In academic writing, formatting a header for research paper submissions requires distinguishing between two distinct structural elements: the page header (the running head and page number positioned in the top margin) and section headings (the hierarchical titles that organize internal text). Conflating these two components is one of the most common causes of formatting defects during editorial triage and peer review. Style manuals—including the American Psychological Association (APA 7th Edition), the Modern Language Association (MLA 9th Edition), and the Chicago Manual of Style (17th and 18th Editions)—prescribe precise, non-negotiable rules for margin placement, capitalization, font matching, and subsection hierarchy.
Whether you need to format a header in research paper drafts for coursework or configure a heading for research paper manuscripts for journal submission, this guide provides the authoritative rules, comparative tables, annotated examples, and verification steps necessary to satisfy editorial standards.
Purpose of the section
Both page headers and section headings serve vital, complementary functions in scholarly communication and document processing:
- Page Header (Running Head): Establishes manuscript identity, continuity, and pagination. In multi-page physical manuscripts or detached digital pages, the page header ensures that every leaf can be identified by the author’s name or abbreviated title alongside its Arabic page number. Positioned exactly 0.5 inches (1.27 cm) from the top edge within the 1-inch manuscript margins, the page header remains visible without encroaching on the primary text block.
- Section Headings: Establish logical architecture and cognitive signposting throughout the standard parts of a research paper. A clear heading in research paper sections guides readers through the research problem, methodology, data presentation, and theoretical discussion. Beyond human readability, modern academic publishing systems use structured heading levels to build document navigation, screen-reader accessibility trees, and automated table of contents generation.
Structure
To establish a compliant heading research paper layout across your manuscript, follow this ordered structural sequence:
- Configure Document Margins and Header Distance: Set global document margins to exactly 1.0 inch (2.54 cm) on all four sides (top, bottom, left, and right). In your word processor’s page setup, set the header and footer margin distance to exactly 0.5 inches (1.27 cm) from the sheet edge.
- Select and Standardize Manuscript Typography: Apply a single accessible typeface throughout the document body and headers. Standard accepted options include 12-point Times New Roman, 11-point Calibri, 11-point Arial, or 10-point Lucida Sans Unicode. Ensure the header text uses the exact same typeface and point size as the body text.
- Determine Author Status and Target Style Manual:
- APA 7th Edition Student Papers: Insert an automated Arabic page number flush right in the page header. Do NOT include a running head title unless explicitly mandated by your instructor. Pagination begins on the research paper title page as page 1.
- APA 7th Edition Professional Manuscripts: In the header, place a shortened title of 50 characters or fewer (including spaces and punctuation) flush left in ALL UPPERCASE letters, paired with the Arabic page number flush right. Omit the legacy label “Running head:”.
- MLA 9th Edition Papers: Place your surname followed by a single space and the automated page number flush right in the header on every page (e.g.,
Morales 1), starting on page 1. In standard MLA format, no separate title page is required. - Chicago Style (Author-Date or Notes-Bibliography): Place the page number flush right in the header (or centered in the footer). When a dedicated title page is used, suppress the header and page number on the cover sheet and begin visible numbering on page 2.
- Insert Dynamic Page Number Field Codes: Never type page numbers manually on individual pages. Open the document header, position the cursor flush right, and insert an automated page number field code so that page numbers increment dynamically as text expands.
- Establish the First-Page Title Block:
- In APA 7th style, provide a dedicated title page displaying the full paper title in bold title case, author name, author affiliation format (department and university), course name/number, instructor name, and assignment due date.
- In MLA 9th style, construct a four-line heading block flush left, double-spaced, 1.0 inch from the top margin: Author Full Name, Instructor Name, Course Number, and Date (in Day Month Year format). Double-space down and center the paper title in standard plain text.
- Apply Hierarchical Section Headings: Structure body text using descending heading levels. In APA 7th, apply Level 1 (Centered, Bold, Title Case) for primary sections, Level 2 (Flush Left, Bold, Title Case) for main subsections, and Level 3 (Flush Left, Bold Italic, Title Case) for sub-subsections. Maintain consistent double-spacing throughout without inserting blank lines before or after headings.
- Validate Section Subdivisions: Never leave an orphaned single subsection. If a section contains subheadings, provide at least two subheadings at that same hierarchical tier (for instance, at least two Level 2 headings under a Level 1 heading).
| Formatting Element | APA 7th Edition (Student) | APA 7th Edition (Professional) | MLA 9th Edition | Chicago Manual (17th/18th) |
|---|---|---|---|---|

Editorial teams and manuscript reviewers frequently encounter preventable errors in the configuration of headings for research paper submissions. Avoid these eight critical pitfalls:
- Typing the Label “Running head:” in APA 7th: In the older APA 6th Edition, authors were required to type the words “Running head:” on the title page before the short title. The APA 7th Edition officially abolished this label for all manuscripts. Typing “Running head:” flags an outdated manuscript.
- Mandating Running Heads on APA Student Papers: Under APA 7th Section 2.8, student papers do not require a running head unless an instructor or department explicitly asks for one. The student page header contains only the right-aligned page number.
- Manually Typing Page Numbers: Entering literal digits (such as typing “1”, “2”, “3”) into page headers causes the typed number to repeat identically on every page of the document. Page numbers must always be inserted using the word processor’s dynamic page numbering field.
- Skipping Heading Levels: Headings in a research paper must progress logically down the hierarchy. Never jump directly from a Level 1 heading to a Level 3 heading. Each sub-tier must be introduced under its immediate parent level.
- Creating Orphaned Single Subheadings: Academic logic dictates that a section cannot be divided into only one part. If you introduce a Level 2 heading (e.g., section 2.1), you must provide at least a second Level 2 heading (section 2.2). If there is only one subordinate topic, integrate it directly under the parent heading without a subheading.
