All About Swing Weights
How do you determine a bats swing weight??
What does the minus number mean??
How much does a 32" -9 weight??
Hopefully our simple explanation below will make sense of
The minus number (-9, -12, -10, etc...) represents the weight of the bat
relative to the length. So how much does a 32" -9 bat weigh? Take 32,
subtract 9, and you've got your swing weight: 23 ounces. Simple right?
How about a 34" -12 bat? Take 34, subtract 12, and you've got a swing
weight of 22 ounces.
It's very common for bat manufacturers to create several models with
varying weight/length ratios. For example the popular DeMarini CF4
Fastpitch Bat is
manufactured in a -8, -9, and -10 model, that way you are almost
guaranteed to find the length/weight combination that's right for you.
It's also common for bat manufacturers to create varying swing weights
of a certain bat length. Take the 34" DeMarini Juggernaut for example - It's a
34" bat made with a swing weight of 26, 27, 28, or 30 oz. The choice is
up to you.
So if a bat has a standard -9 to it, you will know the swing weight (in
ounces) is always 9 less than the length. If there is no drop number
assigned to the bat, then there is probably more than one swing weight
available for each size.
