Typographic features of text. Outcomes from research and practice

This paper provides a comprehensive review of literature on the legibility of printed text in order to provide informed guidance on the design and preparation of typographic materials. To this end, experimental findings are taken into account, as well as the perspective of typographers, graphic designers, and authors. First, the typographic features of text are reviewed and illustrated individually to identify all the features that specifically characterise text layouts. It is emphasised, however, that the various typographic features should be selected in relation to each other, and that it is the combination and manipulation of all these typographic features as a group that makes the text legible. Studies are then reviewed and illustrated on the typographic structure of text as a whole. This information will prove useful to anyone involved in the development of typographic materials, including typographic and graphic designers, teachers and students.
