Before collaborating with an interior designer and getting started with the planning process, each homeowner finds themselves asking: “How big should my living room be?”

If that’s what you’re also wondering, chances are that getting to know the average living room size and understanding the right dimensions should be on your priority list and the reason is simple:  a living room is where you spend most of your time and relax. That’s not to mention the fact that we use living rooms to entertain guests and create lasting memories.

But how can you ensure what’s the right size for your living room and whether the space is enough for both comfort and convenience?

In order to help you overcome this struggle, we’ve prepared a simple guide to avoid average living room dimensions.

Average Living Room Dimensions

The easiest way to resolve the issue of deciding the right size for your living room is to rely on a few factors, including the type of your house, the time you’re going to spend in your living room, activities, you’ll be performing there and of course, the standard size of the living room in a specific region you’re living in.

Normally, the average living room dimensions in US houses vary from 12 x 18 feet (216 square feet) to 20 x 25 feet (216 square feet). The sizes vary depending on pad or apartment size, but a living room may measure 10 by 12 feet (120 square feet), which is indeed a sufficient floor space for normal usage.

But since you’re probably more interested in the average living room size in a typical Las Vegas house, you should know that in Nevada, the sizes of houses are trending upward and Las Vegas is no exception.

In particular, Las Vegas homes follow this growing trend — the average living room dimensions have increased by 91% today since the 20th century. As a result, living rooms in most Las Vegas houses are larger than the national average.

Now, let’s take a look at specific dimensions of average living room sizes in small, medium, and large houses in Las Vegas:

Small Living Room Dimensions (in Meters & Feet)


Normally, small living room spaces start from 10 x 13 feet (3 x 4 meters) and go up to 12 x 18 feet (3.5 x 5.5 meters). While this square footage is enough to include some basic furniture, like a sofa, TV, a table, and a few decorations, you’ve still got a chance to make the most of your space if you have a small living room.

Here are some interior design tips to maximize your small living room:

  • Choose the items that have more than one purpose. For instance, you can include a sofa that doubles up as a bed or an ottoman that provides storage space. That way, you’ll be able to save space efficiently.

  • Another trick is to place your biggest piece of furniture against the walls. This is a great way to free up the walkway area.

  • In order to maximize the usage of the height of the room, you can also place your shelves or cupboards on the higher levels.

Practical Tip: Choose a foldable dining table for the occasions when you need an additional table for guests.

Medium Living Room Dimensions (in Meters & Feet)

A living room is considered medium if it starts from about 12 x 18 feet (3.5 x 5.5 meters) and goes up to around 15 x 20 feet (4.5 x 6 meters). If you’ve ever lived in a mid-sized room, you probably agree that these dimensions are enough for comfortable living and even hosting more than 5 guests.

 In Las Vegas, even luxury houses with modern designs include medium-sized living rooms, as this place allows the possibility to arrange your furniture in numerous ways.

Still, if you want to optimally use your medium-sized living room, you should be aware of the tips from our interior designer for the optimal furniture arrangement:

  • Aim to arrange your furniture either in a circular pattern or a U-shaped pattern. Both ways are practical to make the living room appear more inviting and cozy.

  • Combine furniture pieces of different sizes to avoid a plain, monotonous look and add some elements of lively design to your living room.

  • Homeowners try to keep the room especially tidy and versatile, often including built-in storage solutions and use them as focal points. This means that they build the design of the room based on the placement of this element and it’s more visible than other elements of the room.

  • Since lightning significantly determines the spacious look of any type of room, we suggest including layered lighting solutions in medium living rooms. For this, you can include a mix of ceiling lights, standing lamps, and table lamps.

Practical Tip: Lay a big rug in front of the sitting equipment to give the social place the feeling of togetherness.

Large Living Room Dimensions (in Meters & Feet)

As more and more newly established houses come with layouts that include larger living rooms than the average living room size, luxury homeowners often have living rooms that range between 20 x 25 feet (6 x 7.5 meters) or more.

If you’re fortunate enough to have such a large living room, you can easily create a grand, impressive environment, full of open spaces, multiple seating areas, and impressive decorative elements,

However, even in this case, it’s important to arrange the space thoughtfully and consider a few tiny details that, together, enhance the comfort of your large living room:

  • Divide the workspace into several zones with spots where people can sit down to enjoy a welcoming atmosphere.

  • If you prefer to include larger-sized furniture, it’s best to choose furniture that can be suitable for the scale of the room. For instance, large sofas and expansive coffee tables can help you prevent the furniture from looking lost in the space.

  • If there’s still much space after including large furniture, you can dedicate it to specific pieces, such as a grand piano, a large painting, or an impressive fireplace. The best part here is that each of these pieces can serve as a focal point of your large living room.

Practical Tip: Avoid small rugs in large living rooms. Instead, aim for a large, even oversized rug that can tie the parts of your area together and make it look more cohesive.

Bottom Line

Now you already have some guidance on the average living room sizes so that you can carefully plan your design, whether you have a small, medium, or large house. However, regardless of the dimensions of your living room, if you want to make the most of your space, try to carefully consider factors such as lighting sources, furniture arrangement, and colors.

Nevertheless, if you have trouble finding the perfect balance by yourself and creating a harmonious living room design, don’t hesitate to contact our professional interior designer at Sean Design and let him guide you plan your perfect home design.
