To customize your Windows 11 taskbar size, open Settings > Personalization > Taskbar > Taskbar behaviors and select Show smaller taskbar buttons. Choose Always for a smaller taskbar, When taskbar is full for automatic shrinking, or Never to keep normal-size buttons; availability depends on your Windows build and rollout.
Windows 11 has two different size controls that are often confused. Taskbar button scaling targets the taskbar, while Display scaling enlarges text, apps, icons, and other interface elements across the entire screen.

Key takeaways
- Show smaller taskbar buttons is the Windows 11 setting for compact taskbar icons, with Always, When taskbar is full, and Never options.
- Always keeps the taskbar in the smaller-icon, shorter-taskbar state on supported builds.
- Never stops Windows from automatically shrinking taskbar buttons when the taskbar becomes crowded.
- Display scaling can make taskbar icons larger, but it also enlarges text, apps, and other interface elements across the display.
- The taskbar-size setting is rolling out by Windows build, Insider channel, region, and staged enablement, so it may not appear on every Windows 11 PC.
How do you customize your Windows 11 taskbar size?
Windows 11 users can customize taskbar size by opening Settings > Personalization > Taskbar > Taskbar behaviors and changing Show smaller taskbar buttons. Choose Always for a smaller taskbar, When taskbar is full for automatic shrinking only when space is limited, or Never to keep normal-size buttons. The setting is available only on supported or newer Windows 11 builds.
Microsoft’s newer compact-taskbar experience changes taskbar icon and button size and, in that experience, taskbar height as well. The feature does not require a separate taskbar-height slider. Microsoft describes the rollout in its Windows Insider taskbar announcement, while earlier preview documentation also describes the three choices.
#1 Best Overall
Which Windows 11 taskbar size option should you choose?
The correct choice depends on whether you want a permanently compact taskbar, protection against crowding, or the normal button size.
| Setting | What Windows does | Best for | Trade-off |
|---|---|---|---|
| Always | Keeps taskbar buttons and icons smaller and reduces taskbar height in the compact experience. | Users who want more usable space on a small display. | Icons and buttons are smaller all the time. |
| When taskbar is full | Uses normal-size buttons until available taskbar space becomes limited, then shrinks the icons. | Users who want normal icons without overflow when many apps are open. | The taskbar can change size as space becomes constrained. |
| Never | Prevents the automatic smaller-button behavior and keeps the normal icon size. | Users whose icons become tiny when they open or pin more applications. | More open windows or pinned apps may make the taskbar crowded. |
Microsoft’s description of the three choices is available in the documentation for Windows 11 Insider Preview Build 27898. The wording and availability can change as Microsoft moves the experience through preview and staged releases.
How do you make the Windows 11 taskbar smaller?
Choose Always under Show smaller taskbar buttons. On supported builds, Windows immediately switches to smaller taskbar icons and the shorter compact-taskbar state without requiring a sign-out or restart.

One-click scans. No signup required.
- Press Windows + I to open Settings.
- Select Personalization.
- Select Taskbar.
- Expand Taskbar behaviors.
- Find Show smaller taskbar buttons.
- Select Always.
- Look at the taskbar to confirm that the icons and taskbar height have changed.
If the taskbar does not change immediately, verify that the option was actually applied, then restart Windows Explorer or restart the computer as a troubleshooting step. Microsoft says the newer compact-taskbar experience itself does not require a restart or sign-out, so a restart is a recovery step rather than a normal requirement.
How do you stop Windows 11 from shrinking taskbar icons when the taskbar is full?
Set Show smaller taskbar buttons to Never. This is the first setting to try when taskbar icons suddenly become tiny after opening more applications or pinning additional programs.
Windows may shrink taskbar icons when available space is limited if the setting is configured to allow automatic behavior. Select Never, close unused windows, and remove unnecessary pinned applications if the taskbar remains crowded. Microsoft documents the crowded-taskbar behavior in its Insider Preview Build 27898 notes.
How do you let Windows shrink taskbar icons only when necessary?
Select When taskbar is full if you want normal-size taskbar buttons in ordinary use but accept smaller icons when open windows or pinned applications use the available space.
This option is a compromise between Always and Never. It preserves the normal taskbar appearance until Windows needs additional room, but the taskbar can become smaller when the available space is constrained.
Rank #2
What should you do if “Show smaller taskbar buttons” is missing?
If Show smaller taskbar buttons is absent, the feature may not have reached the Windows build, channel, region, or staged rollout installed on the computer. Missing the setting does not necessarily mean that you overlooked it.
- Open Settings > Personalization > Taskbar.
- Expand Taskbar behaviors and check carefully for the setting.
- Press Windows + R, type
winver, and press Enter. - Record the Windows edition, version, and OS build shown in the About Windows window.
- Check whether the computer is running a preview or Windows Insider build.
- Install available Windows updates and check the Taskbar behaviors page again.
Microsoft described taskbar icon scaling in Windows 11 Release Preview documentation and separately described a shorter-taskbar experience rolling out to an Experimental Insider channel. The Release Preview announcement and the later Insider announcement do not establish that every retail Windows 11 installation has the control. Availability should therefore be verified on the individual computer rather than inferred from the Windows 11 edition alone.
How can you make the taskbar larger when the setting is unavailable?
Use Windows display scaling if the goal is to make taskbar icons and other interface elements easier to see. Open Settings > System > Display, find Scale & layout, and choose a higher percentage.

