If you've ever stared at a bed set wondering whether you need shams, pillowcases, or both, you're not alone. A pillow sham is a decorative cover designed to dress your bed during the day, while a pillowcase is the functional cover you actually sleep on at night. Understanding the pillow sham vs pillowcase distinction takes about two minutes, and it will change how you shop for bedding.

The Short Answer, Sham vs Pillowcase
A pillow sham sits on top of your bed for visual effect. It typically features a decorative flange (a flat border), a more formal fabric like jacquard or embroidered cotton, and a hidden back closure. You remove it before sleep.
A pillowcase does the opposite job: it protects the pillow you rest your head on and stays on through the night. It's made from soft, skin-contact fabrics, percale, sateen, or lyocell, and usually has a simple open-end or envelope closure. Most beds need both.
What Is a Pillow Sham?
A pillow sham is built to look good, not to be slept on. The signature feature is the flange, a flat fabric border, usually 1" to 3" wide, that frames the pillow like a picture. Shams are made from heavier or more textured fabrics: woven cotton, linen blends, velvet, jacquard, or embroidered cloth. These materials photograph beautifully but would feel stiff or rough against bare skin after a few hours.
The back of a sham uses either an envelope overlap (two panels of fabric that cross in the center) or a hidden zipper. Neither is designed for quick daily removal the way a pillowcase is, shams are meant to stay on while the bed is made and come off as a set when you turn down the covers.
Sham sizing runs larger than its matching pillowcase because the flange adds width. A standard sham fits a standard or queen pillow but measures noticeably bigger overall once that border is included. Shams also come in queen, king, and Euro sizes, the last being a square format with no matching pillow size at all.
Shams are sold as part of comforter sets or as standalone accents. They're the pieces that make a bed look like a hotel or a magazine spread. See our guide to pillow shams for a deeper look at styles and sets.
What Is a Pillowcase?
A pillowcase is the cover that touches your face and hair for six to eight hours every night. That skin contact makes material quality matter far more than it does for a sham.
Construction is intentionally simple. Most pillowcases use an open-end design, the pillow slides in from one open end, which may have a small interior flap (called an envelope closure) to hold the pillow in place. Some higher-end sets use a zipper, but the open-end version remains standard because it's easy to strip off and wash frequently.
Common fabrics for pillowcases:
- Percale cotton, crisp, cool, breathable. A thread count between 200 and 400 is the sweet spot. Good choice for hot sleepers. See our percale vs linen comparison for more detail.
- Sateen cotton, silkier hand feel, slightly warmer. Works well in cooler climates or for sleepers who run cold.
- Lyocell (Tencel), moisture-wicking, temperature-regulating, naturally smooth. An increasingly popular choice for people who wake up hot.
- Microfiber, low cost, durable, but less breathable than natural fibers.
Standard pillowcase sizing (20" x 26") fits both standard and queen pillows. King pillowcases are cut wider at 20" x 36" to fit the longer king pillow. For a full breakdown, visit our typical pillow sizes guide.
Size Comparison Table
| Type | Dimensions | Fits Pillow | Purpose |
|---|---|---|---|
| Standard Pillowcase | 20" × 26" | Standard / Queen pillow | Sleeping |
| Standard Sham | 20" × 26" + flange | Standard / Queen pillow | Decorative |
| Queen Sham | 20" × 30" | Queen pillow | Decorative |
| King Pillowcase | 20" × 36" | King pillow | Sleeping |
| King Sham | 20" × 36" + flange | King pillow | Decorative |
| Euro Sham | 26" × 26" | Euro square pillow | Decorative only |
Note: Euro shams are square and decorative only. There is no standard sleeping pillow in this size, the Euro pillow is sold specifically to fill the sham.
When to Use Which (Or Both)
Most beds are made with both, and the routine is straightforward: shams go on in the morning when you make the bed, pillowcases stay on through the night.
