Current IESA Baseball Bat Standards

BATS (NFHS Rule 1-3-2)

Any non-wood bat that has a barrel diameter greater than 2 5/8 inches is illegal.

All non-wood bats 31 inches and over in length must meet all of the NFHS standards as detailed in NFHS rule 1-3-2 including: a maximum barrel diameter of 2 5/8 inches; maximum length of 36 inches, a Batted Ball Coefficient of Restitution (BBCOR) silkscreen label on the bat; and in weight, the bat shall not weigh, numerically, more than three ounces less than the length of the bat (e.g., a 31-inch-long bat cannot be less than 28 ounces).

Additionally, any bat that has a BBCOR label that meets the NFHS standard is a legal bat.

Non-wood bats 30 inches and under in length which have a greater than three ounce weight vs. length differential may be used provided the barrel diameter does not exceed 2 1/4 inches (e.g., a 29-inch-long bat may weigh 20 ounces and is legal provided the barrel diameter does not exceed 2 1/4 inches). The BBCOR label is not required on this type of bat.

Wood bats that are manufactured in accordance with National Federation rules may be used.
