What Is a Pillow Sham? Definition, Types, and Uses

A pillow sham is a decorative pillow cover designed to transform a standard pillow into an aesthetic bedding accessory. Unlike a typical pillowcase, which is primarily functional, a sham features a “false front” — often with decorative fabric, trim, or detailing — and is typically open in the middle of the back with overlapping fabric or a hidden zipper. Originating in the 1700s, pillow shams were created to allow removable, washable covers for decorative pillows, combining practicality with style.

Pillow shams are commonly sold in pairs and made from fabrics that match duvet covers or bedding sets. While they can be slept on, they are primarily used for sitting up in bed or as daytime decoration. They are easily removed for washing or replacing the pillow insert.

Standard Pillow Sham Sizes

Pillow shams are made to fit standard pillow dimensions. The most common sizes include:

• Standard Sham: 20″ x 26″
• King Sham: 20″ x 36″
• Euro Sham: 26″ x 26″

These sizes correspond to standard, king, and European square pillows, respectively. Shams are designed to slightly overfill for a full, poofy appearance when used with a pillow insert.

How Pillow Shams Differ from Regular Pillowcases

While both pillowcases and shams cover pillows, their construction and purpose differ:

• Pillowcase: Open at one end, simple design, meant for nightly leverage and frequent washing.
• Pillow Sham: Often closed on all sides with a back opening (overlapping fabric or hidden zipper), decorative front, and intended more for display than sleep.

Unlike throw pillows, shams are designed to be easily removed from their inserts, allowing the cover to be washed or replaced without discarding the entire pillow.

Common Uses of Pillow Shams

Pillow shams serve both functional and decorative roles in bedding ensembles:

• Placed behind sleeping pillows for added support when sitting up in bed.
• Used as daytime decoration to enhance the visual appeal of a made bed.
• Removed entirely at night if preferred for sleeping.
• Coordinated with duvet covers, quilts, or bedspreads for a cohesive look.

Many shams are crafted from the same fabric as matching duvet covers, enabling a layered, coordinated bedroom aesthetic.

Materials and Care

Pillow shams are available in a variety of fabrics, including cotton, linen, silk, and blends. Cotton shams — especially those with a waffle weave — are popular for their breathability, softness, and ease of care. Most shams are machine washable, and because the cover is removable, they can be cleaned frequently without affecting the pillow insert.

For optimal appearance and longevity, it is recommended to use a down alternative or polyester fill pillow with a stain-resistant inner cover, as this helps maintain shape and resist wear.

Frequently Asked Questions

Can you sleep on a pillow sham?

Yes, pillow shams can be slept on like regular pillowcases, though they are often designed more for decoration. Many people place them behind sleeping pillows for comfort and remove them at night.

Do pillow shams come with inserts?

Typically, pillow shams are sold as covers only. Pillow inserts are purchased separately to match the sham’s dimensions.

How often should pillow shams be washed?

Since they are removable, pillow shams can be washed as frequently as desired — weekly or biweekly is common for those used nightly, while decorative shams may be washed less often.

Are euro shams only for European pillows?

Euro shams are designed for 26″ x 26″ square pillows, which are commonly used in European bedding but are also popular in the U.S. For decorative layering.
