An appendix in APA 7th edition provides supplementary material that enriches an academic paper without disrupting the main text flow. Determining when to label appendices with letters, how to format appendix headings, and how to cite them in-text frequently causes confusing layout errors for student writers.

This guide explains how to format single and multiple appendices, integrate supplementary tables and figures, and configure page numbering in Microsoft Word.

When to Include an Appendix in APA Style

Structuring supplementary material requires adhering to precise APA 7th edition formatting rules. Configuring an appendix in APA 7th edition requires adhering to specific labeling conventions, distinct heading hierarchies, and rigorous table formatting standards.

Understanding APA 7th Edition Appendix Rules

Before you start typing, know the core logic: an appendix is supplementary material that supports your paper but isn’t essential to the main argument. Think raw data, questionnaires, or large tables. APA 7 has strict rules about how to label, format, and place them. Getting this wrong can cost you points on an assignment or a rejection from a journal. Let’s break it down.

First, every appendix must be mentioned at least once in your main text. If you never refer to it, don’t include it. ” If you have multiple, use letters: “Appendix A,” “Appendix B,” and so on.

Third, each appendix starts on a new page. Finally, the appendix section comes after the reference list, not before. This is a common mistake that can throw off your entire document’s flow.

Setting Up Your Appendix Page

Step 1: Create a New Page After References

Insert a page break after your reference list. In Microsoft Word, go to the Insert tab and click “Page Break.” In Google Docs, use Ctrl+Enter (Windows) or Cmd+Enter (Mac). This ensures your appendix starts on a fresh page.

Step 2: Add the Appendix Label

Center the word “Appendix” (if you have one) or “Appendix A,” “Appendix B,” etc. (if multiple). Use bold, title case, and the same font size as your paper’s headings — typically 12 pt Times New Roman. Do not italicize or underline. Double-space before and after the label.

Step 3: Write a Descriptive Title

On the next line, centered and bold, add a title that describes the content. For example: “Survey Questions Used in Study.” This title should be specific and informative. It’s not optional — APA 7 requires it.

Step 4: Format the Body Content

Start your content on a new line, left-aligned, double-spaced. Use the same font and margins as the rest of your paper (1-inch margins, 12 pt Times New Roman).

, and give them a brief title. For more on figure captions, see How to Format a Figure Caption in APA, MLA, and Chicago.

Step 5: Number Pages Continuously

Your appendix pages continue the page numbering from the main body. If your paper ends on page 12, your appendix starts on page 13. Don’t restart numbering. Also, include a running head on every page — yes, even the appendix. Learn how to set that up without formatting errors in How to Format a Running Head in APA 7th Edition (Without Losing Your Mind).

Pro Tips for Flawless Appendix Formatting

Tip 1: Use Heading Styles for Consistency. Apply APA 7th heading levels within your appendix if it contains subsections. For instance, “Appendix A” functions as a Level 1 heading, while “A.1 Methodology” is formatted as Level 2. Maintaining standardized heading styles ensures clear outline navigation and automated table of contents indexing.

Tip 2: Automate Your Table of Contents. If your appendix has multiple tables or sections, update your Table of Contents to include them. Simply apply heading styles to your appendix labels and titles, then refresh the TOC. For a full walkthrough, see How to Update and Sync a Table of Contents in Microsoft Word.

Tip 3: Avoid Common Mistakes. The biggest errors are placing the appendix before references, forgetting to mention it in the text, and using incorrect labeling. If you want to catch every mistake, read 5 Common APA Formatting Mistakes (And How to Fix Them).

Tip 4: Convert Citations if Needed. If you’re working with sources in multiple styles, you might need to convert MLA to APA for consistency inside your appendix. Use How to Convert a Citation from MLA to APA (Without Starting Over) for a smooth process.
