Unlike its ANSI counterparts, which are primarily used in North America, the JIS B2 has a significant presence in Japan and other parts of Asia. Its dimensions make it ideal for larger print materials such as posters, diagrams, and architectural drawings.

The JIS B2's unique size also lends itself well to folding into smaller formats while maintaining its aspect ratio. This makes it a popular choice for brochures and other marketing materials that require a larger initial layout but need to be compact for distribution.

The versatility and thoughtful design of the JIS B2 paper size make it an excellent choice for various professional applications across different industries.
