A large bold paragraph is not necessarily a heading in Google Docs. Apply actual heading styles so the document has a useful hierarchy for navigation, a table of contents, and readers using assistive technology.
Apply a semantic heading style
- Select the heading text or click inside its paragraph.
- Open the style selector that normally shows Normal text, or choose Format > Paragraph styles.
- Choose the appropriate Heading level.
- Check its appearance and position in the document outline.
Use Heading 1 for a major division and subordinate levels for sections within it. Choose levels according to the content’s structure rather than because one level happens to have the font size you like.
Keep structure and appearance separate
You can customize a heading style’s font and size while retaining its structural role. This is preferable to using bold Normal text for every section title. Consistent styles also make later appearance changes easier to apply.
Title, Subtitle, and Heading styles serve different purposes. Google’s outline guidance notes that subtitles do not appear in the outline. If a navigation entry is missing, check its actual paragraph style before repeatedly increasing its font size.
Review the resulting hierarchy
Open the outline and read its headings in order. They should describe the document without requiring the body paragraphs. Replace vague labels with meaningful section names where appropriate, and check that subordinate topics sit beneath the correct parent.
Inspect the exported document when it is the final deliverable. A useful heading hierarchy improves the source, but the destination format should still be checked for navigation and accessibility. Avoid empty heading paragraphs used only to create extra vertical space.
