What Size Rug for a Living Room

An 8×10 rug suits a medium living room and a 9×12 a large one (Wayfair). Under a seating group, the rug should reach at least 6 in past each end of the sofa: an 8×10 leaves 18 in beside a 7-foot sofa.

The rule

  • The rug extends at least 6 inches past each side of the sofa (Wayfair).
  • For a seating area, add 12 to 24 inches to its length and width (Wayfair).
  • For a whole room, subtract 6 inches from the room's length and width (Wayfair).
