Baseball Bat Sizing Guide: What Size Bat by Age & Height
Baseball Bat Sizing Guide: What Size Bat by Age & Height
To size a bat, match the length to the player’s height and weight, and the weight drop to their age and strength. Quick check: stand the bat next to the player’s leg — the knob should reach the middle of the palm when the arm hangs down. Use the chart below as a starting point, then swing a few at our McDonough store.
Bat length by age (general guide)

| 5–7 | 24–26 in. |
| 8–9 | 26–28 in. |
| 10 | 28–29 in. |
| 11–12 | 30–31 in. |
| 13 | 31–32 in. |

Understanding “drop” (length-to-weight)
Drop is the bat’s length in inches minus its weight in ounces. A bigger drop (like −10) is lighter and easier to swing; a smaller drop (−5 or −3) is heavier. Younger players use −10 to −8; high school BBCOR is always −3.
