Question details

The user needs to resolve an issue where specific headings do not appear in the generated Word Table of Contents.

Product: Word
Device & OS: not provided
Scenario: Generating or updating a Table of Contents in a text document.
Observed behavior: Certain headings are missing from the Table of Contents because their styles are not applied to the entire paragraph or the custom style outline level is configured incorrectly.

Before you start

Before updating your Table of Contents, locate the exact headings in your document text that are failing to appear so you can check their applied styles.

Solution 1Recommended

Apply Built-in Heading Styles to the Entire Paragraph

Ensure that Word's standard heading styles are applied to the complete paragraph so they are automatically captured by the Table of Contents.

Word relies on built-in heading styles (Heading 1, Heading 2, etc.) to structure the Table of Contents. If the style is only applied to a portion of the text rather than the whole paragraph, Word might ignore it.

Select the heading text

Highlight the entire line or paragraph of the heading that is missing from your Table of Contents.

Apply a built-in heading style

Navigate to the Home tab on the ribbon. In the Styles group, click on Heading 1, Heading 2, or Heading 3.

Update the Table of Contents

Scroll back to your Table of Contents, right-click anywhere inside it, and select 'Update Field'. Choose 'Update entire table' and click OK.

Tip: Using built-in styles is usually the most reliable method as Word automatically associates them with outline levels 1, 2, and 3.

Solution 2

Adjust Outline Levels for Custom Styles

If you prefer using custom styles for your document, you must manually set their outline level to ensure Word recognizes them as headings.

Frequently Asked Questions

Why did my Table of Contents update with the wrong page numbers?

This usually happens when document edits shift the text onto different pages. Right-click anywhere in the Table of Contents, choose 'Update Field', and select 'Update page numbers only' or 'Update entire table' to refresh the pagination.

Can I include unstyled text in my Table of Contents?

Yes, you can manually mark standard text for inclusion without changing its visual style. Highlight the text, go to the References tab, click 'Add Text', and select the appropriate outline level (Level 1, 2, or 3).

How do I change the font and formatting of the Table of Contents itself?

Go to the References tab, click 'Table of Contents', and select 'Custom Table of Contents'. Click 'Modify' to change the specific TOC styles (TOC 1, TOC 2, etc.) to match your desired font and spacing.

Why is a whole paragraph of normal text showing up in my Table of Contents?

This occurs when a Heading style or a specific Outline level was accidentally applied to a full paragraph instead of just a single line. Highlight the offending paragraph in your document and apply the 'Normal' style to remove it from the TOC hierarchy.
