Headings and subheadings
Use these guidelines for headings and subheadings to help make your page readable and accessible.
Why headings are important
Readers can be put off by large areas of text.
Headings provide a clear structure for how information is organised on a page, and highlight the key messages. People use headings to understand how different areas of text are related.
The Readability Guidelines include detailed guidelines on the following topics:
- Use specific, meaningful headings.
- Front-load headings.
- Structure your page with headings.
- Use sentence case for headings and subheadings.
- Label your headings.

Do not pick a heading format you think looks best. Keep to the HTML hierarchy. For example, do not use h3 unless it’s under h2.
