What size rug should I use for my living room sofa placement?

The best rug size for living room sofas depends on room and furniture dimensions. For example, a nine by twelve-foot rug centers seating in a twelve by sixteen-foot room, holding front legs of sofas and chairs. This anchors the zone, improves flow, and adds cohesion. The rug should be large enough to unify the seating arrangement without overwhelming the space, enhancing visual appeal and comfort for any sofa size.
