How to Change Windows 11 Clock Font, Size, and Color

If you’re looking to personalize the clock font in Windows 11, you may find that the operating system itself offers limited options. The built-in Settings app does not provide any features to modify the taskbar clock’s typeface, size, or color. To achieve this customization, a third-party tool called Windhawk is required, along with its free Taskbar Clock Customization mod. During testing on Windows 11 Pro version 25H2, changing the clock’s font family, size, and weight was successful. The mod also includes settings for italic text and custom colors, which are clearly marked in the following sections based on personal testing and mod documentation.

Why Windows 11 has no built-in clock font setting

While Microsoft provides some clock options in Windows 11, they do not extend to aesthetic changes. Within Settings > Time & language > Date & time, users can adjust the time zone and choose between 12-hour or 24-hour formats. Recent builds even allow for the display of seconds in the system tray clock.

The font used is derived from the system UI font, Segoe UI Variable, with the taskbar’s text color adapting to the selected light or dark mode. Unfortunately, there is no option for individual element overrides.

Windhawk circumvents this limitation by injecting small code modules, or mods, into running processes. The clock mod specifically hooks into explorer.exe to restyle the clock text after the taskbar renders it. As a community-driven project, it lacks official support from Microsoft, meaning that a Windows update could potentially disrupt its functionality.

Requirements and a quick safety note

According to the mod’s documentation, the following requirements must be met:

• Operating system: Windows 10 64-bit or Windows 11. The font and color styling options specifically require Windows 11 version 22H2 or newer.
• Windhawk: Must be installed from windhawk.net and running in the background. Note that mods cease to function when Windhawk is not active.
• Internet access: Required for the initial mod load, as Windhawk downloads Microsoft’s public debug symbols to locate taskbar code. A firewall blocking this access can hinder the mod’s performance.

Testing was conducted on a Windows 11 Pro 25H2 system, and results may vary on other builds, particularly Insider or preview releases.

On safety: Windhawk is open-source, with the clock mod’s code available on GitHub under GPL v3, developed by m417z. However, code injection may trigger alerts from some antivirus software. Windhawk’s installation screen advises caution with unverified mods, so it is wise to create a restore point beforehand. Removing the mod is straightforward, as will be detailed later.

Step 1: Install Windhawk from the official website

1. Visit windhawk.net in your browser and download the installer, avoiding third-party download mirrors.
2. Run the setup file and accept the UAC prompt.
3. Select a standard installation; while a portable version is available, a standard install is more convenient for startup.
4. Launch Windhawk once the setup is complete. Its icon will appear in the system tray, and the application must remain active for mods to function.

Step 2: Install the Taskbar Clock Customization mod

1. In Windhawk, click on Browse for Mods or the Explore button at the top of the window.
2. Search for Taskbar Clock Customization and select Details on the mod created by m417z.
3. Click Install. Windhawk will display a warning regarding potential risks; confirm by selecting Accept risk and install.
4. Wait a few moments as Windhawk compiles and loads the mod. The taskbar clock should update immediately.

Don’t panic when the clock looks different

The mod’s default settings modify more than just the font. Initially, the top line displays the date and time with seconds, while the bottom line shows a news headline sourced from a New York Times RSS feed. For those primarily interested in changing the font, resetting the layout is advisable.

On the Windhawk home page, locate the installed “Taskbar Clock Customization” mod, click the Details button, and navigate to the Settings tab. Adjust the following fields:

• Top line: %time%
• Bottom line: %date%
• Show seconds: disable if seconds are not desired.
• Time format and Date format: clear these fields to revert to Windows defaults. The default time format includes seconds.

To restore the default Windows value, input a single hyphen (-) in either the Top line or Bottom line field. Remember to click Save settings after each change.

How to change Windows 11 clock font settings in the mod

Within the Settings tab, scroll down to two sections: Top line style (Windows 11 version 22H2 and newer) and Bottom line style (Windows 11 version 22H2 and newer). Each section offers distinct font options, allowing for separate styling of the time and date.

Change the font family

Specify the exact name of an installed font in the Font family field. Ensure it matches the name recognized by Windows, which can be verified under Settings > Personalization > Fonts. Fonts included with Windows, such as Consolas or Bahnschrift, are reliable choices. The mod provides a link to Microsoft’s Windows 11 font list for reference.

On my 25H2 system, I set the font family to “Cambria Math,” and the clock updated immediately upon saving. Leaving the field blank will revert to the system font. Simply type or copy the font name and click the Save button to apply changes. Additionally, you can adjust the font weight and style for improved visibility if desired.

