How to Choose the Right Sofa Size
The sofa is the most important purchase in a living room, and it is also the easiest one to get wrong. A sofa that is too big crowds every path. One that is too small looks like it was left behind by the previous owner.
Here is how to size one with confidence.
Sofa length by room width
Standard categories give you a feel for the numbers: a loveseat is 54 to 72 inches and seats two, a standard sofa is 72 to 96 inches and seats three, and an apartment sofa is 62 to 80 inches.
- Rooms under 12 feet wide: a 72 to 84 inch sofa, and no sectional.
- Rooms 12 to 16 feet wide: an 84 to 96 inch sofa. A standard sectional is possible.
- Rooms over 16 feet wide: a 96 inch or longer sofa, or a large sectional.
The wall rule
A sofa should be no longer than two-thirds of the wall it sits against. On a 12 foot wall, that is 96 inches. Longer than that and the sofa dominates the wall with no room for side tables, a lamp or a doorway.
Check depth and height, not just length
Sit on it before you buy whenever possible. Feet flat on the floor, back supported, and you can stand up without a struggle.
- Seat depth 20 to 22 inches: upright and formal. Good for shorter people.
- Seat depth 22 to 24 inches: comfortable for most people.
- Seat depth 24 to 26 inches: deep lounge. Best for taller people, and hard for shorter people to get out of.
- Seat height 17 to 19 inches is standard. 14 to 16 is low-profile modern and harder to rise from. 20 to 22 is traditional and easiest to stand up from.
Make sure the rest of the room still works
- Coffee table 14 to 18 inches in front of the sofa, about two-thirds the sofa's length.
- 36 inches minimum for main walking paths, more with kids or guests.
- Under 18 inches of clear floor on any side means the sofa is too big.
- Facing seats no more than 8 feet apart, ideally 5 to 7 feet.
- A rug that extends 6 to 12 inches past each end of the sofa.
Sofa versus sectional
Choose a sectional when the room is 16 feet wide or more, you want maximum casual seating, and you plan to stay for several years. Choose a sofa plus chairs if the room is narrower, you like a formal or flexible arrangement, or you may move. Fixed sectionals look more finished; modular ones are easier to move and reconfigure.
Legs, arms and visual weight
Exposed legs reduce visual weight and make a room feel bigger, and they make it easier to clean underneath. Skirted sofas read more traditional. In a small room, pick a sofa with slim arms and raised legs so an 84 inch sofa looks lighter than its number suggests.
Fabric and durability
For a sofa used daily, look for a fabric rated for at least 25,000 double rubs. With kids or pets, go for 30,000 or more and a performance fabric. Textured weaves such as chenille hide wear well. Bouclé looks great but snags on cat claws.
Before you buy
- Tape the sofa outline on the floor and live with it for a day.
- Measure the doorways, hallways, stairs and elevator, not just the room.
- Mark where the front legs will land and make sure the rug plan works.
- Decide where the TV or focal point is and make sure the sofa faces it.
Frequently asked questions
- How long should a sofa be for my wall?
- No longer than two-thirds of the wall it sits on. For a 12 foot wall, that is a 96 inch sofa at most.
- What size sofa fits a small living room?
- In a room under 12 feet wide, stay with a 72 to 84 inch sofa and skip the sectional. A loveseat of 54 to 72 inches works for very tight spaces.
- How much space should be between a sofa and coffee table?
- Fourteen to 18 inches.
- What is the best sofa seat depth?
- Twenty-two to 24 inches suits most people. Go shallower if you are shorter and prefer upright seating, deeper if you are tall and like to lounge.
