How Much Fabric Is Needed To Make A Pillowcase. 25 yards 23 meters of fabric for king size pillowcases 20 x 40. I recommend buying at least 10 more.

A finished standard pillowcase should measure about 225 inches by 315 inches allowing for fill depth seaming and an approximate 4-inch hem. For the width of the fabric take the pillow size and add 1 to allot for a seam allowance. A 16 pillow would be 17 making your fabric piece 17 x 38.
Start by cutting two identical size pieces of fabric that are each 295 inches long and 21 inches wide.
