Well as far as I know at this time the pillow is the right size. I have a cover arriving soon in Sept that I needed size 16” x 26”. Little bigger than I was thinking but that is the correct size. Will update when I receive the cover. I received the cover but after a day of this pillow enclosed within the cover a really weird smell was coming from the pillow. I removed it from the cover and I am airing it out. It’s getting there slowly.
