“Title Case” vs. ​“Sentence Case”

When we say ​“title case,” we’re refer­ring to con­tent where near­ly all of the words start with a cap­i­tal let­ter. Title case applies most­ly to copy in head­lines and buttons.

“Sentence case” is when you cap­i­tal­ize con­tent like it’s a sen­tence — only the first let­ter of the first word is cap­i­tal­ized, along with any prop­er nouns.
