Use Our Baseball Bat Weight Charts by League

We created the following baseball bat weight size charts for popular age brackets and baseball leagues. Each player's strength and swing speed will differ, so use these charts as a guide.

Before we proceed, you’ll need to know how weight impacts your bat size. Drop and length on bats to ounces is what is known as ‘bat drop’. For example, a bat that weighs 20 ounces and is 30 inches long will have a drop of -10.

What Does Bat Drop Mean?

Baseball bat drop is the difference between the length of the bat (measured in inches) and the weight of the bat (measured in ounces). Use this easy formula when you need to calculate your bat’s drop: Bat Length - Bat Weight = Bat Drop.

Lower Bat Drop

  • Older or stronger players usually favor lower drop weights, which offer increased power.
  • The older you get, the weight drop lowers and the bats get heavier.

Higher Bat Drop

  • The higher in number the drop weight, the lighter the bat.
  • Younger or weaker players can benefit from higher drop weight, which helps improve bat speed.

What Size Baseball Bat Do I Need?

Bat size consists of bat length, weight, and drop measurements. Bat length affects your swing mechanics and plays a major part in the way that you cover the plate. You can find the right length for you with a simple three-step measuring technique using your body.

Getting the Right Baseball Bat Length

The right baseball bat length depends a lot on personal preference. A too-long bat may also be too heavy, which can impair your swing speed. Take multiple swings. If the bat feels heavy, you’ll likely need a shorter bat length that weighs less, too.

  • When using a heavier bat, you may want to drop an inch of length from your bat to get a better handle on the extra weight.

  • Weight distribution along the bat's length may also vary slightly, which you'll feel as you swing your bat.

  • Bats with most of the weight loaded at the end of the barrel will generate more power with a whip-like swing action.

  • Bats with an evenly distributed weight will generally give the hitter more control and overall swing speed.

Determine the Best Bat Weight

  • Hold the bat by the grip with your arm extended to your side for 30–45 seconds. If this feels like a challenge, your bat is probably too heavy for you.

  • When you’re up to bat, if you’re dropping your bat and swinging “up,” you may need a lighter bat. If you’re swinging across the plate before the ball gets there, you may need a heavier bat.

Measure Yourself for an Accurate Baseball Bat Size

To find the correct baseball bat length for you, use your body to measure the fit in three steps:

Measure with Your Arm

Step 1: Measure with Your Arm

  • Place the knob of the bat in the middle of your chest and extend one arm to the side.

  • Your bat is sized correctly if the end of the barrel is even with your knuckles.

  • If the end cap touches your wrist or palm, the bat is probably too short.

  • If the end cap extends beyond your fingers, it is probably too long.

Measure from Your Chest

Step 2: Measure from Your Chest

  • Position the knob of the bat in the center of your chest.

  • Hold the bat out perpendicular to your body and parallel to the ground

  • If you can reach the base of the barrel with your fingertips, the bat is the right length for you

Measure Standing Up

Step 3: Measure Standing Up

  • Stand the bat next to you with the end cap on the ground.

  • If you can reach the knob with the center of your palm, then the bat is probably the correct length.

Expert Tip:

This measuring technique works for adults as well as youth players with one exception. When standing the bat up next to your child, if the bat falls near their hip, it is correctly sized.

Understanding the Anatomy of a Baseball Bat

A standard baseball bat for both kids and adults alike can be broken down into six main areas: the handle, knob, grip, taper, barrel, and cap. Bat length is measured in inches from the knob to the cap.

If you’re brand new to baseball, you might not know the general design of a baseball bat. Use the following graphic to help you navigate measuring yourself for the best bat length:

Expert Tip:

The longer the bat, the more plate you’ll cover but the heavier the bat will be. The heavier the bat, the more power you’ll need to swing the bat.

Different Types of Baseball Bats

Baseball bats vary on how they’re constructed and what material they’re made of. The type of bat you choose depends on:

  • 1: Your league’s regulations

  • 2: Your personal preference for the bat’s fit and feel

Baseball Bat Construction

One-Piece Bats

Marucci CATX 2023 BBCOR Baseball Bat
  • One-piece bats are made of one, continuous piece of material throughout.

