The four cases and when to use them
- UPPERCASE — every letter capital; use sparingly for emphasis or acronyms.
- lowercase — no capitals; common for tags, usernames, code and casual style.
- Title Case — Major Words Capitalized; used for headlines and titles.
- Sentence case — only the first letter capital; natural for body text and most headings today.
A note on Title Case rules
Traditional Title Case capitalizes the first and last words and all major words, but leaves short conjunctions, articles and prepositions (a, an, the, and, but, of, to) lowercase unless they start the title. Different style guides vary slightly, so pick one and be consistent.
Many modern brands and publications now prefer Sentence case for headings because it feels friendlier and is easier to read. When in doubt, match the style already used around your text.
