How to Capitalize Headings and Titles

In Brief...

Business documents are often broken up into sections for clarity and organization. Each of those sections will have a title, heading, or subheading. There are correct formats regarding capitalization for these titles and headings. Just follow these simple rules.


  1. Capitalize the first word of the title or heading.
  2. Capitalize the last word of the title or heading.
  3. All other words are capitalized unless they are conjunctions (and, or, but, nor, yet, so, for), articles (a, an, the), or prepositions (in, to, of, at, by, up, for, off, on).
    • According to the Chicago Manual of Style and the Modern Language Association (MLA) Handbook, no prepositions (regardless of length) are capitalized unless they are the first or last word of the title or heading.
    • The Gregg Reference Manual: is a bit more specific: Capitalize all words of four or more letters.
    • Be sure to check to see which style manual the company is following, assuming they do follow one. If they are using Chicago or MLA, you would not capitalize prepositions like "through" and "after." If they use Gregg, both of those prepositions would be capitalized. There are other style manuals that may have different rules, so be sure to find out what the preferred style is for your business.
