However, there are some logical correspondences between the sizes, noted below when applicable. Unlike ISO 216 paper sizes, the aspect ratios of photographic prints vary, so exact scaling of prints is not always possible. They do not match exactly the related sizes from ISO 216, like A6 for international standard postcards.

Japanese Chou sizes are for envelopes and Hagaki for postcards. A W suffix indicates sizes with an extended long edge, similar to the American S prefix.

The nP or cut ( 切り, kiri ) series are defined in reference to a full page size ( 全紙, zenshi ) of 457 × 560 mm, with smaller numbers (fewer cuts) indicating larger sizes. ( November 2019) ( Learn how and when to remove this template message) Please help improve this paragraph if you can. The specific problem is: The difference or equivalence between 4R, KG, PC, 10 × 15 and A6 (the international postcard size) should be made clearer. This paragraph may require cleanup to meet Wikipedia's quality standards. KG represents the size of a traditional 4 × 6 in (4R) Japanese postcard ( hagaki). The Japanese L is equivalent to 3R, while 2L-twice the size-matches 5R. In Japan, the same print sizes (and several additional ones) are known by different designations. The alternative Super series, denoted S nR, nR Plus or nR+, has an aspect ratio of 3∶2 (or as close as possible) and thus provides a better fit for standard 135 film (35 mm) at sizes of 8 inches or above.ĥR is twice the size of a 2R print, 6R twice the size of a 4R print and S8R twice the size of 6R.ĤD/6D is a newer size for most consumer level digital cameras and Micro 4/3 cameras Īmerican S8R or Japanese 6PW at 203 mm × 305 mm is the closest 3∶2 approximation to A4 at 210 mm × 297 mm (√2∶1). In the normal series, the long edge is the length of the short edge plus 2 inches (10 in or less) or 3 inches (11 in and above). In the US, size names are often denoted with a code of the format nR, where the number n represents the length of the shorter edge in inches.
