Dimensions of A Series Paper Sizes
The dimensions of the A series paper sizes are detailed according to the ISO 216 standard, which can be found in the accompanying table below the diagram. These dimensions are presented in both millimeters and inches, allowing for quick conversion to centimeters by simply dividing the millimeter value by 10. The A Series paper size chart, positioned below to the left, provides a visual representation illustrating the relationship between different sizes. For instance, an A5 sheet is precisely half the size of an A4 sheet, and similarly, an A2 sheet is half the size of an A1 sheet. This systematic halving continues throughout the series, demonstrating a logical and standardized approach to paper sizing that facilitates easy scaling between different dimensions for various applications.

To convert paper sizes to centimeters, you can simply divide the millimeter values by 10. Similarly, to determine the size in feet, divide the inch values by 12. This straightforward conversion method allows for an easy calculation across different units of measurement, ensuring that you can quickly adapt dimensions to suit various needs, whether for academic, professional, or personal use.
4A0 & 2A0 – The DIN 476 Oversize Formats
The 4A0 and 2A0 paper sizes, which are larger than the standard A0, are not officially recognized by ISO 216 but are frequently used for oversized documents. These formats have their roots in the German DIN 476 standard, which served as the foundational document for the ISO 216 standard. The size 2A0 is occasionally referred to as A00; however, this nomenclature is not applied to the 4A0 size. These oversized formats are commonly utilized in applications requiring large-scale printing, such as architectural plans and detailed large-format diagrams.

The ISO 216 Standard for Paper Sizes
The international standard for paper sizes, known as ISO 216, is a widely recognized and adopted system that plays a crucial role in various industries and applications worldwide. This standard, developed by the International Organization for Standardization (ISO), provides a comprehensive framework for defining the dimensions of standardized paper formats, ensuring consistency, compatibility, and efficiency in paper-based processes.
The foundation of the ISO 216 standard is the A series of paper sizes, which forms the primary set of dimensions. However, the standard also includes the complementary B series and C series, each serving a specific purpose and catering to different needs.
The Importance of the ISO 216 Standard
The ISO 216 standard for paper sizes has become a globally recognized and widely adopted system, with its principles and dimensions used in various industries and applications worldwide. This standardization provides numerous benefits, including:
- Compatibility and Interoperability: The ISO 216 standard enables seamless integration and exchange of documents across different devices, software, and workflows, as it ensures compatibility of paper-based materials.
- Efficiency in Printing and Document Handling: The consistent aspect ratio and progressive doubling of dimensions in the A series, B series, and C series facilitate efficient printing, copying, scanning, and document management.
- Cost Optimization: The standardized paper sizes allow for the optimization of paper usage, storage, and transportation, ultimately reducing costs and waste.
- Global Harmonization: The widespread adoption of the ISO 216 standard fosters global harmonization in paper-based processes, enabling seamless collaboration and communication across different regions and industries.
- Historical Significance: The ISO 216 standard builds upon the early efforts of pioneers in the field of paper standardization, such as the German bookbinder Georg Christoph Lichtenberg, who proposed the concept of standardized paper sizes in the late 18th century.
The ISO 216 standard continues to be an essential tool in the digital age, as it provides a common language and framework for managing paper-based workflows, despite the increasing digitization of various processes. Its adaptability and relevance have ensured its enduring significance in the ever-evolving world of document management and communication.
