A reasonable sofa size can make the sofa unique in shape and comfortable to sit on. So how to design a comfortable sofa must fully consider ergonomics. The armrest height, seat height, seat depth, left width and other dimensions of the sofa must be based on human body dimensions. For example, the maximum range of motion of the arm when standing, the calf height and thigh length when sitting, and the range of motion of the upper body are all closely related to the sofa size.

According to the number of people sitting on the sofa, it can be divided into single sofa, double sofa and triple sofa.

Single sofa size

The size of a single sofa is generally 760mmX760mm, and 810mmX810mm is sufficient at most. Many people like imported sofas, but it should be noted that the size of this type of sofa is generally 900mmX900mm. Putting them in the living room of a small unit will often make the living room look small.

Loveseat Size

The size of a standard double sofa is something that many friends want to know. Below, I will briefly introduce the size of a standard double sofa and talk to you about how to determine the size of a double sofa? How to ensure that the double sofa is suitable after you buy it. Knowing the size of a double sofa will help you avoid making mistakes when buying a sofa, and you will have a good idea of ​​what you buy. When you put it in your home, it will not be too big to fit, or too small to leave the living room empty. Therefore, it is necessary to understand the size of a standard double sofa, which is also very meaningful for home life.

The size of a standard double sofa is generally between 1400mm and 2000mm in width and about 700mm in depth. Of course, these numbers are not fixed, but a fluctuation range. Within this range or similar sizes, the size of a standard double sofa is more reasonable. In addition, the seat cushion should be sunken about 80mm after a person sits on the sofa. If the numbers of all aspects of a double sofa are almost the same, then its sofa size is the standard double sofa size.

Three-seat sofa size

The size of a three-seat sofa suitable for a public living room is generally between 2.2 meters and 2.3 meters. (It is best to separate the seat and back cushions of a three-seat sofa into two for sitting and two for backing. Separating them into three will appear small.) The length of a three-seat sofa is generally 1750-1980mm.

Corner sofa size

Many people like corner sofas. The corner should be a corner table with a size of 760mm x 760mm. If the corner is made into a sofa, the person sitting will occupy the adjacent position and will not be comfortable because his feet are placed at a right angle. To make the corner seat comfortable, the size of the corner sofa should be 1020mm x 1020mm. The highest position of the seat should be 400mm, and then tilted downward at a 6° inclination. The seat depth is about 530mm (according to the principle of ergonomics, it cannot be too deep, otherwise you will not be able to sit to the bottom. The foreign sofas of 1000mm x 1070mm are just larger armrests and backs, and the seat depth is increased by 24in). 

Sofa armrest size

The armrests of a sofa are generally 560-600mm high. Therefore, if the sofa has no armrests and uses a corner table or a side table, the height of the corner table or side table should also be 60mm high. This is convenient for making phone calls, writing, placing table lamps, etc. The sofa should be moderately soft and hard. A sofa that is too hard or too soft will cause back pain. So, how do you judge the hardness of a sofa? If you sit down and your body is jerked and you feel like you are sitting on a hard board, this sofa is too hard. If you sit down and your body sinks too deeply, you feel like you are sitting on an empty space, and you even feel the bottom frame of the sofa, this sofa is too soft.

Coffee table size

The size of a coffee table is usually 1070mmx600mm, and the height is 400mm, which is the height of the sofa seat. In this way, the place looks more spacious. For medium and large units, coffee tables of 1200mm XI 200mm are sometimes used, and at this time, the height will be reduced to 250-300mm. The distance between the coffee table and the sofa should be about 350mm.
