We'll answer the important question, "What size rug is best for a king bed?" in this guide.

We will break down the sizes, layout options, and room sizes, and give you expert advice on how to get a look that looks like it was designed by a professional, so you don't have to guess.

 

Why Rug Size Matters Under a King Bed

The rug under a king-sized bed is useful in more than one way. 
It defines the space, keeps the furniture in place, cushions hard floors, and makes getting in and out of bed more comfortable. 

But if you choose the wrong rug size, even a fancy bedroom can feel awkward or missing something.

King-size beds are usually 76" x 80", which means that any rug that goes with them should go past the bed frame by at least 18 to 24 inches on each side and at the foot.  This makes sure that everything works and looks good.
