How much does a softball weigh?

A regulation 12-inch softball weighs between 6.25 and 7 ounces (177–198 grams). A 12-inch ball is the standard size used in slo-pitch and fastpitch.

There are also 11-inch softballs, which weigh only slightly less. These 11-inch balls are often used in youth leagues, ladies games, and co-ed divisions.
