Microsoft Outlook, the email client in Microsoft's Office widely used suite of productivity applications, offers users a variety of options to customise the experience of reading, writing and organising e-mail messages. One of the simplest ways to customise e-mails in Outlook is to change the font or font size used in e-mail messages. Permanently changing the font size of e-mails in Microsoft Outlook is not difficult to do, thanks to a simple set of menu options.

Skill level:


  1. 1

    Click the "Tools" menu at the top of your screen, then select "Options."

  2. 2

    Click the "Mail Format" tab, and then select the "Stationery and Fonts" tab.

  3. 3

    Click "Personal Stationery." View options to change the font and font size of e-mails you compose, read, reply to or forward to someone else.

  4. 4

    Click the "Font" button for the changes you would like to make. For example, to change the font size for e-mails you compose to others, click the "Font" button below the New Mail Messages option.

  5. 5

    Select the new font size you would like from the pop-up box. Click "OK" on this pop-up box, on the Stationery and Fonts box, and on the Options box.

Tips and warnings

  • Choose a common font when you change your font in Microsoft Outlook; according to Microsoft, recipients will not be able to read your message properly if you choose a unique font that they do not have.
  • Note that font size changes that you indicate in Microsoft Outlook will only apply to plain text e-mails. Messages in HTML format cannot change font size this way because of limitations in the coding of the email.
