- 2. What are the International standard paper sizes?
Standard paper sizes like ISO A4 are widely used all over the world today. This text explains the ISO 216 paper size system and the ideas behind its design.
The ISO paper size concept
In the ISO paper size system, the height-to-width ratio of all pages is the square root of two (1.4142 : 1). In other words, the width and the height of a page relate to each other like the side and the diagonal of a square. This aspect ratio is especially convenient for a paper size. If you put two such pages next to each other, or equivalently cut one parallel to its shorter side into two equal pieces, then the resulting page will have again the same width/height ratio.
The ISO paper sizes are based on the metric system. The square-root-of-two ratio does not permit both the height and width of the pages to be nicely rounded metric lengths. Therefore, the area of the pages has been defined to have round metric values. As paper is usually specified in g/m², this simplifies calculation of the mass of a document if the format and number of pages are known.
ISO 216 defines the A series of paper sizes based on these simple principles:
- The height divided by the width of all formats is the square root of two (1.4142).
- Format A0 has an area of one square meter.
- Format A1 is A0 cut into two equal pieces. In other words, the height of A1 is the width of A0 and the width of A1 is half the height of A0.
- All smaller A series formats are defined in the same way. If you cut format An parallel to its shorter side into two equal pieces of paper, these will have format A(n+1).
- The standardized height and width of the paper formats is a rounded number of millimeters.
For applications where the ISO A series does not provide an adequate format, the B series has been introduced to cover a wider range of paper sizes. The C series of formats has been defined for envelopes.
- The width and height of a Bn format are the geometric mean between those of the An and the next larger A(n−1) format. For instance, B1 is the geometric mean between A1 and A0, that means the same magnification factor that scales A1 to B1 also scales B1 to A0.
- Similarly, the formats of the C series are the geometric mean between the A and B series formats with the same number. For example, an (unfolded) A4 size letter fits nicely into a C4 envelope, which in turn fits as nicely into a B4 envelope. If you fold this letter once to A5 format, then it will fit nicely into a C5 envelope.
- B and C formats naturally are also square-root-of-two formats.
The following table shows the width and height of all ISO A and B paper formats, as well as the ISO C envelope formats. The dimensions are in millimeters:
A Series Formats B Series Formats C Series Formats 4A0 1682 × 2378 – – – – 2A0 1189 × 1682 – – – – A0 841 × 1189 B0 1000 × 1414 C0 917 × 1297 A1 594 × 841 B1 707 × 1000 C1 648 × 917 A2 420 × 594 B2 500 × 707 C2 458 × 648 A3 297 × 420 B3 353 × 500 C3 324 × 458 A4 210 × 297 B4 250 × 353 C4 229 × 324 A5 148 × 210 B5 176 × 250 C5 162 × 229 A6 105 × 148 B6 125 × 176 C6 114 × 162 A7 74 × 105 B7 88 × 125 C7 81 × 114 A8 52 × 74 B8 62 × 88 C8 57 × 81 A9 37 × 52 B9 44 × 62 C9 40 × 57 A10 26 × 37 B10 31 × 44 C10 28 × 40
The ISO standard paper size system covers a wide range of formats, but not all of them are widely used in practice. Among all formats, A4 is clearly the most important one for daily office use. Some main applications of the most popular formats can be summarized as:
A0, A1 technical drawings, posters A1, A2 flip charts A2, A3 drawings, diagrams, large tables A4 letters, magazines, forms, catalogs, laser printer and copying machine output A5 note pads A6 postcards B5, A5, B6, A6 books C4, C5, C6 envelopes for A4 letters: unfolded (C4), folded once (C5), folded twice (C6) B4, A3 newspapers, supported by most copying machines in addition to A4 B8, A8 playing cards
