The five cases

Case	Example
UPPER CASE	THE END OF THE ROAD: A STORY
lower case	the end of the road: a story
Title Case	The End of the Road: A Story
Sentence case	The end of the road: a story
Capitalized Case	The End Of The Road: A Story

Title Case rules

Title Case gives a capital to every word except the small ones: articles (a, an, the), short conjunctions (and, but, or, nor, for, so, yet) and short prepositions (as, at, by, in, of, off, on, per, to, up, via). A small word still gets a capital when it’s the first or last word of a title, or the first word after a colon. Each line counts as its own title, so you can convert a list of headings at once.

Style guides differ a little. AP and APA give a capital to every word of four letters or more, as this tool does with “With” and “From”. Chicago keeps all prepositions in lowercase, even long ones like “between”. If you write for a publication, check its guide.

For example, “a guide to the best walks in the lake district” becomes “A Guide to the Best Walks in the Lake District”.

Sentence case and names

Sentence case lowercases everything, then gives a capital to the first letter of each sentence and each line, and to “I” on its own. “i think we’re ready. are you?” becomes “I think we’re ready. Are you?”

The tool can’t know which words are names, so “we met anna in paris” becomes “We met anna in paris”. Fix names, places and acronyms by hand after the change, or press Undo. After an abbreviation like “e.g.” followed by a space, it may add a capital you don’t want.

Fixing text typed with caps lock

Typed a paragraph with caps lock on? It may look like “hELLO, cAN YOU SEND ME THE FILE?” Press Sentence case, and it becomes “Hello, can you send me the file?” For a heading, press Title Case; for text that should be all small letters, lower case.

Where each case is used

• UPPER CASE: short labels, warnings and acronyms. Long text in capitals is hard to read and reads as shouting.
• lower case: email addresses, web addresses, hashtags and usernames.
• Title Case: titles of books, films and songs, and headlines in many American publications.
• Sentence case: ordinary writing, most headings on the web, buttons and menus in apps, and headlines in many British publications.
• Capitalized Case: a list of names typed in lowercase (“anna smith” becomes “Anna Smith”), and some labels and headings.
