When it comes to bedding, the size of your pillowcase is just as important as the size of your pillow or mattress. 

Pillowcases not only protect your pillows but also play a key role in enhancing your comfort and bedroom aesthetics. 

This guide will walk you through the various pillowcase sizes, helping you make informed decisions for a perfect night's sleep.

Standard Pillowcase Sizes Explained

Choosing the right pillowcase size starts with understanding the standard options available. 

These sizes are designed to fit most pillows and beds, ensuring a snug fit and polished look.

Standard Size Pillowcases

Standard pillowcases measure 20 inches by 26 inches (51 cm by 66 cm). They’re crafted to fit standard pillows and are ideal for twin, twin XL, and full-size beds. If you have a queen-size bed, two standard pillows placed side by side can also work, offering flexibility and versatility.

Queen Size Pillowcases

Queen pillow cases are slightly larger at 20 inches by 30 inches (51 cm by 76 cm), adding 4 inches of extra length compared to standard sizes. This additional coverage is great for restless sleepers and is specifically designed for queen-size pillows. 

While queen pillowcases are perfect for queen beds, they’re also compatible with full and king-size beds for added adaptability.

King Size Pillowcases

The largest of the standard options, king pillowcases measure 20 inches by 36 inches (51 cm by 92 cm). These pillowcases are tailored for king-size pillows, providing ample coverage for king and California king beds. 

Their extra length and size make them a popular choice for individuals who require additional support or for those who toss and turn during sleep.

Understanding standard pillowcase sizes ensures your pillows stay protected and your bed looks well coordinated. Whether you need compact standard sizes or the generous proportions of king sizes, there’s an option to suit every preference.

Specialty Pillowcase Sizes

In addition to standard sizes, there are specialty pillow cases designed for specific purposes or unique pillow shapes. 

These options cater to decorative needs, body support, or unconventional pillow dimensions.

Euro Pillowcases

Euro pillowcases are 26 inches by 26 inches (66 cm by 66 cm), offering a square shape perfect for decorative Euro pillows. Often used as accent pieces, Euro pillows add a layer of sophistication to your bedding while doubling as back support when sitting up in bed.

Body Pillowcases

Body pillowcases are the longest, measuring 20 inches by 54 inches (51 cm by 137 cm). These cases are designed to fit body pillows, which provide full-body support and are particularly popular among pregnant women and side sleepers.

Super Standard Pillowcases

At 20 inches by 28 inches (51 cm by 71 cm), super standard pillowcases are a less common size that serves as a middle ground between standard and queen sizes. They offer a bit more room than standard sizes without the added length of a queen case.

Specialty pillowcase sizes cater to unique needs, whether you’re decorating with Euro pillows or seeking additional support with a body pillow. These options ensure both functionality and aesthetic appeal.

How to Measure Pillows for Correct Pillowcase Size

Choosing the right pillowcase starts with ensuring your pillow measurements align with standard or specialty pillowcase sizes. 

Here's a step-by-step guide to help you measure accurately:

Step 1: Remove the Current Pillowcase

Begin by removing any existing pillowcase or cover to expose the pillow itself. This ensures you’re measuring the pillow directly without interference from excess fabric or seams.

Step 2: Lay the Pillow Flat

Place the pillow on a flat, hard surface like a table or bed to ensure it remains steady during measurement. A flat surface helps maintain the pillow's natural shape, which is essential for accurate results.

Step 3: Measure the Width and Length

Use a flexible measuring tape to measure the pillow’s width and length. Measure from seam to seam along the widest part of the pillow for both dimensions. Ensure the tape lies flat and follows the natural shape of the pillow.

Step 4: Focus on the Bottom Edges for Consistency

For the best accuracy, measure along the bottom edges of the pillow. This avoids discrepancies caused by any tapering or irregularities in the pillow’s shape.

Step 5: Account for Pillow Fluffiness

If the pillow is particularly fluffy or thick, apply gentle pressure to flatten it slightly while measuring. This ensures the measurements reflect the pillow's actual size when placed in a pillowcase.

Step 6: Match Your Measurements to Standard Sizes

Compare your measurements to the most common pillow sizes:

  • Standard Pillowcases: 20" x 26" (51 cm x 66 cm)

  • Queen Pillowcases: 20" x 30" (51 cm x 76 cm)

  • King Pillowcases: 20" x 36" (51 cm x 91 cm)

  • Body Pillowcases: 20" x 54" (51 cm x 137 cm)

Measuring your pillows correctly guarantees a perfect fit, improving not only the appearance of your bedding but also your sleeping experience.

Key Factors in Choosing Pillowcase Size

Selecting the right pillowcase isn’t just about fit—it’s also about comfort and aesthetics. 

Keep these key factors in mind:

  • Bed Size: Match the pillowcase size to your bed size. For example, use king pillowcases for king beds to maintain proportionality and visual harmony.

  • Pillow Size: Ensure your pillowcase dimensions match the exact size of your pillows to avoid bunching or sagging.

  • Sleep Position: Your sleep position can influence your choice. Side sleepers may prefer larger pillows and cases for added support, while back sleepers often find standard sizes more comfortable.

  • Aesthetic Preferences: Pillowcases can enhance your bedroom’s overall look. Choose sizes and designs that complement your decor and create a cohesive, inviting space.

By considering bed size, pillow size, sleep habits, and design preferences, you can select pillowcases that align with both your practical and aesthetic needs.

Summary and Recommendations

Pillowcases are more than just decorative covers—they’re essential for protecting your pillows and enhancing your sleep experience. 

Whether you’re outfitting a king bed or looking for the perfect body pillow cover, understanding the different sizes and their functions ensures you make informed choices. 

Pairing the right size with high-quality materials creates a cozy, supportive sleep environment, helping you rest better and wake up refreshed.

Yes Heavanet, I think using queen pillow cases will solve your problem. Pillow cases are often made of cotton, and they shrink over time. When you start with larger pillow cases in the first place, they will fit wash after wash.

Good idea Rundocuri, I'll have to give that a try. I am always tugging and shaking at my pillows to get them back inside the cases. I hadn't thought of trying larger pillow cases.

I like to use queen sized pillow cases on my standard pillows. They fit better, and prevent the pillows from popping out of the cases.
