Can I Use King-Size Bedding on a Queen Bed?

While it seems like the obvious choice to order the same size blanket as your mattress, there are many reasons to use a king comforter on a queen bed. Maybe you’re trying to make use of an heirloom quilt, you like the coziness of oversized bedding or the blue duvet in the perfect shade only comes in king.

Whatever the reason, putting a king-size blanket on a queen bed can be a decorating triumph or a design faux pas depending on what you want to achieve. Familiarizing yourself with the standard sizes of bedcoverings and how they affect the look of a bed can help you decide what’s best for your space.



Queen vs. King Sizing

While mattress dimensions are fairly consistent, bedding in the same size can vary more than 10 inches in length and width by brand. One king comforter may fit on a queen bed, while another pools on the floor. Checking the bedding measurements against your mattress will help you select the ideal size.

Measuring the Mattress

In general, a queen mattress is 60 inches wide by 80 inches long, and a king mattress is 76 to 78 inches wide by 80 inches long. Mattress height ranges from a trim 6 inches all the way up to 18 inches for plush luxury brands. This difference in height can impact how your bedding fits.

Taller-than-average mattresses require more fabric to reach across the top and down the edges, so your blanket may seem a little short on the sides if it’s on the smaller end of queen sizing. To complement an ultra-plush queen mattress, consider using a larger queen comforter or smaller king bedding on a queen bed.

Checking Comforter Sizing

Noting the dimensions before you buy is key for any kind of bedding, but especially for fluffy blankets. The thick filling of a down duvet or puffy comforter tends to pull at the fabric, resulting in less coverage on the bed. In this case, a king-size quilt on a queen bed may be just what you need.

When shopping online, product specifications usually indicate the exact dimensions of the comforter. When shopping in a store, look at product labeling for the measurements.

How Does a King-Size Comforter Look on a Queen Bed?

Let’s assume, though, that you have a standard height queen mattress and bedding in an average king size. How would that look? The answer may be different based on your decor preferences.

A king bed is the same length as a queen bed but about 20 inches wider. Since comforters should hang an equal distance from the ground on three sides, this can present an issue when sizing up to king bedding. A king comforter on a queen bed will fall close to the floor on the sides, but only a little below the mattress at the foot of the bed.

Should that stop you from using a king blanket on a queen bed? It’s really up to your tastes and your existing furniture. If your bed has a footboard or if you have a storage bench placed at the foot of the bed, a queen and king comforter may look fairly similar. Without anything at the foot of the bed, a difference in proportions will be more obvious between the two sizes.



What Is the Proper Length for Each Type of Bedding?

Whether you should use a king-size comforter on a queen bed may also depend on how much you care about design maxims. Decorators follow certain rules for sizing to create classically well-dressed beds. Sizing up for some bed linens may throw off these proportions, affecting aesthetics and comfort.

Many bedcoverings fall at different distances from the floor. If you want to recreate the balanced, layered look you find in luxury hotels or decor magazines, knowing the suggested length for each type of blanket may help you pick between a queen or king size.


A standard duvet includes a removable case and a soft insert. Duvets usually measure on the larger side of queen or king sizing. You can lay one over a quilt, fold it at the end of the bed, or pull it up to cover the pillows. A duvet should hang down the sides and foot of the bed to cover the box spring.

The problem with putting a king duvet on a queen bed is that it may touch the floor on the sides. Thicker blankets like duvets draw the eye downward if they puddle on the ground. For fluffy bedding that seems light and airy, choose a duvet long enough to drape over the sides of the bed but short enough to avoid weighing it down visually.


Another option for the top layer of bedding, a comforter features filling sewn inside a fabric case. The edges should hit either just below the mattress for a more sleek look, or cover around two-thirds of the foundation for a fuller, high-loft design.

If you opt for a heavyweight style, a king comforter might be too big for a queen-size bed. Extra weight on the sides of a thick comforter tends to cause the filler to mat, which affects the warmth of the blanket. It’s a good idea to stick to lighter styles with smaller dimensions if you use a king comforter on a queen bed.


Coverlets are soft, lightweight bedcoverings with sides that fall a few inches past the box spring. They work as an inner layer over the flat sheet but under your main blanket. The edges of a king coverlet on a queen bed might peek out under the comforter, so you would need to tuck them under the mattress.


This large, decorative blanket should rest over the pillows and touch the floor on three sides. Although it’s less common to find bedspreads in contemporary decor, many vintage and heirloom quilts showcase this cut. Because it’s already oversized, a king bedspread on a queen bed is probably too big.


Quilts are a middle-weight, medium-sized bedcovering that can function as the outer layer of your bed or a bonus blanket underneath a comforter or duvet. These bed linens feature batting sandwiched between two layers of material and stitched in elaborate designs.

These blankets typically come in a more modern coverlet size that hits just below the top of the box spring or a classic bedspread style that kisses the floor. A coverlet king quilt on a queen bed might reach to the ground like a bedspread, giving your space a fun, retro vibe.

What Size Comforter is Best for a Queen Bed?

The two most common bedding sizes for a queen bed are queen and king. Which works for you depends on several factors, from mattress height and blanket type to personal preferences about the look and feel of your bed. Once you know all the elements involved, you can decide whether putting a king-size duvet on your queen bed is the right call.
