I don't find the published sizes very helpful at all. Usually they are longer than wide and I don't tuck them under the pillows and have a footboard so I want them wider (to drop down the sides) rather than longer. Since the quilt is for you, measure how wide and long the bed is, then add a foot or so to the length and a couple of feet to the width for body coverage when you are under it. If that is enough for overhang then you are good since you won't be under the quilt when it needs to hang over the sides or bottom. Don't worry about what length other people say - just use what is bet for your bed and style of living
