Shooter marbles are approximately 3/4" or 19mm in diameter.
Also called the "Boss" or "Taw", the shooter marble is used to play Ringer and other marble games. In official tournaments in the U.S., your shooter must be between 3/4" and 1/2". A player needs only one shooter to play the game. The marbles in this category usually range between 17 - 21mm in diameter. All sizes are approximations and can vary from one marble to the next.
