If you’re shopping for new bedding, the right bed sheet sizes are crucial. Whether you have a twin-size or full bed, a queen bed, a king, or a California king, it’s important to understand the dimensions of various sheet sizes to ensure a perfect fit. Our bed sheet sizes and dimensions guide is here to help you navigate the vast assortment of sizes and dimensions, so you can select the perfect option for your sleeping space. Once you discover the appropriate sheet size for your bed, you’ll experience a more beautiful bedroom and a great night’s sleep.

Common Bed Sizes and Corresponding Bed Sheet Sizes Chart

You might wonder things like, what size are queen sheets? Most manufacturers measure their bed sheet sizes in inches which is based on the actual mattress dimensions. Here is a comprehensive list of standard bed sheet dimensions based on mattress size. The numbers on the list below reflect the length and width of each bed size based on how many inches wide and inches long they are:

sheet sizes Bed sheet dimensions
  • Twin mattress: 38 x 74
  • Twin XL mattress: 38 x 80
  • Full mattress: 54 x 75
  • Queen mattress: 60 x 80
  • King mattress: 76 x 80
  • California King mattress: 72 x 84

Keep in mind that these are standard mattress sheet sizes, but they may vary slightly based on a few different factors like the brand or manufacturer and other considerations. A twin XL mattress is about six inches longer than a standard twin size bed. The full sheet size (or mattress size) is much wider than a twin and twin XL, yet slightly shorter than a Twin XL. Queen beds are 80 inches long like a twin XL and a king, but they’re also about four inches narrower than a king-sized bed. King beds are approximately four inches wider than a California king, but also about four inches shorter. That’s why it’s so important to find the right bed sheet size based on the actual dimensions of the bed itself.

Understanding Depth and Pocket Sizes

Other than the basic mattress size, it’s important to understand the concept of mattress depth and how it works when choosing fitted sheet sizes with the appropriate pocket size. Look at the thickness of your mattress to determine whether you’ll need fitted sheet sizes with a deeper pocket depth. If you use a mattress topper, this will also increase the thickness. The thicker the mattress, the larger the fitted sheet pocket depth required, which is more than the standard seven to 12 inches thick. Choosing the appropriate depth and pocket size will prevent your fitted sheet from sliding and popping off in the middle of the night. To measure your mattress depth accurately, start by removing the fitted sheet. Using a ruler or tape measure, determine how thick the mattress is from top to bottom, but make sure you don’t include the box spring. A deep pocket sheet fits a 13-to-17-inch mattress, while those with extra-deep pockets will fit an 18- to 25-inch-thick mattress.

Fitted sheets sizes

Fitted Sheets and Their Sizes

When looking at bedding sizes, it’s vital to make sure that you choose the correct size for the fitted sheet so that it stays in place. Full size sheet dimensions are similar to the length of twin fitted sheets, but they’re much wider, for example. Fitted sheets have elastic at the corners or on the ends to help keep them in place. The goal is to ensure that your fitted sheets have a nice, snug fit on the mattress, so they don’t slip or shift when you move around so you can sleep comfortably. Here are some common sheet measurements for fitted bed sheets:

  • Twin fitted sheet: 39-40 x 75-76
  • Twin XL fitted sheet: 39-40 x 80
  • Full fitted sheet: 54-55 x 76
  • Queen fitted sheet: 62 x 82
  • King fitted sheet: 78 x 82
  • California king fitted sheet: 73 x 84-85

Choosing the appropriately sized fitted sheet is absolutely crucial to ensure that your bedding fits the way it should. For example, queen sheet dimensions will be much larger than those of a twin or full-size bed. A California king sheet size is narrower than standard king sheet dimensions, but it’s also much longer. If you notice a product listed with a double bed sheet size, it’s referring to a full-size bed.

Keep these measurements in mind so that you can be absolutely sure you’re selecting the right sheet size in inches based on your specific bed and mattress size. This will keep your beautiful new sheets securely in place so you can enjoy a restful slumber.

