Basketball Sizes by Grade and Gender

MYBA encourages every player to bring a basketball to practices.  It’s important for player development to practice with an age-appropriate ball.  Please refer to the size guidelines below when selecting a basketball for your child.  Coaches will be provided with a few spare balls for practices in the event your child forgets their ball or does not own one.

  • Girls and Boys - Size 27.5
