Changing the dock icon size in Ubuntu Linux lets you resize the app shortcuts on your screen to fit your exact setup. The dock, also called the launcher or Dash, sits on the side or bottom of your screen to hold your favorite apps.

You can adjust these icons down to a tiny 16 pixels or up to a massive 64 pixels depending on your screen size and what feels comfortable. Ubuntu 23.10 and newer versions include this setting right inside the main desktop appearance menu so you do not need to install extra tools.

⚡ Quick Answer

Navigate to Settings, then Appearance. Use the Icon size slider under Dock to adjust the size of the dock icons and the dock itself.

How to change the size of the Dock or launcher in Ubuntu Linux

Ubuntu Dock icon size can be changed directly from the desktop settings menu without installing any extra tools. Open Settings , select the Appearance tab, and find the panel size slider to make your launcher icons larger or smaller. Moving this slider changes both the icon dimensions and the overall width of the dock at the same time.

Adjusting the dock icons changes the size of both the icons and the Dock itself.

Here’s how to do that in Ubuntu.

Open System Settings from the Activities overview by typing Settings.
