Like all developments throughout history, typography owes its development to experimentation. Experimental studies on the discipline of writing have brought typography to the present day. What will carry it to the future will be experimental studies. Experimental studies have opened the door to new forms of expression. One of these forms of expression is the work produced on the basis of modules. Although modular typography is diversified with different methods, the type discussed in this article is modular studies with unit repetition. Experimental studies that developed by different designers and design studios for the projects are presented to the reader. The module-based typographic studies used in these works were examined and the ability and effect of modular typography in conveying messages were questioned. In the light of the results obtained, answers were sought to the questions of diversity in the selected modules, compatibility between the module and the written word or words, and the contribution of different module trials to the practice. The research was supported by a literature review. The importance of the research is that the existence of modular typography among experimental typography works becomes evident, that it is noticed by more designers who are interested in typography, and that modular typography is encouraged to be tried by designers and design students.
