A table of contents in Word looks straightforward to create — but most business documents have one that was either typed manually, generated once and never updated, or built on headings that were formatted by hand rather than through Word Styles. The result is a TOC that shows the wrong page numbers, misses sections, or fails to update when the document is edited. This guide shows you how to create a table of contents in Word that actually works — automated, accurate and always in sync with your document. If you need it done for you, our word document formatting service handles this as standard from £1.95 per page.

How Word’s Table of Contents Actually Works
Word’s automated table of contents works by scanning your document for text that has a Heading Style applied — Heading 1, Heading 2 or Heading 3 — and listing those headings with their page numbers. It does not scan for text that looks like a heading. It only finds text that has been structurally identified as a heading through the Styles system.
This is the single most important thing to understand about Word tables of contents. A heading that is bold and large but formatted manually will not appear in the TOC. A heading that uses Heading 1 Style will always appear. The visual appearance of a heading and its structural identity are completely independent in Word.
This is why the most common TOC problem — missing headings — almost always means the headings have been formatted manually rather than via the Styles panel. Our guide to using Styles in Microsoft Word explains the full Styles system, and our guide to fixing heading styles in Word covers how to correct them.
How to Create a Table of Contents in Word — Step by Step
How Many Heading Levels to Include
By default Word shows three heading levels in the TOC (Heading 1, 2 and 3). For most business documents, two levels is the right choice — enough to show structure without overwhelming the reader.
| Document type | Recommended TOC levels | Reason |
|---|---|---|
| Business report | 2 levels | Shows sections and sub-sections without excessive detail |
| Client proposal | 2 levels | Keeps the TOC concise and navigable |
| Board pack | 2–3 levels | Directors need to navigate to specific sub-sections quickly |
| Legal document | 3 levels | Clause hierarchy requires full navigation depth |
| Policy document | 2 levels | Employees scan policy documents — keep navigation simple |
To change the number of levels shown: References → Table of Contents → Custom Table of Contents → change “Show levels” to 2 or 3.
How to Customise the TOC Appearance
The default Word TOC appearance may not match your document’s brand or style guide. To customise it without breaking the automated functionality:
Right-click the TOC → Edit Field → Table of Contents → Modify to adjust the TOC Style for each heading level
Modify TOC 1, TOC 2 and TOC 3 Styles in the Styles panel to change font, size, indentation and spacing
Set tab leaders (the dots between entry and page number) via Format → Tabs within the TOC Style settings
Apply direct formatting (bold, font change, colour) to TOC entries — it is overwritten every time you update the TOC
How and When to Update the TOC
Word does not update the TOC automatically. You must refresh it manually before every finalised version of the document.
| Situation | Update type |
|---|---|
| Content added or removed — headings may have moved | Update Entire Table |
| Only text within sections changed — headings unchanged | Update Page Numbers Only |
| Headings added, removed or renamed | Update Entire Table |
| Before saving final version for distribution | Always Update Entire Table |

Frequently Asked Questions
How do I create a table of contents in Word?
Apply Heading Styles (Heading 1, Heading 2, Heading 3) to all headings using the Styles panel. Place your cursor where the TOC should appear. Go to References → Table of Contents → select an automatic style. Right-click → Update Field → Update Entire Table to verify it is correct. See our step-by-step guide above for full detail.
Why does my Word table of contents not update automatically?
Word does not update the TOC automatically — you must right-click and select Update Field each time. If the TOC does not update correctly, check all headings are using proper Heading Styles. Our guide to fixing heading styles in Word covers how to check and correct them.
How many heading levels should my TOC show?
Two levels for most business reports and proposals. Three levels for longer documents such as board packs and legal documents where readers need to navigate to specific sub-sections. Showing more than three levels typically makes the TOC harder to use rather than more helpful.
Can I customise how the table of contents looks?
Yes — modify the TOC 1, TOC 2 and TOC 3 Styles in the Styles panel to change font, indentation and spacing. Never apply direct formatting to TOC entries as it is overwritten on the next update. Always modify the Style definition instead.
Can you create a table of contents in my document professionally?
Yes. Our word document formatting service creates and configures automated tables of contents as standard. We apply correct Heading Styles, insert the TOC and verify it updates correctly — along with fixing any other formatting issues in the document. Contact us with any questions before submitting.
