How to Change Font Size in Outlook

Do you want your email to look special? Outlook is a convenient system, but its default fonts may be dull. If they no longer suit your needs, follow the steps below. Font customization is relatively easy.

You can increase text size in Outlook or change the style — the choice is yours. It is only limited by fonts installed in your machine. If you need something really fancy, you need to find it online and install it first. What you do next depends on your version of the mail client.

Scope of Changes

Do you need to change the look of one email? The parameters can be changed in the message window. To make all emails look the same, alter your system settings. Follow our roadmap to learn how to change font size in Outlook.

Change Font Size in Outlook 2010-2019

The following steps apply to all versions after and including 2010. Please note that in the 2010 version the screens and options may look a little different. However, you can still navigate the system easily. All the locations, buttons, and functions are shared by all subsequent versions. So, here, is what you should do.

Follow these steps to adjust the font size in an email you’re writing in Outlook:

  1. Highlight the text you’d like to adjust.
  2. In the Message tab, in Basic Text group, adjust the numbered drop-down box to your preference.
  3. Alternatively, in the Format Text tab, in the Font group, adjust the numbered drop-down box to your preference.

Follow these steps to adjust default font size for messages you are composing:

  1. Open the Options window from the File menu.
  2. In the category list on the left, choose the “Mail“.
  3. Press the “Stationery and Fonts” button on the right.

Now, you can assign the desired font to separate groups. Different settings may be chosen for new emails that you type, forwarded messages, replies, and plain text. Here is how this works.

  • Changes to new messages mean that your default font will be replaced.
  • Changes for replies and forwarding means that when you forward an email or reply to it, the font will change.
  • With plain text, it is different: font changes apply to messages viewed by you. Other people will still see them as plain text.
  • Clicking on each of the “Font” buttons opens an eponymous window. There, you may set special parameters for the body and headings, and view sample text. You may change the spacing on the “Advanced” tab.
  • Clicking on the ‘Theme’ button at the top allows you to disable the current theme for HTML messages, or set a new one. The action opens a new window where you can view all available themes, pick one, or choose “No Theme” to disable it.
  • Every theme includes a special font, sizing, color, and effects. Choosing a theme disables the choice described above, as all the properties are auto-defined.
  • Click on OK on each of the open windows to close it. Now, your font preferences have been changed!
