THE BALL
The ball is round and the outer casing should be either leather, rubber or other suitable synthetic material. Its circumference should be between 75 and 78cm (29.5 and 30.25 in) and its weight between 600 and 650gm (20 and 22oz). It should be inflated to a pressure so that when it is dropped from a height of 1.8m (6ft) (measured from the floor to the bottom of the ball) on to the playing surface, it will rebound to a height of between 1.2 and 1.4m (4ft and 4ft 7in), (measured to the top of the ball).
