Measure the dining room table and then add 54″ to the length and the width so chairs can be moved in and out without slipping off the rug.
Living Room & Family Room
Measure the perimeter of your entire furniture grouping and deduct 24″ from the length and the width. This will allow the front legs of sofas and chairs to be on the rug and anchor the seating area. If you want to unify and “box in” your arrangement for a more contemporary look, measure so ALL parts of the furniture will be on the rug. In larger rooms where there might be more than one furniture grouping, you may need 2 rugs.
Measure the size of your hallway and subtract 12″ from the length and width. This will allow for a 6″ border of flooring to show all around.
Measure the bed, then add 28”-24″ (12” for twin beds) to each side that is not against the wall. This way you have a rug to stand on while you put on your slippers. Or come off all walls 18” for a “room size” rug.

In irregular-shaped rooms, consider a circular rug. In a room that is long and narrow or otherwise awkwardly shaped, a round rug can be a graceful way of defining a conversation area while still allowing high-traffic parts of the room to remain rug-free.

Standard rug sizes are:
