Discover our pillow sizes chart and breakdown below.
No matter what size or type of pillow you need, Casper has a cozy cloud for you to rest your head on. Made with support and maximum comfort, our pillows are what dreams are made of.
From a standard to king size pillow – you probably didn’t realize how many pillow sizes were out there until you started shopping. Each has unique dimensions and is best fit for specific mattress sizes and types of sleepers. So while you may be okay with going the simple route and sticking with a standard pillow size, there’s a chance it’s not the pillow that would be best for you.

A standard pillow fits well on a twin or full-size mattress. With full mattresses being 53 inches (134.5 cm) wide, opting for two standard pillows would fill the width of the mattress. However, twin mattresses are much smaller and will only fit one standard pillow.
Being one of the smallest sleeping pillows you’ll find, it takes three standard pillows to cover the span of a king-size mattress. Because of this, normal sized pillow fills are not the best option for larger beds.

Being two inches longer than its little brother, the standard, and two inches shorter than the queen, super standard pillows are the perfect in-between.
Two super standard pillows are too long to fit across a full or full XL mattress but fit well on a queen. If you prefer only having or using one pillow, a super standard would work well on a twin or full-size mattress as well.
20 x 30 in | 51 x 76 cm
As the name suggests, queen size pillows work well on queen mattresses. With a mattress width of 60 inches, two pillows fit perfectly. If you prefer a more full look on a twin, one queen size pillow will do the trick.
Queen pillows fit snug in a standard-size pillowcase, so no need to buy a different size for them unless you prefer a looser look.

You’ll normally find king-size pillows on a king or California king mattress. While you could put a king-size pillow on a twin bed instead of a king size bed, there will only be about one inch of the mattress on each side of the pillow. If this is what you’re aiming for, or a king-size pillow is best for your sleep patterns, this would be a good pillow for you.
Keep in mind that the size of this sleeping pillow doesn’t fit in a standard pillowcase. Be sure to purchase pillowcases that specifically say they fit king-size pillows.

Body pillows may not come to mind when thinking of other pillow sizes out there, but don’t count out using one regularly. With the longest length out of all the aforementioned sizes, they only fit across queen or king-size beds.
Each Casper pillow is designed with different sleepers in mind, resulting in unique features. Our Original Casper Pillow, Memory Foam Pillow, and Down Pillow all come in either a mid loft or low loft height as well.
The “loft” of a pillow refers to its height when laying flat. A pillow with a low loft is a thinner pillow, while a pillow with a high loft will be thicker. Depending on your normal sleeping position, you’ll want a specific loft in order to be most comfortable.
For example, it’s best for a stomach sleeper to have a low loft pillow to keep their spine as aligned as possible. Using a medium or high loft pillow may be uncomfortable and can cause aches and pains – while side or back sleepers may prefer to have such a loft to sleep on.
While standard, super standard, queen, king, and body pillows are among the most popular for sleeping, there are a few other types of pillows that can be used for different occasions as well.
Measuring a pillow doesn’t seem to be a hard task, but when done incorrectly, you’ll get inaccurate measurements. Rather than using a soft, tailor’s measuring tape, use a firm, carpenter’s tape measure. Hold two corners of the pillow to the ground and measure from one end to the other.
When measuring, make sure not to do so diagonally or from the center to any side of the pillow. You’ll also notice the pillow dimensions listed above are all whole numbers. It may take some rounding, but your measurements should be whole numbers as well.
We’re all different and therefore need different pillows. Now that you’ve read through our guide to different pillow sizes, you know how to find the the right pillow that will be best for you and your needs.
