Porträtformat

Porträtformat is a standard paper size used primarily for photographs, particularly portraits. It is defined by the International Organization for Standardization (ISO) as having a width of 100 mm and a height of 130 mm. This format is commonly used in photography, printing, and digital imaging to ensure consistency and compatibility across various devices and platforms.

The dimensions of Porträtformat are derived from the ISO 216 standard, which is part of a series of standards for paper sizes. The format is often referred to as "10R" in the ISO system, where "R" stands for "rectangular" and "10" indicates the size relative to other formats in the series. The aspect ratio of Porträtformat is 1:1.3, which is slightly wider than the standard portrait orientation of most photographs.

Porträtformat is widely used in professional photography, particularly for portraits and headshots. It is also commonly used in printing, such as for photo books, calendars, and greeting cards. In the digital world, Porträtformat is used for images on websites, social media, and other online platforms. The format is supported by most modern cameras, printers, and software, making it a versatile and widely accepted standard for photographers and designers alike.
