Standard Sizes

Pillow cases are available in a wide range of sizes. The most common pillow case size is the standard size, which measures 20 inches by 26 inches. However, there are also other sizes available, such as the king size, which measures 20 inches by 36 inches.

Standard pillowcase size

A standard pillowcase is sized to fit a standard pillow, which is 20 inches wide by 26 inches long. A queen-size pillowcase is larger, at 20 inches by 30 inches, while a king-size pillowcase is the largest of the three, measuring 20 inches by 36 inches.

King size pillowcase size

A king size pillowcase is 21 inches x 37 inches.


King size pillow cases are usually made out of cotton. Most king pillow cases are 20 inches by 36 inches, but there can be some variation in size. Some pillow cases are made out of other materials such as silk or satin.


Cotton is a natural fiber and is used in a variety of fabric types including linen and canvas. It’s been around for ages and is known for being a durable, comfortable, and breathable fabric. Cotton pillowcases are available in a variety of thread counts which indicates the number of fibers per square inch of fabric. The higher the thread count, the higher the quality of the fabric.


Silk is a natural protein fiber, some forms of which can be woven into textiles. The protein fiber of silk is composed mainly of fibroin and is produced by certain insect larvae to form cocoons. The best-known type of silk is obtained from the cocoons of the larvae of the mulberry silkworm Bombyx mori reared in captivity (sericulture). The shimmering appearance of silk is due to the triangular prism-like structure of the silk fiber, which allows silks to refract incoming light at different angles, producing different colors.


King-size pillow cases are usually made out of linen. Linen is a durable fabric that can last for a long time. It is also a breathable fabric, which makes it ideal for use in a pillow case. Pillow cases made out of linen are usually more expensive than those made out of other fabrics, but they are worth the investment because they will last longer.

Thread Count

A pillowcase’sthread count is the number of threads per square inch of fabric. The higher the thread count, the more densely woven the fabric and the softer it will feel. A pillowcase with a higher thread count will also be more durable and less likely to pill.

Low thread count

Thread count is the number of threads per square inch of fabric. The higher the thread count, the softer and more durable the fabric will be. A low thread count (<180) will result in a rougher fabric that is less durable and more likely to pill.

High thread count

The term “thread count” refers to the number of horizontal and vertical threads per square inch of fabric. It is commonly used in the marketing of bed linens and fabrics. A higher thread count usually means a softer and more durable fabric.

Thread count is determined by counting the number of threads in one square inch of fabric. The resulting number is then divided by 2 to account for both the vertical and horizontal threads. For example, if there are 100 threads in one square inch of fabric, the thread count would be 50.

Most fabrics have a thread count of between 200 and 800. High thread count fabrics typically have a thread count of 800 or more. These fabrics are often considered to be luxury bedding because they are so soft and durable.

If you’re looking for high quality bedding, look for a high thread count. However, keep in mind that a higher thread count does not necessarily mean better quality. There are other factors to consider, such as the type of fabric and the weave.


A king size pillowcase is a decorative item for a bed. It is usually made of a strong fabric such as cotton or linen. The size of a king size pillowcase varies depending on the size of the pillow it is intended to cover. A pillowcase that is too small will not be able to stay in place and may cause the pillow to become misshapen. One that is too large will be bulky and difficult to store.


Plain pillowcases are the most basic type of pillowcase – they are simply a piece of fabric with an opening for the pillow. They may have a seam down the middle, or they may be one continuous piece of fabric. Plain pillowcases are typically made from cotton or polyester, although other fabrics may be used as well.


Pillow cases are usually sold in two sizes: Standard and King. A Standard pillow case will fit a pillow that is 20 inches by 26 inches, while a King pillow case will fit a pillow that is 20 inches by 36 inches. There are also a few other size options available, such as Queen and Euro, but these are less common.

When it comes to patterned pillow cases, there is no real standard size. The size of the pattern on the pillow case will depend on the design of the case itself. Some patterned pillow cases may have a larger design that takes up more of the fabric, while others may have a smaller design that is more subtle. It really just depends on the style of the case and what you are looking for in a design.


Choosing a pillow case for your king size pillow should be based on both comfort and style. The size of a king size pillow is 20″ x 36″, which is generally a bit larger than a standard pillow. A standard pillow case is usually about 20″ x 26″. A king size pillow case should be at least 20″ x 36″, but can be larger.


White is the traditional color of pillow cases and sheets. It is a popular choice because it is neutral and goes with any decor. White pillowcases are often made of cotton or linen, which are natural fibers that breathe and are comfortable to sleep on.


Pillow cases come in a variety of colors, but the most popular color is cream. Cream pillow cases are versatile and can be used in a variety of settings, from formal to casual. They are also neutral enough to match most bedding sets.


Blue pillow cases are typically square or rectangular in shape and measure 20 inches by 30 inches. They are made of a variety of materials including cotton, polyester, and satin.
