The gtk-paper-size instance handles paper sizes. It uses the standard called "PWG 5101.1-2002 PWG: Standard for Media Standardized Names" to name the paper sizes and to get the data for the page sizes. In addition to standard paper sizes, the gtk-paper-size structure allows to construct custom paper sizes with arbitrary dimensions.

The gtk-paper-size structure stores not only the dimensions (width and height) of a paper size and its name, it also provides default print margins.
