8x10 vs 9x12: Which Rug Size for a Living Room?

In most living rooms the sofa decides it. An 8 by 10 suits a sofa up to 8 feet long in a room of roughly 11 by 13 feet. A 9 by 12 is the better choice once the sofa is longer than 8 feet or the room is 12 by 15 or larger. It is also the one to pick if you want the whole sofa on the rug. If the room takes either, the bigger rug usually looks better.^[1]

How big is an 8x10 rug, and a 9x12?

An 8x10 rug is 8 feet wide and 10 feet long. That is 96 by 120 inches, about 244 by 305 cm, and 80 square feet of floor. A 9x12 is 9 by 12 feet: 108 by 144 inches, about 274 by 366 cm, and 108 square feet. So a 9x12 is a foot wider and two feet longer, and it covers about a third more floor.

Both are room-size rugs. An 8x10 is the size most living rooms are planned around, and in a bedroom it is the smallest rug that goes under a whole queen bed. A 9x12 suits a larger living room, or a king bed with both nightstands. Our guides to a queen bed and a king bed give the bedroom numbers, and rug sizes in centimeters converts other sizes. The rest of this guide is about the living room.

Start with the length of the sofa

The rug should run past each end of the sofa by at least 6 inches, and a foot looks settled. A rug that stops short of the sofa arms makes the sofa look too big for the room, even when it is not.

Lay an 8 by 10 with its 10-foot side along the sofa and you have 120 inches to work with. An 84-inch sofa leaves 18 inches of rug at each end, which is generous. A 96-inch sofa leaves 12 inches, which is still right. Once the sofa is longer than 8 feet, the margin drops under a foot and the rug starts to look too small.

A 9 by 12 gives you 144 inches along the sofa. The same 96-inch sofa now has 2 feet of rug at each end, and a 10-foot sofa still has a foot. If there is a chair or a side table at each end of the sofa, count them as part of its length. The rug should reach the front legs of those chairs too.

Then check the depth of the seating group

The second number is how far the rug reaches into the room from the sofa. In a typical room, the coffee table sits 14 to 18 inches from the sofa and is 20 to 24 inches deep. The chairs opposite sit another 14 to 18 inches beyond it. So the front of the sofa and the front of those chairs are about 4½ feet apart.

An 8 by 10 is 8 feet deep. Tuck it about 6 inches under the front legs of the sofa. In most rooms it then reaches far enough for the chairs opposite to stand on it with all four legs. What it cannot do is hold the whole sofa as well. A sofa is about 3 feet deep, so the rug left in front of it covers the coffee table and leaves little or nothing for the chairs.

A 9 by 12 is 9 feet deep, and that extra foot changes the layout. The whole sofa can stand on the rug, and the front legs of the chairs opposite still land on it. That layout makes a living room feel finished, and it is the main reason to size up.

Brick loft at dusk, a red Tabriz rug with cream corners under a round walnut table, a tan leather sofa and two cognac leather armchairs — The front legs of both armchairs land on the rug and the coffee table sits in the middle of it, but the sofa stops just short of the far edge. A deeper rug, such as a 9 by 12, would bring the sofa onto it as well.

Check the room size and the walkways

Leave a border of bare floor between the rug and the walls. Aim for at least 8 inches in a small room and 12 to 18 inches where there is space.^[2] That makes the comfortable room size for an 8 by 10 about 11 by 13 feet, with 10 by 12 as the tight minimum. A 9 by 12 wants about 12 by 15, with 11 by 14 as the minimum. A room of around 12 by 14 takes either, and then the sofa and the depth of the group decide.

Then walk the room. Main paths need 30 to 36 inches of width, and the edge of a rug should not run down the middle of one. When one foot is on the rug and one is on the floor, toes catch and the border wears in a line. In many rooms the path from the door to the kitchen passes the seating. Keep that path clear of the rug, or bring the rug far enough out that the path lies on it. That second option is often why a 9 by 12 works in a room that looked too small for it.

Check the doors while you are there. Almost all of our rugs are low pile, so a door that opens into the room usually clears them. A pad adds height, though, so swing the door over the spot before you decide.^[3]

Vintage rugs are rarely exactly 8 by 10 or 9 by 12

Hand-knotted rugs were woven one at a time on whatever loom the weaver had. The size in feet is a label added later, and very few vintage rugs measure within a few inches of 8 by 10 or 9 by 12. What you find instead are their neighbors.

7 by 10. As long as an 8 by 10 but narrower, and many are closer to 6 feet 10 inches wide.
8 by 11 and 8 by 12. The real vintage stand-in for an 8 by 10, with an extra foot or two along the sofa. That length helps with a longer sofa, or a sofa with a side table at each end.
9 by 13. The vintage 9 by 12. The extra length rarely hurts in a room big enough for the width.
10 by 13. A foot more in both directions, for rooms of about 13 by 16 and larger, or for two sofas facing each other.

Cream and brown Turkish rug on dark parquet in a narrow apartment living room with an olive sofa, oak coffee table and two cream armchairs — A Turkish Isparta, 6 feet 8 inches by 10 feet, sold as a 7 by 10. It is as long as an 8 by 10 but narrower, which can decide whether the chairs opposite stand on the rug or beside it.

The 7 by 10 is the one to watch. In a photograph it looks just like an 8 by 10, but a foot or more of depth is missing. In a room around 10 feet wide, that makes it the right rug. In a room that needed an 8 by 10, it leaves the chairs on bare floor.

Going up a size also costs less than people expect. From 8 by 11 upward, most vintage rugs cost between $1,500 and $3,000, so a 9 by 13 is rarely much more than an 8 by 11. If the room takes the bigger rug, price is seldom a reason to hold back.

Measure the rug, not the label

Size collections, ours included, group rugs by the nearest foot. Two rugs in the same 8 by 11 collection can differ by up to a foot in width. Even 6 inches matters when you are working out whether the chairs land on the rug. So do the sums above with the measured size, which every listing gives in feet, inches and centimeters.

The quickest check needs painter’s tape. Mark the rug’s real outline on the floor and leave it down for a day.^[4] Our guide to choosing the right rug size goes through that method for every room. The tape also shows you something numbers do not: how much bare floor you like to see.

8x10 or 9x12: a quick way to decide

Choose an 8 by 10, or a vintage 8 by 11 or 7 by 10, when:

The room is under about 12 feet wide.
The sofa is 8 feet long or less.
You want only the front legs on the rug, or a piece of furniture along one wall should stay off it.^[4] A TV stand is one example, covered in should a rug go under the TV stand.

Choose a 9 by 12, or a vintage 9 by 13 or 10 by 13, when:

The sofa is longer than 8 feet, or it is a sectional.
The room is about 12 by 15 or larger.
You want the whole sofa on the rug.^[2]
A main path would otherwise run along the rug’s edge.

Georgian drawing room with gray-green paneling and a marble fireplace, a camel velvet sofa standing fully on a deep red Sabzevar rug, green armchairs — A Sabzevar, 9 feet 1 inch by 12 feet, one of the few vintage rugs that really is a 9 by 12. Nine feet of depth takes a whole sofa and the front legs of the chairs across from it.

A sectional needs the rug to work along two sides at once, and we cover that in a rug under a sectional. If the living room shares its floor with a dining table, read placing a rug in an open-plan living space. The same two sizes come up in the bedroom, where the bed sets the numbers instead of the sofa. Our guides to a queen bed and a king bed have them.

When you have your size, start with the living room rugs or go straight to the size collections above. The size guide has the full conversion table if you think in centimeters.
