Full/Double Size Duvet

Full duvets are 80-90 by 89-94 inches and fit full/double beds. Full beds are popular with single people because there’s plenty of room for one person to spread out and fulls can fit in smaller bedrooms. Couples can also fit on this mattress, but there won’t be much room to spare. The standard full mattress measures 54 by 75 inches.

Queen Duvet

Queen duvets are 88-90 by 90-94 inches and fit queen mattresses. The queen mattress is the most popular bed for both couples and singles; its size makes it big enough for two people to sleep comfortably, but not so big that you need a huge bedroom. The average queen mattress measures 60 by 80 inches.

King Duvet

King duvets are 104-90 to 94 inches and fit king mattresses. The king mattress or king beds is very popular with couples because it gives both sleepers plenty of room for themselves. The standard king mattress measures 76 by 80 inches.

California King Duvet or Jumbo King Duvet

California king duvets are 104 by 100 inches and fit Cal king mattresses. The Cal king mattress is great for tall sleepers because it’s 4 inches longer than the king beds. The average Cal king mattress measures 72 by 84 inches.

What is a Duvet?

A duvet is a bag of fluff that’s quilted to keep stuffing evenly distributed. Thanks to its extra stuff and fluff, the duvet is quite cozy. Many sleepers are comfortable with a duvet as their only blanket.

“Duvet” is french for “down” and traditionally duvets were only filled with these fluffy geese and duck feathers. Nowadays, duvets are filled with all kinds of natural and synthetic materials. Common duvet stuffings are wool, silk, and hollow fiber.

It’s difficult to clean all of the dust out of a down duvet, and this gives some sleepers allergy-like symptoms. These alternative materials create a cozy duvet that’s hypoallergenic. Many synthetic duvets are machine washable, while down can only be dry-cleaned.

How Should a Duvet Fit?

The sides and foot of your bed should have the same amount of the duvet hanging over the edge. It should be long enough to cover the seam where the mattress meets the bed’s foundation but shouldn’t hang all the way to the floor. The general recommendation for a duvet is to find one 12 inches longer and 16 inches wider than the mattress.

There are exceptions to this rule—deeper mattresses need larger duvets to make sure there’s full coverage. When you measure the length and width of your mattress, we recommend you measure the depth too. The best way to do this is to take off all your bedding and measure just the mattress. If you have a pillow top on your bed, keep it on while you measure.

How to Choose the Right Duvet Size?

Choosing the right duvet size involves more than just matching it to the size of your bed. Here’s a step-by-step guide to help you choose the ideal duvet size for your needs:

1. Measure Your Mattress

Begin by measuring both the width and length of your mattress. These measurements will guide you in finding the perfect duvet size for your bed.

• Consider the Drop 

Drop refers to how much of the duvet hangs over the sides of the bed. If you want a more luxurious, draped look with extra fabric on the sides, you may want to go up one size.

• Standard drop: Most duvets match the width of the mattress with a little overhang.
• Oversized drop: A larger duvet adds an elegant draped effect and extra warmth, as it covers more of the sides of the bed.

• Room for Two

Sharing the bed: If two people share the bed, it might be worth going for a larger duvet to avoid “tug-of-war” situations during the night. For example, using a king-size duvet on a queen-size bed provides ample coverage for both sleepers.

• Climate and Weight Considerations

• Climate: In colder climates, a larger duvet can offer more warmth and coziness by covering more of the bed and hanging lower over the sides.
• Weight of the duvet: A larger duvet might be heavier, especially if it’s filled with down or feathers, so factor in personal comfort when sleeping.

• Duvet and Duvet Cover Compatibility

Ensure your duvet cover matches the duvet size: A duvet cover that’s too large will cause the duvet to shift and bunch inside, while a cover that’s too small can make the duvet feel cramped.

1. Consult a Duvet Size Guide

Refer to a duvet size chart or the manufacturer’s recommendations. Use your mattress measurements and your desired overhang to select the appropriate duvet size.

1. Factor in Personal Preferences:

Take your personal sleeping preferences into account. If you tend to move around a lot in your sleep, opting for a larger duvet size might offer better coverage and comfort throughout the night.

• Aesthetic Preferences

• Minimalist look: Opt for a duvet that is just big enough to cover your mattress without much overhang.
• Luxurious look: Choose a larger duvet to create a layered, plush appearance.

