Abstract
A system and method automatically determines appropriate font characteristics for different display mediums and different readability parameters in any language. A method includes determining font characteristics by receiving data including a font identifier and a language identifier, producing a representative line of type in the identified language and with the identified font, measuring characteristics of the representative line of type, and normalizing the measurements across a plurality of fonts and a plurality of languages. In an embodiment, an international translator is used to receive the data including the font identifier and the language identifier and the received data can include text in a language. The normalizing refers to widths of portions of the text called a “black river,” which is used to identify plotted measured characteristics to determine an average grayness across a perpendicular to a reading direction. The average grayness enables comparisons to pluralities of fonts and languages.
