To determine the right size rug for a queen bed, a general rule of thumb is that the rug should extend 18 to 24 inches beyond the edges of the bed. A standard queen bed is 60 inches wide and 80 inches long, so the rug should be at least 8-9 feet wide and 8-9 feet long to provide the ideal coverage. For a larger area rug, a size of 8 by 10 feet or 9 by 12 feet is recommended to accommodate the queen bed and nightstands
