What is the Highest Thread Count for Sheets?

When it comes to judging the quality of sheets, most people immediately look at the thread count. A common misconception with thread count is that the higher the number, the better the sheet. Because it’s viewed as the biggest determinant of quality, bedding brands aim to create the highest count sheets. Unfortunately, many brands manipulate their products and sometimes, are not truthful.

In recent years, a number of bedding brands have been called on the carpet for marketing their products as having a higher number of threads than they actually do. In 2017, the International Trade Commission issued a general exclusion order banning bedding companies from importing sheets with exaggerated thread counts. Brands in India, China, and Pakistan were caught advertising their products with a grossly inflated counts, which triggered this crack-down by the ITC. Because of the prevalent misleading marketing amongst the bedding industry, many people end up splurging on sheets they believe to be of high-quality only to find out they don’t hold up well.

In this guide, we’ll explain what thread count is and why it’s not the most telling factor in determining which bedding is best for you.

What is Thread Count?

Thread count (TC) is the number of horizontal and vertical threads weaved in one square inch of fabric. The lower the count, the more light and breathable a sheet is, whereas high TC sheets are generally heavier and cozier. When looking at bedding sets, the number of threads is important to consider, but because it’s so commonly manipulated, is not always reliable.

Let’s talk about the tactics bedding brands use to inflate their thread count.

Common Marketing Misconceptions

One of the most common ways bedding brands inflate thread count is by using multi-ply threads and counting each strand of yarn as separate threads. Multi-ply yarn features smaller, not as durable, threads, and doesn’t last as long as more durable single-ply or two-ply threads.

To get counts in the 600, 800, or 1,000 range bedding brands will use two-ply or multi-ply threads, weave them into a theoretical 300 or 400 TC sheet, multiply it by the number of yarns per strand, and sell their sheets that way. Meaning, a 300 TC two-ply sheet is often marketed as a 600 TC.

1,000 TC sheets would have to have 500 threads weaved vertically, and 500 threads weaved horizontally. 1,000 individual strands in one square inch of fabric would result in a cumbersome and dense sheet. With that knowledge, it’s safe to assume sheets with counts over 1,000 feature multi-ply yarn; so though it has a high thread count, the quality of the threads is questionable.

Another way to fluff the thread count is to use lower quality fabrics with thinner threads. Good fabrics will have thicker, stronger strands that are more resistant to wear and tear. When a material has thicker strands, less of those strands are able to fit in one square inch, resulting in a lower number. However, thicker strands are better in regards to durability than thinner strands. For the most part, you’re always better off choosing a high-quality fabric with a low TC rather than something with a higher count.

Why is Ply Important?

Ply indicates the number of yarns in each singular thread, and looking at the ply of the threads is often a better indicator of the durability of the fabric than the thread count. One-ply threads only have one strand of yarn per thread, while two-ply threads have two strands of yarn per thread. If threads are labeled as “multi-ply,” they contain more than two strands of yarns per thread and are likely of poor quality. When choosing sheets, make sure the threads are one or two-ply to get the best quality fabric.

What is the Best Thread Count for Sheets?

Even though it’s been long-thought that sheets with higher thread counts are the best to buy, many sleep specialists agree the best sheets have a count between 300-500. At Sleep Junkie, we recommend finding a sheet set with a thread count between 300 and 400.

However, if you’re somebody who prefers a cozier, thicker sheet, you certainly can find something of high-quality between the 400 and 500 TC mark. You should be raising an eyebrow at sheets with a thread count over 500.

While many people assume that a higher thread count means better quality sheets, this isn’t always the case. In fact, the quality of the thread itself plays a more significant role than the thread counts alone. For most fabrics, an optimal thread count falls between 200-600.

Many sleep specialists agree the best sheets have a count between 300-500. At Sleep Junkie, we recommend finding a sheet set with a thread count between 300 and 400.

When thread counts exceed 800-1000, the difference in softness may be minimal despite the higher cost. Additionally, thicker or heavier fabrics with high thread counts can become less breathable.

Below, we provide a quick reference guide for the ideal thread counts of various fabrics. Keep in mind that some materials are better measured by weight, such as momme or GSM, rather than thread count.

Thread Count Reference Guide by Fabric Type

*In the case of linen, it’s often best to disregard thread count entirely. Linen fibers are naturally heavier, so lower thread counts may result in softer, more breathable sheets.

