How to change text size and font

Changing the text in your documents can help to make your creations more interesting and eye-catching.

Text can be changed to many different sizes and styles.


This guide explains how to change text size and font style in Microsoft Word. It will feature Word 2010, but the process is similar for both earlier and later versions of Word. For other version please visit the Microsoft Word support site.

You’ll need:

  • A computer with Microsoft Word installed.

Follow these step-by-step instructions to change text size and font

Step 1: Open an existing Word document or start a new document and type your text.


Step 2: If you’d like to change a portion of the text to a different font, it will need to be selected or highlighted first. When the mouse pointer is moved over a text area, it will change from an arrow to a ‘text select’ or ‘I-beam’ icon.
