foolscap

Once upon a time, before A4 and Letter became common, there was foolscap. Despite the name, it was not an insult. It was a traditional size of writing paper, especially common in Britain and other places that followed British usage. The name came from an old watermark that showed a jester's cap.

Think of it as a taller cousin of modern office paper. A full sheet was often around 13 by 16 or 13.5 by 17 inches, and when folded it made the long, narrow page shape often linked with older legal papers and handwritten documents. If you were a clerk in the 19th century, you might well have spent your day writing on sheet after sheet of it.

Foolscap is a historical term for a traditional size of writing or printing paper. It was widely used for office work, schoolwork, manuscripts, and legal papers, especially in Britain and in countries influenced by British paper standards. The name did not come from "foolish" writing or scraps. It came from an early watermark that showed a fool's cap, meaning a jester's hat, printed into the paper.

The exact size varied by place and period. A full sheet was commonly about 13 by 16 inches or 13.5 by 17 inches. When folded, it produced a long page often called foolscap folio, roughly around 8 by 13 inches or 8.5 by 13.5 inches. That shape made it useful for formal writing and record-keeping, and it is one reason the word often appears in older books, archives, and legal contexts.

Today, the term feels old-fashioned in most everyday settings. As A4 and other modern standard sizes took over, foolscap became far less common. Now you are most likely to meet the word in classic literature, historical records, old office stories, or discussions of traditional stationery.
