We have a narrow width patio, exactly 10ft from wall to edge of the concrete pad and 18ft long.  Since this is labeled as 9.5ft wide, I was able to narrow my search to find this and I’m so glad I did. It fits our space perfectly!! 
Dimensions are from tip to tip of the overhanging edges. 
Pretty easy to put together- it’s better when you have a few sets of hands and a couple ladders.  Just be sure to read each step carefully- we managed to skip inserting the rollers and attaching the clips for the bar.  Thankfully it was pretty easy to quickly do both wout taking anything apart. 
All in all a fantastic addition to upgrading our patio space.
