How to Choose Bed Sheets: Sheet Buying Guide

October 20, 2021 | Casper Editorial Team

The world of bed sheets is a dreamy one, filled with several options of plush fabrics in a variety of thread counts, weaves, and styles to carry you into sleeping bliss. However, with so many options, this simple decision can become more complicated than securing a fitted sheet to your mattress.

To purchase the best sheets for your bed, first, consider your comfort needs. Do you love to sink into warm, flannel layers, or do you prefer to sleep more lightly under a satin sheath? 

No matter your preference, this sheet buying guide is designed to simplify your search for the perfect sheet with an in-depth look into thread count, weave, mattress size, and bedding. 

Casper’s selection of dreamy bed sheets makes your search for new bedding easier than ever. Whether you want light, breathable sheets that will keep you cool or warm, cozy sheets, we have what you need.

Pick Your Fiber and Material

When considering how to choose bed sheets, the material you pick may actually have a significant impact on your quality of sleep. 

For example, a scratchy fabric like wool may have you dreaming of bed bugs, while a silk sheet can carry you into a deep and comfortable sleep. However, when it comes to the different types of sheets, four fabrics reign supreme in terms of comfort and durability:

Percale

Percale sheets are typically made from organic cotton threads woven in a tight pattern.1  They can also be made from other fibers, including:

  • Polyester
  • Rayon
  • Microfiber

People love percale sheets because of the crisp, light feeling they offer against their skin. Percale sheets are also:

  • Soft
  • Durable
  • Breathable

If you’re searching for 100% organic cotton bedding, then you’ll want Casper’s percale sheet sets to keep you cool and comfortable as you sleep and away from harmful chemicals and pesticides.

Sateen

Sateen sheets can also be made from many different woven materials. Cotton threads create the smoothest touch and will make you feel like you’re sleeping in a luxuriously soft bed. Sateen sheets like Casper’s offer many benefits, including:

  • Wrinkle-resistance
  • Luscious feel
  • Incredible softness
  • 100% organic cotton threads

Even better, the more you sleep on these sheets, the softer they get. To see how this type of sheet stacks up against percale sheets, check out our comparison of percale vs. sateen sheets.

Flannel

As the temperatures drop outside, we seek cozy comfort inside. And nothing says warm and toasty quite like flannel. For the iciest of winter nights, you may want to wrap yourself in a thick flannel sheet. 

If you’re worried about getting too hot at night when you cozy up with heavy bedding, there are options for maximum comfort. Look for flannel sheets, like Casper’s, that are made with 100% organic cotton in a smooth, satin weave. Its lightweight breathability will keep you warm throughout the night without the sweat. You won’t need to worry about turning up the heat.

TENCEL™

Relatively new to the fabric world, TENCEL fibers are a material made from weaving sustainably sourced natural fibers, such as eucalyptus wood pulp. The result is a product that is:

  • Lightweight
  • Breathable
  • Cool
  • Soft
  • Sustainable

If you’re a hot sleeper who needs sheets that allow for maximum airflow, then Casper’s cooling sheets, made of 100% TENCEL™ Lyocell, might be right for you.

Understand Thread Count

There has been a lot of chatter surrounding thread count over the last decade. Often the conversation is framed to imply that a higher thread count means better sheets. But that’s not necessarily true.

Thread count refers to the number of threads in one square inch of fabric and indicates how soft the sheets will feel against your skin.2 To that end, the higher the thread count is, the softer your sheets will feel. 

However, there’s no need to invest in sheets with extremely high counts since the difference in feel isn’t likely to be noticeable enough to justify the enormous price difference.

A simple breakdown of common thread counts includes:

  • Flannel – 80 to 120 thread count
  • Linen – 80 to 140 thread count
  • Microfiber, like muslin – 140 to 180 thread count 
  • Jersey – 150+ thread count
  • Cotton – 200 to 400 thread count
  • Percale weave – 200 to 400 thread count 
  • Santeen – 300 to 600 thread count
  • Silk – 400+ thread count

Does Thread Count Matter?

To an extent, yes, thread count matters—you don’t want to feel like you’re sleeping between two sheets of sandpaper. In that case, what is the best thread count for sheets? if you’re looking for a comfortable and cheap option, 250 to 300 thread count sheets will do the trick. 

