Bat weight is measured in ounces (oz.). A bat’s weight is often tied to its “weight drop” -- its length in inches versus its weight in ounces. For instance, a 32-inch, 22-ounce bat would be referred to as a -10 bat.
bat length (in.) – bat weight (oz.) = weight drop
As a general rule of thumb, the higher the competition or league level (meaning, from youth league up to the pros) the lesser the weight drop. A lesser weight drop means the bat feels heavier. So a -5 bat will feel heavier than a -10 bat.
Selecting the right bat weight depends on three main factors: sport, league rules, and player preference.
Leagues have rules identifying which weight drops are permitted for play. Prior to choosing a bat, we recommend finding out if your league has a specific standard for bat weight drops in order for them to be permitted. For more information on league rules, please refer to the Your League section.
Players with less experience generally swing lighter bats in order to have better bat control. More experienced players generally swing a heavier bats to help maximize power. A way to tell if a bat is right for you is your swing speed. A bat that is too heavy is harder to swing, causing a loss in momentum, reduced distance or a miss altogether. If a bat is too light for a player, the player could miss out on the extra force they could generate from a heavier bat. A happy medium needs to be found. It is highly recommended you demo a bat against live pitching speeds in order to find the best weight for you.
Since slowpitch bats have a set length of 34 inches, they are not often referred to by weight drop and recommended weight is a matter of preference. Most slowpitch bats weigh between 26 and 30 ounces.
*This is for example purposes only. The best way to find the right size bat for you is to demo them, preferably against live pitch speeds.
**Manufacturing tolerances, performance considerations and grip weight may cause variations from the listed weight.
