In addition to bat length, you will also need to determine your bat weight or “drop.” Your drop is the difference between a bat’s length and its actual weight. For example, if your bat measures 32 inches long and weighs 22 ounces, it would have a drop of -10. As an equation, it would look like this:
(Bat length in inches) - (bat weight in ounces) = Drop
The bigger the drop, the lighter a bat will be. It’s important to know your league’s bat drop regulations. At the high school and collegiate level, bat drop is regulated, as players cannot use a bat with a drop over -3.
