Step 1
Know your league's rules. Do you use wood or metal? How big can the barrel of the bat be? Is there a certain ratio between a bat's weight and its length that must be followed? You can find out all of these answers by consulting your league's commissioner or perhaps your coach.
Step2
Set your budget. Bats can range anywhere from $25 to $300. Make sure not to use your shiny new investment in batting cages. The balls there are often harder than traditional game softballs.
Step3
Pick up and feel a friend's bat to get a proper idea on what weight or size you're looking for. There is no full-proof way to measure what size softball bat is best for you. Keep in mind how the bat feels in the store and how it will feel at the end of the game.
Step4
A bat should be light. Bat speed generates power. This holds true for a pitcher as well where arm speed is the main determinant for velocity. Grip the bottom part of the handle with just one hand. Hold the bat directly in front of you and lift the bat 6-8 times using only your wrist. If you have to bend your arm/elbow in order to lift the bat then it would be in your best interest to select a lighter bat.
Step5
Young players tend want longer bats because they feel that they can reach the other side of the plate; while keeping there distance from the ball. A bat that is too long can make hitting a softball one of the hardest things you'll ever try. Control and comfort is the best combination.
Step 6
Buy for this season. There's a rumor that a young player should select a bat that "he can grow into." The problem is a young player has a hard time hitting the ball, and this can discourage them for future play. Buy for the now to give you the best chance for success the first time around.
