What is MLA Citation Style?

MLA Style is a set of rules for citing sources and formatting research papers.

You must cite sources with an in-text citation in the body of your paper and in a full citation in the Works Cited List at the end of your paper.

Margins: Add 1 inch margins on all sides.

Header (Individual papers): Starting with your first page, add your last name followed by page number (e.g., Chen 2) at the top right corner of the page. 

Title Page & Header (Group project): Include a title page if several students have written the paper. (See sample paper for example) Starting with your second page, add the students' last names followed by the page number at the top right corner of the page. If all last names do not fit in a single line in the header, you may just include the page number.

Line Spacing: Double-space your text.

Paragraph Alignment & Indentation: Indent the first line of each paragraph by 0.5 inch. Align your paragraphs to the left margin.

Font: Unless specified by your instructor, MLA recommends choosing an easy to read typeface set to 11 pt, 12 pt, or 13 pt. This includes:

  • Calibri
  • Arial
  • Times New Roman
  • Georgia
