Rugs over 11 feet in length are often referred to as palace size rugs or mansion size rugs. Extra large rugs of this size are made for large living and entertaining spaces or large master bedrooms. A mansion rug by the nature of its size should have the proper design and color necessary to tie together a large room and its furniture and furnishings. An extra large area rug is the one component that can bring together the various elements of a very large room into a unified and cohesive space.
