Size 4 (25.5-26.4” circumference) is the official recommendation for ages 9-11. This size balances control and skill development for pre-teen players. Hebei Starry’s SB-4Y model includes a softer composite cover to reduce hand fatigue during long practices.
Palm Test: If your child can palm the ball with fingers slightly spread (hand span ≥7.5”), they’re ready for Size 5 (ages 12+). Warning: Jumping to Size 5 too early can lead to poor shooting form—a habit hard to break later.

Coach Michael T. – Chicago Youth League
“We tried 3 brands before Hebei Starry. Their Size 5 balls have the best grip for our 12-year-olds—no more slipping during layups. Zero complaints after 6 months of heavy use. 5/5 stars.”
Principal Linda R. – Greenfield Elementary, TX
“Ordered 200 Size 4 balls for our PE program. The color customization was a hit with the kids, and the durability saved us $3,000 in replacements. Will reorder next year!”
David K. – Parent Association Rep, CA
“Parent complaints about ‘cheap balls’ dropped to zero after switching to Hebei Starry. The Size 3 for our 6-year-olds is perfect—light enough for little hands but still feels like a real basketball.”
James L. – AAU Tournament Director, FL
“We use Hebei Starry’s SB-5Y for all our youth tournaments. Consistent bounce and FIBA-compliant sizing mean no disputes over equipment. Highly recommend for competitive play.”
Sarah M. – PE Teacher, NY
“Finally, a Size 4 ball that doesn’t feel like a toy. The 8-panel design helps my students learn proper rotation on shots. Best purchase of the year!”
