When you compose an email message in GMail, it’s default font chosen by GMail. You can change text style like font, size, color etc while composing the message. But if you would like to enable a particular Font Style permanently for your GMail Messages, GMail also has a tool for that.
‘Default Text Style‘ is a GMail Lab Feature which once enabled and set will make sure that every message you send has a default font style that you have chosen. To use this functionality, Go to Gmail Settings > Labs. When you scroll down you will find ‘Default Text Styling’. As this an experimental Lab feature, it is disabled by default. Click on ‘Enable‘ and then scroll down and hit ‘ Save Changes‘.
After enabling the lab feature, Go to Settings > General . Here there will be a new option for Default Text Style and you can here set a default font style for your messages. You can use bold, italics, Font Style, Font Size, Change Font Color and reset the formatting too. All the changes that you made will be shown in a preview text below it, so that you know how your new GMail message will look like.
Once you are satisfied with the settings, scroll down and Save Changes. Next time onwards whenever you compose a new Gmail Message, this text style will be default and you will be able to send messages in your personalized font style. Remember , you can always change this style in compose box and use ‘Default Text Styling’ to modify the default font style . You can also disable this feature in GMail Labs.
