When to Use Title Case vs. Sentence Case

Title Case and Sentence case look similar but follow different rules. Title Case capitalizes the first letter of every major word — typically used for blog post headings, article titles, book titles, email subject lines, and navigation menu items. Most style guides (AP, Chicago, APA) capitalize nouns, verbs, adjectives, and adverbs but leave articles, prepositions, and short conjunctions lowercase. Sentence case capitalizes only the first word of each sentence and any proper nouns — this is the standard for body text, product descriptions, social media captions, and most conversational contexts. If you are writing a news headline or a page title, Title Case is typically expected. For everything else, Sentence case reads more naturally.

camelCase, snake_case, and kebab-case Explained

These three formats are used in programming and web development rather than natural language writing. camelCase joins words without spaces and capitalizes each new word after the first — for example, myVariableName or getUserData. It is commonly used for JavaScript variables, function names, and JSON property keys. snake_case joins words with underscores and keeps everything lowercase — for example,my_variable_name. It is the convention in Python variables and database column names. kebab-case uses hyphens instead of underscores — for example,my-variable-name. It is the standard for CSS class names, HTML attributes, and URL slugs. Use this tool to quickly convert any phrase into the correct format for your project without manually retyping it.
