Ball Size Guide

There are five sizes of basketball, size 7, size 6, size 5, size 4 and size 3. Read on to discover these in more detail:

  • Size 7 – This is the NBA standard ball size for men’s professional basketball. Measuring 29.5 inches in circumference and a standard weight of 22oz.

  • Size 4 – Ideal for children under six; the smaller size and weight is perfect for those with smaller grips. Measuring 25.5 inches in circumference with a weight of 14oz.
  • Size 3 – The smallest of the group but by no means any less important, this ball is perfect for children aged 4 and under with a circumference of 22.5 inches and a weight of 10oz.

Did You Know?

It’s believed that the size 6 ball was introduced to give women’s basketball a new edge. The smaller and lighter ball is due to the fact that female players often shoot further away from the net with greater accuracy.
