Okay, I found and fixed the problem. I added the style of the infobox which specified its size:

{| class="infobox" style=" width:250px ; ; -moz-border-radius:10px; -webkit-border-radius:10px; -o-border-radius:10px"

I added this to the actual template so the problem should be fixed. You can alter the size in the section I've bolded. :)
