What Size Rug for King Bed

What Size Rug for King Bed?

You can use a rug to perfectly tip up all the furniture and accessories in the bedroom. If you’re going with the super-sized king bed, you need to be careful with the rug size you’re going to use. Anything too big might be overwhelming, but if you go with a smaller one, it may seem out of place compared to the royal dimensions of the king bed.

A general rule of thumb says that the carpet should extend approximately 18 to 24 inches to the sides. As for the length, you only need to worry about extending the rug beyond the foot area of the bed, as the headrest is probably positioned against the wall. In general, you should extend the rug 18 to 24 inches to the front.

To summarize the initial calculations, you should extend the rug 18 to 24 inches to each side, excluding the one with the headrest.

Decide on the specific length that will work best for you, depending on the foot area you have available to play around with. If you have a larger room with a generous amount of floor space, go with the upper limit of 24 inches. If you don’t have much room to spare, you can go with 18 inches on each side.

The minimum size for a rug underneath a king-size bed

A standard king-size bed measures 76 inches wide and 80 inches long. If you add the extra 18 inches to the sides, you’ll end up with a minimum size of 112 x 98 inches. However, you still have some room to tweak the dimensions if you decide to play around with the positioning of the rug. 

If you want to buy a smaller rug, you can narrow down the length of the rug by positioning it further away from the headrest. For the best visual appearance of a smaller rug, consider distancing the rug from the nightstands, and you’ll get a perfectly round-up look that will tie up the bed, the nightstands, and the rug in amazing balance.

The maximum size for a rug underneath a king-size bed

There really isn’t a particular limit about the maximum size rug you can use in the bedroom, as long as you blend it in with the rest of the furniture. You can even go a little crazy and extend the rug past 24 inches from the sides. Going past the 24 inches will make for an even cozier experience in the bedroom, as you’ll be able to walk barefoot freely, even if your floors are tiled.

A bigger rug can add luxury to the room, but you should always follow some specifics. For instance, you don’t want your carpet to go under the closet or end halfway under the dresser. When calculating the carpet’s dimension, consider all other furniture that revolves around the king bed, or you might make a big design error.

Small to medium-sized rooms

If you have a king-size bed in a smaller room, you should go with the smallest rug size and get an 8 by 10-foot rug. This particular rug size can easily accommodate the entire bed frame, but the nightstands will have to stay off unless you have some smaller ones. You can make a smaller rug seem larger by placing the headboard and the nightstands on the bare floor.

Large rooms

If you have more room to display the artistic rug and make a statement, you should definitely go with a 9 by 12-foot rug in a larger bedroom. The king-size bed frame and both nightstands can easily fit on top of the rug, and you can even snug on the bench. A 9 by 12-foot rug will make your bedroom feel more airy and spacious.

California king-size beds

A standard king-size bed measures 76 by 80 inches. However, if you have a California king-size bed, it might be slightly narrower but longer, measuring 72 inches wide by 84 inches long.

Therefore, you can easily go crazy with the rug size and go up to a 12 by 15-foot rug that will comfortably fit your bed, nightstands, and bench and still leave enough room for people to admire the rug design.

What Should Go on Top of the Rug?

When considering the perfect size for a rug underneath your king-size bed, you’ll need to decide what you’re going to put on top of it. Despite limiting the rug to the bed area and 18 to 24 inches to the side, you can also place some other furniture on top of your new rug. Here are some of the combinations you can make:

If you have matching nightstands and a bedside bench, you should also consider placing them on top of the rug. A suitable carpet can be a great way to round up the already well-thought-out set of furniture you have.

Place two-thirds of the bed and the entire bench on the rug, leaving the headboard and the nightstands on the bare floor. If you want to save some money on the carpet size, or the carpet you’ve set your eyes on doesn’t come in a larger size, you can leave out the headboard and the nightstands of the rug, creating an intriguing design that will look amazing and perfectly put together.

If you’re working with a larger room and don’t have a problem with cold floors, you can drag the rug away from the headboard and showcase it as the room’s centerpiece. Place only the lower third of the bed and the bench on top of the rug, and set the rest of the rug out for display.

Positioning Tips

Although the bed size has the main word when considering rug dimensions, there are other things you should account for when deciding the rug size. Other pieces of furniture also need to be considered if you want to enhance functionality without compensating for appearance. Therefore, we have some positioning tips to help you find the perfect rug size and transform your bedroom.

Rug positioning relative to the doors

When picking out the right size and position of the area rug underneath your king-size bed, you should always make sure you have enough clearance for the doors. The doors should be able to open and shut freely without getting stuck in the area rug.

Rug positioning relative to the dresser

Depending on your preference, the dresser can go on top of the area rug or the floor. However, dressers are typically placed away from the area rug. Whether you put the dresser on top of the rug or away from it, ensure there is enough clearance for the drawers to open freely.


Always insist on symmetrical positioning and sizing of the area rug. Symmetry can help you blend in the rug perfectly, but if you offset it, it can easily go from perfectly placed to misplaced.

Therefore, try to be as symmetrical as possible. If you’ve added 18 inches to one side of the bed frame, make sure you do the same on the other two sides as well. If you’ve left some room between the carpet and the headrest, try leaving at least that much room between the end of the rug and the opposite wall.

Final Words

If you were wondering what size rug for king bed you need to use in your bedroom – you now have all the information you need to get the perfect carpet. 

Although the generally accepted perfect size for a carpet underneath a king-size bed is 9 feet by 12 feet, you can experiment with various sizes based on the floor space you have. The best way to determine the perfect rug size is to visualize your carpet in the room. You can use some computer software or stick some tape to outline the carpet size you’re considering, so you’re certain you’ll get the right size.

Despite the size, consider the carpet style and material to find something that will perfectly blend in with your bedroom decor.
