While most standard sheet sizes pair well with their corresponding mattresses, the same can’t always be said of comforters. The perfect comforter provides plush softness to the bed, adequate protection for the sheets, and aesthetic appeal to the bedroom as a whole. To enjoy all the benefits that a great comforter has to offer, it’s important to select one with the right size and dimensions.

Baby Crib Comforters
Dimensions: 28-36 inches wide by 48-52 inches long
Comforters make an excellent addition to your child’s crib, as comforters and other soft blankets provide a smooth, soft, and comforting surface for them to feel safe and snug as they sleep. According to the American Academy of Pediatrics, there is no age that is 100% safe to use a blanket or comforter, but many medical experts agree that comforters and other soft bedding pose little danger to healthy babies in the crib after 1 year of age.
Crib mattresses sizes are regulated by the federal government for safety reasons, so it should be fairly easy to find a comforter that fits neatly within your baby’s crib. Be sure to select a comforter that isn’t too thick for your child, as babies can become overheated if they are tucked in their bedding and comforter for hours at a time.
Dimensions: 66-68 inches wide by 86-88 inches long
Twins make the best mattresses for children, young adults, and bunk beds. Twin comforters should ideally provide enough warmth for one person. That being said, a sheet with a low thread count might not be enough to keep a single sleeper warm. If you’re buying a comforter for a twin size mattress, look for warmer options such as down comforters or even comforters with synthetic fills, which tend to be warmer and retain more body heat within the bed.
Twin XL Comforters
Dimensions: 68 inches wide by 90 inches long
As a popular staple for young adult beds and college dormitories, twin extra long comforters should provide the extra length required by a twin XL mattress. When shopping for a twin XL comforter for a college student, favor models with thicker layering and a higher weight ratio. There’s a good chance that your college student will be studying, napping, and spending more time in general on top of their comforter, so you’ll want one with better durability and more resistance to everyday wear and tear.
Full (Double) Comforters
Dimensions: 81-84 inches wide by 86-88 inches long
The average comforter measurements for a full or double size is around 7 feet by 7 feet. While nearly all full size mattresses have the same length, most full and double size comforters do not and come in different sizes. If you’re buying a new comforter for a full or double size bed, be sure to select one that hangs down over the sides and foot of the bed without retaining too much heat within the bed during warmer weather.
Dimensions: 86-88 inches wide by 96-100 inches long
As a good rule of thumb, most queen mattresses are about 5 feet by 6.5 feet, so queen comforters are commonly around 7 feet by 8 feet to adequately cover the mattress and bed space. It’s perfectly okay to purchase a queen comforter for slightly smaller beds, such as full or twin XL sizes, as the comforter will typically hang down to the ground on the sides and foot of the bed. This keeps the entire bed covered during colder months and saves you from having to cover the space underneath the bed with a bed skirt.
Dimensions: 102 inches wide by 86-88 inches long
Since king size mattresses are the largest standard size, king size comforters should provide enough coverage for at least two sleepers. The thickness of your mattress is an important consideration when shopping for a king size comforter, as deep, pillowtop mattresses will require a wider comforter. Many modern manufacturers offer oversized king comforters for this exact situation, and many oversize king comforters are around 115 inches wide to adequately cover the deeper space.
California King Comforters
Dimensions: 107-110 inches wide by 96-98 inches long
California king size mattress is approximately 6 feet by 7 feet, making it an ideal choice for taller couples. When searching for a California king comforter, be sure that your selection is thin, lightweight, and cool enough to cover the entire family without trapping all of the extra body heat from multiple sleepers within the bed.
Frequently Asked Questions
What’s the difference between a duvet and a comforter?
While the two words are sometimes used interchangeably to describe the top, outer layer of bedding, duvets and comforters aren’t exactly the same. A comforter is a single, flat piece of bedding that is often included in an entire bedding set, while a duvet is a fluffier bed cover that is stuffed with down or synthetic filling. Comforters are used in tandem with the best sheets and blankets to provide a sleeper with adequate warmth and comfort whereas duvets are commonly used by themselves.
What is a duvet insert?
Located inside of the duvet, the duvet insert is simply the inner part of the duvet. Duvet inserts are typically found in plain, white coloration and enhance the comfort of the duvet, and they slide in and out of the duvet cover much like a pillow would slip in and out of a pillowcase.
How long does a high-quality comforter last?
A quality comforter can last 15 to 25 years if it’s properly cared for and used normally. Comforters tend to last longer than duvets because duvets have more filling that can collapse over time or develop cold spots around the stitching pattern.
What materials are typically used in comforters?
Comforters are comprised of either cotton, wool, silk, down, or bamboo. Each material has its own set of advantages and disadvantages, so be sure to select a comforter made from the material that best suits your sleeping preferences.
What’s the best way to clean a comforter?
Before washing your comforter, be sure to read your care and maintenance instructions to avoid any damage that may occur as a result of your cleaning. That being said, it’s generally safe to wash your comforter in your home’s washing machine on a gentle or delicate cycle. Be sure to dry your comforter on low heat to avoid shrinking it, and you can toss a few tennis balls into the dryer with your comforter to help plump up the comforter and evenly distribute the filling.
You can also spot clean the comforter by moving the filling away from the stained area and spraying the comforter with diluted Woolite or a mix of water and baking soda.
It’s important to select a comforter that closely fits your mattress size. In failing to choose the right comforter, you might be stuck with a bed that is too cold or one that doesn’t look quite right if the sides and foot of the comforter are too long or short. It’s rarely a good idea to pair a smaller comforter with a larger mattress, but you can generally pair a larger comforter with a smaller mattress and enjoy a great night of sleep.
