IMHO, you're cutting it too close for comfort. I imagine people sitting at the table would like to be able to scoot the chairs out and you're only leaving yourself 24" from table edge to patio edge. Don't you want people to be able to walk around behind the chairs? If you could manage it why not go with an 8'x8'?

Thanks for the reply.
The smaller the better, as my backyard is pretty tiny. I shoulda gotten a smaller table, but it was a good deal so I went with it. The deck will only be about 6" higher than the rest of the yard/garden, so walking around space is not really needed. But of course, I'd like guests to be able to sit comfortably (without falling off the edge lol)
- Maybe 7x7?
Sry, I don't have a pic of the area in question - my yard is so tiny, I couldn't get a good photo of it.
