This study investigates the effect of digital posters on the reading comprehension and engagement of EFL students. Thirty-three 3rd-year EFL college students were divided into a control group (n = 17) and an experimental group (n = 16). Both groups were pretested on reading comprehension and engagement before the experiment and then posttested after it. For 12 weeks, participants in the control group received their regular instruction while those in the experimental group used digital posters. Using digital posters went through six steps: orientation, preparation, production, presentation, evaluation, and reflection. While Mann-Whitney U Test showed no significant differences between the two groups in the pretest of reading comprehension (U = 118.00; p > 0.05) or engagement (U = 102.00; p > 0.05), it showed significant differences between them in the posttest of reading comprehension (U = 70.00, p < 0.05) and engagement (U = 57.00, p < 0.05). This led the researcher to reach the conclusion that digital posters significantly improved the reading comprehension and engagement of EFL students.
