Rip said it right, its a little more than just enough. I consider the standard and delux both 3 season tarps so I went with the smaller one. I've never sat out any real bad storms with it, but plenty of people have. I will say wind blown rain could be an issue through its steep cat cut from the ridge line to the edge. The 7' widrh is perfect for me but you really have to pitch it right in that situation.
The standard works fine more me excluding winter and those tough spring storms but I feel the delux might be the same but give you just a tad bit more room for cooking and such. Anyone else feel free to chime in please.
