Further Information

When the United Kingdom started using ISO sizes, the traditional paper sizes were no longer commonly used. Most of the traditional sizes were used in the production of books, and were never used for other stationery purposes. ‘Folio’ or ‘Foolscap’ is an alias for Foolscap Folio, as is ‘Kings’ being an alias for ‘Foolscap Quarto’.
