Will you print? Understand the measurements of A1, A2, A3, A4, A5 and other papers 14z2t

Although we live in a digital world, printed materials are still part of our daily lives. And when printing that pamphlet, banner, or even a document, it is important to know what the paper measurements that we will use. 28432r

Have you ever wondered why these standards were set? Or even who had the idea to name and measure all the sheets? In this article we explain the origin of all these patterns that are widely used to print various publications.

A little history 31i1v

In 1768, the German writer, philosopher and mathematician Georg Christoph Lichtenberg I thought the paper measurements very different, and began to think of a standardization that would leave everyone else's lives easy. The scholar thought that if all the leaves had the same ratio, they could be folded without problems that could influence the content of the work. The aspect ratio of the sides of the paper would be the same regardless of size.

Lichtenberg cited his plan in a letter to Johann Beckman the same year he decided to develop standardization, and, at the beginning of the XNUMXth century, Walter Portmann put into practice the idea of ​​the German scientist. porstmann standardized all paper sizes, with a standard introduced by DIN, in 1922. This would give rise to a wide variety of formats that were used at the time.

A DIN ( Deutsches Institut fur Normung eV) and the organization da  which standardizes various techniques and is located in Berlin. If we translate the name into Portuguese, it becomes: German Institute for Standardization. This organization can be classified as a “German ABNT”, as it is also responsible for the standardization of norms and techniques used in several areas. 

Fast acceptance in many countries around the world 2s106k

A FROM 476, the standardization of paper measurements published in 1922, was quickly adopted by several countries. Before Second World War, it started to be used by:

• Belgium (1924);
• Netherlands (1925);
• Norway (1926);
• Switzerland (1929);
• Sweden (1930);
• Soviet Union (1934);
• Hungary (1938);
• and Italy (1939).

During the war, Uruguay (1942), Argentina (1943) and Brazil (1943) also adopted the standard standard in . After the agreement for the battles is over, the DIN 476  became even more popular. Several countries started to use the new standard of paper measures, see:

• Spain (1947);
• Austria (1948);
• Romania (1949);
• Japan (1951);
•  Denmark and Czechoslovakia (1953);
• Israel and Portugal (1954);
• United Kingdom and Yugoslavia (1956);
• India and Poland (1957);
• Venezuela (1962);
• New Zealand (1963);
• Iceland (1964);
• Mexico (1965);
• South Africa (1966);
• , Peru and Turkey (1967);
• and Chile, along with Greece (1968).

In the following years, other nations also adhered to the new standardization, such as:

• Zimbabwe and Singapore (1970);
• Bangladesh and Thailand (1972);
• Barbados (1973);
• Australia and Ecuador (1974);
• and Colombia and Kuwait (1975).

A DIN 476 became so popular that it was established as the standard ISO in 1975, and also as the official documentation format for United Nations. A DIN 476 then it would be called ISO 216.

The ISO 216 standard and a brief surprise 1m1r41

A ISO is an independent international non-governmental organization, which has 162 national standards bodies. ABNT e DIN are part of the conglomerate, and basically all of them come together to develop standards based on consensus and the current world market situation. All approved rules innovation and provide solutions to global challenges.

As we said above, the ISO 216 was approved in 1975, and it was created to definitively standardize the DIN 476. He defined that all countries participating in the organization would have to use the same paper sizes, as everyone understood that this would be useful to facilitate  resizing documents between their sizes, as they all have the same aspect ratio. This also prevents loss of image quality.

But  EUA e Canada didn't like all these imposed rules and chose stationery as the default ( US letter). Countries like Philippines, Mexico e Colombia adopted to ISO 216, but the use of stationery (216mm × 279mm) is still quite common.

For the nations that accepted standardization, they would all have to produce and distribute only what was within what was agreed upon. The most common of these is A4 (standard size of sulfite sheets), but others also exist.

Note that the higher the number the name gains, the smaller the size of the sheet. For a while, EUA e Canada  are not yet adept at the standard, which can already be considered worldwide, and for the time being there are no indications that the two North American countries will adhere to the ISO 216.

But this was not a problem for the pattern to become famous in American or Canadian territory, as image editing and even diagramming programs that have North American origin (Photoshop e InDesign) are based on these sheet sizes.

Standardization in paper measurements was great for everyone 114d71

The idea of ​​several countries ing together for standardization in paper measurements it was quite an action intelligent, because in this way the work of several professionals can be more easy. It would not be necessary to work on a project and then change its settings to another paper size.

And even if you have to change the paper, the measurements of all sizes used in the pattern ISO 216 allow an easy adaptation of the documents. It remains to be seen if EUA  e Canada will the rest of the world and enter the standard for good, or will they continue using the already known US Letter. This action does not influence the reputation of the two countries, but it would be convenient for them to globalize the works produced there. that would bring improvements for all.
