The Best Bat for 9 Year Old (9U)

When choosing a bat for a nine-year-old, there are many qualities to consider before deciding on a brand or model. Some of them include materials, durability, and weight. Some stand out in the crowd. Several things differ between adults and children playing sports. 

What aspects do you need to look for when choosing bats?

The height and size of the equipment used are among them. At times the level of care needed for the equipment and the rules are factors. These differences apply to the selection of bats for nine-year-olds to use for tee-ball, softball, and baseball. 


As players become older, the difference in skill levels widens. Swinging speed for nine-year-olds varies from 20 mph to 45 mph. Some kids at this age are small beginners who lack athleticism, while others are big kids with above-average hitting mechanics.

Weight and size are of importance at this age. A 27-inch bat, weighing 14 ounces, is about the smallest bat a nine-year-old will use. Bats weighing 21 ounces and 31 inches in length are the largest.The wide range is due to heights that vary from 48 to 62 inches. An average-sized bat for this age group is 29 inches long and weighs 17 ounces. 


Understanding the trampoline effect has an impact on the choice of bats. The trampoline effect is the bounce-back of a baseball from an aluminum bat or a club. The thinner the wall of an aluminum bat, the more quickly it cracks, dents, and becomes unusable.

Better materials are needed to create thinner walls that are as flexible as aluminum, but stronger. They include a superior metal such as titanium, a stronger aluminum alloy, or composite material. 

For nine-year-olds, bats are either composite or aluminum alloy material. In two-piece construction, the barrel and handle are of different materials. One-piece construction has only one material. It is usually an aluminum alloy. Composite materials are typically made of carbon and graphite bonded with resin. They also have a higher ratio of strength to weight and a higher trampoline effect.


The feel of the bat may determine the best weight of the bat for a nine-year-old. Let the child take a few swings to assess how heavy it is. The drop of the bat needs to be taken into consideration. 

Drop weight is the difference between the weight and length of the bat. The drop weight and swing weight are not to be confused. As the drop weight increases, the bat becomes lighter.

Most companies specify the drop weight of the bat. A child’s weight impacts the appropriate weight of the bat. Children weighing approximately 54 to 60 pounds need a bat that weighs between 17½ to 19 ounces.

A long, light bat can be swung very fast. There will be little inertia behind it. A short, heavy bat does not have the fastest swing speed but has plenty of inertia. The aim is to create a balance between weight and length.

BPF in your league

BPF is the Bat Performance Factor. It refers to the increase of liveliness when a ball hits a bat compared to throwing it against a solid wall. A BPF of 1.20 means the rebound is 20 percent faster when hit with the bat.

Little League standards and specifications are the same as that of softball bats. They are to be smooth, rounded sticks made of wood or materials tested and deemed acceptable to the standards of the Little League.

Bats are not to be more than 33 inches in length and not more than 2¼ inches in diameter. Wood bats are not to be less than 15/16 inches in diameter. Non-wood bats require labeling of a BPF of 1.15.

Common Questions Before You Buy

  • How much should you spend?

The highest-priced bats have more performance features and the best design. However, all players do not need some of those bells and whistles. There is no guarantee that a child in their first or second year of youth ball will stick with the sport.

Parents of new players should not invest in the hottest bat on the market. Kids also grow out of bats. Mid-priced bats have decent features. Avoid the low-end priced bats. They do not perform, as well.

  • What would be the appropriate size to purchase for a nine-year-old?

There are helpful charts available to help determine the appropriate size. The best way to choose is to find a comfortable bat. Two tests to use, include holding the bat of your choice. If the palm reaches the handle with the bat at your side, it is the right size. You should also be able to reach the barrel when the bat is placed at the center of the chest.

  • Are most bat USA certified? Is there a warranty on all these bats?

Bats are tested for their performance to be certified. Those certified, are stamped as USA-Bats. They conform to standards and can be used for league play. Not all bats have a warranty. Those that do are limited warranties that apply to one bat when originally purchased. They are replaced or repairs one time under warranty.
