Capitalization

Learn when and when not to capitalize.

Use sentence-style capitalization for all content including titles and subtitles. Capitalize the first letter of the first word and use lowercase thereafter.

Guidelines:

• Capitalize the first word of a sentence, heading, title, UI label, or standalone phrase.
• Capitalize proper nouns. Use lowercase for everything else.
• Always capitalize the first word of a new sentence. Rewrite sentences that start with a word that is always lowercase.
• Don't use all uppercase for emphasis.
• Don't use all lowercase or all uppercase as a design choice.
• When words are joined by a slash, if the word before the slash is capitalized, capitalize the word after the slash. Examples: "Country/Region", "Turn on the On/Off toggle".

Exceptions

Proper nouns, including brand, product, and service names, are always capitalized. If a title or heading includes a colon, capitalize the first word after it.
