If you’re looking to buy new bedding, you might wonder what size is a standard pillow case. It’s a common question, as getting the right fit is key for both comfort and appearance.
Standard pillowcases are designed to fit a standard pillow, which is the most common size used on beds. This size fits what many people consider a “normal” bed pillow. Knowing this measurement helps you shop confidently and ensures your bedding looks neat and stays put all night.
What Size Is A Standard Pillow Case
A standard pillow case typically measures 20 inches by 26 inches. This is meant to fit a standard pillow insert that is 20 inches by 26 inches. The case is cut slightly larger to allow for the pillow’s fullness and seams.
It’s the go-to size for twin, full, and double beds. You’ll often find them sold in pairs or as part of a bed sheet set. When you buy a basic set of sheets, it usually includes one or two of these standard cases.
Why the Exact Fit Matters
Using the correct pillowcase size is more important than it might seem. A case that’s too small will stretch and tear at the seams. It will also make your pillow feel lumpy and uncomfortable.
A case that’s too large will look sloppy and wrinkled. The pillow will shift around inside, which can be annoying while you sleep. The right fit provides a smooth, tailored look for your bed.
How to Measure Your Pillow for a Case
If you’re unsure about your pillow’s size, it’s easy to check. Here’s how to do it:
- Lay your pillow flat on a bed or table.
- Use a fabric measuring tape for accuracy.
- Measure the width from one seam to the other (the shorter side).
- Measure the length from seam to seam (the longer side).
- Note down both dimentions in inches.
Once you have these numbers, you can compare them to standard case sizes. Remember, your pillowcase should be about 1-2 inches bigger than the pillow itself.
Other Common Pillow and Pillowcase Sizes
While “standard” is most common, pillows come in many sizes. Your bed might use a mix. Here’s a quick guide to other typical sizes:
- Queen Pillow Case: Measures 20 inches by 30 inches. Fits queen-sized pillows, often used on queen, king, or full beds for a larger look.
- King Pillow Case: Measures 20 inches by 36 inches. Designed for king-sized pillows, which are longer to fit the width of a king bed.
- Euro Pillow Case: Measures 26 inches by 26 inches. These are square decorative shams often used for sitting up in bed.
- Travel / Bolster Case: Various small sizes, like 12 inches by 16 inches, for decorative or travel pillows.
Pillowcase Closures: Envelope, Zipper, or Open?
How a pillowcase stays closed also affects the fit and look. The main types are:
- Open End: The classic style. You just tuck the pillow in. It’s simple but the pillow can sometimes slip out.
- Envelope Flap: Has an overlapping fabric flap inside that keeps the pillow hidden and secure. It offers a neat, tailored appearance.
- Zipper Closure: Less common for standard cases, but used on some decorative shams. It fully encloses the pillow but the zipper can feel uncomfortable if touched.
The envelope closure is a popular choice because it combines security with a clean look without extra hardware.
Fabric and “Finish” Sizes
Did you know fabric can affect the final size? Cotton and linen can shrink when washed. Many manufacturers pre-wash fabrics or account for shrinkage.
Always check the label for terms like “finished size” or “post-wash size.” If it says “may shrink up to 5%,” your 20×26 inch case could become slightly smaller. Buying from reputable brands usually means they’ve managed this shrinkage for you.
Choosing the Right Pillowcase for Your Bed
Matching your pillowcases to your bed size creates a balanced look. Here are some typical arrangements:
- Twin Bed: Use one standard pillow in a standard case.
- Full/Double Bed: Use two standard pillows in standard cases.
- Queen Bed: Often uses two queen pillows in queen cases. Some prefer two standard pillows for a more layered look with shams.
- King Bed: Typically uses two king pillows in king cases. Sometimes, people use three standard pillows across instead.
Layering different sizes, like standard pillows in front of euro squares, adds depth and style to your bed’s design.
Step-by-Step: Putting on a Pillowcase Correctly
It might sound silly, but there’s a trick to getting a pillow into its case easily and without a struggle.
