Capital letters are typically used at the start of a sentence and for proper nouns.
Headings
Headings always use sentence-case (not title-case), excluding H1 page headings which are all-caps.
Sentence-case
Always use sentence-case for:
Navigation menus (unless linking a branded product).
CTA buttons and hyperlinks (no full stops but fine to use question marks)
Validation or error messages
Form fields
Numerical amounts
Capitalisation
Always use capitalisation for:
Branded names (but not generic names of products or services)
Page meta titles (for SEO)
Guides
Holidays - see People & Diversity for more.
Days and months
Geographical names
Languages
Government departments
Job titles (official titles only)
Awards
Lower-case
Always use lower-case for:
Seasons
Online terms
Capitalisation rules do not apply when a formal name is written in lower or upper case.
States and territories
States and territories have each word capitalised.
Countries
Take note of the way we refer to certain countries.
- China – use China, not PRC
- United Kingdom - use UK or United Kingdom, not England or Great Britain
- United States - use US or United States, not USA, America or United States of America.
Note: For H1 headings, US reads as ‘us’, so use U.S.
