Frequently Asked Questions
An 8×10 rug is the recommended size for a 3-seater sofa, allowing front legs of all seating on the rug with the coffee table centered. A 6×9 is the minimum workable size, while a 9×12 provides full coverage for a designer look.
The most popular approach is 'front legs on'—place the front legs of your sofa and any accent chairs on the rug while back legs remain off. This creates a cohesive look without requiring an oversized rug. For a more luxurious feel, size up so all furniture sits fully on the rug.
Leave 12-18 inches of bare floor between your rug edge and the walls. This creates a visual frame around the rug and makes the room feel larger. Never push a rug right up against the walls unless it's wall-to-wall carpeting.
With a wall-positioned sofa, the rug should extend at least 6 inches under the front of the sofa and have all front legs on it. The rug will extend forward to include your coffee table and any facing seating.
