If you know that the total weight of a bat means virtually nothing when considering the usefulness of it at the plate, then you will want to know what the swing weight is. We show you how to get the swing weight of your calculator.

Calculate your bat’s swing weight with this Spreadsheet:

Video Explanation of the 4 Variables Needed From Below

Step 1: Weigh the Bat = X

The more accurate the better. Use a kitchen scale and keep it in terms of ounces.

Let’s call this variable: X

Step 2: Measure the distance between the knob of the bat and the point at which the bat balances = Y

There are a few way to do this. The simplest way is use a knife edge or, even, your finger. measure the distance from the balance point to the end of the bat. (So, to the outside of the knob knob).

Let’s call this variable: Y

Step 3: Find the pendulum period of the bat = A

This is the most difficult piece to do with consistency. You need to measure the exact time it takes for a bat to make a full swing (back and forth) as it hangs from some type of pivot. Pivots are something you need to create from some stuff at the hardware store. You can also try and create it with your hand like we do in the picture above.

Let’s call this variable: A

Step 4: Measure the difference between the point the bat was pivoting (swinging) on and the end of the knob. That = B.

This measurement should be rather short depending on how you got the answer to #3 above. It is usually less than 1-inch but could be longer.

Let’s call this variable: B

Step 5: Calculate the Swing Weight

In math, your swing weight answer 6 inches from the knob is this:

Sorry, our calculator was down for maintenance for a couple days. But, should be up now. We put it in an excel spreadsheet that you can click on and edit a bit to get the answers.

Can you clarify #4? I think there is a mistake in the wording and Iām not clear what should be measured. Thanks!

Wondering if there is supposed to be an actual calculator on this site under Step 4, as is shown in the video…

It’s up now. New excel spreadsheet! Thanks

hey, where’s how to calculate the numbers in #4?

Its up now. Thanks.

I’m not seeing anything after “Step #4: Calculate The Numbers Like This”.

Hey Kevin,

Sorry, our calculator was down for maintenance for a couple days. But, should be up now. We put it in an excel spreadsheet that you can click on and edit a bit to get the answers.

Can you clarify #4? I think there is a mistake in the wording and Iām not clear what should be measured. Thanks!

the spreadsheet is veiw only

Download it. If we make it editable by the general public then they’ll end up deleting it. š
