Bat Sizing

Bat Chart*

Success at the plate often comes down to this: making consistent hard contact against live pitching. To do this, it’s important to swing the right bat for you. That means a bat that’s long enough to cover the strike zone, light enough to swing with ease, heavy enough to generate power, and, of course, permitted in your league. In order to find the ideal size for you, consider the following guidelines:

Bat length is measured in inches from knob to end cap. A longer bat gives you greater reach, allowing you to hit balls on the outside part of the plate. However, longer bats also tend to have more mass towards the end of the bat that requires more power to swing them. We recommend swinging bats of different lengths to decide what option best suits your swing. The right combination of length and weight will help you reach your peak performance. Read More ...


Bat weight is measured in ounces (oz.). A bat’s weight is often tied to its “weight drop” -- its length in inches versus its weight in ounces. For instance, a 32-inch, 22-ounce bat would be referred to as a -10 bat. Read More ...


*This is a recommendation. The best way to find the right size bat for you is to demo them, preferably against live pitch speeds.
**Manufacturing tolerances, performance considerations and grip weight may cause variations from the listed weight.



Governing bodies (for example, the USSSA) set unique standards for bat performance. Bat manufacturers make bats to meet these standards. Each standard, however, is different. So, bats meeting one standard may not meet another. Bats are marked with logos identifying the standard which they meet.

Leagues adopt the standards they deem appropriate for play under their particular rules. League adoptions vary region by region, so we highly recommend consulting your coach and/or league official to understand the standard adopted by your league prior to purchasing a new bat.

The following information will help you understand in the standard adopted by your league:

There are five major governing bodies for fastpitch softball. They are Amateur Softball Association (ASA), United States Specialty Sports Association (USSSA), Independent Softball Association (ISA), National Softball Association (NSA), and International Softball Federation (ISF).

These logos can be found on bats, and certify that the bat is legal for certain leagues and tournaments. Please check with your coach/league for details on what bats are approved.



A bat is more than just a hunk of metal or wood. It is a carefully-engineered tool that allows players to get the most out of every swing. Every component of the bat, from the knob to the end cap, is designed to maximize every ounce of performance. There are four main tech components you need to know for your bat: Material, Construction, Barrel Diameter and Weight Balance.


One of the biggest influences on bat performance is its material. Traditionally in Fastpitch, bats are made from composite or alloy materials. Please read below to learn more about bat materials and how they affect performance.

Composite Vs. Alloy

Non-wood bats are built from either alloy, composite, or a combination of the two.


Composite bats are made with a layered material (often carbon fiber) that is easy to distribute, giving us the ability to make bats with a variety of swing weights, from balanced to end-loaded.

Pros of Composite:

  • Minimize the sting from a mis-hit ball by reducing vibration to the hands

  • Often have a larger sweet spot than alloy bats



Alloy is a mixture of two or more metals, and has been commonly used Fastpitch bats for years.

Pros of Alloy:

  • Stiffer feel through the swing zone

  • More durable material



One-piece bats are one complete piece of composite or alloy and are often used by power hitters, since they provide less flex on contact.

Two-piece bats are comprised of two separate parts: the barrel and the handle. The handle is connected to the barrel through a transition piece in the taper area of the bat. Two-piece construction helps minimize vibration on mis-hit balls. Those bats are preferred by contact hitters, since the two-part construction helps generate maximum swing speed without the fear of major sting on contact.

Barrel Diameter

The barrel is the thickest and widest part of the bat used to hit the ball. The barrel is where you want to hit the ball in order to achieve maximum performance.

Barrels come in different sizes, and are measured by diameter. Barrel diameter is measured in inches and, like weight drop, certain leagues limit the size of a bat’s barrel. Please refer to the Leagues section on what your league requires. Generally, Fastpitch bats are 2 14 inches.

Swing Weight

A factor you may not see, but will definitely feel is the swing weight* of your bat. Bats are often segmented by their given length and weight. The Swing weight is a determination of how a bat’s particular weight is distributed along the bat’s length. For example, you can have two bats that are 30 ounces, but that have different swing weights because the 30 ounces are distributed differently in the bat. Bats can fall along the swing weight spectrum, from light to balanced to end-loaded.

End-loaded bats shift extra weight toward the end of the barrel, creating more whip-like action on a player’s swing and generating more power.

Balanced bats have a more even weight distribution, allowing for potentially greater swing speed for many hitters. This is preferred by contact hitters who want more control of their swing.

*Note - there are a variety of swing weights offered to meet player needs.
