These are basic and fine.  These won’t add to or subtract from your bed set up.  Which works really well for the largest pillows, for having too many pillows, or a big personality (color, pattern, texture) going on your beddecor.  These run large I have them(26x26) on my generously filled goose down  pillows(28x28) with a bit of room (as a headboard).  They should just barely fit.  If you’re buying shams and or the actual pillows, you go down a size up for the sham, from the measurements of the pillow.  Otherwise you end up with slouchy looking euro shams and writing a frustrated and idiotically naive review.  These are good, not great. The short zipper does make them difficult to put on and that bodes unwell for longevity.
