Guide to International Paper Sizes

Concise Tables of Measurements

To ensure accurate, economical printing when publications designed or typeset in one country are printed in a second country, it is necessary to know the standard paper sizes used in the second country. Because designers and publishers often do not have ready access to this information, EDS Inc., Editorial & Design Services, has published this concise guide, consisting of the four tables listed below. For additional sizes and complete inch-metric equivalents, see Expanded Tables of North American and UK/EU Paper Sizes and Japanese Papers for Printing. For office and business papers, see Desktop/Office Printer, Business & Imposetter/Large-Format Papers. See International Paper Sizes for additional information of interest to transnational publishers.

Feedback and experience suggest that ISO (International Organization for Standardization) paper sizes--based on the earlier DIN (Deutsche Industrie Norm) sizes--are commonly used everywhere in the world except Canada and the United States. For an admirable explanation and summary of ISO paper-size standards, see Markus Kuhn's International Standard Paper Sizes Web page.

Japan has developed its own standards for paper sizes. While the JIS (Japan Industrial Standard) A series of sizes is identical to the ISO/DIN A series of sizes, the JIS B series is not identical to the ISO B series; and Japan has no series of envelope sizes comparable to the ISO/DIN C series.

In addition to ISO/DIN paper sizes, metricated traditional paper sizes are commonly used in some countries (e.g., Japan) and regions (e.g., the European Union).

ISO and JIS Standard Paper Sizes
Trim sizes in mm; Width precedes height; Press-sheet
sizes accommodate 3 mm head, foot, and fore-edge trim margins;
To convert to approximate decimal inches, divide measures by 25.4, or see
Expanded Tables of North American and UK/EU Paper Sizes
and Japanese Papers for Printing for appropriate tables.
