They run very small. My king size pillow won't go all the way in there they are only a little larger than regular pillow cases. The stitching is all messed up on the sheets and they run small too..I had to pull and pull and they don't cover the mattress very well. I've always bought cheaper sheets and had no problem at all so this was very disappointing that for once I got more expensive sheets and they are the worst I've ever had.
