Internal dimensions that are listed are not even close.  If you are trying to fit this around something, then be aware that it is much smaller than advertised.  We were trying to fit it around a hot tub, and the listed dimensions were going to barely work.  However, it did not end up fitting.  After assembling, I measured it myself.  This list the internal dimensions as 8'2 13/16" by 7'11 9/32", ignoring the hight.  The TRUE internal dimensions are 7'7" by 7'1".  That means that they were off by 7" in one direction and more than 10" in the other direction.  This did not end up fitting around out hot tub.  We moved it to our outdoor dining set, and it doesn't even cover that.  Our set seats 6 and one person on the end sits outside the canopy.  It looks nice, but it is a very different size than listed.  Unfortunately, return reasons say that it needs to be unopened and unassembled.  It would have never been bought if the dimensions had been listed correctly.  I am very disappointed.
