Once you’ve found the best mattress, pillow, and bedsheets, you need the right size duvet to complete your sleep setup. Duvets make you feel cozy and comfortable enough for a good night’s sleep.
Duvet sizes determine your comfort and the look of your bed. Longer and wider duvets drape over your bed aesthetically, leaving more room for you to toss and turn underneath.
Finding the right size duvet compatible with your mattress can be challenging. In this size guide, we discuss how to choose the perfect duvet for different standard mattress sizes, without compromising on your comfort and the bed’s aesthetic appeal.
What are Duvets?
Duvets are like soft flat bags made with different kinds of fabric and stuffed with down, or down alternatives, like wool, silk, or polyester. Soft feathers beneath the wings and closest to the belly of geese or ducks are called down. Down is light and fluffy, offering effective thermal insulation. Duvets originated in Europe, where traditionally, down is used to fill large pouches of fabric.
Down duvets feel plush and toasty. They are usually more expensive than down alternative duvets. But down duvets can trigger allergic symptoms such as sneezing, coughing, runny nose, itchy throat, or breathing difficulties. Down alternative duvets are hypoallergenic. They are a good option for those prone to allergies.
The amount of fill determines how fluffy and warm your duvet feels. When buying a duvet look carefully for stitches crisscrossing the duvet—these are important to keep the fiberfill in place. Uneven distribution of stuffing can’t surround you with even comfort and warmth.
Duvets are also called duvet inserts because they are always used with duvet covers. Duvet covers are easier to maintain compared to duvet inserts. Most duvet covers can be machine washed.
The duvet inserts are usually white or cream in color, so duvet covers are used to dress them up. You could also use a coverlet with a duvet for a nicely finished look. Duvet covers are available in different colors and designs to suit your bedroom decor. Both duvets and duvet covers are available in various sizes.
Different Duvet Sizes and Dimensions for Standard Size Mattresses
Duvets form the top layer of your bedding, adding to the aesthetic appeal of your bed. Typically we follow the 12-16 rule when buying duvets, so they are at least 12 inches longer and 16 inches wider than the bed size. You want the overhang to cover the line where the mattress meets the foundation or box spring. But following the 12-16 rule won’t be enough for adequate overhang in case of mattresses taller than 8 inches.
To increase overhang either buy wider and longer mattresses or buy duvet covers with flanges. A flange is a classic decorative accent, typically added along three sides of a duvet cover. Flanges give you an extra 3 to 4 inches on each side of the bed.
While buying a duvet for taller mattresses, it’s best to first measure your mattress depth. Then double that number. That’s how much wider than your bed you want your duvet to be. For example, if your mattress is 14 inches tall, your duvet should be 28 inches wider and 14 inches longer than your bed.
There are no standard dimensions for different duvet sizes. You’ll find twin, full, queen, jumbo queen, king, and jumbo king duvet and duvet cover sizes on the market. But their dimensions vary slightly from brand to brand. It’s better to check with the salespersons or customer service representatives about the exact dimensions.
A twin size duvet may not always be the right fit for a twin size mattress. While buying your duvet, your mattress depth is an important factor. In this section, we discuss the different duvet sizes and their compatibility with the standard mattress sizes.
Twin Size Duvet
Compatible with: Twin and Twin XL Size Mattresses
Twin duvets can range between 64 inches by 89 inches to 68 inches by 88 inches. Twin size duvet dimensions are compatible with twin or twin XL mattresses up to 15 inches tall. Most high-quality mattresses are between 8 to 12 inches deep.
Since the width of twin and twin XL mattresses are the same, a twin duvet is a good fit for both. Twin mattresses measure 38 inches by 75 inches, and twin XL mattresses are five inches longer than twin beds. They are commonly used in children’s rooms and college dorms. Sometimes these single beds are also used by adults living in smaller rooms.
Full Size Duvet
Compatible with: Full or Double, Twin, and Twin XL Size Mattresses
Full size duvets range between 80 inches by 89 inches and 90 inches by 94 inches. They are compatible with most full mattresses. You may also need a full size duvet for twin and twin XL mattress taller than 15 inches. Some soft mattresses may be 16 to 18 inches tall. But be careful about the duvet dimensions. Choose the smaller dimensions in the full size duvet range. A duvet with an increased overhang may touch the floor.
Full size mattresses measure 54 inches by 75 inches. They are 16 inches wider than a twin. Full beds, also called double beds, are not enough to accommodate two adults. But an adult and a child or two children can comfortably sleep on a double bed. Full mattresses are commonly used in guest rooms or studio apartments where space is limited.
Queen Size Duvet
Compatible with: Queen Size Mattresses
Queen size duvets range between 88 inches by 90 inches to 90 inches by 94 inches. They are compatible with queen mattresses up to 15 inches tall.
Queen beds are the most popular of all standard sizes. They are an excellent option for single sleepers while being versatile enough to accommodate a couple. Queen mattresses are commonly used in guest rooms or smaller master bedrooms.