• Consider Bed Frame Height

If you have a high bed frame or a box spring, consider a duvet with more overhang. For low-profile or platform beds, a standard-size duvet might look neater.

It’s always a good idea to select a duvet that is slightly larger than your mattress to guarantee complete coverage and avoid any issues with a duvet that feels too small or restrictive during sleep.

Factors to Consider for Choosing the Right Duvet

a. Filling Types

A duvet’s plushness and softness come from its filling. The best choice of filling depends on your individual needs and priorities. Below are the most common types of duvet fillings:
• Down: Down feathers come from the insulating undercoat of waterfowl, making them exceptionally soft and cozy. Our down duvets, for example, are filled with ethically sourced down for a natural, guilt-free comfort experience.
• Feathers: Feather fillings are taken from the outer layer of birds and tend to be more rigid and bulkier than down. However, they result in a lighter-feeling duvet.
• Wool: Wool is hypoallergenic and naturally water-resistant. Duvets filled with wool, like our humidity-fighting duvet, feature merino wool, which wicks moisture away and prevents overheating.
• Synthetic Polyester: A popular down alternative, synthetic polyester mimics the plush softness of down. It’s ideal for those with down allergies or for anyone looking for a machine-washable duvet. Our down alternative duvet, for example, uses soft fiber fill that feels like down but is made from recycled polyester sourced from water bottles.

When selecting your duvet filling, think about what will make you most comfortable during the night. Heavier materials like down provide extra warmth, while lightweight options are better for those who sleep hot. Most duvets come in both midweight and lightweight variations to suit different sleeping preferences.

b. Thermal Rating (Tog)

In some countries, the warmth of a duvet is measured using a tog rating. The higher the tog, the warmer the duvet will be. Consider the season and your personal warmth needs when choosing the appropriate tog rating for your duvet.

c. Weight Considerations

The weight of the duvet is another factor to evaluate. Lightweight duvets are perfect for warmer climates or if you tend to overheat at night, while heavier duvets are ideal for colder environments or for those who prefer extra warmth.

d. Care and Maintenance

Think about the maintenance required for your duvet. Some duvets are machine-washable, while others need to be dry cleaned. Choose a duvet that fits your lifestyle and cleaning preferences.

e. Breathability:

When selecting a duvet, consider the breathability of the material. Natural fillings like down and wool are typically more breathable than synthetic options, allowing for better airflow and temperature regulation during sleep. If you tend to sleep hot, breathable materials are key to staying cool throughout the night.

f. Allergen Sensitivity:

For those with allergies, hypoallergenic duvet fillings are a smart choice. Wool and synthetic fibers, such as microfiber and polyester, are great options because they resist allergens like dust mites and mold.

If you love down but suffer from allergies, look for hypoallergenic down or treated down alternatives that offer similar comfort without triggering sensitivities.

g. Durability:

Durability is another important factor. Down and wool duvets, when properly maintained, tend to last longer than synthetic options. Wool, in particular, is naturally resilient and can maintain its structure over time.

However, if you’re looking for a duvet that’s easy to clean and use frequently, synthetic fills offer long-term value without the need for special care.

h. Seasonal Versatility:

Some duvets are designed for year-round use, while others are tailored for specific seasons. Consider investing in a versatile, all-season duvet or choosing different weights (lightweight for summer, heavier for winter) depending on your local climate and personal comfort needs.

i. Environmental Impact:

For eco-conscious shoppers, the environmental footprint of the duvet materials is important. Look for sustainably sourced fillings, such as ethically harvested down, recycled polyester, or organic wool.

Certifications such as OEKO-TEX or Global Organic Textile Standard (GOTS) indicate responsible and sustainable production practices.

Duvet Covers

Duvets and duvet covers are like pillows and pillowcases. Like pillows, duvets are not designed to be washed regularly. A cover keeps the duvet clean, and when necessary just take it off and wash it like you would your sheets. For those who have feather-filled duvets, we recommend a sturdier cover to keep the quills from poking you during the night.

Duvet covers are easy ways to customize a duvet. Bedrooms sometimes need makeovers, and when that time comes there’s no need to buy a whole new duvet. Just get a new cover!

