Capitalization helps communicate the importance of specific words and can be used to indicate a change in meaning. To keep this effective, we need to limit what we capitalize.


  • As of February 2023, use title case for three types of UI content:
    • Page titles
    • Left navigation (main navigation)
    • Titles on All Capabilities page tiles
  • Use sentence case the rest of the time.
  • Capitalize the first letter of proper nouns (product names, countries, acronyms, and people's names) regardless of where they appear in a sentence.
  • Capitalize product names as described on the page Product and capabilities: capitalization, trademarks, and usage.
  • Don't capitalize articles (a, an, the) or prepositions (of, on, for, in, to, with, etc.) unless they're at the beginning of a sentence.

Units of measurement

Memory, bandwidth, and drive space abbreviations have varied rules for capitalization.

  • Always include a space between the value and unit of measurement.
  • A single bit of data is lowercase (b) whereas 1,204+ bits is sentence case (13 Kb).
  • Bytes are always uppercase (13 KB, 512 MB).

Weights and distance are lowercase with no periods after the abbreviation (ft, lbs, km).
