What Thread Count Means and What Constitutes a Good Thread Count

Thread count is often used as a measure of sheet quality, but it doesn't always indicate high quality. Thread count refers to the number of threads per square inch of fabric, and it can range from 200 to 800 or higher. Other factors to consider when buying sheets include ply, fiber length, and weave pattern. Different materials have different ideal thread counts, such as 300-600 for sateen cotton sheets and 400+ for silk sheets.

When buying new sheets, what figure do you look at to gauge their quality? For most people, it’s thread count. Higher thread count in bedding has been associated with luxury for a long time.

However, a high thread count doesn’t always correlate to a high-quality set of sheets.

Let’s explore what thread count means, the ideal thread counts for different fabrics, and other considerations to make when buying a new set of bed sheets.

What are thread counts on sheets?

Thread count refers to the number of threads woven per one square inch of fabric. The thread count includes both horizontal (weft) and vertical (warp) threads.

For instance, if one inch of fabric has 150 vertical threads and 150 horizontal threads, the thread count number is 300. Thread count figures can range anywhere from 200 to 800 and even higher.

Though many people think a high thread count means a bed sheet set is made with high-quality fabrics, that’s not always true. Let’s take a look at the importance of thread count in your bed sheets.

Does thread count matter for your bed sheets?

Many people believe a higher thread count always means the softest set of sheets. While this is true to a degree, it’s not the only thing that matters.

First of all, it’s important to note that thread count is only really relevant for cotton bedding. For cotton sheets, thread count can range anywhere from 200 to 1,000.

The problem is, you can only get so many threads onto the loom—and in order to increase thread quantity, some manufacturers sacrifice thread quality.

When it comes to other materials, like silk or linen, thread count isn’t an indicator of quality.

Silk sheets are spun with a much thinner thread, so they generally have higher thread counts, while linen sheets are spun with thicker thread, giving them a lower thread count.

Ideal thread counts for each bed sheet material

Now that we know high thread count sheets aren’t always high-quality, let’s go over the best thread count for each type of bed sheet material.

Sheet MaterialBest Thread Count
Sateen Cotton Sheets

300 to 600 threads per square inch

Percale Cotton Sheets

200 to 400 threads per square inch

Silk Sheets

400+ threads per square inch

Linen Sheets

80 to 120 threads per square inch

Microfiber Sheets

Measured in grams per square meter (GSM). Look for microfiber sheets with a GSM of 90 to 120.

Other factors to consider when buying a new set of sheets

Even though it’s important, thread count isn’t the only factor you need to consider before purchasing a higher-quality bed sheet set. You should also take the ply, fiber length, and weave pattern of your sheets into consideration before finalizing your purchase.


Ply refers to the number of fibers twisted together into a single thread. When it comes to ply, less is definitely better. Two-ply or other multi-ply yarns create fabrics that are coarser, heavier, and most importantly, less durable. Lower-quality sheets are usually made with three-ply or four-ply yarns.

If you’re looking for something soft and light, it’s best to opt for bed sheets made with single-ply yarn.

Fiber length

Staple refers to the length of the cotton fiber. There are two main types of cotton: short-staple and long-staple.

Short-staple cotton is made with shorter fibers, making the fabric less durable and prone to damage like fraying or wrinkling.

Long-staple cotton, on the other hand, is made with longer fibers to make a smoother, stronger, and more durable fabric. Both Pima and Egyptian cotton are great examples of long-staple cotton.


Weave is another factor you’ll encounter when choosing sheets. Weave isn’t an indicator of quality, but it’s worth paying attention to since different types of weave create fabrics with slightly different properties. Generally, you’ll find sheets with either a percale weave or a sateen weave.

A percale weave (also known as a plain weave) tends to be crisper, lighter, and more breathable. It’s great for hot sleepers.

A sateen weave usually feels silkier and heavier. It’s great for people who tend to sleep cold.

Frequently asked questions

Is thread count the most important factor in choosing sheets?

While thread count is important for cotton sheets, it isn’t all that important for other bed sheet materials. Additionally, there are other factors you should consider like weave, fiber length, and ply.

Are sheets with a higher thread count always high-quality sheets?

No, sheets with a high thread count aren’t always high-quality. Ideal thread count is dependent on the fabric used to make the bed sheets.

Does a higher thread count mean softer sheets?

When it comes to cotton sheets, a higher thread count can mean a softer fabric. However, thread count doesn’t equate to softer sheets for silk and linen fabrics.
