1Material Design's Choice

Google's Material Design has explicitly recommended sentence case for all UI elements since Material Design 2. It aligns with conversational, human-centred design.

2Readability Research

Eye-tracking studies show sentence case is processed faster than title case in UI contexts — fewer capital letters reduce cognitive load.

3Exceptions

Proper nouns (product names, brand names) and abbreviations (OK, URL) remain capitalised even in sentence case contexts.