Materials Measured by Weight

Certain fabrics are not evaluated by thread count but by weight, using measurements like momme or GSM:

Silk: Measured in momme, which assesses the weight of silk. The ideal range for silk sheets is 17-22 momme.

Microfiber: Measured in grams per square meter (GSM). Look for microfiber sheets with a GSM between 90-120.

Flannel: Also measured in GSM. For durable, heavyweight flannel sheets, aim for a GSM of 170 or higher. Lighter flannel sheets offer more breathability but may be less durable.

Jersey: Jersey fabric, often made from cotton, is knitted rather than woven, and its weight can vary depending on the material. Most jersey cotton sheets are around 150 GSM.

Remember, thread count isn’t the sole indicator of quality. The quality of the yarn, the production process, the weave type, and several other factors all contribute to how well a set of bed sheets will perform.

Is a Higher Thread Count Really Better?

What is the highest thread count for sheets?  Thread count alone doesn’t determine a fabric’s breathability, comfort, or softness. For instance, a 400 thread count sheet can be softer and more breathable than one with a 1,000-thread count.

Take, for example, a sheet made from 100% bamboo fiber, which is significantly softer and more slippery than a 100% cotton sheet, even if both have the same thread count. This highlights the fact that thread count alone cannot define a sheet’s characteristics.

The breathability of a sheet depends largely on the material it’s made from. A cotton sheet, for instance, is likely to be more breathable than a polyester one, even if both have the same thread count. Similarly, softness and comfort are influenced by the type of yarn used.

Some brands use thread count as a marketing tool, cramming in as many threads as possible to boost the number.

However, these threads are often short and stubbly, clogging up the fabric without adding value. The shorter threads used in higher thread count sheets are prone to pilling and don’t feel as soft when you run your hand over the fabric.

On the other hand, Egyptian cotton is renowned as the pinnacle of quality bed linen material. It uses longer threads, so fewer threads are needed to keep the fabric together, resulting in a smoother, more luxurious feel.

Sheets with higher thread counts are generally more expensive and are often marketed as higher quality.

While a higher thread count can indicate better quality, it’s not a guarantee. A sheet set with a 400 thread count will usually feel better than one with a 200 thread count, assuming the quality of the yarns, craftsmanship, and weave are similar.

When shopping for sheets, look for a reasonable thread count—typically between 200-600 for most styles. Your expectations should also be adjusted based on the material.

Excessively high thread counts (600-800) often won’t offer much improvement beyond a higher price tag. Very high thread counts can sometimes hinder airflow, resulting in a heavier, warmer feel.

Shoppers should be cautious of thread counts that exceed 900, as this often signals low-quality sheets. Manufacturers may use tricks to inflate the thread count, such as using double- or triple-ply threads, which are typically of lower quality.

Each of these threads is counted multiple times, which can lead to a sheet set with a thread count of 900 that is actually of lower quality than a similar set with a thread count of just 300.

How Do You Judge the Quality of Sheets?

Beyond thread count, there are several ways to judge the quality of a set of sheets. For starters, the most important thing you should look at is the material of the sheet itself. Are you buying cotton or a set with synthetic fibers? Cotton is regarded as the best fabric for sheets because it’s breathable and long-lasting.

In addition to the material of the fabric, look at how your sheet has been treated. Many bedding brands use chemical-based polishes or waxes to give their sheets a shine. Though the sheets look nice at first, after a few washes, your sheets are often left looking worn and old.

A good set of sheets will look better and feel softer with every wash, not do the opposite. To ensure your sheets will look pristine for years, choose a set that hasn’t been chemically treated. Plus, choosing all-natural or organic sheets that are free of chemicals are better for your health.

Lastly, as we mentioned before, always check the ply of the threads. Multi-ply yarns should be avoided, as one-ply and two-ply yarns are almost always the better choice.

Who is Suited for High Thread Count Sheets?

Before we dive into this section, it’s important to clarify that when we use the term “high thread count,” we are referring to sheets in the 400 and 500 range. Though sheets with counts over 1,000 are typically regarded as having the highest TC, they’re the most questionable. To find a quality, high thread count sheet, choose something between the 400 to 500 TC range.

High count sheets, as we stated earlier in our article, feel heavier and usually, cozier, than sheets with a lower count. The more strands in one square inch, the less breathable and airy it feels. High thread count sheets are best suited for people who live in colder climates or struggle to stay warm at night. Because more often than not, people report waking up hot in the middle of the night rather than cold, we expect most people are better off with more breathable sheets.

