Tamaños de papel A0, A1, A2, A3, A4, A5, A6, A7, A8, A9, A10

The measurements of the A series paper formats (A0, A1, A2, A3, A4, A5, A6, A7, A8, A9, A10) were created at the beginning of the 20th century under the name of DIN 476 or DIN A . currently the formats are kept under the ISO 216 standard.

Series A or DIN A begins with the A0 format, which has a measurement close to one square meter. From there, the following formats will be half of the previous measure. This means that the size A1 is half of A0, A2 is half the size of sheet A1, and so on.

In the opposite direction, each sheet format measures twice the size that follows it. That means that A9 is twice the size of A10, A4 is twice the size of A5, etc.

Currently, formats ranging from A0 to A3 are used in the printing and advertising industry to make posters , while A3 to A5 formats are often used in the publishing industry to make brochures, books, magazines and stationery. . While the smaller formats A7 to A10 are used to make cards.

Why is series A called DIN A or ISO 216 standard?

Series A sheet sizes are used almost all over the world except in Canada, the United States, and most Latin American countries. In these countries the letter, legal, legal and tabloid sizes are used, which belong to the American system of measurements.

The rest of the world uses the ISO 216 standard, which in turn comes from the DIN 476 format, created after the First World War to standardize paper measurements. This is where the A series comes from, also known as DIN A or fundamental series.

The importance of the DIN A series is that the rest of the measurements used in the graphic industry are obtained from there. In addition, these measurements are the most used in the world because they are those of the paper used in photocopiers and printers, office supplies, envelopes, posters, etc., so they are a reference.

Although the measurements between the American standard (which includes letter, letter , folio and tabloid size) and the ISO 216 format are very different from each other, in many cases A4 sheet and letter size paper are considered similar, although really they are not. This is especially useful when using copiers and printers.
