Paper size historically common in some parts of Europe, and former British territories

Foolscap folio, commonly contracted to foolscap or cap or folio and in short FC, is paper cut to the size of 8.5 × 13.5 in (216 × 343 mm) for printing or to 8 × 13 in (203 × 330 mm) for "normal" writing paper (foolscap). This was a traditional paper size used in some parts of Europe, and the British Commonwealth, before the adoption of the international standard A4 paper.

Historically, there were two prevalent foolscap folio paper sizes: British foolscap and imperial foolscap. The British foolscap measured approximately 8.0 by 13.0 inches (203 mm by 330 mm) and was widely used in the United Kingdom for official documents and administrative records. On the other hand, the imperial foolscap was slightly larger, measuring around 8.5 by 13.5 inches (216 mm by 343 mm). This larger format was preferred in some regions of the British Empire for similar purposes. Both paper sizes represented an era when handwritten records and official documentation were prevalent, but they have since faded into history, replaced by contemporary paper standards.

Foolscap was named after the fool's cap and bells watermark commonly used from the 15th century onwards on paper of these dimensions. The earliest example of such paper was made in Germany in 1479. Unsubstantiated anecdotes suggest that this watermark was introduced to England in 1580 by John Spilman, a German who established a papermill at Dartford, Kent. The general pattern of the mark was used by Dutch and English papermakers in the late 17th and 18th centuries, and as early as 1674 the term "foolscap" was being used to designate a specific size of paper regardless of its watermark. Apocryphally, the Rump Parliament of 1648–1653 substituted a fool's cap for the royal arms as a watermark on the paper used for the journals of Parliament. According to the Oxford Dictionary of Word Origins, there is no basis in fact for this statement. efn|Charles I was executed on 30 January 1649, which would have been the cause of this supposed change. There were only around 40 mills making hand made paper in England between 1601 and 1650, with 23 of them within 30 miles of London. It appears that the manufacture of white paper in England had come to a halt in around 1641, perhaps because of the lack of a linen industry for raw materials, and more likely because of the impact of the troubled times leading to the Civil War. The French had become the most prominent supplier of white paper from around 1600 to 1675, when the Dutch took over. and is named (locally) oficio ('official').

Today in the United States, a half foolscap sized paper for printing is standardized to , widely available and sold as "legal sized paper" for printing, writing, note taking etc. A full foolscap size paper of is also widely available for arts and crafts etc. alongside the tabloid size.
