- Sizing Guide
Bat Size Guide-Help Selecting Baseball and Fastpitch Bat Size
Selecting The Appropriate Bat Weight
- The bat size that best fits you will be one that is comfortable, easy to swing and allows you to produce the greatest bat speed and power.
- To obtain your optimum bat select a bat that is not too long/heavy or too short/light.
- A bat too short won't provide maximum power or barrel length, while a bat too long will be too difficult to handle and will also slow bat speed reducing power.
- First begin with selecting a length. If possible use the previous bat you swung to help establish a length. For example if you used a 30 in bat and now feel that you are ready to move on to a larger bat a 31 in could be the next step.
- You can also use the chart below for the average bat lengths based on your height, weight and age.
- The chart below is just a guide as each player's strength and bat speed differ.
- While the chart below was primariy designed for baseball, we have found it works fairly well for fastpitch bat sizing too. For fasptitch, however, refer to only the player height and discregard the player weight. Also, see notes at the bottom for additional notes on fastpitch bat sizing.
- Need help selecting the proper bat size? Give us a call @ 888-854-2287.

Selecting The Appropriate Bat Weight
- The bat weight is equally as important as the length in selecting the optimum bat size.
- Bat weight differs greatly depending on the age range and is usually referred to as the "drop" when associated with the length and weight.
- The drop is the difference between the length of the bat and the weight of the bat. For example if a bat is 30 in. long and weighs 20 oz. then the drop is 10. The larger the drop, the lighter the bat.
- The average bat drop can best be broken down by age range.
- Average - drop 12
- Power Hitter - drop 10
- For ages 12 and under, drop 10 is the average
- Over age 12 range from -10oz to -5oz depending on the players strength and bat speed.
- *Check with your local league or organization to find out if there are any restrictions on barrel diameter or bat weight.
- All high school or college bats are drop 3
- Freshmen/Sophmore High School players: 31 and 32 ich are the most popular
- Junior/Senior in High School players: 32 and 33 inch are the most popular
- College Players: 33 is the most popular size.
- Age 13 and under, average drop - 11oz or 12oz.
- Age 14 to 16, drop 10
- Age 16 and up, Drop 8oz to 10oz. Drop 10 is still the most popular drop, but some power hitters prefer a drop 9.
