Most 9-10 year old players will perform well with a 28-29 inch bat with a -10 drop. Smaller players will want a bat that is shorter and lighter. A longer, heavier bat will be preferred by a larger player. The baseball bat sizing chart at the bottom of this page will assist you in choosing the correct bat selection. Bats that are too big for a player can cause them to lose contact with the ball, which leads to poor eye-hand coordination. Bats that are too small may not have enough power to hit the ball far. However, most kids' bats fall into one of these two categories: too big or too small. The average kid's bat is about 14 inches long, weighs around 15 ounces, and has a drop between -8 and -9.5 degrees. Some kids might want a bat that is a little longer or heavier than the average version. Others may prefer a slightly smaller bat. Either way, bats come in many different sizes and brands. It's important for kids who are new to baseball or softball to get a bat that is appropriate for their size so they can develop good batting skills early on. As kids get older and their bodies grow, they need bats that are either bigger or smaller than the average youth bat. Younger kids may want to get a stick with more drop; while older kids may want one with less drop. Most kids' bats fall into one of these two categories: too big or too small.
