BBCOR Swing Weights | Lightest & Heaviest BBCOR

After measuring thousands of exit speeds, we’ve found swing weight as the most important factor in predicted exit speeds. To be sure, swing weight is the most important feature of the bat, but not of the swing. Bat speed, mechanics, and other things that are hitter controlled are more important than the bat. In terms of what the bat can control the swing weight, not barrel performance, is the single most important factor in predicting and improving exit speeds.

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.

Get the BBCOR Swing Weights We Only Send Our Email Subscribers

Measuring swing weights is a colossal and expensive task. To measure the bats, we need to own them. It also takes time to find the balance point, scale weight, and pendulum period of the bat. As well, the formula for measuring swing is not uncomplicated.

We share our swing weights with our email subscribers. These include all the swing weights from every year and every league. Once subscribed, you’re given access to a page with all the swing weights and is updated every 60 days or so.

What You Can Tell With Swing Weights

  1. The Lightest BBCOR Bat. If you’re in search of the lightest swinging BBCOR bat, then swing weight is what you want to know. Our data list, which is often updated, will show you the lightest swinging BBCOR bats (and the heaviest too).
  2. Similar Swinging Bats. The greatest utility gained from knowing the swing weights of most BBCOR bats is you’ll be able to tell how bats from other brands, models, and years swing in relation to each other. So, if you know a certain bat is a bit too light or too heavy, the aggregated swing weight list will get you in the right place to get the perfect bat.

Standard Errors and Accuracy

Although we are confident in our swing measurements’ repeatability, we do not submit they are perfect. Our best estimate is we run no less than 200 points off. Meaning, a percentage swing of 2 to 3%, either way, would be a reasonable margin of error.

A percentage point or two one direction or another is virtually indistinguishable to any given player. A bat with a 4% change in any given direction on the above chart is likely not noticeable by anyone.

Why does the price go up whn ther bat is pretty much the same ?

So does swing weight translate to wood bat turn models? With wood bats I am used to seeing balanced defined as a 110 turn, a little end loaded defined as a 271, and a lot end loaded defined as a 243. Do these wood turn models correlate to swing weight in this evaluation?

When buying a wood bat, the 271 and 243 turn models get marketed to power hitters or hitters looking for more power. Where as with composite bats it seems like the marketing hype is all about being “balanced” which sounds like a 110 turn to me.

How does the Marucci Posey BBCOR rank in among these bats?

Thank you for putting up this info. It is super helpful and, as you know, pretty much impossible to find anywhere else.
Would you be willing to include a link to the 2018 swing weight data you had previously posted? It would be interesting to compare between years.
Thank you!

Little confused. You said the axe avenge is the lightest swinging bat. But then it’s not listed under The Lighedt Swinging BBCOR Bat. Please clarify thanks!

Why are the values for the 2018 bats different from the 2019 bats? Would be nice to be able to compare the two lists.

Where is the CAT 8 on this list? It is a popular bat and was redesigned to have a lighter swing weight than the CAT 7. Would like to be able to compare.

618 Solo is the perfect bat for a smaller player transitioning to BBCOR. We have a 31/28, my son loves it. Super light, great pop. We also picked up a 917 Prime 32/29 in case he shoots up. (fingers crossed)

Can you publish these same tables for USSSA bats in both the -8 and -5 categories? Would really be helpful since the BBCOR and USSSA bat of the same model name could be very different and fall into the table very differently. Would greatly appreciate it!

Any idea what the swing weights are for the 2021 33″ voodoo one or the 2021 33″ stinger nuke?

I like your swing weight analysis on this site. This is especially helpful for smaller, lighter weight players. Can you tell me where the Easton ADV 360 and the Warstic Bonesaber fall on your 2020 swing weight bar chart? Looking at these plus Easton Maxum and Victus Vandal for a 5’8″ 122 lb. contact high school player. He is moving up to a 32″ this coming season. Would you have a specific recommendation? This player already has a 2015 Easton Mako that is like new. We’re not sure if the newer BBCOR’s will perform better than this Mako. The swing weight of the Mako is good, very light, but not sure how it will perform with live pitching. I like to provide two bats for my son, usually a composite and an alloy for colder days. Although, I’ve never seen anyone crack a composite in lower temperatures. I know… lots of questions, right? Thanks

So I subscribed and didn’t get a list so how exactly do I see the data on swing weight

So if I’m reading the chart correctly the cat7 has a very high swing weight. What bat would you suggest for a 14u player and he has used the cat 7 for a year and his average has dropped off and he developed other issues in his mechanics. I believe because he is smaller (100 lbs) it is related to the swing weight of the cat 7

If your son is 100 lbs., look for a good condition used Easton Ghost X or an Easton Mako 2015 white/orange. He will benefit from the 2 piece composite. In my experience, with these bats, you will have a bigger sweet spot than a SOLO. Also, the ball flies off of theses bats further and harder than a SOLO for lighter/smaller players. They both have low swing weights. The other benefit… no hand sting/vibration. An Easton S1 2011 is also a popular used 2 piece comp. bat… 31/28. Ask the seller questions and study the pictures, end cap and knob to judge condition and usage. I’ve seen many players struggle with the Cat 7 and 8. Cat 6 swings lighter in my opinion and still hits well, and is less bulky.
If you don’t mind buying new expensive bats, the Easton Maxum 1 piece comp, Combat B2 one piece comp, Victus Vandal alloy, maybe Demarini CF Zen 2 piece comp. are light swinging, popular bats to check out.

So I’ve been looking at the swing weight chart. If we are swinging a light 32 inch bat and in the next year or so want to get to a light 33 inch bat would it make sense to move to more of a middle of the road 32 in between there? Thinking about the meta or the maxxum ultra?
