How Wide Is a Baseball?

how wide is a baseball

A regulation baseball is about three inches wide.

More specifically, baseballs have a circumference of between 9 and 9.25 inches, owing to the fact that they can change shape and size slightly due to a variety of factors, including atmospheric conditions, manufacturing variances, and the age of the ball.

That circumference translates to a diameter (width) of roughly between 2.8 and 3 inches.
