Sentence Case vs Title Case: When to Use Each
The two most common capitalization styles for headings and titles — compared side by side, with style guide rules, real examples, and a quick-reference cheat sheet.
What is the Difference?
Sentence case capitalizes only the first word of a heading or title plus any proper nouns — just like you would capitalize a normal English sentence. Everything else is lowercase.
Title case capitalizes the first letter of most words in a heading — specifically major words like nouns, verbs, adjectives, and adverbs — while leaving minor words (articles, short prepositions, conjunctions) in lowercase.
| Style | Example |
|---|---|
| Sentence case | How to write better blog posts in 2026 |
| Title case | How to Write Better Blog Posts in 2026 |
| Sentence case | The benefits of exercise for mental health |
| Title case | The Benefits of Exercise for Mental Health |
| Sentence case | A beginner's guide to JavaScript |
| Title case | A Beginner's Guide to JavaScript |
Key Differences at a Glance
| Feature | Sentence Case | Title Case |
|---|---|---|
| Words capitalized | First word + proper nouns | Most major words |
| Reading difficulty | Lower (resembles normal text) | Slightly higher |
| Common in | Web content, UI, UK publications | Books, US journalism, academia |
| Style guides | Google, Microsoft, Guardian | APA, MLA, Chicago, AP |
| Consistency required | Know your proper nouns | Know the word-type rules |
Which Style Guides Use Sentence Case?
Sentence case is increasingly favored in digital and tech contexts:
- Google Material Design — recommends sentence case for all UI text
- Microsoft Writing Style Guide — prefers sentence case for most headings
- The Guardian (UK) — uses sentence case for article headlines
- BBC — sentence case in headlines
- Shopify Polaris — sentence case for UI components and headings
- IBM Carbon Design — sentence case throughout
Which Style Guides Use Title Case?
Title case remains dominant in traditional publishing and American journalism:
- APA Style — title case for paper titles and journal names
- MLA Style — title case for work titles
- Chicago Manual of Style — title case in book and article titles
- AP Stylebook — headline style (title case) for news headlines
- The New York Times — title case for article headlines
- Most US news outlets — title case for headlines
Sentence Case vs Title Case for Blog Posts
For blog post titles, both styles are widely used. American content typically follows title case (HubSpot, Forbes, Content Marketing Institute), while many tech blogs and international publications lean toward sentence case (Stripe, Linear, Notion documentation).
The most important rule: pick one and apply it consistently across your entire site. Mixing styles looks inconsistent and unprofessional.
Sentence Case vs Title Case for H2 and H3 Subheadings
Even when a publication uses title case for its H1 article titles, subheadings (H2, H3) often use sentence case for readability. This is especially common in long-form content and technical documentation where readers scan headings quickly. Google's own documentation uses title case for page titles but sentence case for section headings.
Which is Better for SEO?
Google has no stated preference between sentence case and title case for page titles or headings. Both can rank equally well. However, Google may rewrite your title tag in SERPs to better match user intent — sometimes changing capitalization to match how users phrase their queries. Focus on clarity and keyword relevance rather than capitalization style for SEO purposes.
