B Series



Belonging to the ISO 216 standard, B13 is a unique paper size that holds its own significance. This standard, recognized internationally, ensures consistency across different countries and industries. The B13 paper size is part of the B-series, which was designed to provide sizes not covered by the A-series.

The dimensions of a B13 paper are 44 x 62 mm or 1.73 x 2.44 inches. This compact size makes it ideal for specific applications where larger sizes would be impractical or unnecessary. It's worth noting that each successive size in the B-series is half the size of the previous one when folded parallel to the shorter sides.

Interesting facts about B13

1. The Origin of B13 Paper

B13 paper is part of the ISO 216 standard, which was first introduced in Germany in 1922. It is a standardized system for paper sizes that is now used globally.

2. Unique Dimensions

B13 paper measures 250 mm x 354 mm (9.84 inches x 13.94 inches). Its dimensions make it slightly larger than the commonly known A4 size.

3. Limited Usage

B13 paper is not as widely used as some other ISO paper sizes, such as A4 or Letter size (8.5 inches x 11 inches). Its limited usage can make it harder to find commercially.

4. Niche Applications

The B13 size finds its applications in specific industries like printing and graphic design, where its unique dimensions may be required for certain projects or layouts.

5. Compatibility with Other Sizes

The B series of paper sizes, including B13, follows a consistent aspect ratio of √2:1 (approximately 1:1.414). This allows easy scaling between different sizes within the series without altering proportions.

6. Enlarging and Reducing Documents

If you have a document printed on B13 paper but need it on a smaller size like A3 or A5, you can easily reduce it by halving the longer side each time while maintaining the aspect ratio.

7. Historical Significance

The adoption of standardized paper sizes like B13 helped streamline printing processes and improve efficiency during the early days of mass production and distribution of printed materials.

8. International Acceptance

ISO 216, which includes B13 paper, is recognized and used by most countries worldwide. This standardization facilitates international communication and document exchange.

9. Paper Weight Considerations

B13 paper can come in various weights, denoted in grams per square meter (gsm). The weight affects the thickness and durability of the paper, making it suitable for different purposes.

10. Customization Options

If you require B13 paper for a specific project or purpose, many professional printing services offer customization options regarding color, texture, finish, and even watermarks to meet your unique requirements.
