Why Do Bed Sheet Sizes Matter?
If you have a thick foam mattress topper or use a pillow-top mattress, finding the right bedding size is frustrating. The label of a fitted sheet says it should fit your bed, but it barely hugs the corners of the mattress.
Locating the right sheet size and pocket depth (the depth of a fitted sheet, or the mattress thickness it will cover) will solve that problem.
We wanted to help simplify things a bit, so we created this bed sheet size guide. It lists every sheet size and option available in the U.S., along with the proper mattress size each one should be used with.
Take a look and find out the perfect size sheets for your bed, from cribs and dorm beds to the extra-large California King!
Standard Bed Sheet Sizes
From the smallest to the biggest mattresses available, these are the dimensions of standard bed sheet sizes you’ll come across along with the size mattress they are designed to fit. We’ve also included dimensions for other bedding items that are sized to fit, like comforters and pillowcases.
Crib, Cradle, Bassinet, or Toddler
Crib mattresses are the same size as toddler mattresses. Because they’re small and of a uniform thickness, most crib-fitted sheets don’t include a depth measurement. On average, crib mattresses are 5″ to 6″ deep.
Twin beds, the next size up from a crib mattress, use twin size sheets and typically require a standard or deep pocket sheet.
Twin XL, Extra Long, or Split King
Twin XL beds are the same width as a twin, but as an XL, they are 5″ longer. These will not fit a twin XL bed – only twin XL sheets will. Twin XLs are commonly used on dorm room beds.
Full, Standard, or Double
A full-size bed is the same length as a standard twin bed, but they can’t use the same size sheets because it is much wider.
Full XL, Extra Long
A full XL bed is the same width as a standard full, but they can’t use the same sheets because it is 5″ longer.
A queen bed is considerably larger than a standard full – 6 inches wider and 5 inches longer. Because they’re so much wider, queen beds usually use queen size pillows and pillowcases.
RV Queen, Short Queen
Designed for RVs and campers short on space, the RV queen is 5 inches shorter than a standard queen, but the same width.
California queen beds are notoriously tough to find sheets for because they are 4″ longer than the standard queen size.
A king bed, one of the largest sizes, usually requires a fitted sheet with deep to extra deep pockets.
The largest standard bed size in the U.S., the California king is 4″ longer than a standard king. It needs a fitted sheet with extra deep pockets.
RV King, Short King
The shorter version of a standard king bed, the RV king, will typically be thinner than a regular mattress and needs a fitted sheet with standard to deep pockets.
Fitted Sheet Sizes and Depths
The other measurement included for fitted sheet size is depth. Because mattresses are made in standard sizes but vary in thickness, fitted sheets use a measurement that flat sheets don’t.
It’s called “pocket depth,” and it ensures a snug fit with mattresses that have standard, deep, and extra deep thickness.
Keep in mind that beds with mattress toppers and pillow-tops will likely need a deep pocket or extra deep pocket fitted sheets.
Fitted Sheet Pocket Depths:
Hard-to-Find Sheet Sizes
It’s difficult to find bed sheet sets that aren’t one of the standard sizes (like Twin XL, Full XL, and RV queen and king), so knowing these measurements is essential.
In a pinch, you can swap sheets with the next standard size up to get a decent, but not perfect, fit. While a top sheet or comforter that is slightly too large won’t be noticed much, fitted sheets that don’t fit snugly won’t be comfortable to sleep on.
Finally, for antique beds and others that may not fit the standard sheet size chart, custom-sized sheets ordered using the exact measurements of your mattress can be a good, if slightly costly, solution.