Jumbo Queen Size Duvet
Compatible with: Queen Size Mattresses taller than 15 inches
You need special bed linens for premium quality mattresses or those with pillow tops. A pillow top is an extra layer of padding sewn on top of the mattress to enhance cushioning. This extra layer increases the total depth of the mattress.
Like standard fitted sheets and flat sheets, even standard size duvets don’t have much room for these modern-day, taller mattresses. You need oversized flat sheets and fitted sheets with deeper pockets to fit tall mattresses. Similarly, you need jumbo queen size duvets for queen mattresses taller than 15 inches.
Jumbo sizes are usually 12 to 14 inches wider and longer than their standard counterparts. A jumbo queen size duvet measures around 102 inches by 100 inches. The extra width and length of the duvet drape the tall mattresses on all three sides. Jumbo queen duvets are compatible with queen beds taller than 15 inches.
King Size Duvet
Compatible with: King or California King Size Mattresses
King size duvets range between 104 inches by 90 inches to 104 inches by 94 inches. They are compatible with all king size mattresses up to 14 inches, and Cal King mattresses up to 16 inches tall.
King beds are the widest of all standard sizes, and Cal kings are the longest. A king bed measures 76 inches by 80 inches, while a Cal king is 4 inches narrower and longer than a King. The extra legroom in Cal king beds is perfect for tall people. A Cal king bed measures 72 inches by 84 inches.
Both king and Cal king mattresses are ideal for couples. They have enough space for children as well if they don’t want to sleep in their rooms on some nights. But these big beds can only fit in spacious master bedrooms (ideally measuring 12 feet by 12 feet).
Jumbo King Size Duvet
Compatible with: King Size and California King Size Mattresses
Jumbo king size duvets range between 114 inches by 100 inches to 116 inches by 100 inches. They are needed to drape king beds taller than 14 inches and Cal king beds taller than 16 inches. They are more expensive than the regular king size duvets.

How do you know what size duvet to get?
Your duvet should be wider and longer than your mattress. But how much longer or wider depends on your mattress depth. In case of mattresses up to 8 inches tall, opt for the 12-16 duvet rule: choose duvets 12 inches longer and 16 inches wider than your bed size. Though duvets are available in standard sizes such as twin, queen, and king, their dimensions differ slightly across brands.
Usually, twin, full, queen, or king duvets can be used with their corresponding bed sizes only if the mattresses are up to 8 or 10 inches tall. If you have a taller bed, you may need to upgrade to the next duvet size. For example, to drape a tall twin mattress you may need a full size duvet.
Are full and queen duvets the same size?
It depends from brand to brand. Some manufacturers have full duvets measuring 80 inches by 89 or 84 inches by 90 inches, while their queen duvets measure 88 inches by 90 inches. Other manufacturers market their duvets measuring 90 inches by 94 inches as full/ queen. A queen mattress is 6 inches wider and 5 inches longer than a full mattress. Given the minor difference in dimensions, sometimes one duvet size is suitable for both mattress sizes.
What size duvet is best for a double bed?
Full or double size duvets measuring 84 inches by 90 inches are compatible with double beds up to 15 inches tall. But full size duvets have a vast range. They can be between 80 inches by 89 inches to 90 inches by 94 inches. Some brands market their duvets measuring 88 inches by 90 inches as queen duvets. In that case, you will need queen duvets or the larger dimensions in full duvets for full mattresses taller than 15 inches. Full mattresses, also called double beds, measure 54 inches by 75 inches.
Why is my duvet cover bigger than the duvet?
Duvet cover sizes are slightly larger than the average duvet dimensions to accommodate normal shrinkage and the thickness of the duvet. Cotton, flannel, and microfiber materials are used for making duvet covers. Cotton is preferred due to its breathability, but it may shrink in the first wash. Flannel and microfiber materials are better suited to colder climates. Duvet covers are like pillowcases with one open end into which the duvet is inserted. They work as a protective and decorative cover for duvets.
What’s the difference between a duvet and a comforter?
Duvets are usually thicker and fluffier than comforters. Comforters come in a variety of designs and patterns, unlike duvets which are usually plain white. While duvets are used with a duvet cover, comforters are used with a top sheet, serving as a hygienic barrier between the sleeper and the mattress. While making a bed, both duvets and comforters are used as the top layer of bedding draping the mattress.
Duvets make you feel warm and snug. Depending on the stuffing inside them, some may be used during winters, while others are good for use throughout the year. When you buy a duvet wider and longer than your bed size, it should be big enough to cover your whole body even when you change sleeping positions.
Most duvet sizes are wider and longer than their corresponding bed sizes. While being comfortable, these duvets may not be big enough to drape over taller mattresses. If you have mattresses taller than 12 to 14 inches, you may need to upsize when buying a compatible duvet. Before buying a duvet, it’s best to measure your mattress and ask a customer service representative about the duvet’s exact dimensions.
