A cricket ball weights between 5 1/2 and 5 3/4 ounces for men's cricket, according to Lord's. The ball must also measure between 8 13/16 and 9 inches in circumference.
Cricket balls can vary slightly in weight to accommodate the production process. Typically, cricket balls are made from cork that has been covered by leather. The regulation of cricket ball manufactures is stringent in order to maintain the size and weight limits for the sport.
Because of the weight of cricket balls, they are known for being potentially injurious when thrown at high speeds. British Standard BS 5993 is the piece of legislation that regulates the size and weight of cricket balls.
