Title Case vs Sentence Case
Title case capitalizes the main words of a heading, such as "How to Grow a YouTube Channel". Sentence case capitalizes only the first word and proper nouns, such as "How to grow a YouTube channel". Use title case for blog headings, book names, and video titles. Use sentence case for descriptions, captions, and normal paragraphs.
Standard style
Keeps short articles, conjunctions, and prepositions lowercase unless they start or end the title.
AP style
Lowercases only short words of three letters or fewer, so words like "with" and "from" are capitalized.
Capitalize Every Word
