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.
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 |

| 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 |
Sentence case is increasingly favored in digital and tech contexts:
Title case remains dominant in traditional publishing and American journalism:
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.
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.
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.

Sentence case capitalizes only the first word and proper nouns. Title case capitalizes most words — nouns, verbs, adjectives, and adverbs — while leaving articles, conjunctions, and short prepositions lowercase.
Both work. US content typically uses title case. Modern tech brands and UK publications tend to use sentence case. Pick one and stay consistent throughout your site.
Google has no stated preference. Both rank equally. Google may rewrite your title tag in search results regardless of case. Focus on clarity and keywords, not capitalization.
