competitions, or national federations of all domestic competitions, have the right to approve existing basketball courts that meet the following dimensions: the length is reduced by 4 meters and the width is reduced by 2 meters, as long as the changes are proportional to each other.
Four, the ceiling or the minimum obstacle height is at least 7 meters.
Basketball court lighting should be uniform and the luminosity should be sufficient. The placement of lighting equipment shall not interfere with the line of sight of players.
