Sentence case is the standard for user interfaces, navigation menus, software documentation, and most British publications. Many technology companies mandate it for product copy.

When to use APA Style

APA Style is required for papers in psychology, education, sociology, and public health. It is the standard for dissertations in most social science departments.

All words after the first are lowercase unless they are proper nouns or follow a colon. This makes APA titles look significantly different from title-case styles.

When to use Sentence Case

Sentence case is the standard for user interfaces, navigation menus, software documentation, and most British publications. Many technology companies mandate it for product copy.

All words after the first are lowercase unless they are proper nouns. Common nouns, verbs, and adjectives are not capitalized.

Choosing between them

Choose APA Style when your target journal or institution specifies it, as it includes citation and formatting rules beyond capitalization.

Choose generic sentence case for digital interfaces, British publications, and contexts where only capitalization style is relevant.

Writers often use the terms interchangeably when discussing capitalization. In strict usage, APA Style implies the full publication manual, while sentence case is a standalone capitalization rule.
