Japanese B Series

The Japanese Industrial Standard (JIS) defines two series of paper sizes: the JIS A-series and the JIS B-series. The JIS A-series is identical to the ISO216 standard A-series, only with slightly different tolerances. However, the JIS B-series is completely different to the ISO216 standard B-series. The area of Japanese B-series paper is 1.5 times that of the corresponding A-series paper, so the length ratio is approximately 1.22 times the length of the corresponding A-series paper. The aspect ratio remains the same for JIS B-series paper as it is for A-series paper. Both JIS A and B-series paper is widely used throughout Japan and Taiwan.
