    I have refereed in a few states and I have never heard of a junior high grade using a 28.5" ball. There is a good chance you will have a 6'0"ish height player on a good 7th grade team. That would be ridiculous using a kids ball. Also the question is bad. This is because NFHS and high school rules in general are not subject to non-high school basketball. The specific league you play in notes that it will choose to play by a standard and could even say it plays by NFHS but wants a certain size ball used. The league can do whatever it wants - there is no body for 7th grade bball. – Coach-D Oct 11 at 18:02
  • Question is not bad as most middle school teams follow the HS rules with a few exceptions. As they do in states that surround me. – Clarence Klopfstein Oct 11 at 22:06

Ebay listing says the 28.5" Spalding-1000 is the official size for women and boys 12 and under.

Although I'm having trouble finding records for many states, so far I've found:

Alabama & Alaska use NFHS rules, but don't specify ball size for Junior High. Probably 29.5".

29.5 Arizona

    This is not accurate at all. I've been doing my research. So far, every state I've gotten info from is 29.5 except Ohio. Updating post momentarily. – Clarence Klopfstein Jun 12 at 21:36
  • There is nothing that governs 7th/8th grade basketball in the US. Each league can do whatever it wants (I am sure 99% use 29.5" at these ages as this size ball is usually introduced in 4th-5th grade) – Coach-D Oct 11 at 18:04
