What are the different types of sheets?

  1. Fitted Sheets

Fitted sheets are elasticated at the edges, and they have the exact size of the mattress. Big bed sheet sizes may fit small mattresses, but the reverse is not possible. Ideally, a fitted sheet should only be used with its corresponding mattress.

  1. Flat Sheets

Unlike a fitted sheet, flat sheets are bigger than the mattresses they are made for, as they are not elasticated and need to be tucked under them. You will know whether the new sheets are good for your mattress if you look at the sheet’s dimensions.

If the flat sheet is bigger than your mattress by at least 4 inches, then you will have a good fit. Naturally, a small, flat sheet will fall short of fitting your mattress properly.

  1. Duvet Cover

Duvet covers are nothing but a covering for your comforter that drapes along the edge of the mattress and covers it completely. Unlike bed sheets, you cannot tuck the comforter under the mattress. Duvet covers range between 70 - 100 inches in width and 70 - 106 inches in length. For best results, get right size duvet cover that nicely complements your comforter size.

  1. Bed Skirt

If you do not use a mattress foundation or your bed frame does not have a solid bottom, a bed skirt comes to your rescue and bridges the gap between the bed and the floor. However, instead of a bed skirt, you can also use an oversized bed sheet and let the sheet hang along the sides instead of tucking it.

How to find the right bed sheet for you?

Finding the right sheet starts with knowing the dimensions - length, width, and mattress depth. If you know them, well done. Otherwise, you can follow these steps to quickly identify which of the standard mattress sizes your bed fits.

Step 1: Strip your bed of everything - sheets, pillows, linens and bare the mattress

Step 2: Take a measuring tape and hold it end to end from one side of the mattress to another. As you measure across, you now have the width

Step 3: To measure the length, hold the tape from along the center and measure it end to end from the top to the bottom of the mattress.

Step 4: To measure the mattress depth, pick a point on the upper edge of the mattress and work your way down to the corresponding lowest point on the mattress’s lower edge. Be careful not to include your box spring or foundation in this process.

Once you've got your mattress measurements sorted, it's time to choose the perfect bed sheet. Your fitted sheet should fit snugly around the mattress, without any wrinkles or gaps. And your flat sheet should be larger than the mattress, with enough fabric to tuck in on all sides. This will keep it in place and prevent it from slipping off during the night. Plus, it'll be long enough to cover your pillows for that picture-perfect look.

If you're in the market for a duvet cover, make sure it matches the size of your comforter or duvet. This way, you can guarantee a snug fit and prevent any shifting or sliding.

Conclusion

By determining the size of your mattress and its depth, you can effortlessly choose the correct sheet size. Furthermore, understanding the various sizing standards used in different countries can be helpful if you plan to buy sheets from overseas. Now that you know all about finding the right bed sheet size, kick back, unwind, and let your worries drift away. Sweet dreams!
