What size are the Tent Pads? Trying to figure out if a 10 or 12 person tent will fit?

I would say the spot we had was 10'x15'. Probably could fit an 8 person tent at the most

They are only about 6×10, but in some of the more open sites you may be able to fit a large tent. Some of the more secluded spots would make it hard to put such a large tent.
