The Complete Chart for Perfect Fit, Comfort, and Effortless Style
1. Introduction: Why Duvet Sizing Matters
When it comes to creating a cozy, stylish, and comfortable bedroom, your bedding sets the tone. One essential element is the duvet — the plush insert that gives your bed its warmth and loft.
To protect your duvet and elevate your style, you’ll need a duvet cover — the removable outer layer you can wash or change anytime. (For those familiar with comforters, a duvet is essentially the insert that goes inside a removable, washable cover.)
That’s where Beddley’s Easy-Change® duvet covers come in. Thoughtfully designed with a patented three-sided zipper, they make changing your bedding 10× faster — combining innovation, comfort, and effortless elegance in one perfect layer.

2. What Is a Duvet or Comforter? Understanding the Basics
A duvet (often called a comforter) is a soft, flat bag filled with down, feathers, or synthetic fibers that provides insulation and warmth while you sleep.
Unlike a quilt or bedspread, a comforter or duvet is typically designed to go inside a removable duvet cover, which protects it and adds style to your bedroom. The cover allows for easy washing and effortless style updates - you can refresh your room in minutes without replacing the whole duvet.

Beddley’s Easy-Change® duvet covers take this concept even further - thanks to our innovative three-sided zipper design, you can insert or remove your duvet in seconds, without the struggle or “duvet wrestling” traditional covers cause.
3. Understanding Duvet Sizes: How to Choose the Right Fit
Now that you know the difference between a duvet, a duvet cover, and a comforter, it’s time to find the perfect size for your bed.
Duvet dimensions vary slightly between brands, but understanding standard measurements helps you achieve the ideal look and feel — whether you prefer a snug fit or a luxurious hotel-style drape.
Use the duvet size chart below to compare Twin, Full, Queen, King, and California King dimensions, and discover how a perfectly fitted duvet can completely transform the way your bed looks and feels.
4. How to Choose the Right Duvet or Comforter Size for Your Mattress
Choosing your duvet size is simple if you follow these five steps:
1️⃣ Measure your mattress — note both width and length to find the right duvet cover size chart.
2️⃣ Consider overhang when selecting your bed sheet for a polished look - decide whether you like a snug or draped look.
3️⃣ Account for mattress thickness - deep mattresses or toppers need more coverage.
4️⃣ Check the size chart above - match dimensions before purchasing.
5️⃣ Match your cover and insert to ensure a seamless look for your bed sheet - make sure your duvet cover aligns with your duvet’s size.
Tip: It’s better to size up slightly than end up with a cover that’s too small or tight.

