It is necessary to keep in mind the factor of the size of the room, as well as the degree of illumination. For a light and spacious corridor, wallpaper is suitable, a drawing in which is large, one of the options may be the use of classic vertical stripes, as well as exotic colors. The use of such wallpapers in small corridors will be inappropriate, in addition, this can visually violate the structure of space. With the help of large colors, you can visually reduce the room, on the contrary, the presence of a vertical strip will unjustly lengthen it, creating the impression of a narrow well of a large height.
