Increase SourceTree font size

Is there any way to increase the font size in SourceTree for OS X? Currently, the font size it uses is so tiny that my eyes hurt a lot after a while managing branches.

I was hoping more people would have voted for this. I really can't use the font size as it is now. It is positively miniscule. I've never seen any Mac app with a font this small - surely it breaks some standard?

A preference to change it doesn't seem like much?

Not a complete solution, but I just found that you can at least change the diff font size by going to `SourceTree -> Preferences -> Diff tab`. 

this works great!  thanks so much for the answer Jeffrey!  

on Mac:


`SourceTree -> Preferences -> Diff tab`

Lol, I switched to using the command line ages ago.

Almost 2 years since I posted my answer and still nothing. I even told them about it in person at WWDC last year and they said they would pass the message on...

It would be cool to add a custom font size adjustment

Since on windows are also bad..



I agree.  This needs to be fixed so the font can be adjusted.  SourceTree is unusable currently.  On my monitor the SourceTree font measures equivalent to a 5pt font.

The new dark UI helps readability but the text is so, so small. Taking hi resolution monitors into consideration for UI to allow for some type of scaling and font sizing would go a long way in ease of use.

Is there any word on this feature?

Please increase font size. It's weird-ously small for HDPI monitors. So I started to use Sublime Merge, which resembles the Tower.

This app is unusable for me because of the small font size, it's a shame because it seems like it would be very helpful.

Come on Atlassian, it's 2020 already. Add the ability to increase Sourcetree's font size for crying out loud. So many other Windows application UIs let me hold down the Ctrl key while spinning the mouse wheel to increase/decrease the font size. That should be your goal when addressing this issue. PLEASE. This feature was requested four years ago! I suppose your silence on this thread implies that it isn't going to happen? That'd be a real shame.

On HiDPI screens this is a serious defect.

We cannot read the text without an external LCD non-HiDPI monitor.

It's incredible how something so simple, yet so important can't be achieved by the SourceTree Team 

I can't believe this hasn't been addressed yet. Sourcetree remains unusable for me.

For me too. You're not alone.

Hello Atlassian developers,

Are there any actions in this direction?

Increasing font-size would be really useful feature in Windows or in Mac OS.


I have the same problem. I have to use a 14" laptop momentarily, and I feel like I'm going blind.

Big +1 for this feature request

Since this dates since 2016 I assume there is no possibility of a future fix. The app works fine on a 27" HD monitor but as people here commented if you are on a 15" Macbook retina you'll practically see nothing.

It is a shame the devs have ignored such a critical thing (reading simple text!)

Another request to control Sourcetree's font size (not just for diff)

Please Atlassian

A minor request is getting unheeded by Atlassian.  Even a reply as to why this is ignored or when i may be prioritized would be awesome.

Any news on this?

This is embarrassing, Atlassian.

still no solution? I just cannot understand how such feature can be seen as minor issue. I'm often bumping into such problems lately in Sourcetree and others similar tools. And of all OS , on MacOS which I thought was the best when it comes to GUI/user-friendliness (yes I know Sourcetree is not developed by Apple, I'm just talking about the style guides and such)

please support changing  font size !

As by 2021 a lot of developers switch to 4k monitors.

5 years passed and still there is no option to adjust at least font size in SourceTree. I guess it's time to evaluate alternatives.


I have this issue now too. My troubles with Sourcetree started after upgrading my display to 49" ultrawide, which gives me 5120x1440 but renders the application unusable.

I'm gonna go evaluate GitKraken now.
