A king size pillow is designed to fit a king-size bed. It’s vital to keep in mind when purchasing sheet sets and shams that these pillows do require a larger king-size pillowcase. If you want to place a larger cushion on a smaller bed, one king-size pillow will just fit on a twin-size bed with about an inch on each side to spare. Many customers prefer to sleep on their king beds with a smaller queen sized cushion since they find the extra length and weight to be burdensome.
