That depends on the length of the bat. The '-11' and '-12.5' are known as 'drop weights' and represent the value of the length of the bat, in inches, subtracted from the weight of the bat in ounces.

If the lengths of the bats are the same, the difference is the '-12.5' bat weighs one and a half ounces less than the '-11' bat. For example, if both bats are 30 inches in length, the '-11' bat weighs 19 ounces (19 - 30 = -11) and the '-12.5' bat weighs 17.5 ounces (17.5 - 30 = -12.5).

By knowing the length of the bat and the drop weight, you can determine the weight of the bat. Simply add the length of the bat to the drop weight. Another example, let's say the '-11' bat is 29 inches in length and the '-12.5' bat is 32 inches in length. To determine the weight of the '-11' bat, add the length to the drop weight (-11 + 29) to find out that the bat weighs 18 ounces. The '-12.5' bat weighs 19.5 ounces (-12.5 + 32).
