Shams can be bought for standard or square pillows
Yes, pillow shams come in different sizes. A pillow sham is basically a decorative cover for pillows. Most typically have the opening in the back, which may or may not overlap. The sides will have a fabric or lace edging that gives a ruffled look. Common shapes are squares or rectangles and sometimes the cylindrical/neck roll can be found.
I think shams are basically one size.....fits all.
