What Are Headings?

Headings are the most essential aspect of creating accessible content, and are applied to sections of content to organize information in a logical order of importance.

Headings add structure to content by grouping related information into levels. They create a predictable pattern that allows all users to easily navigate content.

How Do Headings Work?

Headings group related information into levels.

Heading 1 Title

Heading 2 Major Topic

Heading 3 Minor Topic

Heading 4 Subtopic

Heading 5

Heading 6

Paragraph (body text)

Headings are based on the principle of information hierarchy. 

We use information hierarchy every day to organize items and ideas, even when doing the laundry:

Heading 1 Laundry

Heading 2 Light Items

           Heading 3 Light Towels

                      Heading 4 Bath towels

                      Heading 4 Washcloths

           Heading 3 Light Clothing

                      Heading 4 Shirts

                      Heading 4 Pants

                      Heading 4 Undergarments

       Heading 2 Dark Items

           Heading 3 Dark Towels

                        Heading 4 Bath towels

                        Heading 4 Washcloths

           Heading 3 Dark Clothing

                        Heading 4 Shirts

                        Heading 4 Pants

                        Heading 4 Undergarments

Headings exactly work like an outline structure.  

An outline structure easily transforms to headings. Roman numeral I corresponds to Heading 1. The uppercase A, B, C level corresponds to Heading 2. The 1, 2, 3 level corresponds to Heading 3. The lowercase a, b, c level corresponds to Heading 4. Anything that is not a heading (an overall topic) and is text supporting that topic is P, paragraph or body text.

How Do Headings Organize a Document?

The usefulness of a document can be quickly improved using headings.  Instead of an intimidating “wall of text” or “word salad”, content is organized into a navigable presentation that can be easily skimmed.

Headings structure content.

Headings make content useful.

Simply put, headings organize “word salad” into “word bento” and make content useful.

What Are Best Practices for Headings?

Minimum Requirements

At a minimum, all documents need an H1 and P.

Single-topic documents – for example, a flyer designed to market an event – will likely only have an H1 and all other text marked as paragraphs.

Documents with multiple related topics should have a logical heading structure with H1, H2s, and other heading levels as appropriate.

Anything that is not a heading is simply P, Paragraph or Body text.

Headings are NOT:

  • Used to increase the size of the text
  • Used to change how the text looks
  • Optional (All content needs an H1 and P tags.)

Headings MUST:

  • Be used in order.

Do not skip between levels, i.e. set H2 and then go to H4.

INCORRECT:
        
Types of Analog Media Heading 2

Magnetic Tape Heading 4

CORRECT:

Types of Analog Media Heading 2

Magnetic Tape Heading 3

8-Track Heading 4

Cassette Tape Heading 4

Each higher-level heading should have a pair of lower-level headings.  If the section doesn’t warrant a second heading, rewrite it.

INCORRECT: 

Hotdog Heading 1

Bratwurst Heading 2

CORRECT:

Types of Hotdogs Heading 1

Chili Cheese Dog Heading 2

Bratwurst Heading 2

Nathan’s Famous Heading 2

A repeated pattern allows readers to easily anticipate sections.

INCORRECT:


Importance of Accessible Communication Heading 2


What are the Benefits of Accessible Communication? Heading 2


Prioritize Users’ Needs with Accessible Communication Heading 2

CORRECT:


Understand the Importance of Accessible Communication Heading 2

Discover the Benefits of Accessible Communication Heading 2

Prioritize Users’ Needs with Accessible Communication Heading 2

  • Function as independent labels.  

Sentences should make sense on their own and not rely on the heading.

INCORRECT: 

       
Heading 3: Understanding the Tuition Reimbursement Policy


Paragraph: This allows employees to receive reimbursement for classes.

CORRECT:

          
Heading 3: Understanding the Tuition Reimbursement Policy


Paragraph: The Tuition Reimbursement Policy allows employees to receive reimbursement for classes.

What Are the Benefits of Headings?

Screen Reader Users

  • Headings create pattern access technologies follow to read documents to users.
  • Headings allow users to jump between sections and hear the information they want.  (This creates an experience equivalent to a visible table of contents or bookmarks panel.)
  • Users must listen to the screen reader voice the entire document if headings are not used.

All Users

All users benefit from content broken into navigable sections.

When used properly, Headings will generate:

  • An interactive table of contents in Word or InDesign
  • A clickable document map in Word
  • A clickable bookmarks panel in Adobe PDF

Content Authors

Headings benefit content authors by ensuring that the content:

  • Can be accessed, used, and understood by all users
  • Looks professional, clean, and useful
  • Is well-organized with obvious sections that are easy to skim
  • Guides users to what they need to know or do
  • Save time and effort by reducing the need for follow-up communication
