Is it possible to give the pigs too much space? Or is that not really such an issue?

A lot of different sites say different things and I wanted to make sure I get this right! I have one piggy right now and I might get another (Pumpkin is from a pet store, but I learned how it's better to get them from shelters!) and I was wondering would this be a good size cage for 1-2 cavys?
