Standard photographic print sizes are used in
photographic printing
Photographic printing is the process of producing a final image on paper for viewing, using photographic paper, chemically sensitized paper. The paper is exposed to a photographic Negative (photography), negative, a positive reversal film, transpa ...
. Cut sheets of paper meant for printing photographs are commonly sold in these sizes.
Many nominal and effective sizes are specified in international standard ISO 1008 using millimeters only, although most are clearly derived from integer-inch lengths. They are highlighted in the table below.
United States
In the US, size names are often denoted with a code of the format ''n''R, where the number ''n'' represents the length of the shorter edge in inches. 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). The alternative Super series, denoted S''n''R, ''n''R Plus or ''n''R+, has an
aspect ratio of (or as close as possible) and thus provides a better fit for standard

The sizes with 7 × , () and × 12 inches () are used for black-and-white paper.
Japan
In Japan, the same print sizes (and several additional ones) are known by different designations. The Japanese L is equivalent to 3R, while 2L—twice the size—matches 5R. KG represents the size of a traditional in (4R) Japanese postcard (''hagaki'').
The ''n''P or series are defined in reference to a of mm, with smaller numbers (fewer cuts) indicating ''larger'' sizes.
A ''W'' suffix indicates sizes with an extended long edge, similar to the American ''S'' prefix.
Japanese ''Chou'' sizes are for envelopes and ''Hagaki'' for postcards. They do not match exactly the related sizes from ISO 216, like A6 for international standard postcards.

Unlike

ISO 216 is an international standard for paper sizes, used around the world except in North America and parts of Latin America. The standard defines the "A", "B" and "C" series of paper sizes, including A4, the most commonly available paper size ...
paper sizes, the aspect ratios of photographic prints vary, so exact scaling of prints is not always possible. However, there are some logical correspondences between the sizes, noted below when applicable.
