Bat Sizing Guide | Baseball & Fastpitch Softball Bat Size Chart

We recommend starting with a length based on a player's height and weight as seen below. These charts simply serve as a starting point. As far as the best weight, it will vary from player to player depending on one's personal preference, age, hitting style, bat speed, and strength. Typically we recommend the longest and heaviest bat that you can swing without losing bat speed or affecting your swing. The FEEL of the bat will be the most important factor. You have to make sure it feels right to you. The more you like it the more confident you will be at the plate! 

HELP DECIDING BETWEEN TWO SIZES

  • Longer/Heavier Bat: Will be better for players that are growing but can cause a dip in their swing. Also it moves the sweetspot of the bat further away from the player which can cause more miss hits. For a growing or younger player that can handle the heavier bat without issue compared to the lighter, it is best to go with the longer/heavier bat.
  • Shorter/Lighter Bat: Will give far more control of the bat, and keep the sweetspot closer to the player. They can always adjust in batter's box. The down side for growing players is you might have to buy more bats over time. Tony Gwynn, one of the greatest batters in MLB history and a grown man who weighed well over 200lbs, used a 32 ½ inch bat the majority of his career. It is not always better to just keep sizing up.

IMPORTANT BASEBALL BAT RULES

Baseball unlike Fastpitch Softball has certain Drop (Length-to-Weight Ratio) requirements per age group. It is important to keep track of these as there is a certain point over 4 years where you have to have a different drop each year. If you can swing the heavier earlier without hurting your swing it can be beneficial.

  • 12 & Under (12u): Any Drop
  • 13 & Under (13u): Must be a DROP 8 or Heavier
  • 14 & Under (14u): Must be a DROP 5 or Heavier
    • NEW for 2026: USSSA and Perfect Game have opted for 14u to swing BBCOR (Drop 3) bats. Some states can opt to allow Drop 5's so check with your tournament directors to see what you can swing. 
  • 15 & Under (15u): Must be a BBCOR (Drop 3)
  • High School (Regardless of Age): Must be a BBCOR (Drop 3)

LENGTH-to-WEIGHT RATIO

The ''DROP'' as some may call it, or the number with the MINUS in front of it is the LENGTH-to-WEIGHT ratio. This defines the difference between the length of the bat in inches and the weight of the bat in ounces. The larger the number, the lighter the bat.
