Frequently asked questions
What size rug do I need for a queen bed?
An 8x10 ft rug is the standard for a queen bed in the under-bed-extension layout, leaving roughly 24 inches of rug visible on each side and 24-36 inches past the foot of the bed. A 6x9 is the workable minimum if the room is tight.
What size rug fits under a king bed?
A 9x12 ft rug is the standard for a king or California king. An 8x10 is the minimum but leaves narrower margins than ideal. For very large bedrooms, a 10x14 reads more generous.
Should the rug go all the way under the bed?
No. Start the rug about one-third of the way down the bed so the bedside tables sit on bare floor. Pulling the rug to the headboard wall hides the rug under furniture and makes the room read cluttered.
What is the rule for using runners instead of one big rug?
Two matching 2.5x8 or 3x8 ft runners work when the floor under the bed is already a nice surface, the bed has built-in storage drawers, or the budget is tight. The runners should match the bed's footboard width and run roughly the length of the bed.
What is the most common bedroom rug mistake?
Buying a 5x7 and shoving it under the foot of a queen or king bed. It shows only 10-12 inches on either side and reads like a placemat. If budget is tight, a plain larger rug almost always beats an ornate smaller one.
Do I need to leave space between the rug and the wall?
Yes — 12 to 24 inches of bare floor between the rug edge and every wall. Pushing the rug to the wall makes the room read smaller and looks like the rug was sized wrong.
