123ZollFormaten

123ZollFormaten is a catalog and framework of standard inch-based paper formats used in the printing and publishing industries. It provides a unified naming scheme and a reference table that lists each format by a numerical code, its width and height in inches, and its metric equivalents. The system aims to support international workflows by anchoring inch-based formats in German-speaking contexts, where the term Zoll (inch) remains common.

Common formats within 123ZollFormaten include Letter (8.5 by 11 inches, 216 by 279 mm), Legal (8.5 by 14 inches, 216 by 356 mm), Tabloid or Ledger (11 by 17 inches, 279 by 432 mm). It also covers smaller photo and card sizes such as 4 by 6 inches (102 by 152 mm) and 5 by 7 inches (127 by 178 mm), as well as 6 by 9 inches (152 by 229 mm). The list is designed to reflect typical industry use while allowing room for vendor-specific variants.

Naming and coding: In 123ZollFormaten each size is assigned a numeric code, aiding quick identification in templates, prepress software, and archive catalogs. The system provides cross-references to ANSI and common US formats to facilitate cross-border production and conversion.

Limitations and adoption: While widely used in certain German-speaking markets and legacy workflows, 123ZollFormaten is not a universal standard. It coexists with metric formats such as DIN A-series and with native ANSI sizes in the United States; successful use often requires conversion rules and clear documentation.
