We've compiled over 40 articles to help you buy and size the right baseball or softball bat. Much of our empirical work falls in the category of the bat metrics section which take a close look a bat exit speeds, bat swing weights and barrel sizes. If this is your first time buying a serious bat then we suggest you start at the top and start moving downwards.

What Size Bat?


See the Full Size Chart

There are several bat size charts out there, but few actually give us the information we are looking for. That is, the actual WEIGHT of the bat we should be looking for. Telling us the length of the bat, considering the number of drops in the baseball and fastpitch space, is nearly useless. The above fitting size chart uses formulas derived in a lab to determine maximum impact at collision.

See Our Exit Speeds

We discuss the exit speeds we gather in most of the reviews we write. You can find some of the speeds on our article called the Hottest Bats. There, we’ve measured no less than 60 different bats for their exit speeds during cage work over 2,000 different swings and 4 different hitters and report the top results. It stands as the largest ball exit speed test ever performed for consumers.

We also sell access to the entire spreadsheet of work which includes every swing and the metrics associated with each bat we test.

How Much Should I Spend Bat | The Rule of Age

We made up a formula that seems to work to dicide the maximum amount you should spend on a bat. We call it the age rule. Ultimately, we multiple the age of the player by the number of games they'll be playing with the bat. The result is the most you should spend on a bat.

For example, a 10 year old playing 20 games this year should spend no more than $200 on a bat. A 14 year old playing 50 games should reasonably play $700 on a bat. Of course there is no such thing as a $700 bat, but the principle is at 14 playing 50 games the player would be justified in buying any bat on the market.
