There is no specific weight for a wooden bat. Professional batters have used bats ranging from 30 to well over 50 ounces. Babe Ruth used 40 to 54 ounce bats. Ty Cobb and Joe DiMaggio used 42 ounce bats. Mark McGwire used a 35 ounce bat. So with all that in mind, it all just depends on what kind of bat fits you better.
