Some facts#

  • There are many paper size standards, varying depending on application and region.
  • Examples of existing standards are:
    • ISO 216 standard - defines the so-called A serie (A0, A1, A2, A3, ...) and B serie (B0, B1, B2, B3, ...), which are created by successively dividing the previous format into two equal parts. Notebooks in A4 (210 × 297 mm) and A5 (148 × 210) are widely known in Europe. Sometimes these formats are called net formats because they can be obtained by trimming slightly larger formats of the RA or SRA series (so-called gross formats),
    • ISO217 standard - adds the series RA (raw format A) and SRA (supplementary raw format A), so-called gross formats. These formats are large enough to be able to obtain the net formats after trimming,
    • ISO269 standard - introduces a C serie (C0, C1, C2, C3, ...) used for envelopes,
    • ANSI / ASME Y14.1 standards - a collection of different formats used in the United States,
    • Arch standard - a series of formats (Arch A, Arch B, Arch C, ...) intended for architectural applications,
    • CAN 2-9.60M standard - a series of Canadian formats (P1, P2, P3, P4, ...) intended for correspondence (P stands for paper sizes for correspondence),
    • JIS standard - set of formats used in Japan (B0, B1, B2, B3, ...),
    • etc.

    • Country ISO codes - two-letter country ISO 3166-1 and three-letter ISO 3166-2 codes (e.g. us and USA for United States),
    • Currency ISO codes - unified ISO 4217 currency codes ready for international settlements (e.g. USD for american dollar),
    • Paper size - paper sheet size standards: ISO 216, ISO 217 and ISO 269 (e.g. A4 format),
    • ISO 8859-2 (Latin-2) table - obsolete character encoding standard ISO 8859-2 extending ASCII table with local diacritical characters (e.g. in the Polish word łabędź), currently supplanted by UTF-8.
