Is an softball similar to the size of an coffee mug?

A softball is similar to the SIZE of a coffee mug, but not the SHAPE. I hope this helped. 

It really depends on the size of the coffee mug but with an an average sized mug, but for starters, the softball isn't the same size, second, the softball would probably be wider but still a little bit shorter than the coffee mug

I hope I helped

Please leave thanks:)