Flat Sheets and Their Dimensions

Flat sheets also come in various sizes based on the mattress and bed size. A flat sheet lies on top of the fitted sheet and adds another layer of warmth and softness underneath comforters, blankets, quilts, or duvet covers. Many people like to use a flat sheet between the top layer of bedding to keep it cleaner for longer, too. Here are some common flat sheet sizes and bed sheet dimensions for these types of bed sheets. Note that while a typical queen bed uses a 90 x 102 sheet size for a flat sheet, the dimensions can vary based on the brand and other factors, and this applies to each of the bed sizes below.

  • Twin flat sheet dimensions: 60-75 x 90-102
  • Twin XL flat sheet dimensions: 60-75 x 102-114
  • Full flat sheet dimensions: 84-90 x 90-96
  • Queen flat sheet dimensions: 92-102 x 88-115
  • King flat sheet dimensions: 102-110 x 88-115
  • California flat sheet dimensions: 108-111 x 102-114

Pillowcase Sizes for Different Pillow Types

Aside from these standard sizes of bed sheets, it’s also important to choose the appropriate matching pillowcase size to coordinate with the pillows you use. Not all pillows are the same. Some pillow styles are longer and larger than others, so it’s vital to select the appropriate size based on what you have. Usually, a twin, twin XL, and full-sized bed sheet set come with standard pillowcases while a queen size bed has pillowcases that are slightly bigger. King and California king beds’ pillowcases are larger than queen size, and you may also use a body pillow separately, which requires a bigger pillowcase, too.

  • Standard size: 20 x 26 inches
  • Queen size: 20 x 30 inches
  • King/California king size: 20 x 36 inches
  • Body pillow size: 20 x 54 inches

You might also want to add decorative pillows or a lumbar pillow to your bed. A Euro sham (or Euro-style pillowcase) typically measures 25 x 25 inches, a lumbar or roll pillowcase usually measures 6.5 x 13 inches, and standard deco pillowcases measure around 16 x 16, 18 x 18, or 20 x 20 inches square.

Split and Adjustable Bed Sizes

There are also some specialized bed sizes, such as split king and adjustable beds that may require different sheet sizes. A standard king size adjustable bed can use standard king size sheets, but you may need different-sized bed sheets if you have a split adjustable bed. These beds usually have two separate mattresses pushed together to form one size, allowing each sleeper to make their own individual adjustments. In this case, you’d need to purchase two sets of twin size sheets, or two sets of whatever corresponding sizes your adjustable bed uses. Look carefully at the fitted and flat sheet dimensions to ensure that they fit your adjustable bed accordingly.

Choosing the Right Sheet Size

Here are some practical tips to help you choose the right bed sheet size and the best possible sheets for your unique needs.

  • The easiest way to identify bed sheet sizes is to know exactly what size mattress you have. Remember that twin xl sheet measurements are longer than a standard set of twin sheets. Queen sheets are the same length as king mattresses and king size sheets, but they’re also much narrower.
  • Know how to measure your mattress for the best accuracy. Remove any existing sheets, then use a tape measure to record the dimensions of your mattress in length and width. Don’t forget to measure the thickness as well to determine whether you’ll need a deep pocket fitted sheet.
  • It’s also important to choose the best bed sheet fabric or material for maximum comfort while you sleep. Select natural fabrics like organic cotton sheets or a set of sheets made of organic linen, which are known for their hypoallergenic, breathable, and moisture-wicking properties.
  • Aside from ensuring you choose the appropriate bed sheet size, don’t forget to look at the dimensions of your bed skirt if you plan to use one. In most cases, the bed skirt will correspond with your mattress size, but confirm this before you buy one unless it comes with the sheet set you purchase.
  • Check to ensure that your duvet cover has the correct dimensions so that it matches the duvet insert size correctly.
  • If you’re ever in doubt, refer to our bed sheet sizes chart and list to help you find the right fitted sheet, flat sheet, and pillowcase size for your particular sleeping space.
  • Not only does selecting the right sheet size keep everything in place but it may also help to prevent pilling and excess wear and tear over time.
