Photography Sizes
The standard photographic print size is used in photographic photos. Unlike the ISO 216 paper sizes, the aspect ratio of photo printing will be different. In the international standard ISO 1008, millimeters are mainly used as the size measurement unit, but many countries use inches as the main unit of measurement. In the United States, size names are usually represented by codes in the nR format, where the number n represents the length of the short side (in inches). In the normal series, the long side is the length of the short side plus 2 inches (equal to or less than 10 inches) or 3 inches (equal to or greater than 11 inches). In Japan, size names are usually expressed in L, KG, and P format codes.
Below is a list of commonly used photography sizes.
