A baseball bat is a long, cylindrical tool used in the sport of baseball to hit the ball. Typically made from wood or metal, bats come in various lengths and weights to suit different players' preferences. The standard length for adult bats ranges from 30 to 34 inches, while youth bats are generally shorter. The design of a baseball bat includes a thick handle for grip and a wider barrel for striking the ball. Regulations set by organizations like Major League Baseball dictate the maximum dimensions and materials allowed for bats used in official games.
