Question

I am new to Ubuntu and having issue to set the System font size in 15.04. Can I set it from System Settings?

OR I have to install tool for it?

Answer 1

If you want to change the Document fonts, you don't need any other tools. just open the system settings, go to Text Entry and there you can change the Font family and the font size. the left bottom corner.

To change system fonts you need unity-tweak-tool

sudo apt-get install unity-tweak-tool

Open fonts from appearance tab and choose what you want

Another Option to use

you can also use gnome-tweak-tool:

sudo apt-get install gnome-tweak-tool 

Go to Fonts tab on the left panel then choose what font to change

Answer 2

Try this: Turning-on-off button in the upper right corner of screen, System settings, Display, Scale for menu and tittle bars. Here the scaling factor of entire GUI can be changed. I have tested it in Ubuntu 14.04 and 16.04. I think it will work also in 15.04.

Answer 3

You need an extra tool.

Get the Unity Tweak Tool. Open a terminal and install with

sudo apt-get install unity-tweak-tool

Start it with Unity Tweak Tool, click Fonts in the category Appearance and set the sizes.

Tested on 14.04.
