The main thing you are looking for is to see if there is a limitation on the length or the weight of the bat. Most leagues have a limit on the "drop." The drop is the difference between the length of the bat in inches, and the weight of the bat in ounces. High school and college leagues have a limit of a -3 drop. So if you have a 32 inch bat, the lightest it can weigh is 29 ounces.

Also high school and college bats are required to comply with what is called the BESR (ball exit speed ratio) rule. This means that the ball cannot exit the bat more than a certain speed, and the barrel of the bat cannot be anymore than 2 5/8."
