When to switch from 28.5 to 29.5 basketball?

The switch from a 28.5-inch Basketball to a 29.5-inch basketball typically occurs when players reach high school age, around 14 years old, or when they are physically ready to handle the larger size. This transition is often guided by the player's skill level, strength, and the level of competition they are participating in. Coaches and leagues may also set specific age or gender guidelines for when to make the switch. It's important for players to feel comfortable and confident with the basketball size they are using to optimize their performance.
