Selection.Range.Case = wdUpperCaseWhen to Use UPPERCASE
Headlines and titles. ALL CAPS headlines grab attention in banners, posters, and social media graphics. They’re especially effective for short, punchy phrases.
Important notices. Warnings, disclaimers, and legal text often use uppercase for emphasis: “DO NOT REMOVE THIS TAG.” This convention signals that the reader should pay close attention.
Acronyms. NASA, FBI, HTML — acronyms are conventionally uppercase. When writing about organizations or technical terms, keep their standard uppercase form.
Form labels. Many web forms use uppercase labels for a clean, structured look that distinguishes labels from input values.
Emphasis in text. Use sparingly — a single uppercase word in a sentence adds strong emphasis without overwhelming the reader.
When NOT to Use UPPERCASE
Body text. Entire paragraphs in uppercase are hard to read. Studies show uppercase text reduces reading speed by ~10%.
Professional emails. ALL CAPS in emails reads as shouting (like leaving caps lock on accidentally). Use sparingly — one uppercase word for emphasis is fine, entire sentences are not.
SEO titles. While uppercase can stand out, overuse in title tags looks spammy to both users and search engines.
Uppercase vs Other Cases
| Case | Example | Best for |
|---|---|---|
| UPPERCASE | HELLO WORLD | Headlines, warnings, acronyms |
| lowercase | hello world | URLs, code, casual text |
| Title Case | Hello World | Book titles, headings |
| Sentence case | Hello world | Normal sentences, body text |
| Capitalize text | Hello World | Names, proper nouns |
Convert from upper case to lower case when you receive text that’s SHOUTING — paste it into the case converter and click lowercase.
Convert caps to lowercase is equally useful for cleaning up text copied from PDFs or scanned documents that came out in all caps.
Title Capitalization Rules
Title case has specific rules that trip people up. Note: this is different from just hitting caps lock — title case selectively capitalizes.
Do you capitalize “in” in titles? The question “do you capitalize in in titles” comes up often. Answer: no — short prepositions (in, on, at, to, of) stay lowercase in title case (Chicago/AP style).
Should a be capitalized in a title? No — articles (a, an, the) are lowercase unless they’re the first word of the title.
Should with be capitalized in a title? It depends: Chicago style lowercases all prepositions; AP style capitalizes prepositions of 4+ letters (so “With” is capitalized in AP). When in doubt, use a title case converter.
Do you capitalize “are” in a title? Yes — verbs are always capitalized in title case, even short ones (is, are, be).
