A tad bigger than other standard size-easier to slide the pillow in. Thick, well-made, smooth material can't see through to the pillow. I can tell these will last after several washes and will last a long time. Edges don't wrinkle easy after washing like some cases I have had. Even comes in a cute little package. Would be a great gift for sending the kids off to college! If there are other colors, I would purchase more! Don't think my pictures do these nice cases justice.
