Japanese Series
JIS B12
Belonging to the Japanese Industrial Standards (JIS), the JIS B12 paper size is a unique and intriguing aspect of international paper dimensions. This particular size, measuring 26 x 37 mm, is part of the B series under JIS, which is designed to cover a variety of uses ranging from books to posters.
What sets the JIS B series apart from others, such as ISO or ANSI, is its distinctive aspect ratio. Unlike ISO's 1:√2 or ANSI's 1:1.2941 ratios, JIS employs a unique 1:√2 ratio across all sizes in its B series. This ensures that two sheets of the next smaller size placed side by side are equal to one sheet of the larger size - an efficient and practical design feature.

Interesting facts about JIS B12
1: JIS B12 Paper Size
JIS B12 paper is a Japanese Industrial Standard paper size that measures 257 mm x 364 mm. It is slightly larger than the commonly used A4 size (210 mm x 297 mm) and smaller than the B4 size (257 mm x 364 mm).
2: Origin of JIS Paper Sizes
The JIS paper sizes were established by the Japanese Industrial Standards Committee in the early 20th century to standardize paper dimensions for various applications, including printing, stationery, and office supplies.
3: Metric-Based Sizing System
JIS paper sizes are based on a metric system, which means they use millimeters as their unit of measurement. This allows for precise and consistent dimensions across different paper sizes.
4: Relationship with ISO Paper Sizes
The JIS B series of paper sizes is closely related to the ISO (International Organization for Standardization) A and B series. While there are slight differences in dimensions, they share similar proportions and aspect ratios.
5: Common Uses of JIS B12 Paper
JIS B12 paper is commonly used in Japan for various purposes such as posters, flyers, brochures, and architectural drawings. Its larger size provides more space for content while still being manageable.
6: Compatibility with Printing Equipment
JIS B12 paper can be easily printed using standard printing equipment designed for A3 or tabloid-sized papers. However, it may require adjustments to accommodate its specific dimensions.
7: Limited International Adoption
Unlike ISO standard paper sizes, JIS paper sizes are primarily used in Japan and have limited international adoption. This can sometimes pose challenges when sourcing JIS B12 paper outside of Japan.
8: Paper Weight Considerations
When selecting JIS B12 paper, it is important to consider the weight or thickness of the paper. Different weights are suitable for different applications, such as lightweight papers for flyers and heavyweight papers for posters.
9: Environmental Impact
JIS B12 paper, like other types of paper, has an environmental impact due to its production process and disposal. Choosing recycled or sustainably sourced options can help reduce this impact.
10: Paper Size Evolution
The evolution of global paper sizes and series has been influenced by various factors such as historical usage, technological advancements in printing equipment, and the need for standardization across industries.