Varieties of Duvet Cover Fabrics
Duvet covers are often crafted from cotton, but there are other options like flannel, silk, bamboo, and polyester. Below is a breakdown of the most common materials used for duvet covers:

• Cotton: If durability is your priority, cotton duvet covers are a fantastic option. They are available in different styles, such as percale, sateen, jersey knit, or warm and cozy flannel. This wide range ensures that there’s a perfect choice for every type of sleeper and every season.
• Linen: For those who sleep warm or prefer a casual yet sophisticated look, a linen duvet cover is lightweight and breathable. Don’t worry about cooler weather—linen’s natural insulation also makes it a great choice for winter.
• Silk: Derived from silkworms, silk is a luxurious natural fiber known for its smooth, soft, and lightweight texture. However, silk duvet covers tend to be more expensive and require extra care when cleaning.
• TENCEL™ Lyocell: If sustainability is important to you, TENCEL™ Lyocell is an eco-friendly and practical option. Known for its silky softness, excellent moisture-wicking abilities, and breathability, it is one of the most comfortable materials for duvet covers.
• Flannel: A blend of cotton and wool, flannel duvet covers provide exceptional warmth, making them a perfect choice for colder nights.
• Bamboo Fibers: Ideal for people with sensitive skin, bamboo fiber duvet covers are hypoallergenic and gentle to the touch. Additionally, bamboo is a sustainable and organic material, making it a great choice for those with eco-conscious values.
• Polyester: For those looking for a budget-friendly option, polyester duvet covers are a practical choice. This synthetic fiber is not only affordable but also easy to clean, offering a low-maintenance solution for everyday bedding.

Factors Consider When Selecting a Duvet Cover

• Fabric Choice: Select a duvet cover material that aligns with both your comfort needs and style preferences. Popular materials include cotton, linen, microfiber, and silk. Cotton, in particular, is breathable and easy to maintain, making it a common favorite.
• Closure Mechanism: Pay attention to the type of closure. Most duvet covers come with buttons, snaps, or zippers. Choose the closure style that you find the most convenient and practical for your use.
• Design and Aesthetic: Consider the design and color of the duvet cover to ensure it fits your bedroom’s decor and matches your personal style. Solid colors offer a versatile and timeless look, while patterns or bold designs can add a touch of personality and flair to the room.
• Thread Count
  Thread count refers to the number of threads woven into a square inch of fabric. A higher thread count generally means a softer, more breathable fabric, while a lower thread count may be more affordable.
• For duvet covers, a thread count between 200 and 600 is ideal, as it balances softness and durability. Anything below this range risks the possibility of the duvet’s fill seeping through the fabric.
• Ease of Maintenance: Be sure to choose a duvet cover that is easy to clean. While most can be machine-washed, it’s always a good idea to check the specific care instructions to ensure proper upkeep.
• Size Compatibility: Ensure that the duvet cover matches the size of your duvet insert. Duvet covers come in a variety of sizes, including twin, full, queen, king, and California king. A proper fit is essential for both comfort and appearance.
• Weight of the Material: Depending on the season, you may prefer a duvet cover made from heavier or lighter materials. For example, linen and cotton are lighter and more breathable, perfect for summer, while flannel or thicker weaves provide warmth during the colder months.
• Hypoallergenic Properties: If you suffer from allergies or have sensitive skin, consider duvet covers made from hypoallergenic materials such as bamboo or TENCEL™ Lyocell. These options are gentler on the skin and resistant to allergens.
• Wrinkle Resistance: Some duvet cover fabrics, like cotton or linen, tend to wrinkle easily, while others, such as microfiber or polyester blends, are more wrinkle-resistant. If you prefer a crisp, polished look without frequent ironing, opt for a wrinkle-resistant material.
• Eco-Friendliness: For those concerned about the environmental impact of their bedding, materials like organic cotton, bamboo, or TENCEL™ Lyocell are sustainable options that reduce your carbon footprint without sacrificing comfort.
• Durability: Consider how often you’ll be using and washing the duvet cover. High-quality fabrics like cotton percale, linen, and microfiber tend to withstand frequent washing without losing softness or color, making them ideal for long-term use.
• Moisture-Wicking: If you tend to sleep hot or live in a warmer climate, consider a duvet cover made from moisture-wicking fabrics like TENCEL™ or bamboo. These materials help regulate body temperature and keep you cool throughout the night.
• Cost: Set a budget and choose a duvet cover within that range. Some materials, like silk or organic cotton, can be more expensive, while microfiber or polyester covers tend to be more affordable. Finding a balance between quality and cost will help you make the best decision for your needs.

FAQs

What’s the difference between duvets and comforters?

