In this comprehensive guide, we’ll walk you through everything you need to know about duvet sizes, including a sizing chart, tips for choosing the right size duvet, and answers to frequently asked questions.

What is a Duvet?

Before we dive into the world of various duvet sizes and dimensions, let’s clarify what a duvet is. A duvet is a quilted blanket that goes inside a duvet cover. It serves as a cozy and decorative top layer for your bed, providing warmth and comfort. The duvet cover serves as a protective layer that you can take off and wash easily. The duvet and duvet cover create a stylish and functional bedding ensemble.

Duvet Size Chart

In order to ensure that your duvet fits your mattress perfectly, it is crucial to have a comprehensive understanding of the available various duvet sizes. Keep in mind that duvet sizes may vary slightly between brands. Refer to the following duvet size chart as a general guideline:

Keep in mind that these sizes are close estimates and might differ a bit depending on the brand. It’s always a good idea to check the specific measurements the manufacturer provides before purchasing.

Understanding Duvet and Duvet Cover Sizes

Now that we have a general idea of the duvet sizes available let’s explore each king-size duvet in more detail.

Twin Duvet Size

A twin-sized duvet is designed for a standard twin mattress, which measures 38″ x 75″. However, twin-size duvet part sizes can vary between brands. For example, a twin Casper mattress requires a duvet size of 74″ x 98″. When shopping for a twin duvet, it’s important to consider the specific dimensions provided by the manufacturer to ensure a proper fit.

Twin XL Duvet Size

A twin XL mattress is five inches longer than a standard twin, but the width remains the same. Therefore, a twin-sized duvet should fit both twin and twin XL mattresses. The recommended duvet size for a twin XL mattress is 74″ x 98″. Again, it’s crucial to check the dimensions provided by the brand to ensure compatibility with twin beds only.

Full Duvet Size

A full-sized bed is a popular choice for guest bedrooms or smaller master bedrooms. A full mattress typically measures 53″ x 75″. When it comes to king beds and duvet sizes, a full duvet should be around 95″ x 98″. However, it’s important to note that duvet sizes may vary between brands, so it’s best to check the specific measurements provided by the manufacturer.

Queen Duvet Size

A queen-sized bed is a versatile option for both guest bedrooms and primary bedrooms. The dimensions of a queen mattress are usually 60″ x 80″. For a full queen bed with a duvet, the recommended size is 95″ x 98″. It’s worth mentioning that queen-size sheets are slightly larger than full-size sheets, so be sure to choose a duvet cover that matches the dimensions of your duvet.

King Duvet Size

A king-sized bed offers ample space and luxury. King mattresses typically measure 76″ x 80″. In order to create a plush and stylish aesthetic for a double bed, it is recommended that a king-sized duvet measuring 111″ x 98″ should be used. Additionally, select king-sized sheets measuring 112″ x 102″ to complete the ensemble.

California King Duvet Size

A 111″ x 98″ duvet size is recommended for those with a spacious California king mattress. However, it’s important to note that some brands may offer slightly different dimensions for California queen beds and king duvets. Always refer to the specific measurements provided by the manufacturer to ensure a proper fit.

Now that you know which duvet size to choose, it’s time to consider the factors that make a duvet and cover the perfect match for your needs. Here are some key features to look for in a full-size duvet:

Cover Fabric

Duvet covers are typically made from various materials, each offering its own benefits. Here’s an overview of the most common size duvet cover fabrics:

  • Cotton: Cotton is a famous choice for duvet covers due to its breathability and softness. Egyptian cotton is known for its luxurious feel, while Supima cotton is a high-quality, durable option.
  • Silk: Silk duvet covers are smooth, soft, and airy. They provide a luxurious and elegant look to your bedding ensemble. However, silk duvet covers may require special care and can be more expensive.
  • Bamboo Fibers: Duvet covers made from bamboo fibers are a sustainable and organic option. They are hypoallergenic and are gentle on sensitive skin.
  • Flannel: Flannel duvet covers are perfect for colder climates, providing extra warmth and coziness. They are made from a blend of cotton and wool.
  • Polyester: Polyester duvet covers are budget-friendly and easy to care for. They are a great option for those looking for a low-maintenance bedding solution.


