If you’re shopping for new bedding, selecting the right bed sheet size is 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 bed sheet sizes to ensure a perfect fit. Our bed sheet sizes and dimensions guide is here to help you navigate the different sheet bed sizes and dimensions, so you can select the perfect option for your sleeping space. Once you have the appropriate sheet size, you’ll experience a more beautiful bedroom and a great night’s sleep.

Common Bed Sizes and Corresponding Sheet Dimensions

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 sizes and dimensions reflecting the length and width based on how many inches wide and inches long for each corresponding bed size:

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 bed 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. 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 sheets that have the appropriate pocket size. Look at the thickness of your mattress to determine whether you’ll need a fitted sheet with a deeper pocket depth. If you use a mattress topper, this will also increase the thickness, so you’ll probably need a larger fitted sheet pocket depth 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. To measure your mattress depth accurately, start by removing the fitted sheet. Then, using a ruler or tape measure, determine how thick the mattress is from top to bottom, and 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 buying bed sheets, it’s vital to make sure that you choose the correct size for the fitted sheet so that it stays in place. These 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 sizes and dimensions 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

The appropriately sized fitted sheet is absolutely crucial to making sure that your bedding fits the way it should. Keep these measurements in mind so that you can be absolutely sure you’re selecting the right dimensions based on your 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. 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 size and bed sheet dimensions for flat bed sheets.

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

Pillowcase Sizes for Different Pillow Types

Aside from these standard bed sheet sizes in inches, it’s also important to choose the appropriate matching pillowcase size that coordinates with the pillows you use. Not all pillows are the same, and some 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 may also choose 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 sheets 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. Select natural fabrics like organic cotton sheets or a set of sheets made of organic linen. Both of these 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 bed skirts if you plan to use them. Most of the time, the bed skirt will correspond with your mattress size, but it’s best to confirm before you buy one unless it comes with the sheet set you purchase.
  • If you’re using a duvet cover, check to confirm that it has the right dimensions to match 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.
