2. What basketball size do i need?
Basketballs also come in a variety of sizes depending on the age and gender of the player, so it’s important to get the right size according to your needs.
Playing with an incorrectly sized ball can have long-term negative effects on a player’s technique.
When younger players use a larger basketball, they will usually compensate for the incorrect weight by shooting with both arms or dropping their shoulders, thus developing a bad shooting form and getting in the way of good technique.
Additionally, different leagues have various restrictions regarding size, material, and colour for game balls that they permit.
