Postcard Size Photograph

From 1894 picture postcards were introduced (known as court cards) at 4.75 x 3.5 inches. This size is common up until 1899. In 1899 a standard postcard size of 5.5 x 3.5 inches was introduced as the maximum size. The minimum size was 3.25 x 2.25 inches.Postcards have been around nearly as long as postal services and are produced in a wide range of sizes, with some even being special shapes, for instance circular. However there are some recognised sizes for the "standard postcard".A real photo postcard (RPPC) is a continuous-tone photographic image printed on postcard stock. The term recognizes a distinction between the real photo process and the lithographic or offset printing processes employed in the manufacture of most postcard images.
