General CMS Guidelines

• Margins should be set at no less than 1” and no greater than 1.5”. 
• Typeface should be something readable, such as Times New Roman or Palatino. 
• Font size should be no less than 10 pt. (preferably, 12 pt.). 
• Text should be consistently double-spaced, with the following exceptions: 
  • Block quotations, table titles, and figure captions should be single-spaced. 
    • A prose quotation of five or more lines should be blocked. 
    • A blocked quotation does not get enclosed in quotation marks.  
    • An extra line space should immediately precede and follow a blocked quotation. 
    • Blocked quotations should be indented .5” as a whole. 
• Notes and bibliographies should be singled-spaced internally; however, leave an extra line space between note and bibliographic entries. 
• Page numbers begin in the header of the first page of text with Arabic number 1. 
• Subheadings should be used for longer papers. 
  • CMS recommends you devise your own format but use consistency as your guide. 
    • For Turabian’s recommendations, see “Headings,” below. 
• Put an extra line space before and after subheadings, and avoid ending them with periods.