10. FAQ - Duvet Sizing Questions People Ask
What duvet sizes do hotels use for that luxurious look?
Luxury hotels often use a king-size duvet on queen beds to achieve a full, draped effect, especially when using a king-sized duvet. You can recreate this same look at home with Beddley’s Easy-Change® duvets for that crisp, five-star finish every day.
What are the sizes of duvets?
Standard duvet inserts range from 68″ × 86″ for Twin beds up to 104″ × 96″ for California King. See the full chart above for exact inch-to-centimeter conversions.
How to determine duvet size?
Measure your mattress width and length. Then choose a duvet that extends 6–8 inches beyond each side for the perfect overhang.
Should your duvet be the same size as the bed?
Not necessarily — choosing a slightly larger duvet creates that plush, hotel-style look. For instance, many prefer a King duvet on a Queen bed for a luxurious drape, or an oversized Queen on a full-sized bed for added coverage and elegance.
What duvet size is best for a king bed?
A king-size duvet typically measures 106" × 90", offering generous coverage for a standard king mattress. For a longer, more tailored drape — especially on deeper or extra-tall beds — some prefer a California King duvet (104" × 96"), which provides additional length for full coverage and a refined, hotel-style finish.
What duvet size is best for a queen bed?
A queen duvet typically measures 88" × 92", offering the perfect balance of coverage and style for most queen mattresses. For that indulgent, hotel-style look, consider sizing up to a king duvet to achieve an elegant, overhanging drape.
Check the duvet size chart for exact U.S. dimensions in both inches and centimeters.
What size duvet is best for a double bed?
A Full (Double) duvet offers balanced coverage — ample enough for comfort, yet neatly tailored for a clean, refined look without excessive overhang. This size fits full-sized mattresses beautifully and creates a cozy, hotel-style finish in smaller bedrooms or guest rooms.
Are double and queen duvets the same size?
No - a double (Full) duvet typically measures 86″ × 86″, while a Queen duvet measures 88″ × 92″. That extra length and width give a queen bed better drape and fuller coverage for a polished, hotel-style finish.
Are queen and full duvet covers interchangeable with respect to mattress size?
Some brands, like us, offer “Full/Queen” covers, which fit both. Beddley offers precision “Full/Queen” covers, thoughtfully designed to fit both full and queen mattresses beautifully. The sizing ensures a perfect fit — with no bunching, slipping, or excess fabric.
Many shoppers also choose queen-sized duvets for a fuller, hotel-style drape on a standard queen bed.
Are you looking for an oversized King duvet?
If you prefer a generous, hotel-style drape, choose an oversized King or California King duvet measuring at least 106″ × 94″ or larger. This provides extra length and coverage for deeper mattresses, plush toppers, or anyone who loves that elegant, enveloping look.
What are standard duvet and duvet cover dimensions?
When selecting a duvet and cover, ensure their dimensions are closely matched; check the dimensions carefully to avoid any issues. For example, a queen duvet cover typically measures 90" × 92", while a king cover measures about 106" × 92". A small difference of a few inches is normal - it helps the insert fill out the cover smoothly and prevents bunching or empty corners.
Because Beddley duvet covers are made from 100% cotton, a little extra allowance is intentional; natural cotton may shrink slightly after the first few washes for a perfect fit over time.
Should a duvet cover be bigger than the duvet insert?
Your duvet cover and insert should be close in size — a small difference of a few inches is perfectly fine and helps create a soft, full finish; always check the dimensions to ensure a proper fit.
Because Beddley duvet covers are 100% cotton, a touch of ease is built in; natural cotton may shrink slightly after the first few washes, ensuring a beautifully tailored fit over time.
Every Beddley Easy-Change® cover includes secure inner ties and our patented zipper system to keep your duvet perfectly in place.
How do I keep my duvet insert from shifting?
Use corner ties or choose a Beddley Easy-Change® duvet cover with secure inner ties and a three-sided zipper that keeps your insert perfectly in place — so your bed always looks crisp and beautifully made.
Can I machine wash and care for my duvet cover?
Absolutely. All Beddley Easy-Change® duvet covers are machine washable. Just unzip, remove the insert, and wash in cold or warm water on a gentle cycle with mild detergent.
Tumble dry low and remove promptly while still slightly damp - don’t allow it to become bone-dry - then lay flat and smooth out any wrinkles gently with your palms or fingers. This keeps the cotton fibers relaxed and wrinkle-resistant without ironing.
For detailed washing instructions, see our full guide on how to wash a duvet cover to keep your bedding fresh, soft, and long-lasting.
All Beddley duvet covers are made from OEKO-TEX® certified cotton, ensuring safety, softness, and long-lasting quality wash after wash.
💡 Pro Tip: Rotate between two duvet covers to keep your bed looking fresh year-round while extending the life of each piece.
Use our duvet size chart above to confirm proper fit before laundering or replacing your insert.
What size duvet should I get for my mattress?
Choose a duvet that matches your mattress size - Twin, Full, Queen, King, or California King - for the most balanced fit.
If you love a hotel-style look with extra drape, consider sizing up one category (for example, a King duvet on a Queen bed).
Deeper mattresses or toppers may also benefit from a slightly larger duvet for better coverage and warmth.
You can also refer to our duvet size chart above for quick measurements and easy comparison.
Tip: Use Beddley’s Duvet Size Chart above as your quick reference for the perfect balance of proportion and comfort.
How do I choose between a down comforter and a duvet?
Both duvets and comforters provide warmth, but duvets paired with covers offer more flexibility and easier care.
If you like switching styles or prefer effortless maintenance, a duvet with Beddley’s Easy-Change® design is the smarter, time-saving choice.
Is there a difference between a duvet and a comforter?
Yes. A duvet is a filled insert that goes inside a removable cover, while a comforter is quilted and used on its own; both come in various sizes and dimensions to fit your bed.
Duvets are easier to clean and refresh - especially with Beddley’s Easy-Change® three-sided zipper design, which makes bed-making up to 10× faster.
