Standard King Size

A king size sheet is a bed linen with dimensions of 76 inches by 80 inches. It is the largest size available for a fitted sheet. A king size flat sheet is 104 inches by 108 inches. A king size comforter is usually 106 inches by 92 inches.


A king size bed is approximately 76 inches wide and 80 inches long. A king size mattress is slightly larger than a queen size mattress, which measures 60 inches wide by 80 inches long. A twin size mattress, the smallest standard mattress size, is 38 inches wide by 74 inches long.

Fits mattresses

King size sheets are great for larger mattresses, like the California king. They’re also perfect if you have a king-size bed and need more coverage than what a standard queen size can provide. But what exactly are king size sheets and how do they differ from other types of bedding?

King size sheets are designed to fit mattresses that are 76 inches wide by 80 inches long. They’re also known as “Eastern king sheets” because this is the most common mattress size in the eastern United States. In addition to being longer than a standard queen size mattress, a king size mattress is also wider. This means that you need sheet sets that are specifically designed for this mattress size in order to get a proper fit.

King size sheet sets usually include a fitted sheet, a flat sheet, and two pillowcases. The fitted sheet is designed to fit snugly around your mattress, while the flat sheet drapes over the top of your bed. The pillowcases included in most king size sheet sets will fit standard-size pillows.

If you have a king-size bed, it’s important to make sure you have the right bedding to match. With king size sheets, you can get the perfect fit for your mattress, ensuring a comfortable night’s sleep.

California King Size

A California king size bed is also known as a “Western king” is 72 inches wide by 84 inches long. This is the longest bed size available in the market and is best for couples who love their sleep. Sheets for this size of bed need to be specially made to accommodate its size. When purchasing a fitted sheet, make sure to check the dimensions carefully so you don’t end up with a sheet that’s too small or too large for your bed.


A California king size bed is 72 inches wide and 84 inches long. It is slightly narrower and longer than a standard king size bed, which is 76 inches wide and 80 inches long. A California king size bed is a good choice for tall people or couples who want more space to spread out.

Fits mattresses

The California King is the largest of all the king size mattresses, measuring 72” wide by 84” long. That’s 6” wider and 4” longer than a standard king size mattress. It’s also known as a “western king” or an “off-king.”

A California King is a great choice for tall people or couples who want more width than a standard king mattress offers. It’s also a good option if you have limited space in your bedroom, since it’s 4” narrower than a standard king. But because it’s 84” long, it will still fit most standard sheets and comforters.

If you need more sleeping surface than a California King can provide, you can opt for an “Olympic Queen,” which is 66” wide by 80” long, or a “California Queen,” which is 60″ wide by 84″ long.

Split King Size

A split king size bed is also known as a dual king size bed. It is two twin extra-long beds pushed together side by side. A split king size bed is perfect for couples who want separate beds but don’t want to sleep in two twin beds. The two beds can be adjusted separately so each person can have the perfect sleeping position.


A standard king size bed mattress is 76 inches wide by 80 inches long, making it approximately 16 inches wider than a queen bed. A king size mattress is a great option for couples who want plenty of space to move around, as well as for singles who want plenty of room to sprawl out.

King size sheets are available in a variety of materials, including cotton, flannel, and microfiber. You can also find sheets specifically designed for adjustable beds. When shopping for sheets, keep in mind that you’ll need a fitted sheet that is 78 inches long by 80 inches wide, as well as a flat sheet that is 108 inches long by 102 inches wide.

Fits mattresses

Most king size mattresses measure around 76 inches wide by 80 inches long, but there is some variation. That’s why it’s important to measure your mattress before you buy a king size sheet.

To find the right fit, look for sheets that are labeled “split king.” These sheets are designed specifically for mattresses that are split in the middle, so they will fit even the largest king size mattress.

If you have a traditional king size mattress, you can also look for “king size” or “oversized” sheets. These sheets will typically be big enough to fit your mattress, but they may not always stay in place as well as split king sheets.

No matter what type of king size mattress you have, it’s important to make sure that your sheets fit snugly and don’t slip off during the night. If your sheets are too loose, they can bunch up and be uncomfortable. If they’re too tight, they can be difficult to put on and take off.

The best way to find the perfect fit is to measure your mattress and then compare those measurements to the size of the sheet you’re considering. Most manufacturers include sizing information on their websites or on the packaging of their products.
