{{Short description|Photography paper sheet dimensions}}
Standard '''photographic print sizes''' are used in [[photographic printing]]. Cut sheets of paper meant for printing photographs are commonly sold in these sizes. 

Many nominal and effective sizes are specified in international standard<!--s--> '''ISO 1008'''<!--<ref name="iso1008"></ref> and 1009: paper rolls 89, 102, 127, 152, 203, 254, 279 (= 3.5, 4, 5, 6, 8, 10, 11-inch); 82.5 or 95 mm (= 3.25, 3.75-inch) wide--> 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&nbsp;in or less) or 3 inches (11&nbsp;in and above).  The alternative '''Super''' series, denoted '''S''n''R''', '''''n''R Plus''' or '''''n''R+''', has an [[aspect ratio (image)|aspect ratio]] of {{ratio|3|2}} (or as close as possible) and thus provides a better fit for standard [[135 film]] (35&nbsp;mm) at sizes of 8 inches or above.
5R is twice the size of a 2R print, 6R twice the size of a 4R print and S8R twice the size of 6R.
4D/6D is a newer size for most consumer level [[digital cameras]] and [[Micro 4/3]] cameras<ref>{{cite web|url=http://www.ritzpix.com/prints-enlargements/digital-prints/big-print-you |title= Big Print You, Unique Photo Sizes & Square Photos|website= www.ritzpix.com|publisher= [[Ritz Camera & Image]]|access-date= 2 June 2014|url-status= dead|archive-url=https://web.archive.org/web/20140626075832/http://www.ritzpix.com/prints-enlargements/digital-prints/big-print-you|archive-date= 26 June 2014}}</ref>
American S8R or Japanese 6PW at {{Times|203 mm|305 mm}} is the closest {{ratio|3|2}} approximation to [[A4 paper size|A4]] at {{Times|210 mm|297 mm}} ({{ratio|√2|1}}).

The sizes with 7 × {{frac|9|1|2}}, {{Times|12|16}} ({{ratio|4|3}}) and {{frac|9|1|2}} × 12 inches ({{ratio|5|4}}) 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 {{Times|4|6}}&nbsp;in (4R)<!--exact?--> Japanese postcard (''hagaki'').<ref>{{cite web |url=http://www.digiprishop.com/net/nedan.html|title= プリントサイズ/料金|website= www.digiprishop.com|publisher= PAM PhotoAnimationMovie Online Print|access-date= 7 July 2008|language= ja|trans-title= Print Size/Price|url-status= live|archive-url=https://web.archive.org/web/20081022081920/http://www.digiprishop.com:80/net/nedan.html|archive-date= 22 October 2008}}</ref>{{improve|paragraph|reason=The difference or equivalence between 4R, KG, PC, {{Times|10|15}} and [[ISO 216|A6]] (the international [[postcard]] size) should be made clearer.|date=November 2019}}
The '''''n''P''' or {{nihongo|cut|切り|''kiri''}} series are defined in reference to a {{nihongo|full page size|全紙|''zenshi''}} of {{Times|457|560}}&nbsp;mm, with smaller numbers (fewer cuts) indicating ''larger'' sizes.<ref>{{cite web|url=http://www.edsebooks.com/paper/miscjpaper.html|title= Traditional Japanese Specialty Papers|website= www.edsebooks.com|publisher= Editorial & Design Services Inc.|location= Tokyo, Japan|date= 15 January 2004|access-date= 2 June 2014|url-status=dead|archive-url=https://web.archive.org/web/20141201003326/http://www.edsebooks.com/paper/miscjpaper.html|archive-date= 1 December 2014}}</ref> 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.

== Overview ==

Unlike [[ISO 216]] 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 where applicable.

Many of the standard sizes are the same as [[sheet film]] [[Film format|formats]], and are appropriate for making contact sheets from these films.
