So, let us dive deeper into the purpose of bat numbers and what they signify.

The Purpose and Significance of Bat Numbers


Just like stated earlier, the numbers on the bat play a big role in the sport of baseball. The attached negative number on a bat signifies if it is a match with the player’s weight and height. Apparently, the digits entail even the baseball hitter’s drop weight, speed, and other data.

In addition, the purpose of the numbers will also tell the mixed markers in the bat’s weight, in ounces, and length – all in metric inches. It is also known as the drop weight. This is the negative (-) number on the bat and states the length-weight ratio of the baseball bat.

Now, let’s talk about “weight drop.”

How is the Weight Drop Calculated?


Weight drop or drop weight is an important metric calculation in baseball. Aside from showing the detailed contrast of your gaming bat, it also serves as your guide, ensuring that you will be cozy using it.

For starters, knowing how much your bat weighs will make it easier for you to know which bat is perfect for you to use in the game. You might have seen these numbers when looking at bats: -4 oz., -5 oz, -7 oz, -8 oz. But what does it mean?

How this is calculated is you take the weight of the baseball bat in ounces and deduce it by the length of the bat in inches. For clarity, you can check the formula here:

Formula of the Baseball Drop Weight

(Weight of the Baseball Bat in Ounces) – (Length of the Baseball Bat in Inches) = (The Drop Weight)

Example: 12 oz – 20 inches = – 8 (this is the drop weight of your chosen bat)

In this formula, minus 8 is the result you get. The minus sign means that the bat is lighter than its length.

Needless to say, if the results are 0, it means there is no difference between the weight and length of the bat.

Determining the Perfect Baseball Bat Number


You should pay attention to three points before buying a baseball bat. And since you learned about the formula, the factors within it are almost the same.

We have rounded them up for you. These are:

  • Arm length or Height. These should match the player’s body form. Extra attention should be paid if you are buying for children. Taking into account their body growth can save you time and money going to buy a new bat.
  • Weight. Another factor that should affect your decision because it will determine the drop and swing.
  • The Measurement of your Chest to Fingertips. With this, you will know which bat can parallel your dimensions.

The following points are the main ones that affect the drop number on bats. Now, the other factors that you should consider:

  • The Bat Material. In shopping for the right bat, you also need to see the materials used.
  • The Barrel Size. This is the largest part of the bat. Thus, it will affect the bat’s number since it determines the bat’s speed.

Know that the smaller the size of the barrel, the lighter it is – making it faster to swing during the game.

  • The Taper of the Bat. On the other hand, this is the size of the handle. It is the overall weight of the bat. Its standard measure is 31/32 inches.
