What Is a Sham? Let’s End the Confusion

May 10, 2021 | Casper Editorial Team

If you’ve ever asked yourself, “What is a sham?” or “What is a pillow sham?,” you’re in the right place. Often referred to interchangeably as a sham, pillow sham, or bed sham, these pillow covers turn traditional-sized pillows into decorations for your bed. While similar to a normal pillowcase, they often have a more decorative front and an opening in the back rather than the end.

Because of its decorative nature, you’ll often use a regular pillow sham strictly as an accessory or to prop you up in bed while reading or relaxing. You can sleep on them, although the decorative pillow may not be the most comfortable. Additionally, depending on the type of decoration covering the front, they can be more laborious to wash than regular pillowcases.

From shams to regular pillowcases, Casper has all the bedding you need to create your dream sleep setup. Browse our selection today and be on your way to a cozy snooze tomorrow.

When to Use a Bed Sham

If you’re looking for a simple way to style your bedroom differently, a pillow sham or two can do the trick — without you having to purchase all new pillows. 

Generally, you would place bed shams and accent pillows in front of your sleeping pillows during the day to give the bed your desired look. At night you can place them behind your sleeping pillows to prop yourself up or toss them off the bed before going to sleep.

What’s the Difference Between a Sham and a Pillowcase?

One prevalent difference between a sham and a pillow cover is the location of the opening. While not always the case, pillowcases typically have an opening at one end with excess fabric hanging off the side and no type of closure. A pillow sham typically has either a zipper along one edge or an opening on the back with an envelope-style closure.

Aside from the opening location, a pillow sham often has flange or cording around the edges and a more decorative front, whereas a pillowcase is often plain and used to protect your pillow from body oils and dirt while you sleep.

How to Pick the Right Sham Pillow

Knowing what size pillows you’d like to transform into bed accessories is the first step to picking the right bed sham. If it won’t fit the pillows you already have, it’s not worth the purchase unless you’re willing to purchase new pillows as well. Since matching pillow shams typically come in your standard pillow sizes, all you need to know is what size pillow you want it to cover.

Another consideration is whether or not a pillow sham will match your duvet, comforter, and other types of pillows. While decorative shams occasionally come in a duvet and sheet set, sometimes you may need to purchase them separately. Aside from these two points, another thing to consider is the style of the sham, which depends entirely on your preference.

What Kind of Pillow Goes in a Sham? 

As mentioned previously, bed shams are made to fit traditional sleeping pillow sizes. If you’re unsure what kind of pillow you need to have for each pillow sham size, measure it to see if it will fit in the dimensions below.

  • Standard sham: 20 inches by 26 inches
  • Queen sham: 20 inches by 30 inches
  • King sham: 20 inches by 36 inches

What is a Euro Pillow Sham? 

A Euro sham is a decorative covering for a Euro-sized pillow. Euro pillows are typically 26 inches by 26 inches and Euro shams are made to fit over them. They play the same role as other-sized bed shams, just for a nontraditional-sized pillow. Similar to other pillow shams, a Euro sham will typically coordinate with the duvet and bedding to tie the look together.

When redecorating, trying to change the feel of a room, or just out shopping, it’s normal to ask yourself, “What is a sham?” It can be particularly confusing when faced with the decision to buy a pillowcase or pillow sham. 

Keep in mind that one of the overarching differences between the two is the amount of decoration on each. Pillowcases are plain and show little decoration aside from the occasional printed design. If you want something a little more fancy that can be removed, washed, or replaced easily, a pillow sham is the way to go. But don’t forget to grab a coordinating throw blanket or sheet set to make your bedroom feel polished and complete.
