Use headings when a piece is long or has clear sections, like a report or dissertation. Short essays often use none at all. When you do use them, keep the levels consistent and format them to your referencing style.
When to use headings, and when not to
- Use them in reports, dissertations and long assignments with distinct sections.
- Usually skip them in short essays that flow as one continuous argument.
Always follow the brief. If the marker wants no headings, do not add them, even if they would help you. For longer work, see how to structure a dissertation and how to structure an assignment.
Heading levels
Think in levels. Level 1 is a main section, level 2 is a subsection inside it, level 3 is a sub point inside that. Keep the hierarchy logical and do not skip levels, so you never jump from a level 1 straight to a level 3.
How styles format headings
- APA: five heading levels with set formatting, such as a centred bold level 1 and a left aligned bold level 2. Check the current edition for the exact rules.
- MLA: no formal heading system. If you use headings, keep them short and consistent, and number them if it helps.
- Harvard: varies by institution. Usually bold, left aligned and consistent. Follow your department version.
- Chicago: does not prescribe headings tightly, so keep levels consistent. It is now in its 18th edition.
Styles update their editions, so check your department guide. The referencing styles explained post covers which style goes with which subject.
Make headings work for readers and search
- Use clear, descriptive wording rather than one word labels.
- Keep them parallel in style, for example all noun phrases or all questions.
- Use your word processor built in heading styles, so the contents page and navigation build themselves.
Before you submit
Numbered or unnumbered, pick one and be consistent. Make sure the heading style matches the referencing style you were told to use.
