A Guide to the Different Text Cases

Understanding each case helps you choose the right format. Here’s what each option does:

Sentence case

This is the standard for most writing. It capitalizes the first letter of each sentence and any proper nouns. It's the most readable format for paragraphs and is ideal for blogs, articles, and emails.

lowercase

this converts every single letter to its small-letter form. it's widely used for technical purposes like url slugs or in programming languages, and sometimes for stylistic, informal branding.

UPPERCASE

THIS CONVERTS EVERY LETTER TO A CAPITAL. UPPERCASE IS USED FOR STRONG EMPHASIS, ACRONYMS (E.G., NASA, SEO), AND IN LEGAL DOCUMENTS. USE IT SPARINGLY IN GENERAL TEXT TO AVOID "SHOUTING" AT YOUR READERS.

Capitalized Case (Title Case)

This Capitalizes The First Letter Of Every Major Word. It's the standard for titles of books, articles, and blog posts, making headings stand out from the main text.
