This research analyzed the factors that influenced the reading comprehension of twelfth-grade students at SMKS Dinamika Kotabumi based on text characteristics. Using a qualitative descriptive method, data were collected through structured interviews and closed questionnaires with six students with high reading abilities. The research results showed that the factors influencing reading comprehension included mastery of vocabulary, understanding of grammar, and the relationship between reading themes and students' experiences. Of these factors, understanding grammar had the greatest influence on reading comprehension, as students with a better understanding of grammar were able to understand texts more easily than those with limitations in this aspect.
