So sorry I never saw your message until now but without getting it out I’m not sure the size. It’s was the medium size ground sheet from go outdoors. There was small, medium and large but these are not ones that are made for this tent
Hi, both sidewall doors zip all around and the main front interior door opens just over half way. The main porch opens all the way and you can either take it off or use it with king poles to make a shelter porch. Hope this helps!
