This size is specifically designed to accommodate the hand size and strength levels typically found in female athletes and younger players.

The 28.5 inch basketball is predominantly used in women’s professional leagues, collegiate competitions, and high school games for both boys and girls in certain age groups. The reduced size allows for better control, quicker ball handling, and more accurate shooting for players who might struggle with the larger men’s size.

  • Leather: Used primarily in professional indoor play for superior control and feel but requires break-in time.

Players should consider the surface they play on and their level of experience when selecting the ball material. Proper inflation and maintenance also ensure the basketball maintains its shape and performance over time.
