What size area rug best anchors living room furniture arrangements?

An area rug approximately nine by twelve feet often best anchors typical living room furniture arrangements. This size allows all main seating pieces to sit at least partially on the rug, unifying the floor plan visually. It defines gathering areas and adds warmth without overwhelming space. When choosing your rug size, measure seating zones ensuring the rug extends beyond furniture edges by at least twelve to eighteen inches. Oversized rugs also introduce texture and soften hard surfaces, making neutral spaces feel cozy and balanced.
