Choosing the right sofa for your room can make the difference between an airy, open space, and a room that feels over-crowded.
With so many couch types available, it’s important to get one that fits your space, but can also have you relaxed comfortably regardless of your activity.
Below, you can find all the sofa measurements explained in relation to your purpose for getting one, as well as your room size and other pieces of furniture you own.
Read along to find helpful tips so your living room feels friendly and welcoming instead of overstuffed.
Sofa Dimensions vs Room Size
The rule of thumb is that your sofa’s dimension has to fit your room size, so:
- Get a full-size big sofa if you have a big room.
- Get a small sleeper sofa if you have a small room.
The caveat is that, even if your room is small, you can get a medium-large sofa if you have no other seats in that room.
Other factors to consider are:
Space and Measurements
Measure the space you have for your couch, but ensure that all your other furniture is in place first. Account for at least 30 inches in front of it where you can walk.
If you want a coffee table, add its width to the mix, then another 15 inches wide on average for the space between the sofa and the coffee tables.
Pro tip: Consider getting your standard couch dimensions in mm particularly if your living room is extremely small and you need to account for every last bit of space available.
Standard Sofa Sizes
Sofas come in different shapes and sizes:
- Standard sofas: 6-8 feet length and 32-40 inches deep
- Loveseats: 4-6 feet length and 28-30 inches deep
Sectional sofas dimensions are bigger than these standard measurements above.
Pro tip: the sitting space is smaller because the armrests and back rest support cut into these measurements.
Design and Proportions
Choosing the right size of furniture depends on the sofa size and vice-versa.
- Consider a long, accommodating couch with a low-back interior design if your room’s ceiling is small in size, but your room is wide.
- Consider a loveseat with a tall seatback if your room is small, but has a high ceiling.
- Ensure your sofa is the same size as your other furniture. If you have small chairs, consider a one or two-seater. If your room is huge, consider a sectional or a wide davenport.
Your room has a personality created by furniture, light, colors, and coat. Before buying a sofa, consider that:
- A skirted couch is better for a large room with few furniture objects.
- A couch with exposed legs works better in a small space because it makes it look bigger.
- Get a couch with narrower armrests if your room is small, but you have three+ people in your house.
- Choose a neutral-color sofa if you have a small room because neutral colors light up your environment.
SUMMARY: Your room size influences the size of the sofa you’ll get because you don’t want a sofa that’s too small to sit on or one that’s too big to move around. However, the sofa size also influences the perceived size if you choose the right model.
What is the Standard Size of a 2 Seater Sofa?
A two-seater sofa offers about 50-67 inches for actual sitting, but its dimensions will vary depending on style, type, armrests size, and so forth. Here are the average 2 seater standard sofa dimensions in feet:
- 2.5-foot cushion width
- 5-foot total width without armrests
- 0.33-feet backrest thickness
- 1.5-foot cushion height
- 1.5-foot seat height
- 3-foot total height
- 2.7-foot total depth
- 2.33-foot seat depth
- 4.5-foot overall length
- 0.66 x 0.16 x 0.33 armrests dimensions
SUMMARY: A standard two-seater sofa is 5 (W) x 3(H) x 2.7 (D) feet.
What Are the Dimensions of a Standard Loveseat?
Loveseat’s dimensions vary depending on preferences and living room sizes. Their width is usually between 48 to 72 inches, armrests included. Their arm height and width are around 36 inches in total.
Loveseats’ lengths vary depending on their design style, shape, and cushion sizes. Here are the average size in inches:
- Small standard: 52 inches
- Medium: 58 inches
- Full: 64 inches
- Loveseat sofas: 71 inches
- Twin-sized: 48 inches
Loveseats are usually 20 inches high, but twin-sized loveseats can get up to 28-inch high. Conversely, the recliner dimensions are bigger, so a twin-sized loveseat is better for a reading corner.
Loveseats’ widths are more difficult to predict because they depend on a lot of factors, including style and how stuffed your seat cushions are.
SUMMARY: Loveseats vary in dimensions, depending on how big your loveseat is. The standard loveseat size is 48-72 (W) x 36 (H) x 36 (D) inches.
What is the Average Height of a Sofa?
Although sofas have different seat heights, the typical average couch size range is 15 to 20 inches high off the floor plan. The average height for your sectional sofa is around 1.5 feet off the floor. Make sure your sofa’s height can accommodate the people who will sit on it the most.
An average backrest is about 30 to 36-inch high. Choose a low-profile sofa if you have a small room with a modern décor because they have a streamlined design. If your room has a tall ceiling, get a sofa with a taller backrest.
You can raise your sofa’s height by using stacked studs and plywood strips under your couch’s legs.
SUMMARY: The standard sofa height is 17.5 inches, with another 12-19 inches for the backrest.
Two Cushion Sofa vs Three Cushion Sofa
The main difference between a two or three-cushion sofa is how many people will sit on it.
It’s obvious that 3 seater sofas are best for three people, but two-cushion sofas can also accommodate up to four people. The problem is that at least one of them will have to sit uncomfortably in between the two pillows.
