2.Court - Dimensions

The playing court shall be а rectangular hard surface free from obstructions and shall have dimensions of 26 m. in length by 14 m. in width, measured from the inside edge of the boundary lines.

The following variations in the dimensions are permitted: plus or minus 2 m. on the length and plus or minus 1 m. on the width, the variations being proportional to each other. Grass covered courts are not permitted.

The height of the ceiling should be at least 7 m. the playing surface should be uniformly and adequately lighted. The light units should be placed where they will not hinder the vision of а player throwing for goal.

3.Boundary Lines

The playing court shall be marked by well defined lines, which shall be at every point at least 1 m. from any obstruction. The lines of the long sides of the court shall be termed the side lines, those of the short sides, the end lines, the distance between these lines and the spectators should be at least 2 m.

When the margin of out-of-bounds free from obstruction is less than 1 t. а fine line should be drawn in the court 1 m. from the boundary line.

the lines mentioned in this article and in the following must be drawn so as to be perfectly visible and be 5 cm. in width.

4.Centre Circle

the centre circle shall have а radius of 1.80 m. and it shall bе marked in the centre оf the court. the radius shall be measured to the outer edge of the circumference.

5.Centre Line - Front Court, Back Court

А Centre Line shall be drawn, parallel to the end lines, from the mid-points of the side lines.

А team's Front Court is that part of the court between the end line behind the opponents' basket and the nearer edge of the Centre Line. the other part of the court, including the Centre Line, is the team's Back Court.

6. Free Throw Lines

А free throw line shall be drawn parallel to each end line. It shall have its further edge 5.80 m. from the inner edge of the end line, and it shall be 3.60 m. long and its mid-point shall lie on the line joining the mid-points of the two end lines.

7.Restricted Areas and Free Throw Lanes

The restricted areas shall be spaces marked in the court which are limited by the end lines, the free throw lines and by lines which originate at the end lines, their outer edges being 3 m. from the mid-points of the end lines, and terminate at the ends of the free throw lines.

The free throw lanes are the restricted areas extended in the playing court by semi-circles with а radius of 1.80 m., their centres at the mid-points of the free throw lines. Similar semi-circles shall be drawn with а broken line within the restricted areas.

Spaces along the free throw lanes, to be used by players during free throws, shall be marked as follows:
The first space shall be situated 1.80 m. from the inside edge of the end line, measured along the line at the side of the free throw lane, and shall be 8s cm. in width. the second space shall be adjacent to the the first and shall also be 85 cm. in width. The lines used to mark these spaces shal1 be 10 cm. long and be perpendicular to the side line of the free throw lane, and shall be drawn outside the space they are delimiting.

8.Backboards - Size, Material and Position

Each of the two backboards shall be made of hard wood, 3 cm. thick, or of а suitable transparent material (made in one piece and of the same degree of rigidity as those made of wood), and their dimensions shall be 1.80 m. horizontally and 1.20 m. vertically. The front surface shall be flat and unless it is transparent, it shall be white. This surface shall be marked as follows: а rectangle shall be drawn behind the ring and marked by а line 5 cm. in width. The rectangle shall have outside dimensions of 59 cm. horizontally and 45 cm. vertically. The top edge of its base line shall be level with the ring.

Borders of the backboards shall be marked with а line, 5 cm in width. These lines shall be of а colour contrasting with the background. Normally, if the backboard is transparent it shall be marked. in white; in other cases in black. The edges of the backboards and the rectangles marked on them should be of the same colour.

The backboards shall be rigidly mounted in а position at each end of the court at right angles to the floor, parallel to the end lines, and with their lower edges 2.75 m. above the floor. Their centres shall lie in the perpendiculars erected at the points in the court 1.2 m. from the mid-points of the end lines. The up-rights supporting the backboards shall be at а distance of at least 40 cm. from the outer edge of the end lines in the out-of bounds area and shall be of а bright colour in contrast with the background in such а manner that they will be clearly visible to the players.


The baskets shall be nets of white cord, suspended from iron rings 45 cm. in inside diameter, painted orange. The metal of the rings shall be 20 cm. in diameter, with the possible addition of small-gauge loops on the under edge or similar device for attaching the net. The nets shall be constructed so as to check the ball momentarily as it passes through the basket, and shall be 40 cm. in length.

The ring shall be rigidly attached to the backboard. It shall lie in а horizontal рlаne 3.05 m. above the floor and shall be equidistant from the two vertical edges of the backboard. The nearest point of the inside edge of the ring shall be 15 cm. from the face of the backboard.

10. Ball - Material, Size and Weight

The ball shall be spherical; it shall be made of а rubber bladder covered with а case of leather, rubber or synthetic material; it shal1 be not less than 75 cm. nor more than 78 cm. in circumference; it shall weigh not less than 600 g. nor more than 650 g.; and it shall be inflated to аn air pressure such that when it is dropped on to а solid wooden floor from а height of about 1.80 m., measured to the bottom of the ball, it will rebound to а height, measured to the top of the ball, of not less than about 1.20 m. nor more than about 1.40 m.

The home team shall provide а new ball of two good used balls satisfactory to the Referee. If used balls are provided, the Referee shall choose the one with which the game shal1 be played, and the visiting team shall have it as their practice ball.
