Size 7 (29.5" circumference) is the only legal size for high school boys' basketball in the US, per NFHS rules. This is also the standard for college (NCAA) and professional (NBA) basketball.
The NFHS has always used Size 7 for boys' high school basketball. There was no recent change—this has been the standard for decades. The confusion sometimes arises because:
For US high school boys, it's always been Size 7.
No. All high school boys—freshmen, JV, and varsity—must use Size 7 (29.5") in official games and practices where NFHS rules apply.
Exception: Some middle schools (grades 6-8) may use Size 6, but once players enter high school (grade 9), they must switch to Size 7.
Look for these 4 signs:
All Hebei Starry Size 7 basketballs have the NFHS approval mark and come with a certificate of compliance.
