Abstract: In recent years, with the development of modernization and the increasing aesthetic ability of consumers, more and more people have begun to pay attention to the decoration and contextualization of interior design. The requirements of interior decoration have become more and more refined and systematic. More designershave started to explore the one-stop soft decoration design platform, which makes the materials and graphic semantics of soft decoration more unified and coordinated, and gives the design more emotional expression, so as to narrow the distance with consumers and meet humanistic care. The systematic design of space graphics is the most effective and widely uesd design strategy in interior soft decoration design. The research also provides new ideas and thoughts for interior soft decoration design.