In the next section, we’ll touch on our recommended top-quality sheet that’s fitting for the majority of sleepers, as well as our recommended high-thread count sheet for those who need a thicker, warmer sheet.

When Does Thread Count Really Matter?

Before you dismiss high thread count bed sheets entirely, consider this important exception: a high thread count can indicate better quality when the sheets are made from 100% cotton with single-ply weaves.

In such cases, higher thread count cotton sheets use smoother and finer yarns, resulting in a softer and more luxurious feel. Conversely, cheap cotton sheets with a high thread count may irritate sensitive skin, as they can be itchy and restrict air movement, leading to discomfort.

When Does Thread Count Indicate Quality?

In an ideal scenario where all bedding is made with single-ply threads, thread count can be a reliable indicator of overall quality and comfort. This is particularly true when the fibers undergo a process called carding, which is essential in cotton manufacturing.

Carding removes short and low-quality fibers, leaving only the longer, more durable fibers behind. When these long fibers are spun, they create a stronger and more reliable material.

But what thread count should you be looking for? And what thread count is considered luxurious?

For “basic quality” linen bedding, you’ll typically find a thread count between 132 and 144. “Good quality” linen bedding will have a thread count ranging from 180 to 220.

As you move up the scale, “great quality” linen will feature a thread count above 300, while “excellent quality” linen surpasses 400. At the very top end of the spectrum, the most luxurious linen bedding boasts a thread count exceeding 500.

To help you determine when a higher thread count might be necessary, we’ve outlined which rooms in your home are best suited for different levels of bedding quality, from your master bedroom suite to the guest room you rarely use.

Understanding these distinctions can help you choose the right bedding for each room in your home, ensuring that you balance comfort and quality according to your needs.

Amerisleep Cotton Sheet

At Sleep Junkie, we believe the best sheets you can buy for the majority of sleepers are Amerisleep’s Cotton Sheet Set. We’re fans of this sheet set because it’s 100% combed Upland cotton and 310 TC. Combed cotton is usually longer-lasting than cotton that is uncombed because the combing process helps pull all the shorter, flimsier strands from the fabric— leaving a weave of long, durable threads. Amerisleep’s sheet set also features a low-wrinkle design, which makes their sheets easier to wash and maintain. A concern with cotton bedsheets are their tendency to wrinkle, so Amerisleep’s low-wrinkle technology is a major bonus for people who are bothered by a messy bed.

These sheets have a percale weave, so they feel crisp and cool to the touch. Plus, because they have a count of 310, they should be airy, allowing for hot air to escape out of the bedding. Amerisleep’s sheets are compatible with mattresses up to 18 inches thick, meaning they should fit just about any bed. A Queen set of Amerisleep’s top-rated sheets is $140, and as a bonus, they’re backed by a 5-year warranty.

Top Things to Consider When Buying Bed Sheets

Investing in high-quality bedding is crucial not only for the aesthetic and tactile appeal but also for improving your overall sleep health. The top three factors to consider when purchasing bed sheets are:

1. Fabric Quality

Cotton, for example, is a natural fiber that allows the fabric to breathe in harmony with your body temperature. However, when cotton is blended with polyester, it significantly alters the fabric’s breathability.

2. Craftsmanship and Style

People often don’t realize the importance of workmanship until they unwrap the bedding at home. There’s nothing more frustrating than a pillowcase with a shallow opening that causes the pillow to slip out or a duvet cover that’s a hassle to fasten due to numerous small buttons or ties.

3. Practical Design

Since you typically change your sheets every few weeks, it’s essential that the design is user-friendly. Another key aspect to look for is the stitch density along the seams. If you can count around five stitches per centimeter, it’s a sign that the bedding was sewn with care.

On the other hand, if there are only two or three stitches per centimeter, it indicates the fabric was rushed through the sewing machine, which can be a clear sign of poor quality.

As you can see, thread count is far from the only factor to consider when buying bed sheets. You don’t need to be an expert to find the perfect sheets for your needs. By understanding what you’re looking for, choosing suitable fabrics, and selecting what feels right, you can easily find your ideal bedding.

