Paper sizes

There are two major classifications of paper measurements:

  • European format : series A, B and C of the ISO 216 standard.
  • American format : letter, legal and tabloid size.

The European format is the most used in almost the whole world, and while the American format is especially popular in some countries of the American continent.

The standardization of paper dimensions helps to unify production and printing criteria, and at the same time serves as a guide for professionals in related industries, such as publishing, advertising, or office supplies.

Series A paper size

The most widely used measure of paper in almost all the countries of the world is series A, known as the fundamental series, because other measures are derived from it. These are the sheet sizes:

Letter, legal and tabloid size

In the United States, Canada and some Latin American countries, other paper formats other than series A are used, called letter, office, letter and legal, included within the traditional American system of measurements.

These page measures are used especially for letter and document writing purposes. These are its dimensions:

Paper sizeMillimetersCentimetersInches
American systemPaper220 x 280 mm22 x 28 cm8.6 x 11 inches
Job220 x 340 mm22 x 34 cm8.6 x 13.3 inches

Tabloid279,4 x 431,8 mm27,9 x 43,1 cm11 x 17 inches

Since letter and letter sizes have similar measurements, it is common for them to be used interchangeably. The same occurs with legal and legal size, hence, although it is not an explicit rule, the formats of the Anglo-Saxon system are usually reduced to letter and legal size for practical purposes.

On the other hand, the tabloid size is the one used in the production of many printed newspapers in the American continent.

Paper dimensions according to ISO 216

There is a notable difference between the A-series sizes, which are the most widely used in the world, and the sheet sizes that are used in much of the American continent. The reason for this difference is the DIN 476 standard, created in Germany by engineer Walter Porstmann in 1917.

The objective of this first standardization was to use as much paper as possible. As the measures turned out to be efficient, they were maintained over time, hence when the International Organization for Standardization (ISO) decided to establish the dimensions of the different paper formats, they simply adhered to the measures established in DIN 476, considered the pioneering standard.

Currently, the ISO 216 standard is used almost everywhere in the world, with the exception of Canada, the United States, most of the Central American countries, Venezuela, Colombia and Chile. in which the letter, legal , letter, legal and tabloid sizes of the American system are used instead of their series A equivalents.
