Traditional Paper Sizes

These traditional paper sizes are mostly of British origin. They are quite obsolete in Britain today, replaced by the modern ISO paper sizes. Some of them are still used, at least informally, in the U.S.

This size information is based on Matt Roberts and Don Etherington, Bookbinding and the conservation of books: a dictionary of descriptive terminology. This reference, published by the U.S. government and not copyrighted, has been posted online by Stanford University. Some additional sizes are taken from the Brainy Encyclopedia web site.
