Sofa Length: Though sofas can be anywhere between 70" and 96" long, standard three-person sofas tend to be between 70" and 87" long, and the most common length is 84".
Consider the two thirds rule
One approach to getting the right proportions is to aim for a sofa that's about two-thirds of the wall length. If you're using this tactic, bear in mind that generally sofas might be around 72, 84 or 96 inches (UK equivalents might be around 175, 210 and 240cm).
Three Seater: 84-inches wide by 40-inches deep, and a height of 33-inches. Standard Sofas: A range of 70-inches to 87-inches wide, with the most common width being approximately 84-inches.
In general, the width of a small sofa (A) is 72 inches or less, the width of a standard sofa (B) is 84-88 inches and the width of a grand sofa (C) is 96 inches or more. Once you've chosen a sofa style and size, you can get an even better idea of what the presence of the sofa will be like in your space.
Usually, a standard sofa will average about 86 inches in length and have three seat cushions.

I think for an adult human, we need about 24 inches of width. So 24, 24, 24. You wanna sit three people on your sofa comfortably, we're looking at about 72 inches of inner seating width.
In fact, choosing a larger couch (as long as it physically fits in the room) over a smaller option can actually make the room look bigger. That's because people's gaze goes to the couch, and with a big couch, they see plenty of inviting room for getting comfortable.
'When a couch dominates a space and leaves no room for pieces like a coffee table, side tables or accent chair, it is likely too big.
3 seaters can be the main element of a traditional suite, or they can be mixed and matched with other existing furniture in the living room. For larger families, keen entertainers or for those that simply have a more generous space to fill, a four-seater sofa can offer both the space and the comfort for four people.
Too many cushions and your living room could look cluttered, and they may even make the sofa less comfy. As a general rule, we reckon a two- or three-seater sofa needs a maximum of three cushions. If your sofa's larger then you can get away with more. Think six or more on a large corner sofa.
Seat Height
The average sofa height measures 17 to 18" from the floor to the top of the cushion. When thinking about this measurement, also consider how much you'll sink into the couch once you sit. Additionally, a great rule to keep in mind is that the deeper the seat depth, the lower the seat height needs to be.
This means your largest piece of furniture – for example, a sofa – should measure 2:3 of the area. Then work your way backwards from there. The coffee table should be 2:3 the size of the sofa, and so on. Once the bigger pieces of furniture are placed, it's easier to work smaller, decorative pieces around them.
Generally, most interior designers agree that a sofa should not touch the wall and that there should at least be a little gap to prevent the room from looking cramped, even if you only have a small living room.
Opt for a calming neutral shade
'A light-toned sofa in neutral colors, such as beige, cream, light gray, or white, can create a sense of openness in any room. These soft hues reflect the natural and artificial light that enters the room, making the space look brighter, airier, and more spacious.
Choose the style, shade and shape of your sofa wisely
Although deep tones are rich and luxurious looking, when it comes to large corner sofas it can be good to buy light colors that reflect the light, making the room feel bigger. Sofas with slim bases and higher legs let the light disperse from underneath.
The goal in choosing a sofa for a smaller room is for the sofa to be both visually appealing and functional. An apartment size sofa is usually a great choice. In general, you'll want to scale the size of the sofa to your room and be sure that you aren't overcrowding the space.
Generally speaking, you should place your TV around double the distance of the screen size away from your sofa. This sounds a bit confusing but it's quite simple. If you have a 60-inch TV, your sofa should be placed double the distance away - so 120 inches, or about 3 metres.
