How big is an Olympic standard shot put ball?

An Olympic shot put weighs 7.26 kilograms for men and 4 kilograms for women. The men's shot put is 110 to 130 millimeters in diameter. The women's shot put is 95 to 110 millimeters.

In the Olympics, 12 female competitors and 12 male competitors qualify to compete in the finals. The finalists for each gender get three shots each to determine who makes it into the top eight.
