Basketball is one of the most popular sports in the world. It is usually played indoors and consists of two five player teams. The object of the game is to score goals through one of the two baskets.
The playing court shall have a flat, hard surface free from obstructions (Diagram 1) with dimensions of twenty-eight (28) m in length by fifteen (15) m in width measured from the inner edge of the boundary line.
A team's backcourt consists of its team's own basket, the inbounds part of the backboard and that part of the playing court limited by the endline behind the team's own basket, the sidelines and the centre line.
A team's frontcourt consists of the opponents' basket, the inbounds part of the backboard and that part of the playing court limited by the endline behind the opponents' basket, the sidelines and the inner edge of the centre line nearest to the opponents' basket.
The playing court shall be limited by the boundary line, consisting of the endlines and the sidelines. These lines are not part of the playing court.
Any obstruction including seated team bench personnel shall be at least two (2) m from the playing court.
Centre line, centre circle and free-throw semi-circles
The centre line shall be marked parallel to the endlines from the mid-points of the sidelines. It shall extend 0.15 m beyond each sideline. The centre line is part of the backcourt.
The centre circle shall be marked in the centre of the playing court and have a radius of 1.80 m measured to the outer edge of the circumference. If the inside of the centre circle is painted, it must be the same colour as the restricted areas.
The free-throw semi-circles shall be marked on the playing court with a radius of 1.80 m measured to the outer edge of the circumference and with their centres at the mid-points of the free-throw lines (Diagram 2).
Free-throw lines, restricted areas and free-throw rebound places
The free-throw line shall be drawn parallel to each endline. It shall have its furthest edge 5.80 m from the inner edge of the endline and shall be 3.60 m long. Its mid-point shall lie on the imaginary line joining the mid-points of the two (2) endlines.
The restricted areas shall be the rectangular areas marked on the playing court limited by the endlines, the extended free-throw lines and the lines which originate at the endlines, their outer edges being 2.45 m from the mid-points of the endlines and terminating at the outer edge of the extended free-throw lines. These lines, excluding the endlines, are part of the restricted area. The inside of the restricted areas must be painted in one colour.
Free-throw rebound places along the restricted areas, reserved for players during free throws, shall be marked as in Diagram 2.
Three-point field goal area
The team's three-point field goal area (Diagram 1 and Diagram 3) shall be the entire floor area of the playing court, except for the area near the opponents' basket, limited by and including:
- Two (2) parallel lines extending from and perpendicular to the endline, with the outer edge 0.90 m from the inner edge of the sidelines.
- An arc of radius 6.75 m measured from the point on the floor beneath the exact centre of the opponents' basket to the outer edge of the arc. The distance of the point on the floor from the inner edge of the mid-point of the endline is 1.575 m. The arc is joined to the parallel lines.
The three-point line is not part of the three-point field goal area.
Team bench areas
The team bench areas shall be marked outside the playing court limited by two (2) lines as shown in Diagram 1.
There must be fourteen (14) seats available in the team bench area for the team bench personnel which consists of the coaches, the assistant coaches, the substitutes, the excluded players and the team followers. Any other persons shall be at least two (2) m behind the team bench.
The two (2) lines of 0.15 m in length shall be marked outside the playing court at the sideline opposite the scorer’s table, with the outer edge of the lines 8.325 m from the inner edge of the nearest endline.
No-charge semi-circle areas
The no-charge semi-circle lines shall be marked on the playing court, limited by:
- A semi-circle with the radius of 1.25 m measured from the point on the floor beneath the exact centre of the basket to the inner edge of the semi-circle. The semi-circle is joined to:
- Two (2) parallel lines perpendicular to the endline, the inner edge 1.25 m from the point on the floor beneath the exact centre of the basket, 0.375 m in length and ending 1.20 m from the inner edge of the endline.
The no-charge semi-circle areas are completed by imaginary lines joining the ends of the parallel lines directly below the front edges of the backboards.
The no-charge semi-circle lines are not part of the no-charge semi-circle areas.
