Foolscap folio

A comparison of the A4 and Foolscap folio papersize

Foolscap folio, commonly contracted to foolscap or cap or folio and in short FC, is paper made in or 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.
