JIS B1
Belonging to the JIS (Japanese Industrial Standards) series, the JIS B1 paper size is a unique and versatile format. It measures 728 x 1030 millimeters or 28.66 x 40.55 inches, providing ample space for various applications.
Interestingly, the JIS B1 is part of an aspect ratio that's rooted in the square root of two (√2), a characteristic it shares with ISO paper sizes such as A4 and B5. This mathematical relationship ensures that when you cut or fold a sheet in half along its longest side, you get two smaller sheets with the same aspect ratio as the original.

The JIS B1 size is not directly equivalent to any ANSI (American National Standards Institute) standard sizes. However, it closely matches ANSI D (22 x 34 inches), albeit slightly larger. This similarity allows for some interchangeability between these formats in certain contexts.
One fascinating fact about JIS B1 is its widespread use in Japan for posters and other large-scale print materials due to its generous dimensions. Its popularity extends beyond Japan's borders too; many international businesses adopt this format when targeting Japanese markets to align with local preferences.
Whether you're designing a poster or preparing an architectural blueprint, understanding the specifications of JIS B1 can help optimize your layout for this specific format and potentially increase your reach within Japanese markets.

Interesting facts about JIS B1
1: JIS B1 Paper Size
JIS B1 paper is a standard paper size used in Japan, measuring approximately 728 x 1030 millimeters. It is part of the Japanese Industrial Standards (JIS) series, which includes various paper sizes commonly used in Japan.
2: Origin of JIS Paper Sizes
The JIS paper sizes were established by the Japanese government in the early 20th century to standardize paper dimensions for industrial and commercial purposes. The goal was to improve efficiency and reduce waste in printing and document handling.
3: Relationship with ISO Paper Sizes
The JIS B series of paper sizes is closely related to the ISO (International Organization for Standardization) A series. While there are slight differences in dimensions, both systems share a similar aspect ratio of approximately 1:√2, allowing easy scaling between sizes.
4: Unique Aspect Ratio
JIS B1 paper has an aspect ratio of approximately 1:√2, meaning that if you divide its longer side by its shorter side, you will get a value close to the square root of two (√2 ≈ 1.414). This aspect ratio allows for easy scaling when creating larger or smaller prints.
5: Common Uses
JIS B1 paper is commonly used for posters, large-scale advertisements, architectural drawings, and other visual displays that require a significant amount of space. Its generous size provides ample room for detailed designs and information.
6: Variations within JIS Series
The JIS series includes various other sizes such as JIS A (for general printing), JIS B (for posters and large prints), and JIS C (for envelopes). Each size within the series has its own specific dimensions, allowing for versatility in different printing applications.
7: Historical Influence
The JIS paper sizes were influenced by the traditional Japanese paper sizes, which have a long history dating back to ancient times. The adoption of standardized sizes helped bridge the gap between traditional Japanese paper dimensions and modern printing practices.
8: Compatibility with Printing Equipment
JIS B1 paper is compatible with various printing equipment commonly used in Japan, including offset presses and large-format printers. Its standardized dimensions ensure smooth operation and compatibility across different machines.
9: Availability of JIS B1 Paper
JIS B1 paper is readily available in Japan through stationery stores, print shops, and online suppliers. It comes in various weights and finishes to cater to different printing requirements.
10: International Adaptation
Although primarily used in Japan, JIS B1 paper has gained some international recognition due to its compatibility with ISO A series sizes. This allows for easier collaboration between Japanese and international designers or printers working on projects that require scaling between different standards.
