What Size Rug for a Living Room?

• 8 by 10 feet is the smallest rug that works for a standard living room seating group.
• 9 by 12 feet is the sweet spot when the room is large enough for it.
• 10 by 14 feet or larger suits big or open-plan rooms.
• At minimum, the front legs of every seat in the group sit on the rug. All four legs on the rug is the most formal look.

Measure your sofa first. The rug should extend 6 to 12 inches past each end of the sofa, and you should lean toward 12 inches when the room allows it. A 90 inch sofa therefore wants a rug at least 102 to 114 inches wide, which is why a 5 by 8 foot rug (60 inches wide) never works under a full-size sofa.

Then look at the depth. The rug should reach from in front of the coffee table back under the front legs of the sofa, and far enough sideways to catch the front legs of any chairs in the group.

• All legs on: every piece of seating sits fully on the rug. Most formal, and it needs the biggest rug, often 9 by 12 or larger.
• Front legs on: the front legs of the sofa and chairs sit on the rug and the back legs sit off. This is the most common and most practical choice, and it works with an 8 by 10.
• Floating coffee table group: only the coffee table sits on the rug and the seating stays off. Avoid this. The rug looks like a small island and the room feels disconnected.

A rug should not run wall to wall. Leave roughly 12 to 18 inches of visible floor around the edges in a typical room, and a little more in a large room. That border frames the rug and keeps it from looking like cheap carpet. If your room is so small that the rug would fill the whole floor, go down one size and keep the front-legs-on rule.

• 5 by 8: too small for nearly any living room seating group. Use it in an entry or under a single chair.
• 8 by 10: the minimum for a standard living room. Works with a sofa up to about 84 inches and a pair of chairs, front legs on.
• 9 by 12: the best fit for most rooms with an 84 to 96 inch sofa and chairs. Gives you the overhang you want on both sides.
• 10 by 14 and up: for large rooms, sectionals, or open layouts where one rug has to anchor a big zone.

• Buying for the coffee table. The coffee table is not the reference. The seating is.
• Choosing a rug that stops short of the sofa legs, so the sofa looks like it is sliding off.
• Skipping a rug pad. Always use one: natural rubber on hard floors, or felt plus rubber for a softer feel. It stops sliding and protects the floor.
• Matching a rug in open-plan rooms to the whole space. Give each zone its own rug, compatible but distinct, with floor between them acting as a corridor.
• Ignoring pattern scale. A large-scale rug pattern with medium-scale pillows reads layered. Two large patterns at the same scale reads as chaos.

Treat the whole sectional as one piece. The rug should reach under the front legs of both the long side and the chaise or return, which usually means 9 by 12 or larger. A rug that only covers one arm of an L leaves the other half hanging in the air.
