How many meters in diameter is the center ring of a standard basketball court

The size of the site is 28*15 meters.

The lines should be drawn in the same color, with a width of meters (5 cm) and be clearly legible. The boundary of the course is at least 2 metres away from spectators, billboards or any other obstruction. The boundary on the long side of the pitch is called the sideline, and the boundary on the short side is called the end line.

Drawing a line parallel to the end line from the midpoint of the edge line is called the middle line; The midline should be extended by 15 cm (15 cm) beyond the edges on each side.

The free throw line should be parallel to the end line, and its outer edge should be one meter away from the inner edge of the end line; The length of the edge line is meters. Its midpoint must fall on the imaginary line connecting the midpoints of the two end lines.

The ground area formed by drawing two lines from each end of the free throw line to a place of 3 meters from the midpoint of the end line (both measured from the outer edge) is called a restricted area.

The penalty area is a semi-circle drawn towards the restricted area with the center of the free throw line and the radius of the meter. The semicircles in the restricted area should be drawn as dotted lines. The position areas on either side of the penalty area are used by the players when taking the free throw.

The middle circle should be drawn on the ** of the court, with a radius of meters, measured from the outer edge of the circumference.

A 3-point shooting area is defined as the entire area of the court except for the area in the vicinity of the opponent's basket that is restricted by the conditions described below. These conditions include:

1. Meters away from the edge line, two parallel lines are drawn from the end line;

2. The arc (semicircle) with a radius of meters (to the outer edge of the arc) intersects with two parallel lines;

3. The center of the arc should be at the intersection of the vertical line of the center of the opponent's basket and the ground. The distance between the center of the circle and the midpoint within the end line is meters.

This is the standard basketball court size set by FIBA, and the NBA's is not quite the same as this one.

The diameter of the center circle of the basketball court is 4 feet, about 122 centimeters, and the dimensions of the NBA court are 94 feet (meters) long and 50 feet (meters) wide.

In the center of the court, a circle of radius and diameter shall be drawn, and the radius of this circle shall be calculated until the outer edge of the line can be colored in the middle circle, and the color must be the same color as the color painted in the restricted area, and the diameter of the basket is 45 cm, which is the standard scale.

The basketball court is 28 meters long and 15 meters wide, it is a rectangular hard plane, and there can be no obstacles on the court.

The height of the basketball court and ceiling should be more than seven meters, and the light on the court should be even and sufficient to not interfere with the view of the players.

The end line of the basketball court is the ** of both ends, the sideline is the long line on both sides of the court, the center line is the connecting line of the midpoint of the two side lines, the center line and the end line are parallel, and it is best to exceed the sideline 15 cm.

The free throw line on the court is parallel to the end line, the distance from the end line is meters, and the length of the free throw line is meters.

The penalty area is a circle with a radius of meters and all the area of the restricted area, and the other half of the circle needs to be drawn into a dotted line.

The diameter of the middle circle of the basketball court is 45 cm in diameter.

1. The diameter of the hoop.

The hoop in a basketball court is 45 cm in diameter and the accepted tolerance is 3 mm, where the horizontal diameter of the upper and lower edges of the hoop (expressed as the distance on the horizontal plane of the court) is m of the correct size. At the same time, the mesh frame of all hoops in the playground is made of metal, the thickness of the ballast is 3 mm, the height of the frame mesh is between meters, the mesh covers the hoop and the support column, and the clamping system on both sides of the mesh frame must be firm and reliable.

2. Classification of hoops.

The classification of baskets is generally divided into wooden baskets and metal baskets according to the material, and different baskets can be selected according to specific applications. The wooden hoop is made of birch wood, which has good impact resistance. The metal hoop is made of steel, which is usually simple and practical in appearance, suitable for use in large stadiums and outdoor courts, and can be used evenly by long-term low-temperature corrosion.

3. The application of hoops.

The basketball hoop is a metal instrument used to hang rebounds, it is an important facility for large imperial curved stadiums and outdoor courts, small hoops can also be used for family basketball games and games in the yard, and the small hoop is also used for indoor basketball and other game occasions. Basketball professionals also use hoops when exercising, such as shooting hoops in the playground while standing, and use hoops as targets. <>

The standard dimensions of the basketball court are 28 meters long and 15 meters wide.

The basketball court is a rectangular solid plane with no obstacles. The free throw line is from the inside of the end line to its outermost edge in meters, and the length is meters. The dimensions of all new courts are to be consistent with the requirements set by FIBA's major official competitions, and the area of a standard basketball court is as follows:

28 15 = 420 square meters.

28 meters long and 15 meters wide is the standard size of FIBA, which is the ratio of the arena of international competitions, but the American professional basketball team is different. The MLS court is 94 feet (28 65 meters) long and 50 feet (15 24 meters) wide, which explains why many NBA players are inaccurate on the international stage, because the NBA three-point distance is longer (long meters).

Basketball court terminology

1. Edge line and end line.

The long boundary of the basketball court is called the edge line, and the boundary of the short side is called the end line.

2. The middle line. At the midpoint of the edge line, there is a line parallel to the end line, which is called the middle line; The midline should be extended by 15 cm (15 cm) beyond the edges on each side.

3. Middle circle. Take the midpoint of the middle line as the center of the circle, take it as the radius, and draw a circle called the middle circle.

4. Three-point shooting area.

It is a confusing ground area that is limited by two arches on the field.

5. Restricted area.

The area of the ground marked on the playing field is defined by the end line, the free throw line, and two lines starting from the end line (the outer edge of the line is drawn 3 meters from the midpoint of the end line) and ending with the outer edge of the free throw line. These lines, with the exception of end wires, are part of the restricted area. The inside of the restricted area can be colored, but it must be the same color as the inside of the center circle.

A standard basketball court center circle is a circle centered on the midpoint of the center line and a radius of meters (the radius is measured from the outer edge of the circle).

The basketball court should be a rectangular solid plane with no obstacles. The length of the Olympic basketball competition and the World Basketball Championship are 28 meters in length and 15 meters in width, and the length of other games can be reduced by 4 meters and the width by 2 meters, requiring them to change in proportion to each other. The height of the ceiling or minimum obstacle should be at least 7 meters.

The width of the edge line should be 5 cm, and the center line should be extended by meters (15 cm) to the outside of the edge line on both sides. The end lines must be very clear and the width of the lines must be meters (5 cm).

The center circle of the NBA basketball court is 4 feet in diameter, about 122 centimeters.

The radius of the middle circle, the width of the white line, turned inward.

The radius of the third-point line, the width of the white line, turned inward.

The above are the latest standards.
