I have a little quilt size chart - it says a queen comforter is 88x94 and a bedspread is 102x113. I tend toward the smaller ones, as I prefer having a dust ruffle and shorter (that floor length) quilt. I would probably add a border onto one that 80x85, just for a little more room, but it's not necessary. 80x85 should, by all means, be big enough.
