An oversized area rug is a tapestry meant to anchor an entire room. Rugs longer than 10 feet on both the length and the width are considered oversized. Ample floor coverage naturally makes these rugs stand out even in the most understated patterns and muted colors. Home decorators looking for a complementary piece to go with their existing decor will want to search for an oversized rug with inconspicuous design detailing in neutral or complementary colors. Ambitious interior designers will have fun with the generous canvas oversized area rugs bring to an ordinary room.
