What are fitted bed sheets?

In India, fitted bed sheets, also sometimes called elastic bed sheets, are a popular alternative to traditional flat sheets. Unlike flat sheets that simply drape over the mattress, Belong’s fitted bed sheets have elasticated corners on the whole bed sheet and sides that hug the mattress snugly. This eliminates the need for constant tucking and the deep pockets keep the sheet securely in place throughout the night, offering a neater and more comfortable sleeping experience.

What are flat bed sheets?

In India, where bed sheets are often used as the primary sleeping surface, flat bed sheets are a household staple. Unlike fitted sheets that have elasticated corners to hug the mattress, flat sheets are simply rectangular pieces of fabric. They come in various sizes to fit single beds, double beds, king-sized beds, and even larger options for family use.

Made from breathable materials like cotton or cotton blends, flat sheets provide a comfortable sleeping surface during both hot and cold weather. They are also versatile. During the summer months, a single flat sheet may be sufficient for comfortable sleep. In winter, flat sheets can be layered with blankets or comforters for added warmth. Flat sheets are also easily washable, making them a hygienic and practical choice for Indian households.

4 Tips to turn flat bed sheets into fitted bed sheets?

Ever wake up to a tangled mess of a flat sheet? The struggle is real, especially on nights when a secure, tucked-in feel is desired.  There's a hidden weapon in your linen closet – that trusty flat sheet can actually be transformed into a perfectly fitted one.

Here, we'll explore 4 methods on how to turn flat bed sheet into fitted sheet bed sheet, catering to both sewing enthusiasts and those who prefer a no-sew approach:

Method 1: The No-Sew Solution (Simple & Quick!)

Perfect for those who are short on time or sewing skills, this method offers a quick and easy way to create a fitted sheet feel:

  • Prep and Measure: Lay your flat sheet flat and measure your mattress. You'll need to know the length, width, and depth (height) of your mattress to ensure a proper fit.
  • Mark and Cut: Based on your mattress measurements, mark the sheet with fabric marker or chalk. You'll essentially be creating envelope corners to tuck under the mattress. Typically, you'll want to add an allowance of about 12-14 inches on each side (length and width) for tucking, and an additional 3-4 inches for the corner depth. Once marked, carefully cut out the designated corner sections.
  • The Tucking Magic: Here comes the fitted sheet transformation! Place the modified sheet over your mattress, aligning the straight edges. Now, tuck the excess fabric from the sides and the top under the mattress, creating a snug fit. The corner sections you cut out will fold inwards and tuck under the mattress corners, providing a more secure hold.

Method 2: The Sewing Savvy Approach (For a More Polished Look)

If you have some sewing skills and prefer a cleaner finish, this method is for you:

  • Prep and Measure: Follow steps 1 and 2 from the no-sew method to measure your mattress and mark the sheet for cutting the envelope corners.
  • Pin and Sew: Instead of simply tucking the fabric, we'll create proper fitted corners. Lay the sheet flat with the marked side facing up. Fold the excess fabric from the sides and top inwards (based on your markings) and pin them in place along the straight edges. This creates the envelope corners.
  • Sewing Time: With a sewing machine, sew along the pinned edges, creating a secure seam that encloses the corners. You can use a straight stitch or a zig-zag stitch for added strength. Once finished, remove the pins and enjoy your newly created fitted sheet!

Bonus Tip: Adding Elastic for Extra Security (Optional):

For an even more secure fit, you can incorporate elastic into the corners during the sewing process. Simply purchase some lightweight elastic (⅛ inch or ¼ inch width) and sew it along the raw edge of the fabric before creating the corner seams. This adds a gentle tension and keeps the fitted sheet snug around the mattress.

Method 3: The Fitted Sheet Remix (For Repurposing Old Fitted Sheets)

  • Measure and Match: First, measure your target mattress (the one you want the new fitted sheet for). Then, lay the old fitted sheet flat and measure its usable fabric area (excluding the elasticated corners).
  • Strategic Cutting: Here's the key. Carefully cut straight sections from the old fitted sheet, ensuring the total usable fabric area matches the measurements of your target mattress. You might need to cut from the sides, the top, or a combination of both, depending on the size difference.
  • Sewing Up the New Sheet: With the fabric pieces cut, sew them together using a straight stitch to create a new, rectangular sheet. Now, follow the sewing method (Method 2) from our previous guide, creating envelope corners and sewing them shut. This essentially creates a brand new fitted sheet from the usable fabric of your old one!

Method 4: The Deep Pocket (For Extra Deep Mattresses)

  • Measure and Mark: Measure the depth of your mattress and add an allowance of 4-6 inches for proper tucking. Lay your flat sheet flat and mark a new perimeter line on the fabric, taking into account the additional depth needed.
  • Fabric Panels (Optional): If the extra depth is significant, you might need additional fabric. Purchase fabric that complements your flat sheet and cut panels to the desired depth (based on your measurements).
  • Sewing the New Depth: If using fabric panels, sew them securely to the existing flat sheet along the marked perimeter line. If not, simply fold the excess fabric from the marked line inwards and pin it in place.
  • Creating the Corners: Following Method 2 (sewing approach), create envelope corners by pinning and sewing the folded fabric along the sides and top. This creates a deeper pocket that can comfortably fit your thick mattress.

The Final Word:

With these methods, you have a toolbox to tackle various flat sheet transformations. Remember, a little resourcefulness (or "jugaad" as we say in India) can go a long way in creating comfortable and secure sleep solutions. So, don't hesitate to experiment and find the method that best suits your needs and your existing bedding!


  1. My flat sheet is too small for my mattress. Can I still turn it into a fitted sheet?

It depends on the size difference. For minor discrepancies, the no-sew method might work by tucking creatively. However, for larger differences, you might need to try the fitted sheet remix method (using an old fitted sheet) or purchase additional fabric for the deep pocket challenge.

  1. I don't have any sewing experience. Can I still achieve a fitted sheet feel?

Absolutely! The no-sew method is perfect for you. Simply mark and cut the corners of your flat sheet, then tuck the excess fabric under the mattress for a secure hold.

  1. What type of fabric is best for a flat sheet to fitted sheet transformation?

Cotton or cotton blends are ideal choices. They're breathable, comfortable, and relatively easy to work with, making them perfect for sewing or tucking.

  1. I have an old fitted sheet with a ripped seam, but the fabric is still good. Can I use it for anything?

Yes! The fitted sheet remix method can give your old sheet a new life. By cutting usable fabric sections and sewing them together, you can create a brand-new fitted sheet for a different-size mattress.

  1. My mattress is extra deep. How can I ensure the fitted sheet has enough depth?

The deep pocket challenge method addresses this. You can either use the extra fabric from your flat sheet (if enough) or purchase additional fabric panels to create the necessary depth for your mattress.

  1. What safety precautions should I take when working with fabric and scissors?

Always use sharp scissors to avoid frayed edges. Work in a well-lit area and be mindful of finger placement while cutting or sewing.
