When choosing a rug size for a king bed, it is important to consider the dimensions of your room along with furniture placement. Here are some tips to help you choose the right size rug for your king bed:

• A rule of thumb is that the rug should extend 18 to 24 inches beyond the sides of a king-size bed.
• Keep 10 to 20 inches of bare floor between the sides of the rug and the walls.
• The ideal area rug for a king bed should be around 10 feet wide and eight feet long at a minimum.
• An 8 x 10 rug is considered the minimum rug size for a king-size bed because it has just enough length and width to frame the bed without protruding too much from beneath and around the bed when laid vertically.
• A 9 x 12 rug is considered the best when determining what size rug should go under a king bed because this rug size will accommodate your king-size bed, nightstands, and a bench or chest at the foot of the bed.
• A 12 x 15 rug works best for a California king-size bed.
• If you have a large bedroom, then you might consider a rug of 14’ x 16’ or down to something as small as two 2’ x 9’ runners, depending on the look you’re going for.

Remember that the bed frame, nightstand, and bench should all fully sit on the rug.
