This chart is nothing more than an approximation of what size bat a player may need. When selecting a bat, you should take in to consideration your comfort level with the size you are currently swinging. Also take in to account that much of the process of picking the perfect bat is personal preference. Many players like a heavier bat for more power, while others like to swing a lighter bat to gain more control and bat speed. If you have absolutely no idea what size to select, try some of your teammates' bats. Experimenting with swinging different sizes allows players to compare and contrast what they like and what sizes they can properly handle.
