This work examines the issue of text legibility in the domain of graphic design – a field of art that has had a significant influence on the development of contemporary social communication. Due to the functional character of the letter, the aspect of legibility is a basic requirement for the realisation of the superior function of text, which is to convey content. For centuries, however, the letter has been entangled in a relationship between the message it carries and its visual representation, which when read, also satisfies the aesthetic needs of the recipient. Hence, the dichotomy of form and function.