  • This type of construction makes for a stronger bat with more balance — making it a great option for beginner baseball players.

  • One-piece baseball bats demand more power to hit the ball further. They also tend to vibrate more on contact with the ball.

Two-Piece Bats

  • Two-piece bats are constructed by fusing a barrel and handle together at the end of the manufacturing process.

  • This split design can provide more flex on contact with the ball and less vibration — making them a good option for players who want to avoid that stinging feeling when they hit the ball.

  • You may also feel more ‘whip’ in your swing with a two-piece bat, giving you more speed and power.

You can find three-piece bats, too! Similar to the two-piece bat construction, a bat with ‘three pieces’ simply means that the bat is made with three different metals. This offers players the opportunity to swing with a more evenly distributed weight. You’ll find these bats often feel lighter and allow for a quicker swing.

Baseball Bat Materials

Alloy Bats

  • Alloy bats are durable and come ready for use.

  • No break-in period, along with their affordability, makes them a great choice for training.

  • Although they have a smaller sweet spot than other materials, their ability to withstand any temperature means how you hit the ball won’t change with the weather.

Wooden Bats

Victus Sports Pro Cut Wood Bat
  • Wood bats are the most popular type of bat and offer the best balance for a more controlled swing — although they do lack the power and durability of an alloy bat.

  • They are most often made of ash, maple, or birch wood.

  • Because varying wood types can yield a variety of overall bat quality, wood bats often have a drop weight of 3 to standardize purchasing.

Composite Bats

Demarini The Goods One Piece SL 2022 USSSA Baseball Bat
  • Composite baseball bats are crafted with materials such as reinforced carbon fiber polymers that reduce vibration and tend to have larger sweet spots.

  • They can put a lot of pop and power behind your swing and are good for reducing the sting felt by making poor contact.

  • They’re more expensive than other types and typically require a break-in period of about 150-200 hits. They’re also temperature-sensitive and not recommended to use in weather colder than 65°F.

Hybrid Bats

Axe Avenge Pro 2022 Hybrid Bat
  • Hybrid bats are crafted from a blend of aluminum alloy and composite components working in tandem. These baseball bats deliver the best characteristics of alloy and composite bats.

  • They typically utilize the composite handle’s knack for reducing vibration and complementing it with the alloy barrel’s no break-in period feature.

  • They’re also comparably lightweight but on the more expensive end of types of bats.

Expert Tip:

Always check with your league’s regulations to confirm your type of bat is legal for play.

Baseball Bat Certifications + League Regulations

The three most common governing bodies for bats are USABat, BBCOR, and USSSA. You’ll see these logos stamped usually on the barrel of approved bats.

No matter your age or skill level, every baseball league follows equipment regulations. Check with your coach and/or league official to make sure your bat meets league requirements.

Tee Ball Bat Standards

  • T-ball bats for players have their own standards.

  • Bats approved by USABat must be 24-26 inches long.

  • Players who use Tee Ball bats are between 4-7 years old.

  • Learn more about Tee Ball bat standards.

USSSA Standards

  • USSSA provides energy transfer bat regulations for leagues governed by USSSA.

  • Standards were set in 2005 and are mostly used for on-the-go tournaments.

  • Eligible bats need a 1.15 BPF-certified thumbprint stamp on their taper.

  • Players ages 7-13 use USSSA bats.

USABat Standards

  • This standard creates a more uniform wood-like bat performance in youth bats.

  • USABat still allows players between 7-13 years old to swing lightweight models, too.

  • Bat models older than 2018 may no longer be eligible to use on the field.

BBCOR Standards

  • This body governs high school and collegiate ages between 14-18 years old.

  • These standards permit bats with a drop of -3 or less at these levels.

  • Bats with a BBCOR stamp are either wood or perform like wood.

Expert Tip:

BBCOR and USABat baseball bats have a similar design, but the latter are usually lighter and therefore easier for younger players to swing.
