Lines and their dimensions

(1) The boundary line of the basketball court shall be marked as required, and the boundary shall be at least 2 meters away from spectators, billboards or any other obstacles. The boundary on the long side of the basketball court is called the sideline, and the boundary on the short side is called the endline.

(2) Midline Draw a line parallel to the end line from the midpoint of the sideline, which is called the midline; the midline shall extend 0.15 meters (15 cm) from the sidelines on both sides. 

三、Free throw line, restricted area and penalty area

1. The free throw line must be parallel to the end line, and its outer edge is 5.80 meters away from the inner edge of the end line; the side line is 3.60 meters long. Its midpoint must fall on the imaginary line connecting the midpoints of the two end lines.

2. The ground area formed by drawing two lines from both ends of the free throw line to a distance of 3 meters from the midpoint of the end line (both measured from the outer edge) is called the restricted area. If it is colored inside the restricted area, its color must be the same as the color inside the center circle.

3. The penalty area is the restricted area plus a semicircular area drawn to the restricted area with the center of the free throw line as the center and a radius of 1.80 meters. The semicircle in the restricted area shall be drawn as a dotted line.

4. The location areas on both sides of the penalty area are for players to use during free throws.

The 3-point shooting area of ​​a team refers to the entire court area except for the area around the opponent's basket that is restricted by the following conditions. These conditions include:

1. Separately 1.25 meters from the sideline, draw two parallel lines from the end line;

2. The arc (semi-circle) with a radius of 6.25 meters (measured to the outer edge of the arc) intersects two parallel lines;

3. The center of the arc should be at the intersection of the center vertical line of the opponent's basket and the ground. The distance between the center of the circle and the midpoint of the inner edge of the end line is 1.575 meters.
