The default font size on a computer is based on a multiplier of your monitor's screen resolution. While the preset font size is designed to appeal to a majority of users, for some users, the default font size is too large or too small for comfortable reading. However, you can increase or decrease the size of the fonts on your computer to make it more comfortable to read.

Windows Operating System

Click the "Start" button.

Type "Text" in the Search box and press the "Enter" key. This opens a Text properties window. This window contains three size options for fonts on your screen.

Click in the radio button next to "Medium" or "Larger" to increase the font size; click in the radio button next to "Smaller" to decrease the font size. Click the "Apply" button to save your change. This displays a confirmation dialog.

Click the "Log off Now" button on the confirmation dialog to apply the change.

Internet Explorer

Open Internet Explorer.

Press the "F10" keyboard key. This displays a menu bar at the top of the screen.

Click "View," then move your mouse over "Text Size." This populates a submenu containing several size options.

Click to choose "Large" or "Larger to magnify the size of font on visited sites; click "Smaller" or "Smallest" to decrease font size. The change takes effect immediately.
