Cheat Sheet on Capitalization Rules

When it comes to capitalization, English rules can seem complex and convoluted at first. However, they boil down to bringing structure, clarity, and consistency to our writing. Getting capitalization right polished your work and makes reading smooth.

The Key Capitalization Guidelines:

  • Capitalize the first word of every sentence and all proper nouns like people’s names, days, months, cities, states, etc.
  • Capitalize official titles when used before a name, like President Biden or Dr. Jones.
  • Capitalize the main words in book titles, movie titles, song names excluding small articles/prepositions like “and” “of”.
  • Capitalize the first letter of every point in a bulleted list or outline structure – like what you are reading now!
  • Capitalize brands, companies, product names and trademarks to match their official upper case letter styling.

Tips and tricks for SEO

Here are some handy tips and tricks users can utilize when using the case converter tool:

  • Copy and paste longer excerpts rather than retyping the entire text to save time. The tool preserves all spacing and punctuation.

    Double check for any misspellings or typos before converting, as it will preserve these. Use built-in spellcheck if unsure.

    For long documents, convert section-by-section rather than all at once if needed. Breaking it up minimizes risk.

    Want a creative flourish? Mix and match! Convert the first paragraph to lowercase, leave the second as is, and make the third uppercase.

  • Be mindful of links or email addresses when converting, as those may need to remain uppercase for functionality.

    For branding purposes, exceptions can be made to company names or product names that legally require specific capitalized formatting.

    Unsure which style looks best? The tool allows experimenting with different case options on your text before settling on a final pick.

    If copying from another source, it may carry over unwanted formatting. Paste into Notepad first then recopy plain text.
