Sofa sizes and dimensions

The standard dimensions of living room furniture is quite different to the typical dimensions of the average sofa that has been made to be used as bedroom furniture. This is partly due to the average dimensions of the floor plan and living space of the typical home. And also partly due to the ingenious designs of the different types of sofas.

Luckily for us, the traditional sofa has some basic standard measurements. You can choose from a common option of a variety of sizes of furniture pieces. If you so desire, you can as well have your own sofa built to detailed specs. Shorter people might need a “shorter sofa”, but if you are of average height, then the average size of couches is good enough.

How To Measure A Sofa

1. Always start with width. Measure the distance from arm to arm because that is usually the widest part of the sofa. You need to make sure that you take the measurements at the widest point. Eg: if the couch you selected has curved arms (rolled edges), measure from the outside of the widest part of one arm to the other arm. For armless sofas just measure from the outer tip of one edge to the outer tip of another edge.

2. Measure the height—measure from the floor to the tip of the back at the highest point. Eg: a camel-back arched sofa will be highest in the center, measure from there to the floor. 

3. Measure the depth—measure from the outside edge of the seat all the way to the back. It is best to do it from by standing at one of the sides.

4. Measure the diagonal depth—measure a straight line from the top back of the frame to the bottom front. This is also best done by standing at the side of the sofa and measuring a diagonal line of the entire sideview of the sofa.

The Best Sofa For You

When picking out your sofa, you can try and remember the 5S.

Size is one of the most important considerations to make when choosing the right sofa. If the sofa doesn’t fit your living room, we have a problem.

Style is another important consideration to make when sofa shopping, as style is often a reflection of your personality. consider what style you have and how that may be interpreted into your sofa choice.

Shade of your sofa is another important decision to make, as the colour of the sofa can evoke certain moods and feelings depending on the colour scheme. Ask yourself: how do you want the space to make you feel? What do you want people to think of you when they enter the space?

Softness and firmness is another important factor to consider for the right sofa. This depends on the purpose of the sofa. If you are using it for guests and only guests, a firm sofa is better. On the other hand, a softer sofa is ideal for everyday family use. When you sit on a softer sofa and sink in, it creates more of an informal and casual vibe.

Sense and practicality is the last essential to consider for the sofa. If you have any family pets, a leather sofa is ill-advised as their claws may accidentally rip through the material. On the other hand, if you opt for a sofa that uses fabric, ensure you have a spot cleaner on hand for any unexpected stains that shouldn’t be vigorously wiped off with a cloth.


Once you understand sizes, you only have to worry about the upholstery choices and stock items of your favorite furniture outlet. Quick tip, pick durable upholstery and some gel memory foam for the cushions. Chair sleepers will appreciate the gel memory foam. There is a wide variety of fabrics out there and it is not compulsory that you have leather sofas .

Simply buy the best that you can comfortably afford. Before you go shopping, please leave a comment behind and let your friends know about the right chair size by sharing the article.
