The quilt is a king folded in half.. I bought a double / full duvet. Perhaps a single would have been a better fit. The quilt inside dosn't even reach the edges of the duvet when attached on 1 side. It is in fact sewed about every 8-10" into the duvet at this point praying it would help it stay put but I don't see it helping much. The width of the duvet is about 4 inches wider then the quilt when doubled.
