CMS provides detailed information on formatting a manuscript to be sent to a publisher. It does not address formatting of student papers, so it important to find out whether your instructor has specific requirements when you are writing a paper.
Basic elements of a paper using Chicago style are as follows:
Margins, Indents
Spacing
Fonts: CMS does not specify a particular font. We suggest you use a readable serif font, like Times New Roman, 12 pt.
