Designed to provide a comfortable and secure covering, deep pocket fitted sheets fit snugly over thicker mattresses, ensuring you never wake up to find your sheets unraveling. With the growing popularity of luxury bedding and plush mattresses, deep pocket sheets have become a bedroom must-have. In this guide, we’ll explore what deep pocket sheets are and highlight the best options for your style and comfort needs in 2025.

What Are Deep Pocket Sheets

Deep pocket sheets refer to fitted sheets designed with extra depth to accommodate thicker mattresses. Unlike standard fitted sheets that typically fit mattresses up to 12 inches thick, deep pocket sheets are made for mattresses with extra height, including those with pillow tops, memory foam layers, or mattress toppers. These sheets feature elasticated corners and reinforced edges to ensure they stay in place all night, no matter how much you toss and turn. Whether you have a luxury mattress or an adjustable bed, deep pocket sheets ensure a smooth and wrinkle-free sleeping surface.

How Many Inches Are Deep Pocket Sheets?

The depth of deep pocket sheets can vary, but they are generally designed to fit mattresses between 14 and 18 inches thick. Some extra-deep pocket sheets go even further, accommodating mattresses up to 22 inches in height. To determine the right size, measure your mattress, including any toppers, from the bottom edge to the highest point. Matching the depth of your sheets to your mattress is crucial for a secure fit and comfortable sleep. If your mattress is thicker than 18 inches, opt for sheets labeled as “extra-deep pockets” for the best results.

FAQ

What is the Difference Between Deep Pocket and Extra Deep Pocket Sheets?

The primary difference between deep pocket and extra deep pocket sheets is the mattress thickness they are designed to fit. Deep pocket sheets are typically made for mattresses with a thickness between 12 and 16 inches, making them suitable for most standard or pillow-top mattresses. 

Extra deep pocket sheets, on the other hand, are designed for thicker mattresses, often accommodating those that are 17 to 22 inches thick. If your mattress has additional layers, such as memory foam toppers or built-in pillow tops, extra deep pocket sheets might be a better choice to ensure a proper fit without slipping or bunching.

Does it Matter If a Fitted Sheet is Too Deep?

Yes, it does matter if a fitted sheet is too deep for your mattress. While a fitted sheet with extra depth can still fit a thinner mattress, it may result in excess fabric, causing the sheet to bunch or wrinkle during use, which can be uncomfortable. Additionally, the elastic edges might not stay securely in place, leading to frequent adjustments. To ensure a smooth and snug fit, it's best to choose fitted sheets that match your mattress thickness as closely as possible.

What Size is a King-deep Pocket Fitted Sheet?

A king-size deep pocket fitted sheet is typically designed to fit mattresses measuring 76 inches wide by 80 inches long. The "deep pocket" designation means the fitted sheet can accommodate mattresses with a depth of 12 to 16 inches, depending on the specific product. For a complete bedding set, the flat sheet size for a king bed is usually 108 inches by 102 inches, providing ample coverage for larger beds. Always check the exact measurements on the product label to ensure compatibility with your mattress.

What Depth-Fitted Sheet Do I Need on a 25cm Mattress?

For a 25cm (10-inch) mattress, you will need a fitted sheet with a depth of at least 30cm (12 inches) to ensure a proper fit. It’s generally recommended to choose a fitted sheet that is 5 to 10cm (2 to 4 inches) deeper than your mattress to account for tuck-in space and any mattress toppers or pads you might use. A 30cm fitted sheet is a standard size and should comfortably fit your 25cm mattress without slipping or bunching.
