The default Windows 11 Taskbar size may not suit your preferences or screen resolution. Adjusting the Taskbar size can expand the screen space, making it easier to see the icons. Windows 11 allows users to change the Taskbar size through several methods according to the instructions below.
Resize Windows 11 Taskbar via Registry Editor
Step 1:
Press the Windows + R key combination to open Notepad and then enter the keyword regedit in the interface.

Step 2:
In the next interface, you navigate to the path below.
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced

Step 3:
Right-click on the blank space in the right pane, select New then click DWORD (32-bit) Value .

We will name this new value TaskbarSi.

Step 4:
Double-click the newly created TaskbarSi value and set its data to one of the following values:
- 0 for small taskbar icons.
- 1 for medium sized taskbar icons (default).
- 2 for large taskbar icons.
Click OK and restart your computer for the changes to take effect.

Resize Windows 11 Taskbar via resolution
Step 1:
Right-click anywhere on the desktop and select Display settings from the context menu.

Step 2:
In this interface under Scale & layout you will see options to change the percentage. Reducing the percentage (for example, from 125% to 100%) will shrink the icons on the Windows 11 Taskbar and overall interface elements, giving you more screen space. Conversely, increasing the scale will enlarge the icons on the taskbar and the interface.

Additionally, you can adjust your screen resolution to indirectly affect the Taskbar size. Increasing the resolution makes the elements smaller, while decreasing the resolution makes them larger.
