# Softball Performance – What is the Diameter of a Softball?

*By Coach Marc*

What is the diameter of a softball? That’s funny because that’s twice this month that we receive emails from young softball players asking this question.

You see, we have many young softball players on our newsletter mailing list (you should subscribe if you’re not – it’s free!) and many of these young ladies decide to do school papers on topics related to softball and are looking for facts about the game online.

So what is the diameter of a softball? As you know there are two different sizes for softballs:

1) The small ball – which a circumference of 11 inches and a diameter of 3.5 inches. This ball is used in youth softball – usually 10 and under.

2) The big ball – which has a circumference of 12 inches and a diameter of 3.8 inches. This regular size softball used by all other players.

If the formula for circumference is C=2piR , and C=12 then the formula would read 12=2piR. Then, if we divide both sides by 2pi, we get that R=6/pi which would be 1.9098593171.

That’s because people in Chicago can’t hit a regular sized ball