- Turn the pillowcase inside-out by reaching in and grabbing the bottom seam.
- With the case still inside-out, grab the corners of the pillow and the corners of the case.
- Shake the case down over the pillow, letting it roll right-side-out as it goes.
- Adjust the pillow into the corners and smooth it out.
This method is faster and puts less strain on the seams than pushing the pillow in from the open end.
Care and Maintenance for Longevity
Taking good care of your pillowcases makes them last longer and keeps them looking fresh. Follow these tips:
- Wash them regularly, at least once a week, to remove oils and skin cells.
- Use a mild detergent and avoid excessive bleach, which can weaken fibers.
- Tumble dry on a low heat setting to prevent overwheming shrinkage.
- Iron if needed on the appropriate fabric setting while the case is slightly damp.
- Rotate between multiple sets to reduce wear and tear on a single pair.
Common Mistakes When Buying Pillowcases
Avoid these errors to ensure you get the right product for your needs.
- Assuming “Standard” is Universal: Always double-check the listed dimensions, as some brands might vary slightly.
- Forgetting About Pillow Loft: A very thick, fluffy pillow might need a “deep pocket” case even if its length and width are standard.
- Ignoring Thread Count Myths: A very high thread count isn’t always better. Focus on fabric quality (like long-staple cotton) and weave.
- Not Buying Extras: It’s wise to have a spare set or two for when others are in the wash.
Specialty and Decorative Options
Beyond basic cases, you have many choices to express your style.
- Decorative Shams: These are often larger and stiffer than regular cases, used in front of sleeping pillows for style. They usually match the bedspread.
- Oxford Cases: Have a decorative hem or flange around the edge for a more formal, furnished look.
- Patterned & Textured Weaves: Like jacquard or embroidered cases, which add visual interest.
Remember, shams are usually decorative. You’ll often slip your standard pillow (in its regular case) inside a sham for sleeping.
Where to Buy Standard Pillow Cases
You can find standard pillowcases almost anywhere that sells home goods. Here are the main places:
- Department stores (like Macy’s, Target, Walmart)
- Bedding specialty stores
- Online retailers (Amazon, Wayfair, direct brand websites)
- Home goods stores (like HomeGoods/TJ Maxx)
When shopping online, always read the product description carefully to confirm the size and fabric content. Customer photos can be very helpful too.
FAQs About Pillowcase Sizes
Is a standard pillowcase the same as a twin pillowcase?
Yes, they are generally the same size. The term “standard” and “twin” are often used interchangably for the 20×26 inch pillowcase size.
Can I put a queen pillow in a standard pillowcase?
You can try, but it will be very tight. A queen pillow is 4 inches longer, so it will overstretch the seams and likely tear the fabric. It’s not recommended.
What if my pillow is thicker than usual?
Look for “deep pocket” or “extra deep” pillowcases. These are cut wider to accommodate pillows with high loft (like down or memory foam) without straining.
How many pillowcases come in a standard sheet set?
It depends. A set for a twin bed often includes one. A set for a full, queen, or king bed usually includes two standard or size-specific pillowcases. Always check the set contents before buying.
Are pillow sizes universal in every country?
No, they are not. For example, standard pillows in the UK and Australia can be different. If you’re buying internationally, always check the dimensions in inches or centimeters to be sure.
What’s the difference between a pillowcase and a pillowslip?
They are essentially the same thing. “Pillowslip” is just an older or more formal term for a pillowcase. The function and size are identical.
Can I make my own pillowcase?
Absolutely! It’s a great beginner sewing project. You just need fabric, a sewing machine, and a simple pattern. Remember to account for seam allowances and possible shrinkage when cutting your fabric.
Choosing the right pillowcase size is a small detail that makes a big difference. It ensures your bed looks tidy, feels comfortable, and your bedding lasts for years. Now that you know what size is a standard pillow case and how it fits into the bigger picture of bedding, you can shop with confidence. Always measure your pillows before you buy new cases, and consider both function and style to create the perfect sleep setup for your home.
