Title Case capitalizes the main words in a heading while keeping small connector words lowercase, unless they start the sentence. It’s the standard for headlines, book titles, and most heading tags in Western publishing.

The rule that trips people up

Title Case isn’t “capitalize every word.” Short conjunctions, articles, and prepositions such as a, an, the, and, but, or, of, in, on usually stay lowercase unless they’re the first or last word of the title.

How to convert it

Paste your heading into BizTextFormat‘s case converter and select Title Case — it applies standard capitalization rules automatically, including the small-word exceptions.
For a quick manual check: capitalize the first and last word always, then capitalize every word 4+ letters, and leave short connector words lowercase.

When to skip Title Case

Sentence case, capitalizing only the first word, is now standard for most web UI — buttons, form labels, many blog headlines — because it reads faster and feels less formal. If your brand voice is conversational, Sentence case usually outperforms Title Case in headline testing. Use Title Case for formal documents and press releases; use Sentence case for everyday web copy.
