A title case converter capitalizes the first letter of every major word in a title or heading. It is the standard capitalization format for book titles, article headlines, and film names in American English.
Title case capitalizes every significant word in a title, including nouns, verbs, adjectives, and adverbs. Short articles, coordinating conjunctions, and prepositions are typically left lowercase unless they appear at the start or end of the title.
The first word and last word of any title are always capitalized, regardless of their part of speech. This ensures that even a short preposition like "in" gets capitalized when it opens or closes a title.
Title case is the default format for book titles, film titles, album names, and newspaper headlines in the United States. It signals that a phrase is a proper title rather than ordinary running prose.
Most American publishers, including major newspapers and academic journals, default to some form of title case for headlines and headings. The specific rules vary by style guide, but the convention of capitalizing major words is universal.
Every noun, verb, adjective, and adverb in a title should be capitalized. The words "a," "an," and "the" stay lowercase unless they are the first or last word.
Coordinating conjunctions such as "and," "but," "or," "nor," and "for" are lowercase in standard title case. Short prepositions like "in," "on," and "at" are also lowercased by most style guides.
Sentence case capitalizes only the first word of a title and any proper nouns, making it less formal than title case. AP Style, Chicago Style, and MLA Style are all variations of title case with slightly different rules about which words to lowercase.
Understanding the differences helps you choose the right format for your context. Academic papers, journalism, and legal documents each favor different capitalization conventions, and the wrong one can mark your work as unprofessional.
