Duvet Cover Sizes and Dimensions (With Chart)
Written by Nicole Pyles
Key Takeaways:
-
- Choose a duvet cover that is equal to or two inches smaller than your insert to achieve a plush, hotel-style look without excess shifting or fabric sag.
- Deep or oversized mattresses require sizing up or calculating dimensions with specific inch measurements to ensure sufficient overhang on all sides.
- Inner corner ties paired with practical button or zipper closures keep the insert firmly anchored inside the cover for consistent warmth and easier laundering.
For a quick bedroom makeover, whether to match the season or align with your new style, consider a duvet cover.
This versatile bedding option slips over your duvet insert (often filled with down, feathers, or cotton) much like a pillowcase covers your pillow.
A duvet cover lets you easily change the fabric, color, and theme of your bedroom without having to swap and store away heavy comforters.
However, it’s important to choose the right size duvet cover. The wrong fitting option can cause uncomfortable bunching, leaving your bed looking lumpy instead of inviting.
We’ve created a guide to help you find the correct duvet cover size for your mattress so you can feels and create the most cozy and comfortable bed possible.
Standard duvet cover dimensions chart by bed size
There are many factors to consider when choosing the ideal duvet cover size. But primarily, it’s about how much of your duvet you want to hang over the sides of your bed.
Here are the recommended duvet cover sizes based on your mattress size:
| Mattress Size | Mattress Dimensions (in) | Duvet Cover Dimensions (in) |
| Twin | 38 x 75 in | 74 x 98 in |
| Twin XL | 38 x 80 in | 74 x 98 in |
| Full | 54 x 75 in | 95 x 98 in |
| Queen | 60 x 80 in | 95 x 98 in |
| King | 76 x 80 in | 98 x 111 in |
| California king | 72 x 84 in | 98 x 111 in |
Why duvet cover and insert sizes don’t always match exactly
Choosing a new duvet cover to match your insert can be a puzzling challenge. Duvet inserts and covers often come in different sizes as there aren’t universal size guidelines for this type of bedding.
Use a tape measure to determine your insert’s size rather than relying on generic mattress sizing. This helps you avoid buying a duvet cover that’s too big for your insert, which can result in a baggy, flat look.
You also want to avoid buying a duvet cover that’s too small as it can look bunchy and ill-fitting. Ideally, opt for a duvet cover that’s the same size as your insert or a couple of inches smaller.
The 2-inch rule for a fluffy, full duvet ;ook
If you’ve ever stayed at a hotel and wondered how they managed to achieve that luxurious, fluffy look, it’s due to a specific sizing trick.
Choose a duvet cover that’s 2 inches smaller in both width and length than the insert. This will create a full, fluffy appearance that won’t shift or bunch up while you sleep. You’ll also avoid cold pockets caused by excess duvet cover fabric.
How to choose a duvet cover for oversized or deep mattresses
If you have a pillow top or oversized mattress, such as a California king or larger, an ill-fitting duvet cover can make the duvet look too small or lead to a nightly battle for the covers between you and your bed partner.
An appropriately sized duvet cover (and insert, if you don’t have one already) provides generous overhang. A good rule of thumb is to go up a size from your mattress to ensure enough coverage on all three sides. Be sure to consider your existing duvet insert size as well.
To determine the ideal measurements, we recommend:
- If you already have one, measure your insert to determine the ideal width and length for your cover.
- Choose a cover that’s at least the same size, if not an inch or two smaller, than the insert.
- Measure your mattress depth for the cover and the insert width. You want a cover and insert that are at least 8 to 12 inches wider and longer than the mattress or more, depending on your preference.
- Don’t rely on mattress size labels when making your purchase; use specific inch measurements instead.
Corner ties and closure types (buttons, zippers, ties)
A duvet cover won’t stay in place on its own. The best type of duvet cover is one that features inner corner ties. These ties attach to all four corners of the duvet insert, keeping it in place throughout the night. Without it, your duvet insert could bunch up, causing your bedding to look flat or misshapen.
There are also different closure type options available for your duvet cover. These closures secure the duvet insert inside so it doesn’t shift off the cover while you sleep.
- Button: Button closures are the most practical option as they’re discreet and easy to replace if one falls off. Plus, it’s easier to open the duvet and remove the cover for washing on laundry day.
- Zipper: A zipper closure keeps the insert securely inside, but it has a few drawbacks. The zipper can snag the fabric and can be difficult to replace if it breaks.
- Ties: Exterior tie closures use ribbons to fasten the duvet cover closed. It looks more decorative than other styles, but it can come loose and be less convenient overall.
The ideal closure type depends on your overall aesthetic and upkeep preferences. Simplest is often better when deciding on the closure type.
Maintenance and care for fabric duvet covers
The biggest benefit of a duvet cover is that it’s interchangeable and won’t wear out your insert. That does mean your cover will need regular washing and ongoing maintenance to ensure it lasts.
Here are a few guidelines to follow:
- Refer to care labels: Fabric, color, and texture can all impact your laundry routine with your duvet cover. Follow any guidelines included with your duvet cover, such as water temperature, handwashing vs. machine washing, and drying instructions.
- Use gentle laundry detergent: Harsh laundry soap can erode the quality of your duvet cover. Use a gentle, bleach-free detergent during a laundry cycle.
- Air dry when possible: Drying the cover can also affect fabric quality. If possible, air-dry it for the gentlest cleaning.
- Minimize wash frequency: Washing your duvet cover too often can fade the color and degrade the fabric quality. Unless there’s a major mishap, wash your duvet cover every few weeks.
- Store properly: One of the biggest perks of a duvet cover is swapping it out for a changing mood, season, or style. When storing covers for extended periods, place them in breathable storage bags to prevent moisture buildup. Clean and dry before storing.
- Address stains: Don’t let stains or spills linger on the fabric. Spot clean as they happen using mild soap and a soft cloth. Avoid harsh scrubbing to avoid damaging the fabric.
FAQs
Should a duvet cover be the same size as the duvet insert?
Your duvet cover should be the same size as, or a couple of inches smaller than, the insert. This gives your duvet a fluffy, cozy look while providing enough warmth and coverage for you at night. It’s the same technique that designers and hotels use to make the bed look inviting.
How much larger should a duvet insert be than its cover for a fluffy look?
The insert should be one or two inches larger than the cover to achieve that fluffy appearance. This ensures you don’t have any loose fabric or excessive shifting while you sleep.
What duvet size works best for a deep mattress?
Choose a larger size duvet if you have a deep mattress. The extra length will give you enough overhang so you don’t have to battle the covers while you sleep. Measure your depth before choosing the duvet cover to ensure the right size.
