NBA stadium specifications? Stadium specifications
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 inches (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. (Position area and neutral area and some short marking lines are omitted. )
What are the specifications of the stadium? (1) area:
The stadium must be rectangular, and its length cannot exceed 130 yards and cannot be shorter than 100 yards. Its breadth is super.
More than one hundred yards, not less than fifty yards. (For international competitions, it is 1 10 to 120 yards long and 70 to 80 yards wide. In any case, the length must be greater than the width.
(2) Boundary:
The playing field must have a clear boundary, the line width should not exceed five inches (12 cm), and there should be no V-shaped grooves. Lines with longer sides are called sideline lines; The line with the shorter end is called the end line (or goal line). At the four corners of the stadium, a small flagpole with a flat top should be erected, and the height of the flagpole should not be less than five feet (one meter and fifty centimeters); A flagpole of the same style should also be erected at least one yard away from the sideline outside the center line of the stadium. The center line should pass through the stadium, and the center of the stadium should draw a clear point, and draw a circle with this point as the center and 10 yard as the radius.
(3) Target area:
On the end lines (goals) at both ends of the court, six yards away from the goalposts, draw a vertical line with a length of six yards into the court to make it at right angles to the end lines, and draw a line to connect the two vertical lines to both ends of the court and parallel to the end lines. The ground inside the three lines and the end line is called the goal area.
(4) Forbidden area:
Draw a vertical line 18 yards away from the goalpost 18 yards on the end line at both ends of the court, so that it is at right angles to the end line, and draw a line to extend these two vertical lines to the connecting line at both ends of the court and parallel to the end line. The field between these three lines and the end line is called the penalty area. Make a clear mark at the center of the goal line from the stadium 12 yards, which is the penalty point of 12 yards. Draw an arc outside the penalty area with each penalty point as the center and ten yards as the radius.

What are the specifications of the NBA basketball court? Stadium floor
The basketball playing field should be a rectangular solid plane without obstacles.
The length and width of the Olympic basketball competition venue and the World Basketball Championship venue are 28m and15m respectively. The length and width of other competitions can be reduced by 4 meters and 2 meters, and the change is in direct proportion. The spacing shall be measured from the inner edge of the boundary.
All new stadiums must meet the requirements of FIBA: 28m long and15m wide.
The ceiling or the lowest obstacle should be at least 7 meters high.
The boundary of the long side is called the sideline, and the boundary of the short side is called the end line. All lines on the court must be very clear with a line width of 0.05m (5cm).
Draw a horizontal line parallel to the end line from the midpoint of the sideline, which is called the center line. The center line shall extend 0. 15m (15cm) to the outside of both side lines.
Draw a circle with the midpoint of the center line as the center and 1.80m as the radius (the radius is measured from the outer edge of the circle), which is called the middle circle.
The three-point shooting area is the ground area defined by two arches on the field. Throw three points outside this area.
The ground area formed by drawing two lines from both ends of the penalty line to the place 3 meters away from the midpoint of the end line (all measured from the outer edge) is called the restricted area. Its function is: when the ball is under the control of the team, limit the players to stay in the opponent's penalty area for no more than 3 seconds.
The penalty area is a semi-circular area with the penalty line as the center and the radius of 1.80m outside the penalty area, which is the area where penalty is executed.
The basketball court has soil, cement, asphalt and wood. When conditions permit, wooden floors are usually used. Soil, cement and asphalt sites are relatively economical and widely used at the grass-roots level, but attention should be paid to leveling the ground to prevent injury accidents.
Any site requires smooth ground, no bumps, no pebbles, daily maintenance and clear line drawing.
Lighting the competition venue shall be at least 1500 lux, measured from the stadium 1 meter. Lighting should meet the requirements of TV broadcast.
The difference between China basketball court and American NBA court.
The court in NBA is 94 feet (28.65 meters) long and 50 feet (15.24 meters) wide.
The stadium specifications in China are the same as those stipulated by FIBA, with a length of 28m and a width of 15m.
This basket is 3.05 meters high.
According to 90 points in the NBA game, the hit rate is 50%, that is, it takes about 90 times for two attacks to succeed once. In the attack, the center rarely moves, and it takes about 70 meters to return to the backcourt. In other words, the center runs 6300 meters per game, and the defender and striker run in the attack. The specific running distance cannot be calculated.
Volleyball court specifications Volleyball court requirements:

3. Goal area: Draw a 5.50-meter-long line perpendicular to the goal line at both ends of the playing field 5.50 meters away from the inside of the goal post, with one end connected to the goal line and the other end drawing a line parallel to the goal line. The area within these three lines and the goal line is called the goal area.
4. Penalty area: On the goal lines at both ends of the playing field, at a distance of16.50m from the inside of the goalpost, the area within these three lines and the goal line is called penalty area, and the midpoint of the two goal lines is clearly marked, which is perpendicular to the field 1 1 m, which is called penalty area. Draw an arc outside the penalty area with the penalty spot as the center and 9. 15m as the radius, which is called penalty arc.
5. Corner area: Take the intersection of sideline and goal line as the center and 1 m as the radius, draw a quarter arc into the field, and the area within this arc is called corner area.
6. Goal: The goal should be located in the center of each goal line, consisting of two connecting lines which are 7.32 meters apart and equal to the flag point in the west corner, as well as a vertical gatepost and a horizontal bar whose lower edge is 2.44 meters off the ground. In order to ensure safety, both the fixed goal and the movable goal must be stably fixed on the field. The width and thickness of the doorpost and crossbar shall be symmetrical and equal, and shall not exceed 12 cm. The net is tied to the goalposts, beams and the ground behind the goal. The net should be properly propped up so that the goalkeeper has enough room to move.
Note: The net can be made of hemp, jute or nylon. Nylon rope is ok, but it must not be thinner than hemp or hemp rope.
Football, with the reputation of "the first sport in the world", is the most influential single sport in the world. In a standard football match, the two teams each send 10 players and 1 goalkeeper, * * *1/people to fight and attack on a rectangular grass court. The purpose of the game is to shoot the football into the opponent's goal as much as possible, and you can get one point for each goal. When the game is over, the team with the most points wins. If the score is the same within the specified time, it depends on the rules of the game. You can draw lots, play overtime or shoot each other (12 steps) to score. In the football match, except the goalkeeper can touch the ball with his hand in his own restricted area, each player can only control the football with other parts of his body except his hand (except the foul ball).
