So, I will be talking about things to clarify the confusion about the right size charts and others. I hope this will be a great solution to picking the perfect bat with the right bat size.

Bat Anatomy

Before going into the topic, let’s first talk about baseball bat anatomy. The baseball bats consist of different parts that all collaborate with each other.

Whether a softball bat, a baseball bat, alloy bats, wooden bats, or composite bats, all of them have the same parts. They are as follows.

Handle: The handle is the part that batters hold. All power from the batter’s hands to the barrel goes through the handle. Ultimately, the handle connects the batter to the ball to hit in the end.

Knob: The knob is the part that helps to keep the hands stable. This also keeps your hands in place with the grip when you hold the grip. As a result, your hands do not slip down the handle.

Grip: The grip is the rubber object that covers the handle so that you get proper hold ability on the bat’s handle. The grip also provides comfort as they are made of soft materials.

Taper: After the handle to the main barrel part, the bat gets tapered. The part that connected from the skinny handle to the wider part of the barrel’s end is the taper of the bat. The taper helps to generate the power dynamically with the bat.

Barrel: The barrels are the thickest part of the bat. Basically, the barrel is the part that contacts the balls. So, all power that comes to the ball is from the barrel directly.

End Cap/ End: The end cap is the last part of the bat that is combined with the barrel. End caps balance the barrel’s swing weight as well as help control the bat. It helps to add and eliminate the weight of the bat, and bat speed.

Pick the Right-Sized Bat Based on Height and Weight: Bat Size Charts for 3’ to Under 4’ Long Players

There are several attributes are combined when you look for the right-sized bat for you or your kids.

Let’s talk about them one by one.

For a batter who is in between 3′ to 3’4″ and weighs under 60 pounds, a 26-inch bat is ok for him. But, with the same height but weighing 61 to 70 pounds, he would be fine with a 27-inch bat.

A hitter that weighs between 60 and 70 pounds and is between 3’5 and 3’8 in height should be comfortable with a 27-inch bat. However, a 28-inch bat is suggested if the weight is increased from 71 to 100 pounds.

However, parents should choose a 29-inch bat if he is the same height as the child but weighs between 101 and 140 pounds.

When the weight goes over 140 pounds a 30-inch bat would be the right choice.

Now, the height of 3’9″ to 4′ would need some shuffles. Under 60 pounds up to 80 pounds should go for a baseball bat that is 28 inches long. Same height, but weighs up to 130 pounds from 81 pounds, the 29-inch bat is the proper bat size.

Weighs over 130 should go for the 30-inch bat.

A 29-inch bat is advised for players who are between 6 and 90 pounds in weight and between 4’1″ and 4’4″ in height. By doing this, the batter’s bat speed will be balanced. The majority of bat size charts recommend a 30-inch bat for athletes who are the same length but weigh between 91 and 150 pounds.

But, if the batter exceeds the weight of more than 150 pounds up to 170 pounds, should go for a 31-inch bat.

On the other hand, if the length of the batter is changed from 4’5″ to 4’8″, the player under 60 pounds should use a 29-inch bat. Baseball players weighing 61 pounds to 130 pounds are preferred to use the 30-inch bat.

Same height, but weight is 131 to 170 pounds, should use 31-inch bat sizes.

The last measurement for the players under 5′. The players with 4’9″ to 5′ height and weight distribution from 61 pounds to 90 pounds are the perfect match with a 30-inch bat.

But, the bat sizing will change to 31 inches, when the same lengthened players go over 90 pounds, up to 150 pounds.

Also, the same height with 151 to 180 pounds weights, should go for a 32-inch bat.

Let’s talk about the players more than 5′ long. Basically, the players who are between 5’1″ to 5’41, and weighing from 71 pounds to 120 pounds max, are recommended to use a bat length of 31 inches.

But, for the players that have exceeded their weight up to 160 pounds, a bat length of 32 inches is, preferable.

