European Paper Sizes: Long Table
Version of 5 July 2007
home page
Some of the following paper sizes have been adopted by the International Organization for Standardization (ISO). Additionally, various national standards bodies recognize some of the paper sizes which the ISO omits.

The following numbers are rounded to four significant figures. Greater precision is of little use because practically all papers are made from cellulose, and consequently expand as they absorb moisture from the air, and contract as they release moisture. The most common rounding practice is to discard any fraction of a millimeter. For instance, 840.9 mm becomes 840 mm and 324.2 mm becomes 324 mm.

Manufacturers do not begin to offer all these sizes. The only ones seen with any regularity are:

One inch equals 25.4 millimeters.
