Players falling in a similar height range but weighing about 91 to 120 pounds can go with a 29 inches long bat.

Players with a height of around 3’9″ to 4″ and weighing a maximum of 60 pounds can opt for 28 inches bat. The same bat may ideally work for players weight 61 to 80 pounds. Players of the same height but weighing in the range of 91 to 10 pounds can opt for a 29 inches long bat. Players weighing more than 120 pounds or more can go for a 30 inches long bat.

As per league

Different leagues demand bats with distinguished certifications as per the age. Little league baseball players are recommended to have a certification from USA Baseball. These bats are approved beforehand by several youth baseball leagues, such as; Little League Baseball, Dixie Boys Baseball, Dixie Youth Baseball, Cal Ripken League, Babe Ruth, etc.

Bats from the United States Specialty Sports Association (USAA) work great for 14 years old players or younger. For adult players, it is believed that Batted Ball Coefficient of Restitution (BBCOR), has set the standards. All high school and college players are mandated to use a BBCOR-certified bat.

Baseball bat material

  • 1. Composite: Bats made of composite materials are very much similar to those made using carbon fiber. Composite bats allow manufacturers to produce bats with excellent control over weight distribution across the entire bat. Being loaded at the end, they hold more weight than others.
    • Composite bats are prone to break after hitting 100 to 150 ball strikes. Avoid using composite bats in cold weather, as the temperature drop may sometimes lead to cracking these bats.
  • 2. Hybrid: Alloy and composite are a combination of hybrid bats. The barrel is an alloy made with a composite handle. They together form the best combo to make an elite bat. 
  • 3. Wooden: Wooden bats may not deliver power and durability unlike alloy bats, but the appearance is pleasing. They help prep the players to play in the big leagues, where it’s mandatory to use wooden bats.

Wooden bats are made with ashwood, birch, or maple. There are different sets of rules as per the league.