The bat length reaches 33 inches, while the same lengthened players have more weight than 120 pounds, and exceed 180 pounds of weight.

Let’s talk about the taller players. Players who are longer than 5’9″, up to 6′, need to be less confused about choosing baseball or softball bats. Weight up to 121 to 170 pounds are ok with the 33-inch bat.

For a heavier player, 34 inches bats could be picked. And at the last with the height of the players, the taller players who are more than 6′ long, should go for 34 inches baseball bats. They also should choose a heavier bat too.

Baseball Bat Size Chart: Pick the Right Bat by Your Age Group

Age Group 15-16 and Above: Finally, the adult group is here. At this age level, players normally play in collegiate baseball and above. So, the bat length must be increased to 32 to 34 inches or more.

Also, a heavier bat is just as well. You must use a bat with a bat drop weight of -3.

Based on the study result, we will just go to show you the mathematical calculation on how to choose the right bat weight for a player, based on the player’s height, and the average pitching speed he faces.

Let’s say, a baseball batter is 70 inches in length. And he faces a 70mph pitching speed on average.

Now, you have to multiply the height of the player by 30.7% of his height and multiply the speed by 12.15% of the speed. After getting the two primary results, add them to each other. the bat length will be shown.

In this case,

the height result= 70x.307= 21.49,

and the speed result= 70x.1215= 8.505.

Finally. the bat weight should be= 21.49+8.505= 29.995 ounces.

So, a player who is 70 inches in height, and faces on average a pitching of 70 mph should use a bat weighing 30 ounces.

But when the age ranges from 8 to 9, a bat length of 26 inches to 29 inches is preferable. For the age ranges from 10 years to 11 years, a softball bat ranges from 28 inches to 30 inches would be a perfect bat.

On the other hand, players aged between 12 to 13 years old should use bats lengthened from 29 inches to 33 inches.

But when your kids or you exceed the age range of 14, the bat length also should be reached 31 to 34 inches.

I call you for easiness, you will see a little difference in picking the size of a baseball bat and softball bat in length. 

What Are the Types of Baseball Bats & Materials?

Baseball bats are generally made of 4 types of materials. Wood, aluminum alloy, composite material, and hybrid (wood, alloy, composite, all could be used combinedly).

Wood Bats

Wood bats are made of pure hardwood which is only allowed bat in the Major League baseball-MLB. Ash, maple, hickory, and bamboo are used to make wooden bats. Among them maple gets is the most popular in making wooden bats over the last 20 years.

75 to 80% of MLB bats are made of maple wood by this time.

On the other hand, hickory wood is used less for its heavy weight. Ash is the second most popular wood bat. As the MLB only allows wooden bats, MLB players cannot use other materials bats.

However, a wooden baseball bat is ready for the game out of the box.

By the way, a wooden baseball bat gives the following advantages to a batter.

• A wooden baseball bat gives great balance.
• You can utilize your own muscle power instead of depending on the bat. No artificial or machine power.
• A wooden baseball bat gives better feedback to learn the exact sweet spot and hitting area.
• Helps to develop self-pitch discipline.

Aluminum Bats

Aside from the wooden bats, metal bats are used in the amateur leagues like little league baseball, high school, and collegiate baseball league. Among these, the metal bats must be batted ball coefficient of restitution in high school and collegiate baseball.

By the way, aluminum bats are made of high-grade aluminum alloy. They are hot out of the wrapper. That means you can use the bat out of the box instantly in the games.

Alloy bats tend is started back in the 1970s when the Worth company first brought them on the market. The aluminum bats are first introduced to college baseball in 1974.

The aluminum bats feature the following advantages in using them.

• An alloy bat is stronger and more durable than a wooden bat.
• Alloy bats are game-ready out of the box. No break-in time is required.
• Comparatively, aluminum bats are more cost-effective than wooden bats, since aluminum bats are more expensive. Because, wooden bats get cracked easily, whereas, alloy bats have a longer lifespan, and no need to replace often.
• Provide larger sweet spots.
• Most leagues allow aluminum bats. 

