The definition of sofa size internationally is width*deep*height, not long*width*height, and the unit is MM.

1. Width

Width refers to the biggest distance of the sofa from left to right, and the periphery of the two armrests, which is the "length" of the sofa in the usual sense, and the width of the seat refers to the width of the armrests on both sides.

It can be expressed as: seat width = width-handrail width*2

The single, two, and three of the sofa are determined by the width and seat width, because these two data determine the seat length of the sofa.

Two, depth

Deep refers to the maximum distance before and after the sofa, including the back of the back, is the "width" that everyone calls in general, and the depth of the seat refers to the depth of the back outside the back.

It can be expressed as: depth of the seat = depth-back dependent thickness

Due to the requirements of the style, the depth of the sofa is 800-1000, and the depth of 550-700 is normal, but some friends like deeper sofas because they will feel very relaxed when they are sitting. But the depth should not be too big.

① Consider the style;

② The depth is too large, and the human body will be difficult to rely on the back of the sofa;

③ If the edge of the sofa falls on the middle of the calf, it will affect the comfort.

Three, height

The height refers to the biggest distance from the top of the sofa from the ground to the highest point of the sofa, and the same concept as the common meaning "high", and the seat height refers to the distance from the ground to the surface of the seat.

The height of the European and American big sofas will be between 430-470. The reason for Asian figures is basically OK between 40-45? Essence

Due to the changing style and style of the general size sofa, it is difficult to have an absolute size standard, only some conventional general size.

The armrest of the sofa is generally 560-600mm high

Single style: length: 800-950mm, depth: 850-900mm; seat height: 350-420mm; back height: 700-900mm

Double style: length: 1260-1500mm; depth: 800-900mm trio: length: 1750-1960mm; depth: 800-900mm

Four-person style: length: 2320-2520mm; depth 800-900mm

It should be noted here: Generally, imported sofas or European sofas, classical sofas, and American sofas are relatively atmospheric and occupy a lot of space. If they are placed in the living room of small units, the living room will often look narrower.
