Increase the Font Size in Email
Email font size is easily controlled while composing messages, but the messages you receive have been sized by the sender.
Some contacts may be perfectly comfortable writing in size 8, but such text can be a strain on the eyes, even with good reading glasses.
The printed hard copies of email messages with small text are even more difficult to read.

Click on the "View" selection from the menu bar.

Click on one of the choices that is greater than 100 percent.
Click "View" and cover "Zoom" to make a larger choice if the first choice does not increase the text size sufficiently.


Click the "View" option on the menu bar. Roll the cursor over the "Text Size" selection.
Choose one of the options that will increase the text size.
For instance, if the current size marked with the dot is "Medium," then click "Larger" or "Largest" to make the print appear bigger.

Use a mouse with a wheel to increase the email font size.
Press and hold the "Ctrl" key while rolling the wheel on the mouse.
The text will shrink as you roll in one direction, and grow bigger as you roll in the other.

Assuming you have a MS Windows OS. There are a couple of ways to remedy this situation. Option one is to change the screen resolution by right clicking on the desktop screen and selecting Properties and then Settings. Change the Screen Resolution to something lower than the current setting. This will cause everything to enlarge on the screen. Option 2 is to just change the font size as the standard. Right click on the desktop screen and select Properties. Select Appearance and change the Font Size to Large Fonts or Extra Large Fonts. If you are trying to change the font in Internet Explorer then choose View/Text Size, select Larger or Largest. That will change only the fonts inside Internet Explorer.