Consider the Weave

In bed sheet terminology, weave refers to the texture of the sheets and can influence the wrinkle-resistance of your bedding. 3There are three types of weave styles to consider when learning how to choose sheets, including:

  • Combed cotton – The creation of combed cotton fabric for bed sheets involves running a fine-toothed brush over the thread before spinning the fabric. This removes the shorter fibers and makes the remaining fibers straighter, resulting in sheets that are very strong and soft.
  • Percale – Percale bed sheets have tightly woven threads. The weave pattern is simple — one thread crossed under and one crossed over. They’re very durable and have a crisp, cool feel. Percale is known to last for a long time due to the pill resistance of the close percale weave.
  • Sateen – Sheets with a sateen weave are crafted with a unique spinning technique.4 To create the silky feel, a pattern of one yard under for every three of four over is utilized. Sateen in this context refers to the weave, not the material. Sateen weave sheets can be made from many different types of yarn.

Determine Your Sleeping Needs

The next step to understanding how to buy sheets for your bed is to consider your preferences. Are you sweating through the night or do you shiver at the thought of getting out of bed? Do you prefer soft cotton or a satiny feel against your skin as you sleep? 

When choosing your sheets, consider the following:

  • Hot sleeper – If you get too hot during the night, you should consider a TENCEL fiber or percale sheet set to increase breathability and airflow while you sleep to keep you cool.
  • Cold sleeper – When winter nights leave you shivering, flannel sheets will keep you warm and toasty, without making you sweat.
  • Texture – Craving supremely smooth softness? Then you should consider a sateen sheet set. However, for a crisper, cooler, and softer feel, a percale sheet set will provide the ideal level of light and breezy comfort.

Select the Right Sheet Size

The correct bed sheet size is critical to the comfort of your sheets. You don’t want them to come loose and tangle around your legs while you sleep, but you also won’t want them to be so tight that every laundry day becomes a wrestling match with your bed. 

There are two things you need to measure to ensure a proper sheet fit: the mattress size and depth.

Typical Sheet Sizes for Mattresses

The most common sheet sizes for mattresses include:5

  • Twin Sheets 38”W x 75”L
  • Twin XL Sheets – 38”W x 80”L
  • Full Sheets – 54”W x 75”L
  • Queen Sheets – 60”W x 80”L
  • King Sheets – 76”W x 80”L
  • California King Sheets – 72”W x 84”L

These are standard mattress sizes. However, mattress depth has a wider variance and no set standard.

Mattress Depth

A mattress can range from 8 to 14 inches in depth. However, if you include a mattress topper you can add two to four inches of fluff to your mattress, which means you may need larger sized sheets.

As such, measure your mattress carefully to make sure you’re purchasing a sheet set that fits your bed properly. 

Don’t Forget the Pillows

Pillows are the plush cushions that cradle your head as you drift off into dreamland. As such, choosing the right size may affect how quickly you get there. Generally, pillows come in three bed-coordinating sizes:

  • Standard – 20” x 26”
  • King – 20” x 36”
  • Euro – 26” x 26”

If you’re purchasing a pillowcase separately from your sheets, you’ll want to buy a pair that fits your pillow size and matches the material, thread count, and weave of your sheets. 

Coordinate Your Bedding

While sheets should provide comfort to your body, they should also be pleasing to the eye. Consider coordinating the color and pattern of your sheets with your bedroom aesthetic—are you aiming for a cool, airy suite or a cozy chamber with bold fabrics?

Some design aspects we love to see in sheet sets include:

  • Solid colors – Sheet sets in soothing solid colors create a calming atmosphere in your bedroom that gets you ready to settle in for a solid night of sleep. Neutral tones are a timeless choice.
  • Matching duvet covers – Make your bedroom decorating easier when you purchase a Casper sheet set that includes a matching duvet cover. This eliminates the need to hunt for a coordinating comforter. As a bonus, duvet covers are easy to remove and clean.
  • Pillowcases – Bed sheet sets that include pillowcases and the option to purchase additional cases if needed are a convenient way to make sure your bedding is streamlined and cozy.
