2.1.2. Official Recognition
In 1995, the American National Standards Institute (ANSI) officially recognized letter, legal, and tabloid as the standard paper sizes in North America.
2.2. Development of ISO 216 Standard
The ISO 216 standard has its roots in the late 18th century and was formalized in the 20th century. It is based on a mathematical principle that allows for easy scaling and division of paper sizes.
2.2.1. Georg Christoph Lichtenberg’s Contribution
In 1786, German scientist Georg Christoph Lichtenberg proposed the idea of basing paper sizes on an aspect ratio of 1:√2. This concept laid the foundation for the ISO 216 standard.
2.2.2. Adoption of DIN Paper Format
In 1921, the German-born DIN paper format was adopted, with A4 being recommended as the standard paper size for business. This marked a significant step towards international standardization.
2.2.3. ISO 216 as the Official Standard
In 1975, ISO 216 became the official United Nations document format. By 1977, approximately 88 countries had already started using the A series.