Composite Bats

Composite bats are made of materials that is opposing aluminum and wood. A material like carbon fiber is a reinforced polymer for making composite bats. Composite materials, on the other hand, give the ultimate advantage to doing the weight distributed properly across the bats.

Also, the baseball bat manufacturers get ultimate control over the bat gives them to ensure the required weight distribution, which could be balanced or end-loaded.

The composite bat has a significant feature. Manufacturers can ensure larger sweet spots for composite bats. As we discussed the aluminum bat before, composite bats give more durability than aluminum baseball bats.

But, on the other hand, bats are made of composite materials (reinforced polymer) that need a longer break-in period than aluminum bats.

By the way, composite bats are tensed to improve the trampoline effect over time. Though, the trampoline effect is governed by the NCAA, NFHS, and USSSA authorities.

However, don’t use composite bats under 60° F. This could be cracked if you do so.

Composite bats give a lot of advantages in their own way. Let’s see what will you get from the composite bats.

• Composite bats are designed in such a way that allows controlling the swing weight. Swing weight gives the feel of the heaviness of the bat while swinging. In the composite bats, swing weight distribution has more control than the aluminum bats.
• The trampoline effect is the phenomenon of when baseball comes out off the bat while contacting. This increases the exit velocity of the ball. The more trampoline effect, the harder hitting. Composite bats outperform all-aluminum bats in terms of the trampoline effect by keeping the value under the predetermined range.
• Composite bats are improved in the vibration sector. They ensure less vibration than wood and aluminum bats. 

Hybrid Bats

The name refers to the objective of the bat. Hybrid bats are made of a combination of different materials combined. Composite, aluminum, and wood, all could be used combined for making hybrid bats.

But, in most cases, alloy barrels and composite handles are combined hybrid bats. So, this ensures durability and lighter swing weight.

Hybrid bats feature some astonishing advantages in the long run.

• Hybrid bats are more cost-effective than composite bats but provide the feature of composite bats.
• Give lighter swing weight than aluminum bats.
• As the barrel of hybrid bats is mostly made of aluminum, they are ready to play out of the box.
• Also, hybrid bats are significantly durable.

But at the end of the day, all leagues do not allow hybrid bats to swing in them. 

Baseball Bat Facts

There are things to be clarified more before buying baseball bats. Bat length, drop weight, and swing weight is some important terms by the way.

Bat Length

Bat length is an easy term to understand. It is the determination of the whole length of a baseball bat. The length is measured in inches from its knob to the end.

A longer bat size helps you to reach more distance. As a result, you are able to hit the balls and even outside of the plate. But, longer bats do not mean the best option for always.

You should always measure the perfect bat length with efficient methods. A dedicated section you will find later on this post on how you can determine the perfect length for your bat choice.

By the way, most of the bat lengths range from 24 inches to 34 inches based on the age of the players. But, you will also see some 36 inches bats as well. 

Drop Weight

Now, let’s talk about one of the most used terms in baseball. I have mentioned the term drop weight a lot of times in this post already. So, what do understand about this term? Actually, how is it important so I needed to mention this at such a time?

Let’s find out the facts about the drop weight or bat drop.

Drop Weight is another name for the ratio of length to weight. The discrepancy between the bat’s length and weight is what causes the issue. Inches are used to measure length, whereas ounces are used to measure weight.

For example, is a bat lengthened 34 inches, and the drop weight is -5, which means, the weight of the bat is 29 inches. Oh! the drop weight is mentioned with a minus sign before the number.

The more the drop weight, the lighter the bat is. Less drop weight means heavier bats. So, a bat with a -3 drop weight must be heavier than a bat with a drop weight of -10.

Youth league baseball players basically use lighter baseball bats that could be weighted -5, -8, -10, -12, -13, and -13.5.

