The size of a sofa seems to be common sense, but in fact many people are confused. When buying a sofa, many people often only pay attention to whether the color matches and whether it is comfortable to sit on, and then buy it home directly. As a result, they find out that they are wrong after buying it, and waste money. Therefore, when buying a sofa, the size is very important, and the size is also related to the number of family members and the size of the house. So, how to choose the right sofa size? The following provides you with specific tips and suggestions.

1. Sofa length

The length of the sofa is usually chosen according to the length of the wall in the living room. Generally speaking, the length of the sofa should be between 1/2 and 2/3 of the length of the living room, which can ensure that the sofa does not appear too crowded and ensure the overall balance of the living room.

2. Sofa width

The width of the sofa directly affects the sitting comfort. Generally, the width of a single sofa should be between 80-95 cm; the width of a double sofa is 126-150 cm; and the width of a three-seater sofa is 175-196 cm. Of course, these are just general recommendations, and specific adjustments need to be made based on the body shape and habits of family members.

3. Sofa height

The height of the sofa should generally be kept between 35-42 cm, to ensure that people's knees are not too high or too low when sitting down. In addition, the height of the sofa backrest should also be between 55-70 cm to provide adequate support.

4. Seat depth and armrest height

The seat depth refers to the distance from the front edge of the sofa to the backrest, which affects the sitting comfort. Generally speaking, the seat depth is between 48-60 cm. The height of the armrest should be kept between 62-65 cm to provide appropriate support for the arms.

5. Consider access space

When choosing a sofa, you also need to consider the distance between the sofa and other furniture in the living room, as well as the width of the door. Make sure the sofa can be smoothly delivered to the home and maintain an appropriate distance from other furniture to facilitate daily activities.

Finally, it is recommended that you use paper or other items to simulate the size of the sofa before purchasing it, and put it on the ground for comparison. This will allow you to more intuitively feel the proportion and comfort of the sofa in the actual space, helping you make a more appropriate choice.
