You can convert small letters to capital letters in Microsoft Word in two main ways: using a menu button or a keyboard shortcut.

Main Methods (Quick Scoop)

1. Using the Change Case button (Home tab)

  1. Select the text you want to change.
  1. Go to the Home tab.
  1. In the Font group, click the Change Case button (it usually shows “Aa”).
  1. Choose UPPERCASE from the list.

Your selected text will instantly change from small letters to capital letters.

You can also pick:

  • Sentence case (only first word of sentence capital).
  • lowercase (everything small).
  • Capitalize Each Word (each word starts with a capital).

2. Using the keyboard shortcut (faster)

  1. Select the text you want to convert.
  1. Press Shift + F3 on your keyboard.

Each time you press Shift + F3 , Word cycles the text through:

  • lowercase
  • UPPERCASE
  • Sentence case

So keep pressing until you get full capitals.

3. Extra option: “All caps” formatting

Some versions or tutorials also mention:

  • Selecting text, opening the Font dialog, and turning on “All caps,” or using a shortcut like Ctrl + Shift + A to format as uppercase.

This keeps the letters visually capital without changing the underlying text characters (useful for design and headings).

In forum discussions and how‑to videos from 2024–2025, the most recommended everyday trick is simply: select text → press Shift + F3 until it’s all caps.

TL;DR:

  • For menu: Home → Change Case → UPPERCASE.
  • For shortcut: select text → Shift + F3 until it shows in capitals.
