More Information
Defined by the GB/T 148-1997 Chinese paper size standard, Chinese paper sizes were introduced in China from 1912-1949. The paper has a single aspect ratio and folding a size in half produces the next sized sheet of paper and so on.
This paper size documents the ISO standard but does not follow the same principles.
