The sequential units of language (i.e. words) have often been characterized by a tension between diversity and universality in the triangulation between information content, length and frequency. Here we examine similar tensions in the sequential units of visual narratives (i.e. panels) by focusing on how many entities appear per panel in visual narratives from the TINTIN Corpus of 1,030 annotated comics from 144 countries (76,000+ panels). Rates of entities per panel differ in regularized ways between styles of comics that cut across global regions, implicating typologically different ‘visual languages’. Entities per panel were also associated with panel size, where greater numbers of entities were associated with larger sizes of panels. Finally, a negative association appeared between panels with different numbers of entities and their frequency, reminiscent of a Zipf’s law of abbreviation. As associations of both size and frequency with character per panel persisted in a uniform way across styles, it implies universal tendencies transcending the diversity across systems, consistent with typological properties of languages.
