All Swing Weights – Get Access

The single greatest database of industry-wide bat measurements.

Access here is to over 400 measured swing weights of baseball and fastpitch bats. The industry uses the “6-inches from the knob” as the standard pivot for a bat’s swing weight. However, the pivot point of swings varies depending on the hitter.

What if My Bat is Not On The List?

If you can find your model and year, just not your size, then there is a good rule of thumb to follow to find your bat’s swing weight. Generally, bat manufacturers increase their swing weight by 10% for every inch they add. So, for example, if a 30/20 had a swing weight of 6500, you could reasonably expect the 31/21 to have a 7100 MOI. (Because, if you didn’t follow the math there, 110% of 6500 is 7100).

If you can find your bat, just not in the correct year, then it is often reasonable to expect the bat’s swing weight not to have changed much from previous or later years. Rarely does a bat company change a bat model’s swing weight by any measurable difference. That said, you may want to check our review of that bat to make sure as we will note it generally.
