It's an age-old design dilemma when it comes to buying a couch for your living room: sofa vs. sectional. Should you stick to a standard three-seater or go the roomier sectional route?

The truth is, there is no magic answer to that question. The best sofa for your living room and lifestyle could be different than the best sofa for someone else. Deciding which is the right choice for you comes down to a few basic questions: What's your budget? What's your lifestyle? Is your home the go-to for parties and movie nights? The list goes on.

Below, I've laid out the differences between sectionals and sofas in all the ways that matter, including size, price, and perhaps most importantly, expert opinion. Indeed, a few interior designers will weigh in, offering their tried-and-tested tips for deciding between these two popular seating options. And to help you further down your decision-making journey, I even added a few shopping options along the way.

The difference between a sectional and a sofa

A sofa is defined by its straight (or sometimes curved) shape and linear cushion arrangement. The three main offerings are loveseats (two people), three-seaters (three people), or a single-cushion design that can seat two to three people, depending on the sofa's length. "A sofa is a longer upholstered seat made as a single frame with a back and arms on the sides.," explains Andrea Lackie of Andrea Lackie Design.

A sectional, on the other hand, is configured differently than a sofa (and it's usually larger). It typically "has a chaise return in addition to the singular back, or even multiple returns depending on the configuration," adds Courtney Sempliner, owner of Courtney Sempliner Designs. The most common configurations are chaise sectionals, U-shaped sectionals, or L-shaped sectionals.

  • Chaise sectionals: a two or three-person sofa with an attached chaise on either the left or right side
  • U-shaped sectionals: a two or three-person sofa with longer arms or chaises on either side; its shape forms the letter "U"
  • L-shaped sectionals: a two-person sofa is joined with a three-person sofa at a right angle thanks to a connecting corner cushion; its shape forms the letter "L"

How do I know which to buy: a sofa or a sectional?

Personal preference aside, a sofa might be the right choice for you depending on the following:

Price: Because they are smaller, sofas are typically less expensive than sectionals. If you're working with a smaller budget, a sofa-accent chair vignette might make the most sense.

Lifestyle: Do you have a large family? Do you gravitate to the couch for lounge sessions and hang-out time? If the answer is "no," you might not need something as large as a sectional. Just one loveseat or three-seater might do the trick. (Or, you could try a combination of the two to build the same seating capacity as a sectional.) "It is best to use a sofa when you have limited space or want a more formal setting," Andrea says. "Additionally, a sofa is a good choice when you want a more fluid furniture plan where the sofa could be paired with chairs or poufs." A sectional, however, is best for "more casual, informal spaces." where you're looking to curl up, get comfy, and relax. Courtney adds.

Aesthetics: Generally speaking, there is less variation or room for customization in the sectional market. You probably won't find one upholstered in a funky material or accented with unique hardware. This is going to take up a lot of your living room real estate, so you might not want something so flashy, after all — but if you do, a combination of sofas might be more your speed.

Longevity: As online interior design service Homzie points out on its blog, sectionals don't "grow well with you." If you move, it's unlikely your sectional is something you're going to take along with you, since they tend to be configured to the size of the room you purchased it for. Homzie's experts recommend skipping a sectional if you plan to move in the next 5 to 7 years.

Traffic Flow and Space: "A sectional works great in a corner as it fills the room and can avoid any dead-end corner space," adds Silvia Roldan, lead designer at the Stylesmiths. "Sectionals can also help close off a low-traffic area of a room." That said, they can block traffic, too. Make sure your sectional won't close off the room so much that it becomes cumbersome to move through the space.

Intended Use: Another great tip from Homzies — if you like to eat and drink on your couch, ensure you can easily access your coffee table from the sectional you're considering. If the answer there is no, you might prefer loveseats/three-seaters flanked by side or drink tables instead.

Room: If you're furnishing a rec room or basement — a multifunctional space with various sections to lounge and entertain — a sectional is great. For your front room, though — an area meant more for conversation than relaxing? Sofas. "Whereas a two or three-seater sofa is designed more for a small living space or more formal sitting room, corner sectionals are ideal for TV rooms, dens, basements, etc. — wherever you see yourself watching movies and TV, lounging, relaxing, potentially napping, etc," says Heather Goerzen, lead interior design at Havenly. "Due to the extra seating space, they’re great for larger families or people who love to host."

Is it a good idea to have a sofa and a sectional together in a room?

"Both styles of sofa can be used in a room together. However, it comes down to how big your room is and the location of the sofas," says Silvia. "If I've specified either a sectional or a sofa, I will combine this with a couple of armchairs to provide flexible seating options, or team two sofas together."

A large living room allows for both these seaters to exist together and even increases the functionality of the room. In a luxury living room, you could create two seating systems – a formal one with sofas, armchairs, and ottomans, and an informal one with a sectional and stools.

"Do keep in mind that when planning a layout, it's important to have adequate seating and different types of seating," says Victoria Holly, principal, and founder of Victoria Holly Interiors.

"I like to have at least three types of seating, such as a sectional or sofa, accent chairs, and then an ottoman. This is great for kids who want to play while watching TV. Having multiple types of seating also allows for breakout conversations as well as main conversations within the space."
