If you’ve ever struggled with long Word documents, making them easy to navigate can save you—and anyone else who reads them—a lot of time. One of the best ways to do this is by using a table of contents in Word. With a few clicks, you can generate a clickable, automatic table of contents that updates itself as you edit your document. Here’s a step-by-step guide on how to create a table of contents in Word that will stay dynamic, even after exporting to PDF.

Whether you’re working on a research paper, a report, or any other large document, this makes things a lot easier for you and your reader.

Step 1: Start with Proper Formatting

The key to adding a table of contents in Word is to format your document properly from the get-go. Word uses predefined heading styles (Heading 1, Heading 2, Heading 3, etc.) to recognize section titles that belong in the table of contents. Without using these headings, your table of contents won’t populate correctly.

Let’s break this down:

  • Heading 1: Use for main sections or chapters of your document.
  • Heading 2: These should be sub-sections under Heading 1.
  • Heading 3 and beyond: You can take this as deep as you want—Word supports Heading 4, 5, and even more if needed. However, as you add more headings, each new one appears slightly smaller and more indented than the last.

For example:

  • Heading 1 might be titled “Video, Audio, Gaming, and Software”.
  • Under “Audio”, Heading 2 could be titled “Recording” or “Live Streaming”.
  • You could use Heading 3 for even more detailed sections like “Selecting a Microphone” or “Audio Settings for Streaming”.

Bonus Tip: Exclude the Title

You likely don’t want your document’s main title (shown on the cover page, for instance) to appear in the table of contents. To avoid this, enable the Title style, which won’t be included when the table of contents generates.

Step 2: Inserting Your Table of Contents

Once your document is formatted with appropriate headings, inserting the table of contents is a breeze. Here’s how:

  1. Go to the References tab in Word.
  2. Look for the Table of Contents dropdown.
  3. Select an Automatic Table. You’ll see two built-in options, but either one works the same way for automatic updates.

After selecting one, Word will automatically insert a clickable table of contents. You’ll see a full list of your headings, indented based on their hierarchy.

When someone reading your document clicks on any of the sections in the table of contents, it will jump directly to that part of the document. Simply hold down “Control” (Ctrl) and click to navigate to the selected section.

Step 3: Editing the Table of Contents

Once the table is in place, you have some freedom to modify it. Word allows you to tweak the look of your table of contents without breaking its automatic features:

  • Change the font, size, style, and color: Select the table of contents and apply formatting changes as you would with normal text. However, I usually recommend sticking with the default settings for readability and simplicity.
  • Add highlights or bold text: This can help make key sections of your document stand out. For example, if certain sections are more important, consider using bold or a different color for their listing.

If you’re sharing the file as a PDF, there’s good news: Word lets you export the clickable table of contents to a PDF without losing any of its functionality. This ensures that anyone using your PDF will be able to navigate easily by clicking through the sections.

Here’s how to export:

  1. Go to File and select Export.
  2. Choose Create PDF/XPS Document.
  3. Save the file in your desired location.

When opened, the clickable links from your table of contents will remain active in the PDF, allowing your readers to move easily from section to section.

Step 5: Updating the Table of Contents

As you make changes to your document—adding sections, deleting paragraphs, or changing titles—you’ll need to update the table of contents. Fortunately, Word makes this simple:

  1. Click anywhere inside the table of contents.
  2. A header will appear at the top saying Update Table.
  3. Choose the Update Page Numbers Only option if no structure has changed, or choose Update Entire Table if you’ve changed section titles or added new sections.

This will refresh your table of contents to reflect your latest edits.
