Yes, I had to click on a few things to come up with the floor dimensions, but it was there (this is slightly reminiscent of when I tell my boyfriend that such-and-such is on the bottom shelf of the refrigerator and he can't find it because there's a jar in front of it...)
But I will say that whoever is in charge of the info that goes on the GoLite site could do much better. I had to email them about the Chrome Dome umbrella to ask about UPF rating, since their regular umbrella showed as 50 UPF but Chrome Dome showed nothing. It turned out that they had the ratings on the wrong item! The person who handled my inquiry thanked me for pointing out the problem, and said they'd fix it. They still haven't, and this was months ago.
Since Campmor had specs for the floor, why don't you search their site for the height on the tents?
