When selecting the softball bat that is perfect for you, you want to think of three things: length, weight and drop. Measure the length from the knob to the barrel. Place the knob at the center of your chest and extend the barrel out toward your fingertips. If you can touch the end of the bat with your fingertips, the bat is an appropriate size. If the bat extends beyond your fingertips, it may be too long; if it only reaches your wrist it is probably too short.
The weight of the softball bat can change based on your body style. You should select a weight that you are comfortable swinging. Bats that are too heavy will cause your swing to naturally drop, thus creating a swing at an upward angle. This is an indicator of a bat that is too heavy. If you can hold the bat with one hand, with your arm extended to your side, for 30 seconds, the bat is a reasonable weight.
The drop of the bat is the difference between the length and weight of the bat. A lower drop usually indicates a heavier bat. The higher the drop, the lighter the bat. You should always check your league rules, as there are some leagues that limit the amount of drop a softball bat can have. If you purchase a bat with low drop, you may want to balance that with a shorter bat so that you can retain a quick swing.
