Created by the American Psychological Association, the APA style of formatting is most commonly used in college level papers and in the field of social sciences. While writing a dissertation or thesis, it is important that students follow the formatting style mentioned by their university. The APA style of formatting ensures consistency in the content and easy readability. APA style requires you to write your content in 12 point size Times New Roman font with one inch margins on each side. Each section of your paper has particular guidelines that must be followed so that you don’t lose out on marks only because of a formatting error.
