Abstract

Writers often simplify texts using various readability formulas to ensure clear communication with the audience. The idea that readability gauges how easily a text is understood and its accessibility to readers is essential in designing educational materials. In effect, readability indices classify texts in levels and align them with learners’ linguistic competence. This study compares three classic readability formulas: Flesch Reading Ease (FRE), Flesch-Kincaid Grade (FKG), and the Gunning Fog Index (GFI) to examine their applicability and text complexity. Text-Inspector and Complete Lextutor software online programs assess the readability and vocab-profile of (a) academic (b) non-academic, and (c) entertainment texts. Research outcomes report that the academic text was highly difficult (FRE=37.62), the non-academic text had a standard difficulty (FKG=68.11), and the entertainment text was easy to read (GFI=89.51). These results indicate that the three formulas show significant metric approximations, closely linked to intuitive text processing methods. In conclusion, the functionality of these readability formulas illustrates how readability metrics and vocab-profile indices, to some extent, categorized texts in advance, intermediate or elementary, conditioning readers’ comprehension and interpretation of the text. It also provides insights into the type of genre and level of the reader’s proficiency to whom the text is focused.
