Bocce balls come in a variety of sizes ranging from 80 mm all the way to 115 mm. The “size” refers to the diameter of the Bocce ball, with the measurement referring to the width of the ball. An 80 mm ball means that the ball is 80 millimeters wide. Since the balls have uniform consistency and weight, the weight will increase with the width of the ball.
International Standard/Tournament Regulation Balls: The International Standard ball used in international play is the 107 mm (4.2 inches) ball weighing 920 grams, or about two pounds. The Pallino/Jack, which is less important, has no official regulation size but the International Standard size is 40 mm.
What size should you get? If you’re a recreational player, any size between 100 mm and 110 mm will do. Children may find it easier to use a smaller ball, under 100 mm, and tournament players probably want to use between the regulation 107mm and the maximum of 115 mm. As for Pallinos, the only recommendation is that you get a larger one if you play on lawns so that you can see it in taller grass.
