How do I reduce the font size on tabs in Chrome in Ubuntu?

Solution 1:

Click with the right button of mouse on the Chrome shortcut and "Properties".

Use this: chromium-browser --force-device-scale-factor=0.5

Now you can scale whatever you want, even bigger shit like factor=2 :D

I found something of a workaround for my own system. You probably know about your ~/.Xdefaults file, Well, it turns out there is a default value that helps. Modify the file, and reload using the command xrdb -load ~/.Xdefaults. Then restart Chrome browser, and, -- voila -- the tab font got larger. The lines I added are as follows:

!! Xft settings help the problem with small font in google chromium tabs! 
!! Xft.dpi: 96  is the setting that makes the tab font larger 
Xft.dpi: 96 
Xft.antialias: true 
Xft.rgba: rgb 
Xft.hinting: true 
Xft.hintstyle: hintslight 

I found the above in a thread where people were talking about improving the appearance of fonts in chrome on Linux, and discovered that the 96dpi setting has the side-effect of increasing the font size on the tabs. I should say that I am NOT a font expert, so I cannot guarantee this will work on any system (possible depending on what fonts you have installed?), but I'd say it is quick and worth a try.

Solution 3:

For window managers that do not handle the font settings correctly, you can use your ~/.Xdefaults file. Set Xft.dpi to e.g. 96:

Xft.dpi: 96

And issue the command xrdb -merge ~/.Xdefaults. Then restart your browser to see the effects of the settings. Tweak the dpi value until you are satisfied.
