General Considerations in Choosing the Right Couch Dimensions

Most people buy a couch without first considering its dimensions. Thus, they end up with ones that are either too small or too big for their living room or other spaces.

The lengths and depths of couches widely vary. A standard couch or sofa often measures 6 to 8 feet in length with a depth range of 32 to 40 inches. But for couches that are 4 to 6 feet long, their depths usually measure 28 to 30 inches. You should also consider that the depth of the back and arms of the couch will reduce its actual seating depth.

It’s important to consider some factors if you want to get the right couch size for your living room or other room in your home. Before buying a couch, consider the following things below:

Sofa couch dimensions – how to choose which is best for you?

1. How Do You Intend to Use It?

First, you need to know the purpose of the couch you’re buying. How do you intend to use the couch? You might say that you will use it as your favorite reading spot or a place where you will be entertaining your guests.

But be honest with yourself. If you’re an average person, most of the time, you will be watching your favorite flicks on your couch. So, if you think of binge-watching movies with your buddies, then go for the longest and largest couch you can find.

2. How Do People Move in Your Space?

What is the traffic flow in the space where you intend to put the couch or sofa? Most couches with typical couch dimensions or average couch dimensions will not affect the traffic flow if the room space is relatively large. It’d be nice if there’s a free flow of traffic in the area where the couch or sofa is placed.

The standard sofa size or average couch size shouldn’t also impede the flow of traffic in your living space. If it produces traffic obstruction, you would be better off with a couch that is smaller than standard sofa size or sofa couch dimensions.

A good example of a couch that can be used in any space is the Divano Roma Classic 2 Piece Colorful Velvet Convertible Living Room Sofa. This convertible couch features 2 separate pieces that you can put together or set apart to fit any available space.

The couch has a low profile frame that stands on dark wooden legs. It is upholstered with soft velvet fabric and is available in different colors to suit your room’s color scheme. The couch dimensions are 87 inches wide, 30 inches deep, and 33 inches high.

3. What Is the Shape of the Space?

Consider the shape of the room where you will put the couch. Some rooms have load-bearing pillars and other kinds of obstruction, while other areas are more spacious and freer.

The right couch or sofa for your particular space should not go beyond any existing wall. Conversely, it should not be floating aimlessly in a very large space. Also, the couch should not block the view of the special architectural features of the room, such as built-in shelves, fireplaces, or windows. All the existing conditions in the room must be considered before choosing a couch.

4. Is It the Right Scale?

Couch or sofa dimensions should be in the right proportion with the size of the room. A small room does not need a big couch and vice versa. Always remember that the length of the couch should not occupy the entire wall length. Make sure that you provide at least 18 inches of space on both sides of the couch.

5. Will the Couch Be Able to Pass Through Your Doorway?

Most homeowners forget to think about this simple consideration when buying a couch. When the couch is delivered, they have a hard time squeezing the couch through the door. Some may run into the issue of having to break down their couch just to get it inside their house.

Choosing the Right Couch Size According to the Number of People

Another method of choosing the right couch size is by considering the number of people that will sit on it most of the time. You also need to consider whether these people are kids or adults.

The below list will help you choose the right couch or sofa dimensions according to the number of people that you want to accommodate. The seating width of a couch or sofa is used as the primary determining factor in the list below.

  • Couch for 2 People – The minimum seating width should be 50 inches. The width of the arms is not included here.
  • Couch for 3 People  The minimum seating width should be 78 inches; arms not included.
  • Couch for 4 People  The minimum seating width should be 90 inches; arms not included.
  • Couch for 5 People – The minimum seating width should be 108 inches; arms not included.

It is perfect for small apartments with its typical couch dimensions of 78. 5 inches (length) by 35 inches (height) by 30.3 inches (width).

Choosing the Right Couch Size According to Available Space

In choosing the right couch or sofa dimensions, there is an interplay between personal aesthetics and available space. For a big room, it is a no-brainer to select a big sofa or couch. Conversely, a smaller room needs a smaller couch. However, if there is no other seating in the room, you can use a bigger sofa or couch that is not unreasonably large for the size of the room.

To get the available space in the room, you need to arrange existing furniture to make way for your new couch. Allocate and measure the area where you’d want to put the couch. Allow a minimum space of 30 inches in front of the couch. This space will serve as your walking space.

If you want to have a coffee table, add around 12 to 18 inches of space between the couch and the coffee table.

You should also consider how the couch will affect the visuals of the room. Will the addition of the new couch enhance the visual appeal of the room? That should be your foremost objective. If you have a large room with a high ceiling, you must ensure that there will be no large space gaps between the furniture and fixtures inside the room.

If your room is rather small with a standard 8-foot ceiling, your aesthetic objective is not to fill it with too much furniture and fixtures. It will only confound the visual appreciation of those who will enter the room. In this case, abstinence is wiser than incontinence.