However, there are some precise entities that impact choosing the drop weight of the bat. They include the rules of the league, preferences of the players, and the governing body you are playing under.

Basically, all American baseball leagues are governed by the following three governing bodies: USA baseball, USSSA baseball, and BBCOR.

But, professional baseball leagues like MLB required a -3 drop weight. Also, high school baseball and collegiate baseball’s prerequisite is a -3 drop weight for baseball bats that are governed by BBCOR.

And, youth leagues are governed by USA Baseball and USSSA baseball which allows lighter bats with more drop weight than -3. 

Swing Weight

In the simplest state, the swing weight of the at refers to the power that it takes to swing the bat. That means you will feel the swing weight while swinging the bat.

Basically, a pivot point along with the mass moment of the inertia is considered to determine the swing weight of the baseball. Also, you can say, wing weight is the state of how particular the actual weight of the bat is distributed across the entire bat.

For example, you may have two bats that are 32/29. But you see, this bat will not feel the same even having the same total weight. As the weight distribution could be different for each other.

Here the term,s balance weight, and end-loaded come. For the balanced weight bat, you will feel the evenly balanced weight for the entire bat. On the other hand, the end-loaded bats have more weight implemented on the end of the bat.

The same weight, but distributed differently brings different swing weights for the same weight. 

How to Measure the Perfect Bat Length

There are things to consider out of the box too. You can skip the theoretical things when you have natural options to select.

Aside from picking the right bat size by age, there are ways that you can pick the right bat length naturally in your comfort zone.

By the way, bat length is important to give success on the plate. You shouldn’t pick the too long that would be rough to control by you. Also, you shouldn’t pick too short which will decrease your plate coverage.

Let’s check the way you can pick the right bat length as your own.

1. Simply take a baseball bat and position the knob side in the center of your chest if you’re at a baseball bat store. Propagate the bat’s end to your side now (Never bother with the left or right side, choose whatever you want).
   Now it’s a typical size for you if your fingertip fits comfortably at the end of the bat.
2. Place the bat’s knob on your chest. facing forward, stance. Spreading the bat now, attempt to go to the barrel’s middle. Take the shot if you can steadily grasp the bat’s barrel.
3. The last but not least, the option is to measure the standing size of the bat. Just keep the bat on the ground with its end. Put your hand straightly on the knob and grab it. See, can you comfortably reach the knob? Does the knob reach your palm?
   If so, you can take the bat.

Baseball Bats Governing Body and Rules

BBCOR Bats

BBCOR is the standard for governing adult baseball: high school and collegiate baseball. BBCOR set the rules for bats that are mandatory to meet the standard for high school and college baseball.

The BBCOR stands for Batted Ball Coefficient of Restitution. National Collegiate Athletic Association (NCAA) and the National Federation of State High School Associations (NFHS) are two governing bodies that control the BBCOR rules and regulations.

By the way, the main perspective of BBCOR regulation is to bring the metal bat’s performance near to wood bats. And this happens to keep lowering the trampoline effect under 0.50.

If you look for BBCOR bats, the bat must have a BBCOR .50 stamp on it. Otherwise, the bat will not meet the standard. Also, the drop weight of the BBCOR bats is -3. It is a must, not more, not less.

And, the barrel size diameter of the BBCOR bat cannot exceed 2 5/8 inches.

So, if you sum up the rules, they will look as follows.

• Drop weight is -3.
• The barrel diameter of the BBCOR bat must stay under 2 5/8 inches.
• The trampoline effect must be under .50.
• The max length of a BBCOR bat could be 36 inches.

USA Baseball Bats

USA baseball governs the little league baseball in America. The rules and regulations of the USA baseball bat are almost identical to the BBCOR rules.

But, there is a core difference between this two. The difference is their dropped weight. Where BBCOR is fixed with the bat drop weight of -3, the USA bats have broad acceptability here.

There is no restriction on the drop weight of the bat by the USA regulatory authority. As the little leagues are governed by the USA, and the players all are underaged, the bat weight should be lighter here.

