The main principle of hanging painting decoration is that the center of the painting should be parallel or slightly lower than the line of sight of the standing person, and the parallel line of sight of the host can be hung at the center or slightly lower position of the painting (the center of the painting is above the ground 150CM) based on the center of the sofa; Should not be less than 2/3 of the main furniture. For example, the sofa is 2 meters long, and the overall length of the painting should be about 1.7 meters. At this time, four-foot (mounted 176× 1750px) calligraphy and painting is more suitable; For smaller kitchens and bathrooms, you can choose small landscape calligraphy and painting with a height of about 30CM. If you want to highlight the effect of calligraphy and painting, you'd better choose a large-format Chinese painting.