The fill of a duvet refers to the material inside that provides warmth and loft. Here are the most common types of duvet fills:

  • Down: Down duvets are filled with the soft feathers found under the outer feathers of waterfowl. They are known for their exceptional warmth and lightness. 
  • Feathers: Feather-filled duvets provide a slightly heavier and more substantial feel compared to down duvets. They offer a good balance of breathability and warmth.
  • Wool: Wool duvets are hypoallergenic and naturally resistant to dust mites. They provide excellent insulation and moisture-wicking properties, helping you maintain a comfortable sleep temperature.
  • Synthetic Polyester: Synthetic polyester duvets are a popular choice for those with allergies or vegan preferences. They mimic the softness and loft of down without using animal products. 

When choosing a duvet fill, consider your personal preferences for warmth, breathability, and environmental impact.

Thread Count

Thread count is the number of threads in every square inch of fabric. It’s a way to measure how good and long-lasting a duvet cover is. Usually, a higher thread count means the cover will feel softer and more luxurious. However, it’s important to note that thread count is not the sole factor determining the quality of a duvet cover. Other factors, such as fabric type and construction, also play a significant role.

A thread count ranging from 200 to 600 is ideal for a duvet cover. This range offers a good balance between softness and durability. Keep in mind that excessively high thread counts may result in a heavier and less breathable fabric.


To help clear up any remaining questions you may have about duvet part sizes and dimensions, here are answers to some frequently asked questions:

How do you know what size duvet to get?

Duvet sizes can vary between brands, so it’s best to measure your mattress and refer to the duvet dimensions provided by the manufacturer. Choose a duvet size that corresponds to your mattress size for the best fit.

Do I need a duvet cover?

Using a duvet cover is highly recommended. It acts as a protective barrier for your duvet, keeping it clean and extending its lifespan. Plus, duvet covers are easily removable and machine-washable, making them convenient to clean and maintain.

Should your duvet cover be the same size as your duvet?

Duvet covers are typically designed to be slightly larger than the duvet insert. This extra room allows for a fluffier appearance and makes inserting the duvet into the cover easier. However, always check the dimensions the duvet insert manufacturer provides to ensure a proper fit.

Are full and queen duvets the same size?

While most full and queen-sized duvets have the same dimensions, it’s important to note that different brands may have slight variations in dimensions to guide their full and queen duvet sizes. Always check the specific measurements provided by the manufacturer before making a purchase.

What is the difference between a duvet and a comforter?

A duvet has two parts: a cover and an insert. The cover acts as a protective layer and can be easily removed for washing. On the other hand, a comforter is a one-piece quilted bedding item that does not require a separate cover. Both duvets and comforters offer warmth and comfort but have different maintenance requirements.

What is the fill weight of a duvet?

The fill weight refers to the amount of filling inside a duvet, typically measured in ounces. It affects the overall warmth and loftiness of the duvet. Higher fill weights generally indicate a warmer duvet. However, it’s important to consider your personal preferences and the climate in which you live when choosing a full weight.

Can I machine wash a duvet?

Most duvets can go in the washing machine, but it’s important to read the care instructions from the manufacturer. Some duvets may require special care or professional cleaning. When washing a queen-size duvet top, always remove the duvet cover and use an extra-large capacity washer and dryer for larger sizes.


Choosing the correct duvet and bed size is important to make your bed comfy and look good. By understanding the different duvet sizes available and considering factors such as cover fabric, fill, and thread count. Remember to check the specific measurements provided by the manufacturer and follow the care instructions to ensure the longevity of your duvet. You can transform your bed into a cozy sanctuary for restful nights and sweet dreams with the right duvet size and quality.