And you know, the more the drop weight, the lighter the bat is.

The lightweight bats give youth players the to swing their bats fast. That helps to develop their ability to hit, and hitting style.

By January 1, 2018, USABats adopt new standards, which made all older bats before 2018 illegal. If you want to join the USA leagues like Dixie youth baseball, Cal Ripken, Babe Ruth, etc., you must use USA standard bats, or at least BBCOR certified bats.

USSSA Bats

USSSA stands for the United States Specialty Sports Association. It is a non-profit sports organization that governs different types of sports in the USSA.

In baseball, USSSA bats are used in youth leagues between the age of 5 to 14. There is ample reliability in the USSSA bats rules. Unlike BBCOR regulations, USSSA allows more trampoline effects which are up to 1.15 BPF (Bat Performance Factor).

So, if you look for a new bat for youth leagues with more trampoline effect and larger barrel size, USSSA bats are for you.

By the way, USSSA bats are made by only USSSA-approved baseball manufacturer companies like Wilson Baseball Equipment Manufacturer, Rawlings Sports Goods Company, Easton Goods Company, Marucci Sports Company, etc.

The USSSA bats must meet the following standards.

• BPF up to 1.15.
• Barrel size is up to 2 3/4 inches.
• The minimum bat length is 29 inches.
• Allowed drop weights are -5, -8, and -10.

How to Choose the Best Quality Bat for You?

After a long journey, now we may know what is the perfect size bat for a baseball player. I don’t think that you will be confused further after entirely adopting the chat we have provided based on several types of surveys and studies.

But, it’s important to pick the best baseball bats when it comes to quality. Quality and sizing are not the same facts. So, if you pick a poor bat with the right size, it will not serve you a lot.

Just make sure you combine the right size along with the best quality with your determined budget.

So, how come you be assured of the quality of a great bat? Let’s find out the ways.

Materials and Durability

The most essential fact to consider is the materials of the baseball bats. Materials are catalyzers for keeping the bats durable. Also, the materials determine the price of the bats as well.

There are mainly two types of materials used for making baseball bats: wood and metal.

Wood bats are less-prices. Different woods, such as maple, ash, or birch are used for bat making. Wood bats are fundamentally BBCOR approved along with -3 drop weight.

Aside from the wood bats, alloy and composite materials are used to make metal bats. Metal bats are costlier than wood bats.

On the other hand, alloy bats are hot out of the wrapper. This means alloy bats don’t need break-in time. Though composite bats need a particular break-in time, they are more durable than alloy bats.

One-Piece Bats and Two-Piece Bats

It is another important point to consider that either a one-piece bat or a two-piece bat will take. There is a fundamental difference between the one-piece bats and the two-piece bats. This is the flex and energy transfer fact.

Basically, wood bats are one-piece. One-piece means the continuous made of the bat without any joints. One-piece bats are stiffer, generating more power.

On the other hand, two-piece bats mean two separate pieces of bats joined together. They are made with the fusion of a separate handle and barrel. As a result, the two-piece bats give more flex and faster bat speed.

Also, the two-piece bats are designed to reduce vibration and stings. It’s upon you which one suits you most. If you are a power hitter, one-piece could be your choice. But, if you are got to go with two-piece bats with more flex. 

Frequently Asked Questions

Is bat Rolling Illegal?

Fundamentally, bat rolling is not illegal. But, if it changes the shape and performance of the bats, it’s no more legal to use bats. So, make sure, your bat rolling machine doesn’t violate the rules and changes the shape of the bats.

Wrapping up

A proper bat size chart is likely to help you to pick the right-sized bat for swing. Before picking the bat for the next little league baseball league or adult baseball, it’s essential to do a precise study.

Aside from the theoretical studies, a physical try will be more effective to pick the right-sized bat fast. But, be sure, a precise theoretical study will help you to determine the range of the bat size, and give you more options.
