If you’ve ever stared at a draft headline and thought, “Why does this look… off?”, it’s often not the wording. It’s the capitalization rules, which affect how readers perceive headlines.
For title case vs sentence case blog titles, the best choice usually comes down to one thing: what feels most readable and consistent for your readers. Pick a default, apply it everywhere, then test changes when a series (or a channel) calls for a different tone.
Title case vs sentence case: what they mean in plain English
Title case, standard for formal writing, capitalizes most major words, so the title looks like a headline. Sentence case capitalizes only the first word (plus proper nouns), so it reads more like a normal sentence.
If you want a deeper refresher on the “down style” approach, see Sentence case explained. If you’d like a quick definition from a mainstream writing tool, Grammarly’s breakdown of title case vs. sentence case is also helpful.
In title case, major words like nouns, verbs, adjectives, adverbs, and pronouns are capitalized, while minor words such as articles, conjunctions, and prepositions are usually lowercased (unless first or last).
Here are the practical rules most blogs follow. Capitalization rules vary by style guide, such as AP style, APA style, the Chicago Manual of Style, and MLA style (one reminder: especially with short prepositions).
| Element | Title case (common blog style) | Sentence case |
|---|---|---|
| First and last word | Capitalize | Capitalize first word (last word stays as written) |
| Major words (nouns, verbs, adjectives, adverbs, pronouns) | Capitalize | Lowercase (unless proper noun) |
| Articles (a, an, the) | Lowercase (unless first or last) | Lowercase (unless first word is “A/An/The”) |
| Short conjunctions (and, but, or, nor, for, so, yet) | Lowercase (unless first or last) | Lowercase |
| Short prepositions (in, on, to, of, at, by, for) | Often lowercase (unless first or last) | Lowercase |
| Proper nouns and brand names | Keep official capitalization (WordPress, iPhone, YouTube) | Same |
When in doubt, don’t “fix” brand styling. “iPhone” stays “iPhone” in both systems.
When to use each for blog titles (and a sensible default)
For most blogs, pick one default and stick to it. Consistency makes your site feel edited, and it keeps your archives from looking like a patchwork of different rules. Then override on purpose, not by accident.
A simple starting point: use title case for most marketing blog titles and evergreen blog content, and use sentence case when you want a calmer, more conversational tone (or when your product voice leans minimalist).
| Situation | Title case usually fits | Sentence case usually fits |
|---|---|---|
| “Big” evergreen guides and pillar pages | Yes, it reads like a headline | Sometimes, if your brand is understated |
| News, updates, and announcements | Sometimes | Yes, it feels direct and current |
| Thought pieces and opinion posts | Yes, if you want punch | Yes, if you want warmth and honesty |
| Technical documentation style posts | Sometimes | Yes, it scans like a sentence |
| UX writing, button labels, and interface-like tone | Sometimes | Often, for a quieter UI feel that supports visual hierarchy |
| Multi-author blogs with mixed editors | Yes, if you need a clear rule | Yes, if your workflow prefers fewer caps |
If your team writes for product surfaces too, sentence case often matches UI conventions. This UX-focused take on title case vs sentence case in UX writing captures the tradeoff well: title case can feel “louder,” sentence case can feel “steadier.”
A quick house style you can adopt today
If you want something you can paste into an editorial doc and move on, following a specific style guide like AP style helps maintain site-wide consistency:
- Default to title case for blog posts.
- Use sentence case for time-sensitive updates, release notes, and casual writing.
- In title case, keep a, an, the, and, but, or, for, nor, so, yet lowercase unless they’re the first or last word.
- Keep short prepositions (in, on, to, of, at, by, for) lowercase unless first or last, and don’t stress over edge cases as long as you stay consistent.
- Always respect proper nouns and official brand capitalization.

These examples illustrate composition titles in sentence case and title case. These capitalization rules also apply to email subjects to increase open rates. Regardless of the casing, the punctuation at the end of blog titles should remain consistent.
If you’re brainstorming headlines for a series, it helps to generate a batch, then apply your capitalization rule at the end. A tool like a Blog post title generator can speed up the “give me ten angles” part, then you choose what matches your voice.

Conclusion
The “right” choice in title case vs sentence case isn’t a secret rule, it’s the style that matches your brand and influences the overall look of headlines on the page. Pick a default, write a short house style guide, and only break it when you mean to. Then watch how readers respond, especially on pages where you can test titles and measure clicks with an eye on readability. Ultimately, consistency across all blog titles matters more than any specific style guide. Which style sounds more like your blog when you read it out loud?
