The effects of three text layout variables-justification, line length, and leading, are examined. Text presented on computer display terminals is read faster when the text is left justified, characters are small, and lines are long and separated by blank space. Although each of the variables affects the efficiency of reading text and may also have affective consequences, the overall effect of each on learning outcomes may be negligible.
