Usually if you look at the manual either physically or online it will tell you. Or better yet you can look on the sides of the motherboard, it's in little white letters if memory serves me right.

remove the cover off the case and look at the mother board if it has white card slots for pci cards then it's a ATX case, look on the motherboard around the edge and it will say atx on it as well.
