What Are Deep Fitted Sheets – Guide To Choose Perfect Sheet

A good night's sleep is not just about the right mattress or a fluffy pillow; your choice of sheets plays a crucial role, too. Among the myriad options available, deep-fitted sheets have gained popularity for their ability to fit snugly over mattresses of varying thicknesses.

In this comprehensive guide, we will explore what deep fitted sheets are, how to choose the correct depth, measure it accurately, understand the differences between deep and extra deep fitted sheets, and ultimately, decide if they fit your bed best.

What is a Deep Fitted Sheet?

A deep fitted sheet, also known as a deep pocket fitted sheet, is designed to accommodate mattresses thicker than the average. Standard fitted sheets typically have pockets around 7 to 14 inches deep, while deep fitted sheets can go up to 18 inches or more. The extra depth ensures a secure and snug fit, preventing the sheet from slipping off, especially on thicker mattresses.

What Depth Of Fitted Sheet Do I Need?

Choosing the correct depth of a stripe fitted sheet is crucial for a well-dressed bed. Measure your mattress from the top edge to the bottom, including the depth. The depth of your fitted sheet should be equal to or greater than this measurement to ensure it stays in place. If your mattress is 12 inches deep, opt for a fitted sheet with 12 inches or more depth.

How to Choose the Right Deep-Fitted Sheet?

Several factors should be considered when selecting a deep-fitted sheet:

  1. Mattress Depth: As mentioned earlier, measure your mattress depth accurately.
  2. Material: Choose a material that suits your preference and climate. Cotton is breathable and comfortable, while microfiber offers a silky feel.
  3. Thread Count: Thread count indicates the number of threads per square inch. A higher thread count often results in a softer and more durable sheet.
  4. Elastic Quality: Ensure the fitted sheet has high-quality elastic around the perimeter. This helps in keeping the sheet securely in place.
  5. Pocket Depth: Match the pocket depth of the sheet with your mattress depth to ensure a proper fit.
  6. Design and Color: Select a design and colour that complements your bedroom decor and personal style.

How Do You Measure the Depth of a Fitted Sheet?

Measuring the depth of a fitted sheet is a simple yet crucial step to ensure a snug fit. Start by placing the measuring tape at the mattress's top edge and extending it down to the bottom. Take note of the measurement, including any additional padding or toppers. This figure will guide you in choosing a deep fitted sheet with the appropriate pocket depth.

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

The terms "deep" and "extra deep" refer to the pocket depth of fitted sheets. While deep fitted sheets typically have pockets ranging from 15 to 18 inches, extra deep fitted sheets can go beyond 18 inches. The choice between deep and extra deep depends on the thickness of your mattress. If your mattress is on the higher side, an extra deep fitted sheet provides the necessary coverage.

Is 40cm a Deep Fitted Sheet?

Yes, a fitted sheet with a pocket depth of 40cm is considered deep. In inches, this is approximately 15.75 inches. It falls within the range of deep pocket fitted sheets, offering a secure fit for mattresses with substantial depth.

What if the Fitted Sheet needs to be deeper?

Using a fitted sheet with inadequate depth poses the risk of constantly slipping off the mattress, leading to discomfort during sleep. If you find yourself in this situation, it's advisable to invest in a deep or extra-deep fitted sheet that matches the thickness of your mattress. This simple adjustment can make a significant difference in your bed's overall look and feel.

Deep Fitted Sheet Vs. Flat Sheet

While fitted sheets are designed to contour the mattress, flat sheets lie flat on top of the mattress and are tucked in around the sides and bottom. The choice between deep-fitted sheets and flat sheets depends on personal preference. Some people prefer a fitted sheet's neat and tailored appearance, while others appreciate the versatility of a flat sheet that can be easily tucked in or left untucked.


Choosing the proper sheets cannot be overstated in the quest for a restful night's sleep. Deep fitted sheets provide a solution for mattresses of varying thicknesses, ensuring a secure fit and a polished look. By measuring your mattress accurately, considering factors like material and thread count, and understanding the difference between deep and extra-deep fitted sheets, you can decide on the best sheets for your bed.
