How To Adjust the Size of the Windows 11 Taskbar

📅
🕑 4 minutes de lecture

Windows 11’s taskbar and Start menu have definitely changed things up — less customizable, more locked down. One of those annoyances? The fact that you can’t just drag to resize the taskbar like in Windows 10. Yeah, it’s kind of weird, but you’re not totally stuck. Sure, the default size is a little larger than in Windows 10, but if you liked a smaller, more compact taskbar, there’s a workaround. It involves some Registry edits, which sounds scarier than it is. Just make sure to create a restore point first, because Windows Registry can be a beast if you mess up. But honestly, it’s pretty safe if you’re careful. This guide will show how to tweak the Registry to make the taskbar a bit smaller or bigger than the default medium size. When done right, your taskbar icons will resize accordingly, and you’ll get something that feels more natural. Expect a more tailored look — no more unnecessarily huge or tiny icons. Just someone who’s seen this issue a thousand times, trying to make Windows look just right without waiting for some official update or hack that may or may not ever come. If you want more control than what Windows gives you out of the box, this is probably your best bet. Let’s dive into how to get there without breaking anything.

How to change the taskbar size in Windows 11

Make a backup or create a system restore point first

Before diving into registry edits, it’s always good to create a restore point. Just in case something goes sideways, you can roll back. To do that, type System Restore in the search bar, hit Create a restore point, and follow the prompts. It’s a quick safety net, especially when poking around the registry.

Open the Registry Editor

  • Press Win + R, type regedit and hit Enter. This opens the Registry Editor.
  • If you see a UAC prompt, click Yes. No need to panic — just be cautious when editing.

This is where the magic happens, but also where you can break things if you’re not careful.

Navigate to the right registry path

  • In the Registry Editor, go to: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced

Trust me, this is where Windows stores a lot of the display tweaks. If you don’t see the Advanced key, double-check the path. Sometimes, Windows 11 is weird about things, but this path usually works.

Create or modify the TaskbarSi DWORD value

  • Right-click on an empty space on the right side of the window, choose New, then DWORD (32-bit) Value.
  • Name it TaskbarSi. If it already exists, just skip this step.

Why? Because this tiny registry key controls the taskbar size in three levels: small, medium, and large. It’s kind of weird that Windows doesn’t make this easier, but hey, here we are.

Set the size value

  • Double-click on TaskbarSi. You’ll see a box to enter a value.
  • Set the value data to:
    • 0 to make the taskbar smaller (icons smaller, more space-efficient).
    • 1 for the default medium size (the normal size you see now).
    • 2 if you want a larger taskbar with bigger icons.

After changing it, hit OK.

Refresh or restart Explorer to see changes

  • Close the Registry Editor.
  • Now, you need to restart Explorer to apply the changes. You can do that via Task Manager:
    • Press Ctrl + Shift + Esc to open Task Manager.
    • Find Windows Explorer in the list.
    • Right-click it and choose Restart.

Sometimes, if you notice it didn’t work right away, a reboot can help. On some setups, Explorer might need a full restart or sign out/in to fully refresh the taskbar size.

And that’s it—kind of hacky, but hey, it works. On some machines, the changes take immediately, on others, a quick reboot is needed. Also, keep in mind this tweak is kinda fragile if Microsoft sneaks in an update that resets or blocks registry changes—so, save the restore point before you mess with stuff.

Summary

  • Backup your registry first, for safety.
  • Use regedit to navigate to HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced.
  • Create or edit the TaskbarSi DWORD value.
  • Set the value to 0 (small), 1 (default), or 2 (large).
  • Restart Explorer or reboot to see the changes.

Wrap-up

This isn’t the prettiest workaround, but it’s been reliable enough to customize the taskbar size without waiting on Microsoft to add a UI tweak. Just know, Windows 11’s locked-down nature means you’re kind of fighting a bit with it. If it doesn’t work on your machine, maybe try rebooting, or check if any updates changed stuff. Fingers crossed this helps someone get a tiny bit closer to that perfect setup.
