This paper presents users' preferred line length and its effect to user performance when they read Chinese technical text. A web-shaped software is developed to record user behaviors. The participants are asked to adjust the length of the text until they feel comfortable with. The study includes two tasks, pre-reading task and while-reading task. In pre-reading task, participants adjust the line length and stop at their preferred line length; while-reading task record user's further adjusted line length when they are reading. The study shows that 76 CPL (character per line) is the preferred line length with a good score and task-solving efficiency. This finding can be used to help decide the line length for Chinese technical text.
