A Series Paper Size Areas – A0, A1, A2, A3, A4, A5, A6, A7, A8, A9, A10; Billboard Sizes/Dimensions – Including Multisheet Billboards; Other Paper Sizes Found In Japan. Apart from Shirokuban and Kiku, people use many other paper sizes in Japan. The popular ones like the AB format, which has a short side of A4 and the longer side of B5.
In 1996, the American National Standards Institute adopted ANSI/ASME Y14.1 which defined a regular series of paper sizes based upon the de facto standard 8 1⁄2 in × 11 in (216 mm × 279 mm) Letter size which it assigned "ANSI A", intended for technical drawings, hence sometimes labeled "Engineering".
Sizes marked with a Y are supported by sending the paper dimensions in millimeters to the printer. Sizes that refer to another size substitute the referred size when paper size matching is turned on. If paper size matching is not turned on, the behavior depends upon the specific driver. To turn on paper size matching, use this INI option
The dimensions of the C series sizes are defined by the ISO 269 paper size standard. The C series is most commonly used for envelopes. The area of C series paper is the geometric mean of the areas of the A and B series paper of the same number. For example, C4 has a bigger area than A4, but smaller area than B4.
