Bat length is mostly driven by height, and drop weight mostly by age and strength. As a rough starting point, a player around 4’4”–4’7” typically swings a 27–28” bat, while a player around 5’4”–5’7” is usually in a 30–31” bat. Leagues set rules by age and skill level so the game stays safe and fair.

Frequently asked questions
Why are there different bat sizes and weights?
Leagues set rules based on age and skill level to keep the game safe and fair. Younger or smaller players use a lighter bat since they have not built up bat speed yet. As players get older, faster, and stronger, leagues tighten the rules, such as a smaller allowed barrel, a heavier minimum bat, or a different certification, so the ball does not come off the bat too fast for the level of play.
What size bat does my child need?
Bat length is mostly driven by height, and drop weight mostly by age and strength. A player around 4 foot 4 to 4 foot 7 typically swings a 27 to 28 inch bat, while a player around 5 foot 4 to 5 foot 7 is usually in a 30 to 31 inch bat.
Can I use a USSSA bat in Little League?
No. Little League Baseball Minor and Major divisions require the USA Baseball USABat stamp. Little League's Intermediate and Junior divisions allow either USA or BBCOR bats, and Senior League requires BBCOR only.
Do I need a BBCOR bat for high school?
Yes, NFHS high school and NCAA college baseball both require a BBCOR-stamped bat at exactly a -3 drop. Wood bats are also always legal at this level.
