Title Case vs Sentence Case: Which to Use for Headlines

Every headline has to be capitalized one way or another, and the choice is less obvious than it looks. Title case vs sentence case is a question writers, editors and site owners meet every day: do you write "How to Make a Strong Password" or "How to make a strong password"? This guide explains both styles, shows them side by side, and helps you pick one and keep it.

What title case means

In title case, the important words in a headline start with a capital letter. Small connecting words such as "a", "the", "of" and "and" stay lowercase unless they come first or last. The result looks formal and traditional:

You will see it on book titles, magazine covers and many article headlines.

What sentence case means

In sentence case, you capitalize a headline like a normal sentence: the first word gets a capital letter, and so do proper names. Everything else stays lowercase:

Many websites and apps now prefer it, because it looks calmer and reads more like speech.

Title case vs sentence case, side by side

Here is one headline run through our case converter in three styles:

The third row is not title case in the traditional sense. It simply capitalizes every word, including "in" and "of". It is simple and predictable, and some menus and product lists use it, but most editors do not treat it as proper headline style.

When to use title case

• Book, film and article titles, where tradition expects it.
• Formal documents and reports, where a traditional look suits the tone.
• Publications whose style guide asks for it. If an editor gives you a guide, follow it.

When to use sentence case

• Web pages, apps and help articles, where a friendly, direct tone works best.
• Headings inside long text, because they read like the sentences around them.
• Buttons and menu labels, where short, plain wording is easier to scan.
• Long headlines, since a sentence that is mostly lowercase is easier to read.

Why style guides disagree

There is no single correct title case. Newspaper, academic and publishing style guides differ on small details, such as which short words stay lowercase, whether a long preposition gets a capital, and how to treat words after a colon. A rule you read in one guide may be wrong in another.

That is why the best answer is usually practical: choose one style for your site, write down the few rules you follow, and apply them everywhere. Consistency matters more than which style you pick.

How to apply a style in seconds

Our converter follows one simple, documented rule set. In title case, the first and last word are capitalized, and so is the first word after a colon or a full stop. Words like "a", "an", "the", "and", "but", "or", "for", "nor", "on", "at", "to", "from", "by", "of", "in", "with", "as", "vs" and "via" stay lowercase in the middle of a headline.

To use it:

1. Paste your headline into the converter.
2. Choose Title Case or Sentence case.
3. Tick Keep ALL-CAPS words if your headline has acronyms such as NASA that must not change.
4. Copy the result.

Afterwards, you can check the length of the headline, which matters for search titles and social posts. For related advice on page titles, read keeping page titles and descriptions the right length. The same converter also handles the styles used in code, covered in naming styles such as camelCase and snake_case.

Mistakes to avoid

• Mixing styles on one site. A page titled in sentence case next to one in title case looks careless.
• Capitalizing every word and calling it title case. The small words should stay lowercase.
• Lowercasing names and acronyms. Sentence case still capitalizes proper names.
• Forgetting the word after a colon. In title case it normally starts with a capital.
• Trusting automatic conversion blindly. Names such as iPhone have their own spelling, so check the result.

Common questions

When should I use sentence case?

Use it when you want a friendly, readable tone, such as for web pages, app screens and help articles. It is also easy to apply, because you only need to remember names and the first word.

Which words are not capitalized in a title?

Usually short articles, conjunctions and prepositions, such as "a", "the", "and", "of" and "in", unless they are the first or last word. Style guides vary on the exact list.

What is the difference between title case and capitalize each word?

Title case keeps the small words lowercase. Capitalize Each Word puts a capital on every word, including the small ones.

Is one style better for search results?

We are not aware of any rule that says one capitalization style ranks better. Choose the one that fits your site and use it consistently.

Can I switch styles later?

Yes, and a converter makes it quick. Paste your headlines, choose the style and copy them back. Just change them all at once so the site stays consistent.
