Duvet vs Comforter

A Guide to Comforter Sizes: How to Choose the Right Size

There is nothing more painful than buying a brand-new comforter only to find that it’s either too short to cover the sides of the bed or so long that it extends to the floor of your bedroom.

Comforter sizes are not standardized, which means that you could go for a queen size comforter, and it may or may not fit your queen size mattress. This adds to the already existing confusion and can lead to unwanted trips to the store.

Read on to know how to choose the perfect comforter size for your bedroom.

What is a Comforter?

A comforter is a thick and large sack of fabric quilted with fluffy fibers such as silk, down, wool, cotton, or polyester. It is thicker than a duvet and is used by 58.3% of American households.

Comforter Sizes Chart

Although you find standard sizes of mattresses in the market, comforter sizes are not yet standardized. 

Every brand has its own size for comforters. Let’s run through our detailed comforter sizes chart and understand the approximate comforter sizes in inches for each mattress size.

How Can I Know the Right Comforter Size for Me?

Check The Label 

The easiest way to start is to check the labels attached to the bedding and your mattress size. As mentioned in the standard comforter size chart above, the queen comforter size ranges from 81 to 88 inches in width and 86 to 100 inches in length. However, some brands may label it as full comforters, which may be perfect for a queen size bed but too long for a standard full-size bed. 

Add Width and Thickness

You can know the right width of your comforter by simply adding the thickness on each side. Consider a king-size mattress that is 80 inches wide and 11 inches thick: You should buy a comforter that is 80 inches + 11 inches + 11 inches, a total of 102 inches wide for it to be a perfect size. The length can be similar to the length of the mattress, as a comforter does not cover the whole bed. 

Check The Stuffing 

Another factor that can affect size is the stuffing. Down comforters are very soft and tend to fluff up once placed on the bed. Some comforters are labeled as oversized comforters, which means that they are bigger than the average comforter size. Oversized comforters are typically wider and will allow you to cover mattresses with pillow tops. 

Make Sure The Bed Size is Similar

King bed comforter sizes are anywhere between 86 to 88 inches long and 102 inches wide, while California king comforters are 96 to 98 inches long and 107 to 110 inches wide. California king mattresses are long and narrow compared to a standard king mattress, and the comforters for either will not be a good fit for the other one. 

Twin XL comforter sizes will be longer twin mattresses as Twin XL mattresses are 5 inches shorter than twin XL mattresses. Therefore, twin XL comforters cannot be used with twin beds.

Measuring a Mattress With Tape

The key to buying a perfect comforter size for your bed is to know the size of the mattress. Most mattresses will write the measurements on the label. If that is not the case, then the easiest way is to use a measuring tape.

Use a tape and look for the markings in inches. To find out the length, measure from the top of the bed to the foot of the bed. For the width, measure from side to side. 

For measuring how tall or thick your mattress is, lay the mattress down and start measuring from the ground up. Stop when you reach the side of the mattress facing the ceiling. This should tell you how thick the mattress is. Mattresses are generally 90 to 12 inches thick. 

UK Sizes vs US Sizes Comforter

In the UK, comforters are commonly known as duvets. However, one of the differences is that a duvet is used with a duvet cover whereas comforters are generally used without a cover. 

The important thing to note here is that the size between the UK and US is different.

The table below gives a detailed comparison between UK comforter size vs US comforter size.

Final Note

The perfect-sized bedding will make your bed more aesthetically pleasing and comfortable for you. If your comforter is not as long as your mattress, it may lead to exposed legs for you and your partner during sleep. If it is too long, it will look oversized and get dirty faster. 

Comforter size measurement requires research as different sizes are available in each brand. Follow the simple steps mentioned above, and you will surely find the perfect comforter size for your mattress.
