The effect of reading and teaching literary texts on the development of productive skills of language learners has long been an eye-catching factor for researchers. Having determined the interest through analysis, the present study seeks to search the effect of literary texts on the enhancement of vocabulary usage and composition length of the EFL learners. To achieve the above-mentioned desire, a case study was designed, including the population of 15 intermediate EFL. The case was chosen from the language learners of the Velayat University of Iranshahr. They were supposed to read and discuss a literary text, the effect of which on their writing was later compared to a previously prepared composition, before the exposure of the literary text. A focus on the vocabulary range and composition length along with the progression of their ideas in writing revealed that literary text and the discussion session were highly influential on the above-mentioned features. They used more lexical resources from the literary text in their composition along with a longer and more comprehensive text in terms of progression.
