If you’ve recently upgraded to an extra large bed, you’re not alone. In 2025, the demand for custom bedding and more spacious sleep environments is booming. With the rise of oversized king comforters and non-standard mattress sizes, the bedding industry is evolving—and oversized comforter covers are leading the way.
Whether you sleep on a California king, an Alaskan king, or a made-to-measure mattress, finding bedding that actually fits and looks good can be a challenge. That’s where custom duvet covers—especially in oversized dimensions—come in. In this post, we’ll explore why they’re ideal for large beds, how to choose the right size and material, and how to style your space in line with custom bedding trends 2025.
Benefits of Oversized Duvet Covers
Oversized duvet covers offer a blend of practicality and style:
- Generous coverage: They fully drape even the deepest and widest mattresses—no more exposed sides or cold feet.
- Enhanced comfort: Sharing a bed? A larger cover helps prevent nighttime tugging by providing ample fabric for everyone.
- Luxurious finish: Oversized covers help create that plush, inviting, hotel-style bed look that’s trending in 2025.
- Easier styling: Whether tucked or draped, oversized covers make bed-making quicker and neater.
They’re particularly well-suited to modern, minimal spaces where the bed is the main focal point.
How to Choose the Right Size
Choosing the correct size is crucial—especially for non-standard or oversized king comforters.
What is the largest duvet cover size?
Standard options top out at 132″ x 120″ (335 x 305 cm), typically for Alaskan King beds. However, many bedding brands (like ours!) offer custom-made sizes for even larger beds or uniquely shaped mattresses.
What size comforter cover for oversized king comforter?
Most oversized king comforters measure between 110″ x 96″ and 120″ x 110″. Your duvet cover should be slightly larger to allow the comforter to fill it properly without bunching. A good rule of thumb: 2–4 inches extra on all sides.
What about closure types?
Opting for a zipper closure on your duvet cover makes a big difference—especially on oversized items. Unlike button closures, zippers keep the comforter securely in place and simplify bed-making.
How do you put a comforter cover on a king bed?
Use the “burrito method”:
- Turn the cover inside out and spread it on the bed.
- Place the comforter on top, corner to corner.
- Roll them together from the closed to the open end.
- Reach inside the cover, grab the corners, and unroll.
- Close the zipper or buttons and fluff.
This technique works especially well with large bedding where managing bulk can be tricky.
Top Materials for Oversized Duvet Covers
Material matters—especially for large, high-contact items like ψομφορτερ covers:
- Cotton Percale: Lightweight, breathable, and crisp—perfect for warmer climates.
- Cotton Sateen: Silky smooth with a subtle sheen, giving a more luxurious look and feel.
- Linen: Durable, breathable, and naturally textured—one of the top custom bedding trends in 2025.
- Custom blends (e.g., bamboo or Tencel): Sustainable, cool, and ideal for sensitive skin.
When you choose a custom comforter cover, you can often pick not only the size but also the material and even closure style, making it a more personalized solution.
Best Closure Types: Zipper vs. Button
When choosing an oversized duvet cover, don’t overlook the closure type. It may seem like a minor detail, but it can make a big difference in everyday use—especially with extra large beds where adjusting the cover is more cumbersome.
- Zipper closures are the top pick for many in 2025. They’re clean, discreet, and keep your duvet insert securely in place without bunching or shifting. They’re also quick to fasten, making bed-making more efficient.
- Button closures, on the other hand, offer a more traditional look and are easier to replace or repair if damaged. However, they can sometimes leave small gaps or come undone with movement.
For those prioritizing convenience and a modern finish, a zipper closure is often the best option—especially when paired with a fluffy, oversized king comforter or a heavy insert.
Styling Tips for Extra Large Beds
Bigger beds require more thoughtful styling to look balanced in a room. Architectural Digest suggests creating distinct zones within a large bedroom to maintain visual harmony, such as combining a reading nook with layered bedding textures to add depth and coziness. Here are a few tips:
- Layer textures and tones: Combine your oversized duvet with throw blankets, pillow shams, and accent cushions.
- Stick to neutral palettes: Soft whites, beige, sage, and grey add calm and elegance without overwhelming the space.
- Use a bed skirt or platform base: Since oversized bedding won’t always hide the bed frame, make sure the base contributes to the aesthetic.
- Add contrast with texture: Pair smooth sateen covers with chunky knits or velvet accessories to avoid a flat look.
Pro tip: Pair your oversized duvet with a custom fitted sheet for a sleek foundation underneath.
Deep Pocket Sheets: The Perfect Match for Oversized Comforter Covers
When upgrading your bed with an oversized duvet cover, it’s also worth considering deep pocket sheets—especially if your mattress is thicker than average. These fitted sheets are designed to accommodate mattresses up to 15–18 inches deep, ensuring a smooth, secure fit that doesn’t pop off overnight.
Pairing deep pocket fitted sheets with a custom comforter cover creates a balanced look and helps your bedding stay neatly in place, even on extra large beds.
Conclusion
Oversized duvet covers are more than a solution to fit your extra large bed—they’re a design upgrade. With the right size, material, and styling approach, they transform even the biggest mattresses into elegant and cozy centerpieces.
