Title case vs sentence case: which should you use?
Case style changes the tone of a heading, button, title, or label. The best choice depends on the context.
Title case capitalizes the main words in a phrase. Sentence case capitalizes only the first word and proper nouns. Both styles are common, but they create different impressions.
Title case often feels formal, polished, or editorial. Sentence case feels conversational and easy to scan. Many modern product interfaces use sentence case for buttons, settings, and short labels because it is less visually noisy.
Where title case works well
- Article titles when your style guide prefers it.
- Book, report, or presentation titles.
- Navigation labels in some branded sites.
- Marketing headings that need a stronger editorial feel.
Where sentence case works well
- Buttons and form labels.
- Error messages and helper text.
- Documentation headings.
- Product UI and settings pages.
The most important rule is consistency. Mixing styles randomly makes a page feel unfinished. If your headings use sentence case, keep that pattern across the page.
How to convert text quickly
Paste the text into the Case Converter and choose the style you need. Then read the result once before publishing. Automated case conversion may not know whether a brand name, acronym, or proper noun needs special capitalization.
For web pages, sentence case is usually a safe default because it is readable and calm. Use title case when the page title itself needs a more formal style.
