This article describes steps to change the size of icons on the Dock or launcher in Ubuntu Linux.
By default, the Dock (or apps launcher) in Ubuntu Linux has application icons that are left-aligned or docked on the left side of the screen. However, you can move the Dock to the bottom of the right of your screen.
You can also change the size of the Dock in Ubuntu Linux. This is because the application icons on the Dock are proportional to the size of the Dock. Therefore, if you increase the icon size, you also increase the size of the Dock.
So, if you have a small screen and want to create a bigger work area, you can decrease the size of the icons, which also decreases the size of the Dock.
On the other hand, if the icons are too small, you can increase them so they can be seen clearly.
Below is how to change the size of application icons on the Dock in Ubuntu Linux.
