Type once and every case format updates instantly, each with its own Copy button. The Title Case here follows the actual rule — articles and short prepositions stay lower case, but verbs like is and are get capitals, which most converters get wrong.
| Case | Use it for | Avoid it for |
|---|---|---|
| Sentence case | Body text, headings on most modern sites, emails | Nothing much — it is the safe default |
| Title Case | Book and article titles, US-style headlines | Long headlines; it gets shouty |
| UPPERCASE | Short labels, buttons, one-word emphasis | Whole sentences — it reads as shouting and is slower to read |
| lowercase | Usernames, hashtags, a deliberate casual tone | Anything formal |
| snake_case | File names, database fields, Python | Anything a reader sees |
| kebab-case | Web addresses, CSS class names | Anything a reader sees |
| camelCase | JavaScript variables | Anything a reader sees |
Proper title case capitalises the first and last word, and everything in between except articles (a, an, the), coordinating conjunctions (and, but, or, nor, for, yet, so) and short prepositions (of, to, in, on, at, for, with, from, by).
Verbs are always capitalised, including short ones. "Is", "Are" and "Be" get capitals — a rule almost every automatic converter gets wrong. The converter above handles it correctly.
Capitalised Case, by contrast, capitalises every single word with no exceptions. It is what you want for a name badge, not for a headline.
Lower-case letters have ascenders and descenders — the tall stroke on an h, the tail on a g. Those give each word a distinct outline that readers recognise without reading letter by letter. Capitals are all the same height, so the outline disappears and reading slows measurably.
Use capitals for a word or two. Never for a paragraph.
What is the difference between Title Case and Capitalised Case? Title Case leaves articles, short conjunctions and short prepositions in lower case. Capitalised Case capitalises every single word with no exceptions.
Should is be capitalised in a title? Yes. It is a verb, and title case capitalises verbs however short they are. Many automatic converters get this wrong.
Why is uppercase text harder to read? Lower-case letters have ascenders and descenders that give each word a recognisable shape. Capitals are uniform in height, so that shape disappears and reading slows.
What is snake_case for? File names, database columns and Python variables. Kebab-case is the same idea for web addresses and CSS class names.
