A sham in bedding is a decorative pillow cover for display, while a pillowcase is the functional cover you sleep on every night.
One looks styled on a made bed; the other gets drooled on at 2 a.m. That’s the whole split, and confusing the two is why so many bedding sets end up short one cover on laundry day. A sham is built to be seen, not slept on.
What Actually Makes A Sham A Sham?
A sham is a decorative cover that usually slides over a pillow from a back opening, almost always trimmed with a flange, ruffle, cording, or buttons. The construction signals its job: it’s dressed for the room, not the sleeper.
The giveaways sit in the edges and closure. A sham typically opens along the back through an envelope overlap, hidden zipper, or buttons, and it often carries a flange — that flat fabric border running past the pillow’s edge — or decorative trim. Pillowcases skip all of it: they open at one end or the side and keep a plain hem, because their purpose is to go on and off a sleeping pillow fast, wash after wash.
Size runs differently too. Shams are often sized slightly larger than the pillow they cover so the cover fills out the corners and looks full on a made bed. That extra fabric is intentional, and it’s why a standard pillow stuffed into a matching sham can look a touch loose at the edges.
Can You Sleep On A Sham?
You can sleep on a sham only when it’s made from soft sheet-weight fabric with a simple closure — textured, beaded, corded, or buttoned shams are made for display and won’t feel comfortable against your face.
Plenty of people do it anyway, especially when a sham matches a duvet and the bed looks too good to disturb. It works fine if the sham is smooth cotton, sateen, or linen and opens without hardware digging into your cheek. Where it falls apart: anything with a tight flange that bunches, a zipper you can feel, or a beaded or embroidered face. Those belong propped against the headboard, not under your head.
The practical move is to keep sleeping pillows in pillowcases and reserve shams for the decorative pillows in front. If you’re building a full set and want shams and cases that match, a tested roundup of bed sheet sham and pillowcase sets worth buying can save you the guesswork on fabric and sizing.
| Feature | Sham | Pillowcase |
|---|---|---|
| Main purpose | Decorative display | Sleeping comfort |
| Typical opening | Back envelope, buttons, or zipper | Open end or side |
| Trim and edges | Flange, ruffle, cording, embroidery | Plain hem |
| Where it lives | On a made bed for styling | On the pillow you sleep on |
| Washing frequency | Less often — it’s decorative | Frequently — skin contact nightly |
| Sleepable? | Sometimes, if plain and soft | Yes, by design |
| Common sizing | Slightly larger than the pillow | Fitted to the pillow |
Sham Vs Pillowcase: Which Do You Wash More?
Pillowcases get washed far more often because they touch your skin and hair all night; shams get washed less since they’re mostly decorative. Real Simple’s bedding guidance points to the same split — cases are the workhorse, shams the showpiece.
A standard pillowcase can hit the wash every few days without wearing out, while a trimmed or beaded sham is better off on a gentler schedule, spot-cleaned when something spills and otherwise freshened occasionally.
Check the care tag before committing either to a hot cycle. Shams with cording, appliqué, or heavy embroidery often call for cold water and air drying so the trim doesn’t pucker or fray. Plain cotton shams can usually follow the same routine as your sheets. Keeping a second set of everyday pillowcases on rotation means the shams never have to leave the bed just because laundry day arrived.
The One Thing To Remember
Sham equals display, pillowcase equals sleep. Buy pillowcases for the pillows you rest on and shams for the pillows that just sit there looking good.
Reach for a sham when the bed needs styling — a pair behind your sleeping pillows, slightly oversized, matching the duvet. Reach for a pillowcase when the pillow is going under your head. Buy one more set of cases than you think you need, keep shams on a gentler wash schedule, and you’ll never again wonder why the matching “pillow cover” has buttons down the back.

FAQs
Is a sham the same as a pillowcase?
No. A sham is a decorative cover, usually with a flange or trim and a back opening, meant to style a made bed. A pillowcase is the functional cover you sleep on, with a simple open end or side and a plain hem. They look similar when plain, but they’re built for different jobs.
What size pillow fits in a sham?
Standard shams fit a standard 20-by-26-inch pillow, king shams fit a king pillow, and euro shams are square, typically 26 by 26 inches. Shams usually run slightly larger than the pillow inside so the cover fills out corners and looks full on a made bed.
Can you use a pillowcase instead of a sham?
You can, but the bed will look less styled. Pillowcases lack the flange, trim, and structure that give shams their decorative shape. If you want the layered look of a made bed, shams in front of your sleeping pillows get you there; plain cases alone read more casual and functional.
