USSSA 1.15 Bat Swing Weights | Drop 10 Mass Moment of Inertia

USSSA 1.15 Bat Swing Weights | Drop 10 Mass Moment of Inertia

October 11, 2020 | by | @BatDigest

We’ve measured the vast majority of USSSA swing weights since 2018.

Swing weights are the most determining factor in predicting exit speeds. More critical than barrel performance, model, or brand, the swing weight is what allows players to get the most mass to the ball at the right time. If swing weight isn’t right, the player is leaving distance on the table, or too late to make any impact.

A bat size chart is also a good place to start. But, remember, the stated weight of a bat is not the same as its swing weight. Bats with the same scale weight can be upwards of 10% different in feel.

The trick to successful bat buying is to find the bat with the right swing weight. The good news is that many bats have, roughly, the same swing weight. You can find the bats in the same grouping of on our swing weight charts.

Q: How Do You Measure Swing Weight?

It’s not very simple, unfortunately.

Ultimately, you take need to find the balance point, pendulum period, and scale weight of a bat. Then, you use a physics formula to calculate the swing weight. We have a tutorial on how to do it here.

Q: Is Swing Weight the Weight of a Bat?

No.

Swing weight is a physics measurement that determines how difficult a bat is to swing around its knob. This depends on the bat’s total scale weight, but more so on the distribution of that weight within the bat. Bat’s with very similar scale weights can have very different swing weights because one might have the weight focused around the knob while the other has it in the end cap.
