The quickest way to capitalize each word

Microsoft Word has a built-in text case tool that changes capitalization without retyping. Select the text you want to change, then go to the Home tab, find the Aa button (labeled "Change Case"), and choose Capitalize Each Word from the dropdown menu. Word will capitalize the first letter of every word in your selection when ready.

This feature works on text you've already typed or pasted into your document. It does not affect text in headers, footers, or text boxes unless you select and change those separately. The change applies only to what you have highlighted — the rest of your document stays the same.

Key Takeaways

  • Select your text first, then use Home tab > Change Case (Aa button) > Capitalize Each Word to capitalize every word at once.
  • The Change Case tool works on any text you can highlight, including pasted content, but does not affect unselected portions of your document.
  • If you cannot find the Aa button, your version of Word may have the option under Format > Text instead.
  • Capitalizing each word is useful for titles and headings, but Word will capitalize small words like "and" and "the" — you may need to fix those by hand afterward.

Where to find the Change Case button in different Word versions

The location of the Change Case tool varies slightly depending on whether you use Word on Windows, Mac, or the web version. On Windows and Mac desktop versions, the Aa button sits on the Home tab in the ribbon at the top of the screen, usually near the font color and highlighting tools. Click the small arrow next to it to see all case options.

In Word Online (the browser version), the Change Case button is also on the Home tab, but the ribbon is more compact. If you do not see the Aa button when ready, look for Format in the menu bar, then select Text and look for case options there. Some older versions of Word place this feature under Format > Change Case instead of on the ribbon.

What happens when you capitalize each word

When you explore Capitalize Each Word, Word puts a capital letter at the start of every word and makes all other letters lowercase. This means "the quick brown fox" becomes "The Quick Brown Fox." The tool treats hyphenated words as two separate words, so "mother-in-law" becomes "Mother-In-Law."

Word capitalizes every word, including small connecting words like "and," "the," "of," and "in." If you are creating a title or heading that follows a style guide (like AP or Chicago style), those guides usually say not to capitalize small words in the middle of a title. You will need to go back and fix those by hand after using the tool — Word does not know which words should stay lowercase.

Step-by-step: Capitalizing text in your document

Step 1: Click at the beginning of the text you want to change. Hold down your mouse button and drag to the end of the text, or triple-click to select an entire paragraph. The selected text will appear highlighted in blue.

Step 2: Go to the Home tab at the top of your screen. Look for the Aa button with a small downward arrow next to it. This button is usually in the middle section of the ribbon, near font formatting tools.

Step 3: Click the small arrow next to the Aa button to open the dropdown menu. You will see five options: Sentence case, lowercase, UPPERCASE, Capitalize Each Word, and tOGGLE cASE.

Step 4: Click Capitalize Each Word. Your selected text will change when ready. Click somewhere else in your document to deselect the text and see the final result.

Other capitalization options Word offers

The Change Case menu gives you four other options besides Capitalize Each Word. Sentence case capitalizes only the first letter of the first word and any proper nouns, which is useful for regular paragraphs. lowercase makes everything lowercase, and UPPERCASE makes everything capital letters. tOGGLE cASE flips whatever case each letter already has — uppercase becomes lowercase and vice versa.

Sentence case is often the best choice if you accidentally capitalized too much text in a paragraph. UPPERCASE is useful for acronyms or emphasis, though it can be hard to read in large blocks. Most people use Capitalize Each Word only for titles, headings, or special formatting where that style makes sense.

Why you might need to edit after capitalizing

The Capitalize Each Word tool does exactly what its name says — it capitalizes every word without judgment. That works perfectly for some titles, but many style guides and writing standards say small words should stay lowercase in the middle of a title. Words like "a," "an," "the," "and," "but," "or," "in," "on," "at," and "to" are usually lowercase unless they are the first word of the title.

After you use the tool, scan your title and fix any small words that should be lowercase. This takes only a few seconds and ensures your document follows the style you intended. If you are writing for a specific organization or publication, check their style guide first to see which words they want capitalized.

Frequently Asked Questions

Can I undo the capitalization if I change my mind?

Yes. Press Ctrl+Z (Windows) or Command+Z (Mac) when ready after making the change, and Word will undo it. If you have made other changes since then, you can still undo by going to File > Info > Version History (in Word Online) or by using the Undo button in the top left corner of your screen.

Does the Change Case tool work on text in tables or text boxes?

Yes, as long as you select the text first. Click inside the table cell or text box, highlight the text you want to change, then use the Change Case tool the same way you would for regular document text. Each selection is changed independently.

What if the Aa button is not visible on my Home tab?

Your version of Word may have the feature in a different location. Try clicking the Format menu at the top, then look for Text or Change Case. If you still cannot find it, you may be using an older version of Word that does not have this feature — in that case, you can manually capitalize each word or copy the text into a newer version of Word.

Will capitalizing each word affect my document's spell check?

No. Word's spell checker will still work normally after you change the case. However, if you capitalize a word that is usually lowercase (like "the"), Word may flag it as unusual, depending on your spell-check settings. This is just a notification and does not change your document.
