The living room is the face of a home, and the sofa is the face of the living room.
In a limited living room space, deciding on the size of the sofa to fit has always been a headache for everyone.
When searching for guides online, many of them are incomplete, and most are focused on introducing products. Today, Xiaowo will clarify everything for you with an article.
01
When choosing the length of a sofa, you should first measure the length of the background wall in the living room
The sofa should ideally occupy 1/4 of the entire space.
For a background wall ranging from 2.5m to 4m, it is recommended to choose a sofa of around 2m, suitable for 2-3 people;
For a background wall ranging from 4m to 5m, it is recommended to choose a sofa around 3.5m in length, with a three-seater section that includes an additional chaise longue, or a three-seater section paired with an extra lounge chair;
For a background wall over 6m, it is recommended to choose a sofa around 4.2m. If the living room is large enough, there are more options. Irregular sofas such as those with a curved or irregular shape can be chosen, depending on personal preference.
In addition, it is recommended to leave a space of 50-60cm on each side of the sofa for placing floor-standing side tables or green plants, which will provide decorative space for the living room and enhance its style and atmosphere.

How to choose the height and depth of a sofa?
The depth of a sofa is generally more appropriate to be between 60cm and 90cm.
The depth of a sofa is primarily determined by body height. For shorter individuals, a shallower depth is recommended, while taller individuals may prefer a deeper one.
Sitting on a deep and large sofa, if you lean back, your legs will be dangling in the air, which is exhausting for your legs; if your legs are not dangling, you cannot lean back enough, which is exhausting for your waist, and it will be very uncomfortable.
However, it also depends on personal preference. If you prefer the laid-back style of Ge You, it is recommended to choose a deep seat. But if there are elderly people living in the household, it is recommended to choose a smaller seat depth to facilitate the elderly getting up.
The sitting height is generally around 40cm, which is suitable for most body heights. It can also be adjusted according to personal preferences and usage;
The regular version of the sofa backrest is 48-60cm high, providing comfortable support for the shoulders, waist, and hips. If you want to be able to rest your head comfortably, a height of 80cm-90cm is required.
Many friends also prefer low-back sofas, which are more tailored to the design and overall style of the living room. In such cases, a leisure chair with a high backrest can be added to achieve a lounging effect.
