About this series
ISO 216 covers most of the world, but it did not erase what came before, and it does not fit every local need. This hub gathers the national and historical sheet systems that still turn up on order forms, in art shops and in printer drivers. Each has its own section with the full size table.
Two systems are alive and official. Japan's JIS P 0138 keeps the ISO A sizes but uses its own larger B series (JIS B5 is 182 × 257 mm), alongside the traditional Kiku and Shiroku-ban book sizes. China's GB/T 148-1997 adopts ISO A and B and adds a D series (D4 is 188 × 260 mm, the common 16K exercise-book size) based on the traditional 787 × 1092 mm press sheet.
Two are Letter-family systems. Colombia and most of Latin America use Carta (216 × 279 mm) and Oficio (216 × 330 mm) with the Pliego (700 × 1000 mm) press sheet. Canada's P series (CAN 2-9.60M, 1976) was a metric rounding of Letter-based sheets, with P4 at 215 × 280 mm, and is now obsolete.
Two are historical sheet-name systems. The French AFNOR sizes, standardised in 1926, keep names such as Raisin (500 × 650 mm) and Jésus (560 × 760 mm) that are still used for art paper and posters. The British Imperial sizes, in use before Britain adopted ISO sizes, include Foolscap (343 × 432 mm), Crown, Demy and Royal, and gave the book trade its octavo names.
Finally, the transitional PA and F series are compromise sizes: PA4 (210 × 280 mm) fits inside both A4 and Letter, and F4 (210 × 330 mm) is the long foolscap sheet still sold across South-East Asia.
Questions about this series
Which countries do not use A4 or Letter?
Almost every country uses one or the other for office paper. The regional systems, such as JIS B in Japan, D sizes in China, Oficio in Latin America and F4 in South-East Asia, exist alongside A4 or Letter rather than replacing them.
What is 16K paper size?
16K is the Chinese exercise-book and office size, 188 × 260 mm in GB/T 148-1997 (D4). It is one sixteenth of the traditional 787 × 1092 mm press sheet and slightly smaller than A4.
What is Oficio paper size?
Oficio is the Latin American legal sheet, 216 × 330 mm (8.5 × 13 in) in Colombia, the same as US Government Legal or Folio. It is shorter than US Legal (355.6 mm). Some countries use a slightly different length.
What is foolscap paper?
Foolscap was the British office sheet before A4. The traditional foolscap folio is 203 × 330 mm (8 × 13 in); the full Foolscap sheet is 343 × 432 mm. The F4 sheet sold in South-East Asia (210 × 330 mm) is its modern descendant.
