What sentence case means

Sentence case is the everyday way of writing English. Each sentence starts with a capital letter, and the remaining words are lowercase unless they are names. Emails, articles, text messages and most books are written this way.

It gets its name because it follows the rule for a sentence rather than the rule for a title. “The meeting starts at nine” is sentence case. “The Meeting Starts at Nine” is title case.

How this converter works

Paste your text and press Sentence case. On this page, pasted text is converted straight away. The tool then does four things:

  1. Makes every letter lowercase.
  2. Capitalizes the first letter of the text and the first letter after a full stop, question mark or exclamation mark.
  3. Capitalizes the first letter of each new line, which keeps lists and headings tidy.
  4. Restores the pronoun “I”, including “I’m”, “I’ll” and “I’ve”.

Abbreviations with dots such as “i.e.” and “e.g.” are not treated as the end of a sentence, so the word after them stays lowercase.

What you still need to check

No automatic tool can know which words are names. After converting, look for:

  • People and places: “we met sarah in london” needs two capitals.
  • Brands and products: iPhone, YouTube and similar names have their own spelling.
  • Acronyms: NASA, PDF and USA are lowercased along with everything else.
  • Days and months: Monday and October need a capital in English.

A quick read-through takes far less time than retyping the whole text.

Sentence case or title case?

Sentence case Title case
Example How to train your dragon How to Train Your Dragon
Used for Body text, emails, captions Headlines, book and film titles
Capitals First word and names only Every main word

Many companies now write buttons, menus and headings in sentence case because it reads more naturally. Google’s and Microsoft’s writing guides both recommend it for interface text. If you are unsure which to use for a heading, sentence case is the safer choice. For headlines, use the title case converter.

Common reasons to use it

  • You typed a paragraph with caps lock on and do not want to start again.
  • A client sent copy in ALL CAPS and it needs to go into a document.
  • A spreadsheet export has names or descriptions in capitals.
  • You are formatting article titles for an APA reference list.

Sentence Case Converter: questions and answers

What is sentence case?

Sentence case is the capitalization used in ordinary writing. The first word of each sentence starts with a capital letter and everything else is lowercase, apart from names and the pronoun I. This answer is written in sentence case.

Does the converter capitalize names and places?

No. A converter cannot tell that paris is a city or that apple is a company in your sentence, so proper nouns come out in lowercase. Read through the result once and capitalize names, places and brands by hand.

How do I convert text to sentence case in Word?

Select the text, open the Home tab, click the Change Case button (Aa) and choose Sentence case. You can also press Shift + F3 to cycle between cases. Word leaves existing capitals in place in some situations, so text typed in ALL CAPS is often easier to fix by pasting it here.

Do APA references use sentence case?

Yes. In APA style, the titles of articles and books in a reference list are written in sentence case: capitalize the first word, the first word after a colon, and proper nouns. Journal names keep title case.
