To create a table of contents in Word, you first apply heading styles to your document (Heading 1, Heading 2, etc.), then insert an automatic Table of Contents from the References tab and update it as your document changes.

Quick Scoop

If you’re writing a report, thesis, or long assignment in 2026, using Word’s automatic table of contents is still the fastest, most reliable way to keep everything organized and “clickable.”

Step 1: Prepare Your Headings

Word builds the table of contents from your headings, not from font size or bold text alone.

  1. Select your main chapter or section title text.
  2. Go to the Home tab.
  3. In the Styles group, click Heading 1 for main sections.
  1. For subheadings under that section, select the text and choose Heading 2 (and Heading 3 for deeper levels if needed).
  1. Repeat throughout your document so every section you want in the TOC has a heading style applied.

You can customize how these headings look (font, size, color), and the TOC will still recognize them as long as they remain Heading 1/2/3 styles.

Step 2: Insert an Automatic Table of Contents

Once headings are in place, you can generate the table of contents in a few clicks.

  1. Place your cursor where you want the TOC (usually after the title page).
  2. If you want it on its own page, insert a page break (Ctrl+Enter) first.
  1. Go to the References tab on the ribbon.
  2. Click Table of Contents (or Insert Table of Contents , depending on your version).
  1. Choose one of the Automatic table styles (e.g., Automatic Table 1 or 2).
  1. Word instantly creates a TOC with page numbers and dotted leaders between headings and page numbers.

You can Ctrl+Click (or Command+Click on Mac) any entry to jump directly to that section, which is especially useful for long documents.

Step 3: Update the Table of Contents

Any time you add, delete, or move sections, you should refresh the TOC so page numbers and titles stay accurate.

  1. Click anywhere in the table of contents.
  2. Click Update Table (or right‑click and choose Update Field).
  1. Choose:
    • Update page numbers only if the headings are the same but pages changed, or
    • Update entire table if you added, removed, or renamed headings.

Doing this takes seconds and prevents the classic mistake of stale page numbers in a “final” report.

Step 4: Customize the TOC (Optional)

If you want more control—like including deeper levels or changing dot leaders—use a custom table of contents.

  1. Go to References > Table of Contents > Custom Table of Contents… (or Insert Table of Contents).
  1. In the dialog box, you can:
    • Change Tab leader (dots, dashes, or none).
 * Set **Show levels** (e.g., 2 for Heading 1 + 2, 3 to include Heading 3, etc.).

 * Toggle **Show page numbers** on or off.
  1. Click OK to apply.

To change the styling (font, spacing) of TOC lines themselves, modify styles like TOC 1, TOC 2, etc., in the Styles pane.

Step 5: Manual Entries (Less Common)

If a section isn’t using heading styles, you can still force it into the TOC using manual TOC entries.

  • Use the shortcut Alt+Shift+O (letter O) to open the Table of Contents Entry box.
  • Type or edit the text for how it should appear in the TOC, and choose a Level (1 for main, 2 for sub, etc.).
  • Later, generate or update your TOC and those entries will appear alongside the automatic headings.

This is handy when, for example, you want a front-matter line like “Acknowledgements” to show in the TOC, but you don’t want to restyle it as a heading.

Mini Forum‑Style Notes & Tips

“Automatic tables of contents are a lifesaver for theses and dissertations—you just update once before submission instead of hunting page numbers manually.”

  • For long academic documents, leveraging Heading 1–3 and the Navigation Pane gives you a clickable outline and a clean TOC at the same time.
  • If your TOC is empty, it’s almost always because headings are formatted with manual bold/size instead of heading styles.
  • You can remove a TOC by clicking it and choosing Remove Table of Contents (or deleting the field), then insert a new one if you change your layout.

Simple HTML Table Example (Conceptual)

Here’s a tiny HTML-style table showing the basic mapping between heading styles and TOC levels:

Heading style in document TOC level (default) Shown in automatic TOC?
Heading 1 Level 1 Yes
Heading 2 Level 2 Yes
Heading 3 Level 3 Yes
By default, Word includes Heading 1–3 in the TOC, and you can change levels or add more in the Custom Table of Contents options.

Quick TL;DR

  • Use Heading styles for all titles and subtitles.
  • Go to References > Table of Contents and choose an automatic style.
  • Update Table whenever you edit headings or page numbers.
  • Use Custom Table of Contents for advanced control over levels, leaders, and layout.