Best High Thread Count Sheets

Sleepers who are seeking a high thread count sheet should consider Snowe’s Percale Sheet Set with a 500 thread count. We like this sheet set because it uses high-quality, Italian milled Egyptian cotton. A Queen set of these sheets cost $198.

Like the Amerisleep sheets, Snowe’s Percale Sheet Set has a percale weave, so they feel breathable and smooth. We expect these sheets to be long-lasting and durable because they feature long-staple and extra-long-staple fibers, which are resistant to pilling and hold up longer. These sheets fit mattresses up to 17 inches thick, so they’re compatible with a majority of beds sold.

What Other Factors Influence the Softness of Bedding? 

While it’s clear that good bedding doesn’t need an excessively high thread count, as we’ve discussed, thread count is just one of many factors that contribute to the feel of a sheet.

Generally, high-quality bedding can be made from single-ply cotton with a thread count between 180 to 300. However, several other elements also play a significant role in determining the softness and comfort of your bedding:

a. Grade and Quality of Cotton

The quality of the cotton or fabric used is far more crucial to the feel of the sheet than the thread count alone. While Egyptian cotton sheets often boast a higher thread count than traditional cotton, this isn’t the key to their luxurious feel.

The true luxury comes from the long-staple cotton grown along the banks of the Nile, which provides a silky softness due to its superior fiber quality, not just the tight weave.

The same holds true for materials like Tencel (made from eucalyptus pulp) and bamboo, both of which are exceptionally soft, breathable, antimicrobial, and antibacterial. To achieve maximum softness and durability, it’s best to avoid short-staple cotton.

b. Type and Nature of Fabric Weaving

When comparing bedding, it’s important to consider the fabric’s weave. High-quality sheets often feature a sateen weave (one yarn under, three yarns over) or a percale pattern (one yarn under, one yarn over), resulting in a crisp, comfortable finish for a good night’s sleep.

For the ultimate in luxury, seek out bedding woven by manufacturers known for their unparalleled standards and expertise.

c. Manufacturing and Finishing Process

Whenever possible, opt for organic bedding from a sustainable manufacturer committed to producing environmentally friendly products.

The alternative could mean sleeping on sheets treated with harmful chemicals like carbon disulfide and caustic soda, which are toxic and pose a risk to your health.

For example, Eucalyptus silk is produced using 95% less water than traditional cotton production, with all trees grown in non-farmable, biodiverse forests, and all production waste is repurposed at another stage.

d. Sewing Quality

Selecting top-quality fabric is only the first step; ensuring that your bedding is expertly woven and sewn is equally important for enhancing comfort.

A well-sewn sheet can make a noticeable difference in how it feels. A good rule of thumb is to look for bedding with at least five stitches per centimeter, indicating that it was crafted with care rather than rushed through a machine.

e. Quality of Dyes and Pigments

Many manufacturers use toxic bleaches and dyes to color their bedding, which can be harmful to both you and the environment.

Additionally, these harmful chemicals can negatively impact your comfort as you sleep, potentially causing or worsening skin issues. Choosing bedding dyed with safe, non-toxic pigments is essential for both your health and the overall comfort of your sleep experience.

Frequently Asked Questions:

To wrap up this article, we’ve addressed some of the most common questions our customers ask about thread count, providing further insights into what these numbers really signify.

How is Thread Count Calculated?

Thread count is determined by adding the number of vertical and horizontal threads within each square inch of fabric. For example, if a fabric has 150 horizontal threads and 150 vertical threads, its thread count would be 300.

What is the Maximum Thread Count?

Some manufacturers may advertise thread counts of 1,000 or more, but this doesn’t necessarily mean the sheets are of higher quality than a single-ply 500 thread count sheet.

Be cautious with bedding that claims an exceptionally high thread count, as it’s often made using multi-ply threads, which can actually indicate lower quality.

What is the Best Thread Count for Staying Cool?

Surprisingly, staying cool at night isn’t directly related to thread count. The type of material you choose plays a much bigger role in keeping you cool.

Bamboo, linen, and lightweight cotton blends are particularly effective for maintaining a cool temperature during hot nights. Look for breathable, moisture-wicking sheets to ensure a comfortable sleep, even during a heatwave.

Are 1,000 Thread Count Sheets Worth It?

A high thread count doesn’t always equate to better quality or softness. In fact, thread count has little to do with a fabric’s breathability, comfort, or softness. A 400 thread count sheet might be softer and more breathable than one with a thread count of 1,000.
