minus 3
There is no legal requirement, although the strength of a player of that age could handle a drop 5 bat. Its not until the high school level that players are required to use a drop 3 bat. So to get players use to a bat that size, a 7th grader or 8th grader should use a drop 5 baseball bat.
A thirty inch bat that weighs 20 ounces would be a minus 10
I doubt there is a rule requiring a specific drop. Most players at that age would be using -10 or -12.

Junior's bat are of Size H. Means under aged players can use this size of Bat
(Unless you are a unborn baby) No bat is the size of a human.
That is called the 'drop'. Subtract the length of the bat in inches from the weight of the bat in ounces and you get the drop, or minus number. EXAMPLE: A 34 inch long bat weighs 30 ounces. 30-34=-4. -4 is the drop of the bat.
I think you mean baseball bat. In the younger leagues you can get a bat that is a drop 10. In the older leagues, it is usually a drop 3.
A -3 Bat is a bat where the weight is equal to the height minus 3 So if you had a 34 inch bat, the weight would be 31 oz.
I can be -3 to -9
