Jun 19, 2025 by Staff The Rug Decor

A cozy king-size bed naturally contours to your body shape, assuring a good night’s sleep. But then you wake up in the morning, and your feet touch the floor. In that moment, you realize you could use a soft rug to cushion your feet from the cold and hard surface. But, like many others, you may ask the same question: “What size rug should I get for a king bed?” The answer lies in this detailed blog.

Before You Choose a Rug for King Bed, Know This Golden Rule

When you shop for a rug for a king-size bed, ensure it’s wide enough to extend on all sides of the bed. This way, every time you wake up, the first thing your feet touch is the soft and warm texture of the rug instead of the cold floor.

Recommended Rug Sizes for King Beds

The following are the rug sizes that can match your king bed and room.

6’x9’ Rug

A rug of this size works perfectly well in a smaller room. The 6’x9’ rug offers a snug under fit, with only a small margin protruding out on all four sides. Only when you look closely, you realize how it delivers design and function from the shadows.

8’x10’ Rug

Thinking of balancing between coverage and function? An 8’x10’ rug is the most popular size and is commonly used with king beds in a medium-to-large room. There’s ample space to step onto the soft rug when you get out of bed, while leaving enough room to expose the flooring.

Expert Advice: These rug dimensions are also best suited for small rooms.

9’x12’ Rug

This 9x12 rug provides full coverage to a large room. It fits well under a king bed, sized 76"x80". It is also big enough to extend further on each side to accommodate furniture like nightstands and benches. You can purchase any rug of this size for your bedroom, then lay it down to create a soft, visually appealing, and spacious room.

12’x15’ Rug

A large king bed for your master bedroom requires an area rug of size 12’x15’ to provide maximum coverage. It can encompass everything, including nightstands, a bench, and a bed frame. Our experts recommend this rug as the best fit for a California king-size bed, since it’s slightly larger than a standard king bed.

  • It is budget-friendly.

  • Use a 6'x9' rug for the two-thirds rug placement under your bed.

  • Less floor protection and sound insulation.

Runner Rugs

  • To be placed only on either side of the bed.

Common Mistakes to Avoid When Sizing Rugs for King Beds

Selecting a rug for your king bed may seem easy, but in hindsight, there are many factors to consider before making a purchase. Get the right rug size for your king bed by avoiding these common mistakes.

Choosing a Rug That’s Too Small

A rug that’s too small could distort the room’s balance, even cramp it up. The best size area rug for a king bed is one that matches the bed’s size. The safest size to choose is a 9’x12’ rug, but you could even go a size up, depending on the size of the room.

Ignoring the Room’s Layout and Entryways

If you focus only on getting a rug size to match the king bed, it might be too large for the surrounding area. Pick a size that does not block doorways. But not one too small that it seems insignificant in a large area.

Not Using a Rug Pad

The rug by itself may slip around a lot and wear out sooner, which will require spending on a replacement. Solve this problem by placing a slip-resistant rug pad under the rug to prevent it from sliding or causing a trip hazard.

Best Rug Styles & Patterns to Match Your King Bed and Other Décor

In addition to learning about what rug size to place under the area of the king bed, also consider its style and pattern. Knowing how to pick a rug color will help match the bed and the elements around it.

Solid Neutrals for Minimalist Rooms

f you’ve taken a minimalist approach in bedroom design, go with neutral colored rugs. Beige or brown shades can match the warmth of the room and define the space. These colors maintain simplicity while enhancing comfort and visual harmony.

Geometric or Persian Patterns for Character

If a floor space seems empty, use a geometric rug to give it a modern and bold character. Else, you can even pick from Persian patterns to introduce historical intricacies, depth, and warmth to your bedroom.
