Below is a rough guide for bat selection. It is simply a place to start and depends not only on the size of the player but the level of competition (better pitching may require a lighter bat). It is better to err on the light side rather than the heavy side. Today’s power hitters in the major leagues use lighter bats than power hitters of yesterday.

Our current rules indicate that the maximum length for our bats is 36 inches, without defining the length to weight ratio until the 14U - 18U divisions, where this ratio is shown on the bat as a negative value, or -3 ounces.

Age	Weight Minimum	Weight Maximum	Length Minimum	Length Maximum	Barrel Size
6-7	17 Ounces	19 Ounces	24 Inches	28 Inches	2 ¼
8	19 Ounces	21 Ounces	27 Inches	30 Inches	2 ¼
9	20 Ounces	23 Ounces	28 Inches	30 Inches	2 ¼ to 2 ¾
10	20 Ounces	23 Ounces	28 Inches	31 Inches	2 ¼ to 2 ¾
11	21 Ounces	24 Ounces	29 Inches	31 Inches	2 ¼ to 2 ¾
12	23 Ounces	25 Ounces	30 Inches	33 Inches	2 ¼ to 2 ¾
13-14	23 Ounces	28 Ounces	30 Inches	33 Inches	2 ¼ to 2 ¾
15 +	24 Ounces	30 Ounces	30 Inches	34 Inches	2 ¾

Bottom Line: The lighter, longer and larger the barrel size equates to a faster swing, longer reach and more surface area with which to make contact with the ball, or very simply, "more hits"!
