Measuring Guide for Bed Sheets & Duvet Covers

In our measuring guide, you can find how to take the dimensions of your mattress or duvet insert correctly so you can order the right size of bed sheets or duvet cover to fit perfectly. Sheet sizes vary depending on the type of bedding needed. Are you looking for flat or fitted sheets? Some bed sheet sizes can also be up to your personal taste. Find all the details you need to order the correct size for your new bedding set.

What Is the Standard Size of Sheets?

Enjoy custom made sheets for all standard bed sizes available on the US market. ALETTA SMIT HOMEWARE has assembled an extensive collection of North American bedding sizes available online.

You can select any desired bed sheet dimensions, whether you choose from the linen size chart or provide us with specific dimensions. For instance, you can look up what the full size sheet dimensions are for both full flat and fitted sheets. Do you own an oversized bed? You will be happy to know that Alaskan, Texas, and Wyoming King beds are also covered. You’d only need to measure the size of the mattress to request fitting oversized bed sheets.

Custom Bedding’s linen size chart is integrated into the online ordering tool to make your shopping easy and smooth.

Measurements for all products are depicted as follows:

Width x Length, for flat sheets and duvet covers

Width x Length x (mattress) Depth, for fitted sheets

ALL OF OUR PRODUCTS ARE MADE TO ORDER.

How to Check Fitted Sheet Sizes?

To get your perfect fitted sheet size, all you need to do is to enter the measurements of your mattress only. This is why measuring for a custom fitted sheet is very simple. Take these 3 steps:

1. Measure the width of the mattress (W)
2. Measure the length of the mattress (L)
3. Measure the depth of the mattress (D)

For your convenience, use a measuring tape, get a pen and a piece of paper. To measure the width, stretch the measuring tape across the width (W) of your mattress. To get the length, place the tape at a top mattress corner, where the headboard is. Then, stretch it towards the footboard to meet the bottom mattress corner. This is the length of your mattress. To take the depth (or thickness), measure the distance between the top of the mattress* and its bottom. This dimension helps us to determine how deep the pockets of your fitted sheet must be.

*However, if you have a mattress pad or topper, you would have to enter the total height. The extra padding would surely add a few inches on top of the bed. You might need some deep pocket sheets. Don’t worry about determining the fitted sheet depth. We will do that for you and also allow for shrinkage of the fabric.

How to Take the Right Dimensions of Flat Sheets?

When it comes to dimensions of flat sheets, they are mostly up to your taste - you need to specify only the desired length and width. Keep in mind that these measurements should extend over the size of your mattress. We will cut and sew the fabrics with shrinkage in mind.

How much would you like your custom flat sheet to drape? Maybe you want to tuck it all in or let it hang freely? Add those inches twice to the width of your bed, as the flat sheet will cover both sides of your mattress. For the length of the flat sheet, you’d need to consider if you need it to go all the way over the footboard or not.

Now that you have calculated the length and the width of your flat sheet, you are good to go. Then, use the ordering tool to calculate the price for your top sheet:

1. Enter the desired width of the top/flat sheet (finished product)
2. Enter the desired length of the top/flat sheet (finished product)

How to Measure Sheets for a Round Bed Mattress?

Circular shaped beds require custom round bedding that matches their shape and size. How to measure the round mattress, though? First, you’d need to get the size of the diameter right.

The length and width are the same in this case. Then, check the thickness of the round mattress. For example, round King beds usually have a diameter of 87”, and their thickness is anywhere between 10” to 12”.

Do you need a flat sheet for your round bed? Think about how much you’d like it to drop over the mattress. Keep in mind that the ultimate shape of a top sheet for a round bed is rectangular.

For the fitted round sheet, you have to enter the diameter. Then, fill in the depth (plus topper depth, if used) of the circular mattress. This number will show our team your fitted sheet depth.

We cut and sew all fabrics with shrinkage in mind.

What Size Duvet Cover Do I Need?

If you are shopping for custom duvet covers, you’d need to know the size of your duvet insert or comforter. The ordering tool will ask you for two dimensions: width (W) and length (L). These numbers stay for the length and width of your duvet insert or comforter. We will make the duvet cover with zipper closure to the size of the insert. The zipper will be placed at the width.

1. Measure the width of your duvet insert or comforter.
2. Measure the length of your duvet insert or comforter.

When you enter the width and length of the insert, the ordering tool will automatically calculate the price of the fitting duvet cover. We will estimate the final dimensions so it can fit perfectly. Also, we cut and sew the fabrics with shrinkage in mind.

Shrinkage of the Fabric and Sheet Sizes

Cotton is a natural fiber, and as such, it will suffer a certain amount of shrinkage, typically about 2 to 5% upon initial washing and drying cycles. When manufacturing products, we allow for such shrinkage and cut the fabric a little larger so that your linen shrinks to the correct size when you first wash it.
