JB0

The JB0 paper size has dimensions of 1030mm x 1456mm (40.6 inches x 57.3 inches). With an area of approximately 1.5 square meters, it is the largest size in the Japanese JIS B paper size series. JB0 does not have any widely known alternative names, but its large dimensions make it suitable for uses that require substantial surface area like engineering and architectural drawings, wide format printing, and posters. As part of the JIS B series alongside the matching JIS A sizes, JB0 continues the tradition of Japanese paper formats tailored to industry needs while also aligning with international standards. Its origins can be traced back to Japan's adoption of the DIN standard in 1951 and subsequent local adjustments, eventually resulting in standardized JIS paper sizes including JB0 by the 1970s. Today, JB0 provides a large format option in the East Asian market while remaining relatively obscure on the global stage compared to the popularity of the ISO standard.
