Published April 28, 2010 | Updated July 1, 2015

If you're an international shopper, the bedding you want is probably measured using a system to which you're not accustomed. You need to know how to buy bedding to fit your mattress, and the names of the mattress sizes are often different from region to region. This international bedding size conversion guide is here to give you an easy reference when you're online shopping for bedding.

Bedding Shopping Tips:

  • Shopping for Mattresses

    Similar mattress sizes may have different names in different countries. Mattresses of the same name may vary by a few inches in different countries; sheets will usually fit if the mattress is approximately the same size -- within a few inches or centimeters. Mattresses from different manufacturers will have different depths; be aware of these when selecting your fitted sheets. Use your mattress size to determine which size memory foam mattress topper or feather bed you need.

  • Shopping for Fitted Sheets

    Your fitted sheet needs to be as close to your mattress size as possible to ensure that it will fit onto your mattress snugly. The pocket depth of fitted sheets may range from 10 inches (25 cm) to 18 inches (46 cm). Be sure to measure your mattress height before selecting a fitted sheet.

  • Shopping for Flat Sheets

    Flat sheets are usually sold in sets with fitted sheets. It's most important that your flat sheet is wide enough. If it's a little long, you can fold it under the mattress. If you use a duvet with a washable cover, you don't need a flat sheet.

  • Shopping for Children's Bedding

    Crib mattresses are 28 inches by 52 inches. Crib bedding needs to be an exact fit to the mattress for the safety of the child. Toddler mattresses are the same size as crib mattresses; the frame is just set lower to the ground, so the child can get in and out of bed independently. You can continue to use the same size sheets but will probably want to add more blankets to the bed.

  • Shopping for Duvet Covers

    In British English, a duvet is known as a quilt, while in American English, duvets are down comforters which require a cover. Duvet covers are also known as quilt covers. The covers are meant to be used without flat sheets or other blankets. Duvet covers do not need to be a precise fit but should be as close as possible.

  • Pillowcase Sizes:

    Pillowcases and pillow shams are usually about 3 to 5 inches (8-13 cm) larger than the pillow itself, so the pillowcase size just needs to be close. Watch out for the tricky names:

What Shoppers Are Saying

Style & Strength

Love my new canopy bed!!! It's my 1st ever, and it makes a very "stylish, cool, contemporary, 'sexy-ish' impression..." Everyone that has seen it, "loves" it. Orignially, I was desiring a more "frilly/girly" looking bed, with twisted iron patterns on head and foot boards, fancier finials, etc., because ...

I'm happy. It's what I expected.

I'm pretty happy with the product so I'll give a 4 out of 5. I did get what I paid for. Don't expect the equivalent of a $*** down comforter for the that price. You just won't get it. The ad is somewhat misleading in that it does not indicate the percentage of down, in the ad. Leaving one to mistakenly ...

The future is now..

Let me start by saying I am a real person. A co worker began talking about his $3K "T-Pedic" bed and really piqued my curiosity. I have a Latex bed and have been happy with it for some time. Well, I stumbled onto Overstocks' memory foam section and saw the 1400+ positive reviews on this 4" topper so ...

Love it, but too short on sides for 14" mattress

Lovely & charming, but fat-matressed folks, beware! We have 14-inch mattresses (2 XL twins, adjustable) and the comforter is 4" TOO NARROW OVERALL on SIDES to meet the bottom of the mattress on both sides. For now, the side not visible from the door is too short, with 4" of mattress showing. The photo ...
