The long side of the venue is called the sideline, and the short side is the end line. The venue is evenly divided into two halves by a centerline, which should extend 0.15 meters outward from both sides of the sideline. The distance between the free throw line and the inner edge of the end line is 5.80 meters, and the length of the free throw line is 3.60 meters. Draw a semicircle with the midpoint of the free throw line as the center and a radius of 1.80 meters, and this area is the free throw zone. The three-point shooting area is the ground area defined by two arched arcs on the field, and shooting outside of this area can earn three points.

Facilities

A basketball hoop is the core facility of a basketball court. It consists of a rebound, basket, and stand. The backboard should be a flat rectangle with dimensions of 1.80 meters wide, 1.05 meters high, and a bottom edge 2.90 meters above the ground. The basket is a metal ring with an inner diameter of 0.45 meters, fixed on the backboard, and the top of the basket should be horizontal, 3.05 meters above the floor.

Draw two lines perpendicular to the goal line from 5.50 meters inside each goalpost, extending 5.50 meters into the playing field and connecting with a line parallel to the goal line. The area composed of these lines and the goal line is the goal area. Draw two lines perpendicular to the goal line from 16.50 meters inside each goalpost, extending 16.50 meters into the playing field and connected to a line parallel to the goal line. The area formed by these lines and the goal line is the penalty area. Drawing an arc outside the penalty area with a radius of 9.15 meters from each penalty point is called a penalty arc.

The goal is located in the center of two goal lines, consisting of two vertical pillars 7.32 meters apart and a horizontal crossbeam with a lower edge 2.44 meters above the ground. The depth of the goal, extending from the inner edge of the goalpost and crossbeam towards the field, shall not be less than 70 centimeters and shall not exceed 120 centimeters. In addition, a center circle will be set up within the venue, with the center of the field as the center and a radius of 9.15 meters drawn.

Starting from the ground of the court, the net post is 1.55 meters high and must be firmly perpendicular to the ground, keeping the net tightly pulled. At a distance of 0.76 meters from the end line, draw a horizontal line parallel to the end line, which is called the front serving line. In the doubles court, the area formed by two parallel lines from the end line to 0.76 meters inside the court, connected to the two sideline lines, is the doubles serve line.

Facilities