Change the clock font size

The Font size field accepts numerical values, with zero representing the default size. I experimented with sizes and settled on [19] for my display. Be mindful that excessively large sizes may be clipped, as the taskbar does not adjust its height to accommodate larger text. If this occurs, consider reducing the size or adjusting the Line spacing near the top of the settings.

Change the font weight

The Font weight dropdown ranges from Thin and Extra Light to Normal, Semi Bold, and up to Black and Extra Black. I tested various weights, and the changes were successfully applied upon saving. Note that not all fonts support every weight; a font lacking a Thin variant will render at the nearest available weight.

Change the font style (italic)

The Font style options include Default, Normal, Oblique, and Italic. There is also a Font stretch feature for condensed or expanded text, though the mod notes that this may only work with select fonts.

Change the clock color

The Text color field accepts color names like Red or White, or hex codes. Use #RRGGBB for solid colors, or #AARRGGBB to incorporate transparency, where the first two digits define opacity. For instance, #00FF00 represents pure green, while #CC00FF00 indicates the same green with slight transparency. Testing confirmed that colors like Red functioned correctly.

Choose a color that contrasts well with your taskbar. A dark color may appear fine in light mode but become unreadable in dark mode, as the mod’s color settings override the theme.

Extra options: alignment and spacing

Each style group also includes settings for Text alignment, Character spacing (which can be positive or negative), and Line height. These options are useful for fine-tuning the appearance of wider fonts that may crowd the tray icons.

How to style the time and date separately

The mod does not differentiate between “time” and “date” in its styling; instead, it styles the top line and bottom line. To achieve separate styling for each, follow these steps:

1. Set the Top line to %time% and the Bottom line to %date%.
2. In the Top line style, configure the font, size, weight, and color for the time.
3. In the Bottom line style, apply a different appearance for the date, such as a smaller size or lighter weight.
4. Click Save settings.

The bottom line will only be visible if the taskbar is sufficiently tall, as indicated in the mod’s settings description. Large font sizes may push it out of view. Each style group also features a Hidden toggle if you prefer to conceal one line entirely.

Troubleshooting

Settings don’t apply

If changes do not take effect, first ensure that you clicked Save settings. Unsaved modifications will not reach the taskbar. Verify that the font name in the Font family field matches an installed font exactly; typos often result in the clock reverting to the system font.

If no changes occur, consider disabling and re-enabling the mod, or restarting Windhawk from its tray icon. Additionally, confirm that you are using Windows 11 version 22H2 or newer, as style options are not applicable to older builds.

The taskbar glitches or the clock looks cut off

Oversized fonts and excessive spacing can lead to crowding in the clock area. To remedy this, reduce the font size, adjust Character spacing, or set Clock max width (Windows 11 only) to a fixed value. If the taskbar continues to misbehave, disable the mod and restart Windows Explorer from Task Manager if the issue persists.

A Windows update broke the mod

This situation can occur. Users have reported that updates, such as the KB5095093 preview update in June 2026, caused the Taskbar Clock Customization to cease functioning. Windhawk relies on Microsoft’s debug symbols, which may take a day or two to be published following a new build.

Windhawk’s troubleshooting guide suggests the following steps:

1. Update Windhawk and the mod to their latest versions.
2. Allow a day or two for very recent updates, then disable and re-enable the mod.
3. Check that your firewall is not blocking Windhawk’s symbol downloads.
4. If issues persist, access the mod’s Advanced tab, set Debug logging to Detailed debug logs, click Show log output, and enable the mod. An HTTPSTATUSNOTFOUND error indicates that symbols are not yet published; ERRORINTERNETCANNOTCONNECT suggests a network or firewall issue.
5. After troubleshooting, revert Debug logging back to None and report ongoing problems on the windhawk-mods issue tracker, including the log.

Additionally, antivirus software may block Windhawk’s code injection. The guide recommends temporarily disabling the antivirus for testing and adding an exclusion if it is determined to be the cause.

How to disable the mod and restore the default clock

To temporarily revert to the original clock:

1. Open Windhawk.
2. Locate Taskbar Clock Customization among your installed mods and click Disable.

The clock will revert to the standard Windows 11 appearance, while your settings will remain saved for future use. Click Enable to reinstate them.

To permanently remove the mod, access its details and select Remove, then confirm. If no mods are in use, Windhawk can be uninstalled via Settings > Apps > Installed apps.
