About DIN-Formate.info

Who is behind the site

DIN-Formate.info went online in 2010 as a project by bwave, starting with an overview of the DIN series and a few converters. Since 2026 it has been run by kōdōkalabs in Munich. For the relaunch we recalculated every table, checked every figure against standards and primary sources, and added printing, packaging, ten calculators and this English edition.

The name stays German because “DIN-Formate” is what people in Germany call ISO paper sizes. The English pages are written for readers in the UK, Ireland and anywhere else that uses A4, with notes for North American readers wherever Letter and inches come into play.

How we work

Sources

All dimensions come from the current standards (ISO 216, DIN 476-2, ISO 217 and others) and are checked against further sources. We list the main ones under sources.

Calculation

Tables in centimetres, inches and pixels are calculated from a single checked data table, so no typo can creep in between pages.

Keeping up to date

Information that can change, such as postage rates, carries a date and is reviewed regularly.

Corrections

If you find a mistake, tell us. We check every report and correct the page if it is right.
