How do I know what length is right for my child?

How do I know what bat weight is right for my child?

When buying a bat for your player it is important to understand that Bigger isn't always better when it comes to bat size and weight. Although players like to swing bigger bats, that doesn't always translate into helping them be successful at the plate. Having a lighter bat, especially in the younger age divisions is very improtant. Kids aer still developing their hand eye coordination and having a bat that they can mange is critical. Kids with bats that are too heavy often develop improper swing mechanics due to the weight of the bat.
