Baseball Bat Length

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 which requires more power to swing them. The right combination of length and weight will help you reach your peak performance.

Baseball bats are most commonly found between 24-34 inches. Please check the size chart for examples of what length may be appropriate for you.

Baseball Bat Weight

As a general rule of thumb, the higher the competition or league level (meaning, from youth league up to the pros) the lesser the weight drop. A lesser weight drop means the bat feels heavier. So a -5 bat will feel heavier than a -10 bat.

Selecting the right bat weight depends on three main factors: sport, league rules, and player preference.

  • Leagues have rules identifying which weight drops are permitted for play. Before choosing a bat, we recommend determining if your league has a specific standard for bat weight drops for them to be permitted. Please refer to the Your League section for more information on league rules.
  • Players with less experience generally swing lighter bats in order to have better bat control. More experienced players generally swing a heavier bats to help maximize power. A way to tell if a bat is right for you is your swing speed. A bat that is too heavy is harder to swing, causing a loss in momentum, reduced distance or a miss altogether. If a bat is too light for a player, the player could miss out on the extra force they could generate from a heavier bat. A happy medium needs to be found. It is highly recommended you demo a bat against live pitching speeds in order to find the best weight for you.

Most common weight drops in various baseball leagues are -12, -10, -9, -8, -5, and -3. As you progress toward high school baseball, the weight drop lowers (the bats become heavier). When moving to a heavier bat, you may then decide to drop an inch in length to more easily handle the additional weight. This is a matter of personal preference and comfort at the plate as you advance in age, league and skill level.

Baseball Bat Sizing: Weight Drop explained

A Baseball Bat weight is measured in ounces (oz.). A bat’s weight is connected to its weight drop, meaning its length in inches versus its weight in ounces. For instance, a 34-inch, 24-ounce bat would be referred to as a -10 bat.


Baseball Bat 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. These are the most common barrel diameters:

  • 234 inches
  • 258 inches
  • 214 inches
