Headings in Word Documents

Headings create the structural backbone of your document. Screen reader users rely on headings to navigate and understand document organization, much like sighted users scan headings visually.

What This Means

Using Word's built-in heading styles (Heading 1, Heading 2, etc.) creates a navigable document structure. Screen readers can list all headings, allowing users to jump directly to sections of interest.

Why It Matters

• Screen reader users navigate by headings - it's their primary way to scan documents
• 73% of screen reader users list headings as their top navigation method
• Proper headings create an automatic table of contents
• Documents without headings force users to read linearly from start to finish

Common Violations

DOCX-03-001: Document Does Not Use Heading Styles {#DOCX-03-001}

What's Wrong: The document has no heading styles applied. All text uses Normal or Body text style, even for titles and section headers.

Impact: Serious - Screen reader users cannot navigate the document structure.

How to Identify:

• Open the Navigation Pane (View > check Navigation Pane)
• If no headings appear in the pane, the document lacks heading structure
• Check the Styles pane to see what styles are applied

How to Fix:

1. Select the text that serves as a heading
2. Go to Home tab
3. In the Styles group, click the appropriate heading level:
   • Heading 1 - Document title or main sections
   • Heading 2 - Subsections under Heading 1
   • Heading 3 - Sub-subsections under Heading 2

Heading Hierarchy:

Heading 1: Document Title
  Heading 2: Chapter or Major Section
    Heading 3: Subsection
      Heading 4: Sub-subsection

DOCX-03-002: Heading Levels Are Skipped {#DOCX-03-002}

What's Wrong: The document jumps from one heading level to another, skipping levels in between (e.g., Heading 1 directly to Heading 3, skipping Heading 2).

Impact: Moderate - Creates a confusing document structure that's harder to navigate.

How to Identify:

• Open the Navigation Pane
• Check if any heading levels are missing in the hierarchy
• Look for Heading 3 appearing directly under Heading 1

How to Fix:

1. Review your document's heading structure in the Navigation Pane
2. Adjust skipped headings to the correct level:
   • Select the incorrectly leveled heading
   • Apply the correct heading style from the Home tab

Example of Skipped Headings (Wrong):

Heading 1: Introduction
Heading 3: Background      <- WRONG: Should be Heading 2
Heading 3: Purpose         <- WRONG: Should be Heading 2

Corrected:

Heading 1: Introduction
  Heading 2: Background
  Heading 2: Purpose

DOCX-03-003: Heading Style Used for Visual Formatting Only {#DOCX-03-003}

What's Wrong: Heading styles are applied to text that isn't actually a heading, just to make it bold or larger. This pollutes the document structure with fake sections.

Impact: Moderate - Creates false navigation points that confuse screen reader users.

How to Identify:

• Check the Navigation Pane for entries that aren't actual headings
• Look for heading styles applied to:
  • Pull quotes or callout text
  • Emphasized paragraphs
  • Text that should be bold but isn't a section header

How to Fix:

1. Select the incorrectly styled text
2. Apply Normal or Body Text style instead
3. To make text bold or larger without using headings:
   • Select the text
   • Use Bold (Ctrl+B) for emphasis
   • Change font size directly in the Font group
   • Create a custom style for frequently used formatting

Creating a Custom Style for Bold Text:

1. Format a paragraph the way you want (bold, larger, etc.)
2. Select the formatted text
3. Right-click in the Styles gallery
4. Choose Create a Style
5. Name it (e.g., "Bold Emphasis")
6. Use this style instead of heading styles for non-heading text

Using Microsoft's Accessibility Checker

Word's Accessibility Checker can identify heading issues:

1. Go to Review > Check Accessibility
2. Look for warnings about headings
3. Common warnings include:
   • "Skipped heading level"
   • "Heading length is too long"
   • "No heading styles used"

The Navigation Pane: Your Best Friend

The Navigation Pane shows your document's heading structure at a glance:

1. Go to View tab
2. Check Navigation Pane
3. The Headings tab shows all headings in order
4. Click any heading to jump to that section
5. Drag headings to reorganize sections

A well-structured document shows a clear, logical hierarchy in the Navigation Pane.

Best Practices

Do:

• Start with Heading 1 for the document title or main topic
• Use headings sequentially (1, 2, 3) without skipping
• Keep heading text concise and descriptive
• Use headings consistently throughout the document
• Review the Navigation Pane before finalizing

Don't:

• Use headings just for visual formatting
• Skip heading levels (Heading 1 to Heading 3)
• Make headings too long (keep under 10 words when possible)
• Apply heading styles to non-heading content
• Use bold formatting instead of heading styles for section titles
