Mailbird scaling feature allows the user to adjust the size of the UI.

Here's what to do:

1) Go to the menu in the top left of the Mailbird window.

2) Select "Settings"

3) Then select "Appearance" tab.

As you can see we have 2 different levels of scaling, the app and the other.

The "Application scaling level"

Use the slider from left to right to adjust the level. It will scale the entire UI


The "Other scaling levels"

The individual scaling for email and apps will be still available and it will multiply the value by the whole scaling

Use the slider from left to right to adjust the text in your messages.


You can see the text in your messages increase or decrease when sliding the scaling bar from left to right.

You can also change the scaling of your apps. Do the same ways, use the slider from left to right to adjust the scaling level.


There is also scaling indicator in the top right of conversation. It will show up when you change the value or when you hover over the area. If you click it, it will reset the scaling to 100%. Please note this indicator is only for the email, not for the whole UI.


There is scaling indicator too in the bottom right of 3rd party apps. Same with the email scaling, this indicator not for the whole UI.

    Agree with Najib and Barbara, message list is too small. Mailbird needs to do something about it, otherwise this app won't work for me.

    I looks like I will have to abandon Mailbird for the same reason that I have abandoned many other apps: fonts are impossibly small on screen. I can zoom an email message contents with Ctrl-+ and I can set zoom levels for messages and apps from Settings. However, the message list is too small to read and I see no way to change the font size for it. This is real shame as Mailbird looks like the perfect app to handle a Gmail account.

    I agree Najib.

    I like Mailbird a lot but the fonts are to small and light for me. The message lists and my folder lists are just too small for me to read. Bummer, really!

    Let me know if you find anythign more suitable

    You were right, I was wrong, I appeared to me that the menu was salient to the messages themselves rather than the inbox but if I was right,