Before choosing one or the other, take these factors into account:
How will you use the sofa the most? Some people like a cushiony sofa that’s perfect for reading. Others need a sofa to binge-watch Netflix or play video games. Some people like to nap on their sofas or cuddle with their significant others. Or you might want this sofa to host movie nights with your friends.
Here’s what you should choose:
- A large two-cushion couch if you have frequent visitors. Most large two-seaters can accommodate three+ people, so this sort of couch maximizes the seating area. Besides, people don’t usually sit down at parties, and even if they do, they mostly just take a quick breather before getting up again to socialize.
- A small two-cushion sofa for reading, watching TV, and playing video games. You don’t need a lot of space for these activities unless you want to lie down. An L-shaped sofa works well for a reading corner in a smaller room.
- A long, wide sofa if you’re lying down for a nap. This issue is more difficult because both the two and the three-cushion sofas have disadvantages. Remember that napping on your sofa is not as comfortable as sleeping in your bed. The two-cushion sofa has your bum sitting uncomfortably right between the cushions. The three cushion sofa is larger, but the middle cushion tends to get flat faster, which has your core sitting lower than the rest of your body.
The Number of People
It’s important to choose a sofa that accommodates the total number of people in your home office. If you have a house full of people, small children, and pets, it’s best to choose a three-cushion sofa.
However, consider that the Burrow couch dimensions are 86 (W) x 36 (D) x 35 (H) inches, even though it’s a two-cushion sofa, enough for a family of three.
Even if a two-cushion sofa can accommodate up to four people, these people won’t have a very cozy sitting experience if they’re living in that house.
It’s different for your friends that come to your occasional parties than the people who are always there.
Three-cushion sofas are better for large families because they’re easier to clean. If they spot, you can easily take out one pillow, and your family can squeeze in on the remaining two.
Don’t buy your couch without checking its measurements first. Check the furniture dimensions in order to ensure everything fits.
Choose a smaller sofa if you have a petite living room. A medium two-cushion sofa is good for a two-person household, while a large three-cushion sofa is best for a bigger household.
A two-cushion sofa works well with standard dimensions. If you have bigger chairs in your dining room, consider a three-seater size sofa.
SUMMARY: Choose a two or three-seater sofa depending on your purpose, activity, number of people, living rooms size, and other furniture pieces.
How Do You Pick the Right Size Furniture?
If you just stumble into a place, look at the furniture and buy whatever looks suitable, you’ll find yourself having a grand time but you are going to face issues and challenges when you are moving from one place to another. A lot of time people end up buying oversized furniture which ends up getting broken soon after moving. On the other hand, if you are looking for something that fits the right space, it is a lot easier to look for and buy.
The different sizes of your room need to be determined by looking at the walls and other spaces in your house. Ideally, you would want to fill the wall that you will be moving out of with furniture and that also has the right size on it. If you are just about to move into a house, you may want to build a wall using cardboard and paint it in a color that matches the color of the living room. Steps on How to Choose the Right Furniture. The best way to figure out the right furniture is by first looking at the size of your walls and the size of your living room. Depending on the way your home is laid out, you may want to consider the types of furniture you need to buy and how you can fit them.
What is the LxWxH?
The LxWxH displays the human body in relation to objects – like we use the EYE to see the world. The two numbers (or 0-100) also help with basic measurements and more complex math. Example – To tell you how tall someone is, you use the LxWxH. When we calculate someone’s length, we multiply the legs, arms, and body (usually measured from the feet to the hips) times the height in inches. So when you take someone’s height in feet and multiply it by the LxWxH, you get their height in inches.
LxW stands for leg, W for the upper body, H for the lower body. Why do some people get a different number? No one has a different number on their driver’s license then you have. The thing that happens is that you are born with a different number stored in your body, and that number is different from what your license shows. In the case of Lic. #12 & 1, I am 3 inches shorter than you, and my license says I’m 5’3.6”.
Is Length the Same as Depth?
As with many things in nature, there are some pretty technical ways in which the world is “never really more than two dimensional.” Take the basic mechanical operation of extending a screw into a hole or socket. “The world we live in is a three-dimensional mechanical system, but in fact, the world is actually only two-dimensional, with a surface and depth. There are also ways in which the world is multi-dimensional. A great example of this is a photograph. Some cameras can actually photograph objects that are four-dimensional or even five-dimensional. A bird’s eye view of a four-dimensional world could be helpful when designing an art installation. With more advanced technology like this, it becomes possible to create new materials and build new objects that are truly multi-dimensional.
Use a sofa size calculator to get your sofa dimensions in cm. The calculator will help you convert to a metric system and decide on the best sofa size according to the other objects in your room.
Remember to keep balanced proportions between your sofa’s dimensions, the other objects in your room, and your room size.
The main factor to take into account before purchasing a sofa is your purpose, though. A sofa for entertaining guests in a small room will look very different than a sofa for watching TV in a big room.
