Mattress Thickness
When choosing the perfect set of sheets for your bed, knowing how tall your mattress is will help you determine the proper height/depth dimension. While standard mattresses range from 10-12”, there are five mattress depths you are most likely to encounter. Sleepfoundation.org defines these as:
1. Extra Thick/Deep: 14" or more
2. Thick or Deep Pocket: 12"-14"
3. Standard: 10"-12"
4. Slim: 8"-10"
5. Low Profile: 8" or less
Mattresses are comprised of multiple layers; there is often a comfort layer on the top that is 2"-3" thick, a base layer that is 6"-8" thick, and a transition layer that is 1"-2" thick. Together, these layers make up the height or depth of your mattress.
Choosing the Right Sheets for Your Mattress Size & Thickness
Choosing the right sheets starts with understanding your mattress dimensions and thickness. By knowing these key details, you can ensure a snug fit, optimal comfort, and a polished look for your bed. Whether it’s a deep-pocket sheet for a thicker mattress or a standard fit for a more traditional size, the right sheets make all the difference in your sleep experience. Take the time to measure and match, and you’ll enjoy restful nights on a comfortable and luxurious-feeling bed.