Duvets and comforters are similar. However, duvets are fluffier and one color while comforters are flatter and usually colorful. Also, while a comforter should be paired with a top sheet a duvet is designed to be your only bed covering. The removable cover acts as the top sheet.

Can my duvet go in the washer and the dryer?

A duvet isn’t designed to take regular trips through the washer and dryer; that’s why it has a cover that’s easy to take off and wash. You should clean your duvet every 3 to 6 months and how you clean it depends on what it’s made of. Down duvets should only be dry cleaned, while many synthetic-filled duvets are machine washable. We recommend you always read and follow the care instructions carefully.

What size duvet is ideal for a double bed?

A full or double size duvet measuring 84 inches by 90 inches works well with double beds that are up to 15 inches in height. However, full size duvets come in a wide variety of dimensions, ranging from 80 inches by 89 inches to 90 inches by 94 inches. Some brands label duvets that are 88 inches by 90 inches as queen size. In such cases, for full mattresses that are taller than 15 inches, you may need to opt for queen size duvets or larger full-size duvets. Full mattresses, also known as double beds, typically measure 54 inches by 75 inches.

How much bigger should a duvet cover be than the duvet?

Your duvet cover should be close to the same size as the duvet but just a bit bigger. Many covers are made of materials like cotton and shrink a bit in the first wash. The extra size makes sure you have a cover that’s a snug fit for your duvet.

Are full and queen duvets interchangeable in size?

This varies between brands. Some manufacturers produce full size duvets that measure 80 inches by 89 inches or 84 inches by 90 inches, while their queen duvets measure 88 inches by 90 inches. Other brands may offer 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 small difference in size, one duvet size may sometimes be suitable for both full and queen mattresses.

What kind of duvet is best for all seasons?

Duvets filled with wool or down are good choices for all seasons. Wool is a natural thermoregulator, keeping you warm in the winter and cool in the summer. It also wicks away moisture, helping sleepers who sweat at night stay nice and dry. Wool is hypoallergenic.

Down is also a natural thermoregulator; it is cozy in the cold and breathable in the summer. It is difficult to clean, however, and gives some sleepers allergy-like symptoms. A down duvet is a good all-season choice as long as it is dry cleaned every 3 or 6 months, and the sleeper isn’t sensitive to dust particles.

Can I put a duvet cover over my comforter?

A duvet cover is an easy way to add variety if you’re bored of your comforter. Most comforters are flatter than duvets, and won’t fit well inside the cover. For those who don’t mind the looser fit, this is still an easy way to change the look of your room. You should buy a cover with the same dimensions as your comforter.

What does “fill weight” mean for a duvet?

The fill weight refers to the amount of down, measured in ounces, inside a duvet.

Fill weight works in tandem with fill power, which is the volume occupied by one ounce of down. The higher the fill power, the better the quality of down and the warmer the duvet will be.

How do you determine the right duvet size?

Selecting the proper duvet size is key to ensuring a cozy and well-fitted bed. To find the right size duvet, consider the following steps:

• Measure your mattress: Use a tape measure to determine the length and width of your mattress, measuring from edge to edge for accuracy.
• Think about your desired coverage: Decide how much coverage you want. Some prefer their duvet to drape generously over the sides for a more elegant look, while others like a snug fit. Consider your personal style when choosing the perfect fit.
• Factor in mattress thickness: If you have a thicker mattress or use a mattress topper, make sure to account for this extra height when choosing a duvet size. The height from the top of the mattress to the length of the duvet should be included.
• Check a duvet size chart: Refer to the sizing chart or guide provided by the duvet manufacturer or retailer. These charts typically suggest suitable sizes for twin, full, queen, king, and California king beds. By taking these steps—measuring your mattress, deciding on coverage, considering thickness, and using a sizing chart—you’ll be able to find the best duvet size for your bed.

Are there cruelty-free duvets?

Duvets are typically filled with down (feathers), but cruelty-free options are available if this is important to you. Many companies now offer alternative fills made from sustainable materials like bamboo, microfiber, or microgel. These options provide comfort without the use of animal products.

Summing it Up

The right-sized duvet depends on the length, width, and depth of your mattress. Finding these measurements is the best way to get the right fit. Each brand’s sizing is a little different, so be sure to check the duvet’s dimensions in the product description before you make your purchase.

With a duvet, redecorating your bedroom is as easy as buying a new cover! It’s also a low-maintenance choice; just take off the cover and wash it with your sheets. Once you know what size to buy, duvets are a cozy and customizable bedding choice.
