A Series
A2
Belonging to the ISO 216 series, A2 paper size is a standard that's recognized globally. This format measures 420 x 594 millimeters or 16.54 x 23.39 inches, making it an ideal choice for various applications.
As part of the A-series, A2 is defined by an aspect ratio of √2:1. This unique characteristic ensures that when you cut or fold the paper in half along its longest side, you retain the same aspect ratio. It's this feature that makes the A-series so versatile and widely used across different industries.

A2 paper size finds its utility in a range of applications - from posters and diagrams to large-scale drawings and advertisements. Its generous dimensions make it perfect for designs that require ample space or need to capture attention from a distance.
In comparison with ANSI series (the American National Standards Institute), which uses letter instead of number designations, A2 is closest in size to ANSI C (17 x 22 inches). However, it's important to note that while both standards are used worldwide, ISO sizes are more prevalent outside North America.
One interesting fact about A2 paper size is its area calculation - exactly one-fourth of an A0 sheet or one-half of an A1 sheet. This consistency across sizes simplifies scaling images without distortion and contributes significantly to the popularity of this format.
Whether you're creating impactful marketing materials or detailed architectural plans, understanding and utilizing the benefits offered by A2 paper size can be instrumental in achieving your desired outcome.

Interesting facts about A2
1: A2 Paper Size
A2 paper is part of the ISO 216 standard series, which defines the sizes of paper used globally. It measures 420mm x 594mm or approximately 16.5 inches x 23.4 inches.
2: Proportional Dimensions
The dimensions of A2 paper are in a ratio of √2 (square root of 2). This means that if you divide the longer side by the shorter side, you will always get the same value, which is approximately 1.414.
3: Halving A1 Paper
A2 paper can be obtained by halving an A1 sheet along its longest side. Each subsequent size in the ISO series can also be obtained by halving its predecessor.
4: Commonly Used for Posters
A2 paper is commonly used for posters, architectural drawings, and diagrams that require a larger canvas than standard letter or legal-sized papers.
5: International Standardization
The ISO standard for paper sizes was first introduced in Germany in the early twentieth century and has since been adopted worldwide to ensure compatibility and ease of use across different countries and industries.
6: Historical Origins
The concept of using standardized paper sizes dates back to ancient China, where specific dimensions were assigned to different types of documents based on their importance and purpose.
7: A Series Continuity
The ISO A series includes various sizes from A0 (largest) to A10 (smallest), with each size being exactly half the area of its predecessor while maintaining the same aspect ratio.
8: A2 and Printing
A2 paper is compatible with most commercial printers and copiers, making it a popular choice for printing large-scale documents and designs.
9: Folding A2 to A3
An A2 sheet can be folded in half along its shorter side to obtain an A3 size. This folding technique allows for easy transition between different paper sizes without the need for cutting or trimming.
10: Global Adoption
The ISO paper size system, including A2, is widely used in countries such as Germany, France, the United Kingdom, Australia, and many others. It has become the standard for various industries worldwide.
