Popular bat length for 18u

[BLB]

What bat length do most girls tend to use at the 18u age group?

 

[Ken Krause]

Most are probably around 32 or 33 inches. But it's a function of their height more than their age. Good rule of thumb is the knob of the bat should come to their wrist when they stand upright and hold it with the end of the bat on the ground.
