So I was sitting around thinking about this and that and suddenly I wondered just which hold in skyrim is the biggest or if they are all roughly the same. Not sure why it matters or even why I care, it's just suddenly a question I want the answer to. I checked UESP a bit and couldn't find an immediate answer so I figured I would simply ask, and see if anyone knew.

Try to keep it civil please and thanks for any input in advance.