A typical hotel-style setup for a queen bed:
- Two queen pillows with pillowcases (for sleeping, tucked toward the headboard)
- Two standard or queen shams (placed in front of or over the sleeping pillows during the day)
- Two Euro shams at the back, leaning against the headboard
At bedtime, the shams and Euro pillows come off and get set on a bench, chair, or the floor. The sleeping pillows stay on with their pillowcases. That's it.
Guest rooms benefit most from shams, the bed looks polished without needing to be stripped and remade constantly. For an everyday bedroom used by a single person who doesn't make the bed formally each morning, two pillowcases alone is perfectly functional. Shams are a choice, not a requirement.
If you're pairing shams with a great pillow, our best cooling pillows for 2026 roundup covers options that work well under either cover type.
Materials and Quality
Because a sham never touches your skin during sleep, the material decision is entirely aesthetic. Thicker, stiffer textiles, woven cotton, velvet, linen, hold their shape better and photograph well. Durability matters only in terms of how well the fabric resists fading and pilling on display, not how it feels on contact.
Pillowcases are a different calculation. You spend roughly a third of your life with your face on a pillowcase. That makes fabric choice a genuine sleep quality decision, not a style one.
Percale is the most recommended fabric for people who run warm. Its one-over-one-under weave creates a crisp, breathable surface that resists heat retention. Thread counts between 200 and 300 in long-staple cotton perform better than 600+ thread count sateen, which traps more heat despite feeling luxurious at first touch.
Lyocell is worth considering if night sweats are a concern, it wicks moisture efficiently and has a naturally smooth surface that causes less friction on hair. Sateen (like the cotton sateen sold by brands such as Saatva) offers a silkier feel that some sleepers prefer, particularly in winter months.
Where to invest: quality pillowcases justify a higher price because they directly affect sleep comfort and skin health. A sham is background scenery, mid-range fabric is entirely sufficient unless you're matching a specific decor.
FAQ
Are pillow shams the same as pillowcases?
No. They serve different purposes and are constructed differently. A sham is decorative and uses heavier fabric with a flanged border. A pillowcase is functional, made for sleep contact, and built for frequent washing.
Can you sleep on a pillow sham?
Technically yes, but it's not comfortable. Sham fabrics are stiffer and the flange creates an uneven surface. For regular sleep use, a standard pillowcase is always the better option.
Do you put pillowcases inside shams?
No. The pillow itself goes inside the sham for display. At night, you remove the sham and sleep directly on the pillow in its pillowcase. You're not layering both covers on one pillow simultaneously.
What sizes do shams come in?
Standard (20" × 26" + flange), queen (20" × 30"), king (20" × 36"), and Euro (26" × 26"). Most bedding sets include standard shams; queen and king shams are usually sold as upgrades or within full bedroom sets.
What is a Euro sham?
A Euro sham is a square decorative pillow cover measuring 26" × 26". It requires a Euro square pillow insert, which is sold separately and is not a sleeping pillow. Euro shams are purely decorative and are typically placed at the back of a layered bed arrangement against the headboard.
Do shams have pillows inside them?
Yes, a pillow (or pillow insert) goes inside the sham to fill it out. For standard, queen, and king shams, this is usually the same pillow that later gets used for sleeping. For Euro shams, you need a separate 26" × 26" Euro pillow insert.
Our Sleep Lab Pick, Best Pillowcases and Sham Sets
For the pillowcase specifically, prioritize long-staple percale or lyocell. Both breathe well, soften with washing rather than degrading, and hold up to the frequent laundering pillowcases require (ideally weekly).
For shams, match your comforter or duvet cover material, most sets include matching shams, and coordinating the entire layer avoids mismatched textures that flatten the visual effect of a well-made bed.
Amerisleep's bedding line covers both sides of this equation: their pillowcases and matching sham sets are made from a moisture-wicking, temperature-regulating fabric that works whether your priority is sleep comfort or bedroom aesthetics. Through , Amerisleep is running its Current Sale with $500 off, their bedding category at amerisleep.com/bedding/ includes pillowcases, shams, and complete sheet sets.
