Adjust the Launcher Icon Size

Ubuntu includes a launcher on the left of your screen. If it appears that the size of the icons on the launcher is too big, you can adjust it to a smaller size you like.

1. Click the Control Gear and select "System Settings".
2. Click "Appearance" under "Personal".
3. Under the Look tab, drag the slider of "Launcher Icon Size" to the left.

In the same context, moving the slider to the right gets you larger icons on the Launcher.