- Under Scale & layout, open Scale.
- Choose a higher available scale percentage.
- Check the taskbar, text, applications, and other Windows interface elements.
- Keep the new scale only if the whole desktop remains comfortable to use.
Display scaling is not an independent taskbar-size control. Microsoft-hosted guidance explains that display scaling enlarges taskbar icons along with text and other interface elements across Windows. See the Microsoft Q&A discussion about taskbar icons that are too small and the related Microsoft Q&A guidance on increasing taskbar icon size.
| Method | Changes only the taskbar? | Can make the taskbar smaller? | Can make it larger than normal? | Availability |
|---|---|---|---|---|
| Show smaller taskbar buttons | Primarily targets taskbar buttons and icons. | Yes, with Always. | Microsoft’s current documentation does not establish a corresponding larger-than-normal mode. | Supported or newer builds where Microsoft has enabled the feature. |
| Display scaling | No; it affects text, apps, icons, and other display content. | Not as a taskbar-only adjustment. | Yes, indirectly, by enlarging the whole interface. | Built into Windows 11. |
| Registry edits or third-party tools | Potentially, depending on the tool or edit. | May be possible but is not a current universal supported method. | May be possible but compatibility varies. | Unsupported or dependent on external software. |
Does Windows 11 have a taskbar-height slider?
Windows 11 does not provide a documented general user-facing slider for choosing arbitrary small, medium, or large taskbar heights. The supported native experience is narrower: the newer button-scaling control provides a compact mode or conditional shrinking, while display scaling affects the entire interface.
Microsoft’s official Windows taskbar customization documentation covers features such as alignment, pinned applications, Search, Widgets, Task View, system-tray visibility, and automatic hiding. Microsoft’s Windows 11 settings reference lists documented taskbar-related settings, but it does not document a supported registry value that provides arbitrary taskbar dimensions.

You should not treat the old TaskbarSi registry edit as a guaranteed or current Windows 11 solution. An older Microsoft Q&A community answer describes a TaskbarSi value under HKCUSoftwareMicrosoftWindowsCurrentVersionExplorerAdvanced, but the workaround is not equivalent to current Microsoft product documentation, and reports in the same discussion describe failures and visual problems.

Rank #3
What should you do if the taskbar stays small after choosing Never?
If the taskbar remains small after selecting Never, check the Windows build and whether the computer is running an Insider or preview release before assuming that the setting failed.
- Open Taskbar behaviors again and confirm that Never is still selected.
- Run
winverand note the version and build. - Install available Windows updates.
- Restart Windows Explorer from Task Manager, or restart the PC.
- Recheck the taskbar after Windows has loaded.
Microsoft documented an Insider-build issue in which taskbar icons could appear small even when the setting was configured as Never. The Windows Insider Build 26120.4161 announcement supports treating this as a possible preview-build problem rather than automatically blaming the user’s configuration. None of these troubleshooting steps is guaranteed to correct every preview-build issue.

Frequently Asked Questions
How do I make the taskbar smaller in Windows 11?
Windows 11 users can make the taskbar smaller by opening Settings > Personalization > Taskbar > Taskbar behaviors and selecting Always under Show smaller taskbar buttons. The option is available only on supported or newer builds where Microsoft has enabled the feature.
How do I stop Windows 11 taskbar icons from shrinking?
Choose Never under Show smaller taskbar buttons to stop Windows from shrinking taskbar icons when the taskbar is crowded. If the setting is unavailable, the computer may not have received the feature yet.
Can I make the Windows 11 taskbar larger?
Windows 11 does not currently document a general taskbar-only control for making the taskbar larger than its normal size. Display scaling can enlarge the taskbar, but it also enlarges text, apps, icons, and other interface elements.
Why is Show smaller taskbar buttons missing in Windows 11?
A missing Show smaller taskbar buttons option usually reflects differences in Windows build, Insider channel, region, or staged rollout. Run winver with Windows + R to record the installed version and build, then check for updates.
The Bottom Line
For a smaller Windows 11 taskbar, choose Settings > Personalization > Taskbar > Taskbar behaviors > Show smaller taskbar buttons > Always. Choose Never to stop automatic shrinking when the taskbar is crowded. If the setting is missing, check winver; display scaling is the built-in fallback, but it enlarges the entire interface rather than only the taskbar.