- Inserting Extra Blank Lines Around Headings: Style manuals specify uniform double-spacing throughout the entire paper. Do not add blank lines or manual paragraph returns before or after section titles.
- Confusing Heading Case with Sentence Case: APA and MLA require Title Case capitalization for headings in research paper sections (capitalizing the first word and all major words, while lowercasing conjunctions and prepositions under four letters). Avoid typing section headers in sentence case or full uppercase unless explicitly mandated by journal author guidelines.
- Inconsistent Header Typography: Word processing templates often revert default header font styles to Calibri or Arial when the body text is set to Times New Roman. Ensure that your running header matches the exact font face and point size of your manuscript body.
Checklist
Verify your manuscript against this rigorous formatting checklist before submitting your research paper for evaluation or peer review:
- [ ] Header Placement: The running header is positioned exactly 0.5 inches (1.27 cm) from the top paper edge, aligned within the 1.0-inch lateral margins.
- [ ] Dynamic Pagination: The page number is generated via an automated word processor field code and increments accurately from page 1 to the final references or works cited page.
- [ ] Style-Specific Content:
- APA 7th Student: Header contains only the page number flush right.
- APA 7th Professional: Header contains a short title in ALL CAPS (≤50 characters) flush left and the page number flush right, with no “Running head:” prefix.
- MLA 9th: Header contains author surname and page number separated by a space (e.g.,
Author 1) flush right on all pages. - Chicago: Header contains the page number flush right or centered in the footer; cover sheet pagination is suppressed.
- [ ] Typography Harmony: Header font family and size match body text exactly (e.g., 12 pt Times New Roman throughout).
- [ ] Heading Hierarchy: All headings of a research paper adhere strictly to the target style guide’s level definitions (bold, italic, centering, and indentation).
- [ ] No Orphan Subsections: Every divided section contains at least two subordinate headings at that level.
- [ ] Uniform Line Spacing: The entire document is double-spaced, with zero extra blank carriage returns surrounding section titles.
- [ ] Semantic Style Application: In-text headings are formatted using native word processor styles (Heading 1, Heading 2, Heading 3) to ensure screen-reader navigation and clean table of contents export.
Discipline differences
The conventions governing headings of research paper manuscripts vary systematically across academic disciplines and indexing bodies:
- Social Sciences and Behavioral Research (APA Style): APA manuscripts prioritize strict 5-level section headings to maintain rigorous reporting across quantitative and qualitative studies. Clinical, psychological, and educational empirical articles adhere strictly to standard IMRaD section headers (Introduction, Method, Results, Discussion), utilizing run-in headings (Levels 4 and 5) to demarcate granular measurement tools, participant demographics, and statistical parameters.
- Humanities and Literary Studies (MLA Style): MLA manuscripts prioritize prose continuity over fragmented subheadings. In short argumentative essays, section headings are generally discouraged; transitions are achieved through topic sentences. In extended monographs, master’s theses, or dissertations, MLA allows unnumbered, flush-left headings formatted in descending typographical weight.
- History and Fine Arts (Chicago / Turabian Style): Chicago allows authors flexibility between dedicated cover sheets and first-page heading blocks. When subheadings are employed, Chicago permits either centered bold or flush-left italic formatting, provided the typographic scheme remains uniform across all chapters and appendices.
- Engineering and Computer Science (IEEE Style): Unlike humanities formats, IEEE manuscripts utilize an explicit alphanumeric decimal hierarchy. Primary headings are designated with Roman numerals centered in small caps (e.g.,
I. INTRODUCTION), secondary headings use uppercase letters flush left in italics (e.g.,A. Experimental Framework), tertiary headings use numbered run-in clauses (e.g.,1) Sensor Calibration:), and quaternary headings use lowercase lettered run-in clauses.
FAQ
What is the difference between a header and a heading in a research paper?
A header (or page header) is the running text located in the top 0.5-inch margin of each page, displaying identifying details such as the running head, author last name, and page number. A heading is an in-text section title (such as Introduction, Methods, or Results) that organizes the narrative structure and content hierarchy of the manuscript body.
Does APA 7th edition require a running head for student papers?
No. Under APA 7th Edition rules (Section 2.8), student research papers do not require a running head unless an instructor, department, or academic institution explicitly requests one. The page header on student papers consists solely of the right-aligned page number.
What should be in an MLA 9th edition header?
An MLA 9th Edition page header consists of the author’s last name followed by a single space and the current Arabic page number (for example, Smith 1). It is placed in the upper right corner of every page, exactly 0.5 inches from the top edge, right-aligned with the 1.0-inch margin.
How many heading levels does APA style support?
APA 7th Edition defines five distinct heading levels. Levels 1 through 3 are standalone lines with text beginning on the following line (Level 1 is centered and bold; Level 2 is flush left and bold; Level 3 is flush left and bold italic). Levels 4 and 5 are indented run-in headings ending with a period, where body text begins immediately on the same line (Level 4 is bold; Level 5 is bold italic).
Should research paper headings have extra blank lines before or after them?
No. Standard academic style guides (including APA, MLA, and Chicago) mandate uniform double-spacing throughout the entire manuscript. You should not add extra blank carriage returns or increase paragraph point spacing before or after section headings.
How do I make the first page header different in Microsoft Word or Google Docs?
In Microsoft Word, double-click the header area, navigate to the Header & Footer ribbon tab, and check the box labeled “Different First Page”. In Google Docs, click into the header and select the checkbox labeled “Different first page”. This unlinks the first-page header, allowing you to format a unique title page header in Chicago style or suppress the running head on a student paper cover sheet.
