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.
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.
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.
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
