9-foot umbrella for 48 table. Good sun protection, but it doesnt really protect against rain. I think an 11-foot diameter might be a little too much for my deck, and I dont know how more rain protection it would provide anyway. Tough to tilt and untilt, so Ill get auto tilt next time. Didnt think it would be a big deal, but I had to get a step ladder to get the right leverage. Seems fine overall, though.
