Common Questions
Frequently Asked Questions
What size rug do I need for a living room?
For a living room, the rug should be large enough that all front legs of seating furniture rest on it. A 12x16 room typically needs an 8x10 or 9x12 rug. The key rule: leave 12-18 inches of bare floor between the rug edge and the walls.
How big should a rug be under a dining table?
A dining room rug should extend at least 24 inches beyond all sides of the table so chairs remain on the rug when pulled out. For a 6-person table (roughly 36x72 inches), you need at least a 7x10 rug. For an 8-person table, go with 8x10 or 9x12.
What size rug goes under a queen bed?
For a queen bed, use an 8x10 rug placed so it extends about 2 feet on each side and at the foot. Alternatively, two 2x3 or 3x5 runners on each side work well. The rug should extend at least 18 inches beyond each side of the bed.
Should a rug go under furniture or in front of it?
In living rooms, place at least the front legs of sofas and chairs on the rug. This visually anchors the seating area. In bedrooms, the rug typically goes under the lower two-thirds of the bed. A rug that floats in the middle of a room with no furniture on it looks disconnected.
What are the most common rug sizes?
Standard rug sizes include 5x7, 6x9, 8x10, 9x12, and 10x14. For runners, common sizes are 2x6, 2x8, and 2x10. Round rugs come in 4, 6, and 8-foot diameters. When between sizes, always go larger.
How much floor should show around a rug?
Leave 12-18 inches of bare floor between the rug edge and walls in standard rooms. In smaller rooms, 8-12 inches works. In large open-concept spaces, you can leave up to 24 inches. Consistent spacing on all sides creates a balanced look.
