How to change the size of the clock on the lock screen Xiaomi: all ways for MIUI

Xiaomi's lock screen is the first thing you see when you turn on your smartphone, and the watch plays a key role in how you experience the interface. For some users, the standard digit size seems too small, for others it is too bulky. Unfortunately, in the latest versions of MIUI (starting with the 12th), the manufacturer has removed the direct slider adjustment, leaving only a few fixed styles. But that doesn't mean that there is no possibility at all.

In this article, we’ll look at all the current ways to change the size of the watches on the lock screen of Xiaomi, Redmi and POCO – from official settings to hidden features and workarounds. You’ll learn how to adapt the display to your preferences, even if your model does not support flexible settings out of the box.

Why does MIUI not have a slider to change the size of the watch?

Before MIUI 11, users could freely adjust the size of the clock on the lock screen with a slider in the settings, but in MIUI 12 and later, this feature was eliminated.

• 🎨 Design unification: Xiaomi aims to bring uniformity to the interface across all devices, limiting customization options.
• 📱 Adaptability for different screens: Automatic adjustment to resolution (from the HD+ before 2K) Simplifies support for developers.
• ⚙️ Simplifying settings: Reducing the number of settings reduces the likelihood of user errors (for example, when the clock becomes unreadable due to excessive reduction in the number of parameters).

However, even without the slider, there are legal and non-obvious ways to influence the size of the displayed time.

Method 1: Use of built-in watch styles (official method)

The safest and most recommended way for Xiaomi is to choose from predefined styles, which differ not only in design, but also in font size.

1. Open the Settings → Lock screen.
2. Slip on the item "Clock Style" (or "Clock screen" in older versions).
3. Scroll through the options available. Pay attention to the styles marked: 🔍 "Large or Large – increase the size of the numbers by 20-30%. 📱 "Minimalist – usually reduces the font. 🎨 "Digital or Analog – may have different heights depending on the model.

Apply

If neither style suits you, move on to the following methods, and note that on some devices (such as the POCO F5 or Redmi Note 12), the style list may be limited due to firmware features.

Method 2: Customization through themes (alternative legal method)

Few people know, but the size of the watch may depend on the chosen theme. Some themes from the official Xiaomi Themes store offer unique styles with custom fonts.

1. Go to Settings → Theme (or open the Themes app from the desktop).
2. In the Lock Screen section, select the Watch category.
3. Look at the available topics. Pay attention to the preview, and you can see the approximate size ratio.
4. Download and apply your theme. Some paid themes (like Minimal Clock Pro or Big Digits) specialize in big watches.

Important: After changing the theme, not only can the size of the watch change, but the font, color scheme, and the location of the widgets, and if you need to save the rest of the lock screen, this method may not work.

Method 3: Editing system files (for advanced users)

This method requires an unlocked bootloader and root rights, and is only suitable for power users. It allows you to manually change the settings of the display of the watch by editing system files. Incorrect actions can lead to a failure of the lock screen or complete failure of the device.

Instructions for MIUI 13/14:

1. Install a file manager with root support (such as Root Explorer or Solid Explorer).
2. Cross the path: /system/media/theme/default/lockscreen/ or (for certain models): /system/priv-app/MiuiSystemUI/MiuiSystemUI.apk/res/drawable-xxxhdpi/
3. Find files with type names clock_style_*.xml or lockscreen_clock_layout.xml.
4. Open the file in the text editor and find the parameters that determine the font size (e.g., android:textSize="48sp").
5. Change the value to the desired one (for example, 60sp to zoom in) and save the file.
6. Reset the device.

⚠️ Warning: Before editing system files, be sure to back up the original data. Changes may reset after the update MIUI.

If the watch has disappeared or is not displayed correctly after the changes, return the original values or restore the file from the backup.

💡

Before editing system files, check the owner and access rights. Often you need to set the rights 644 (rw-r--r--) and the owner of root:root.

Method 4: Applications for customization (without root)

For users who do not want to risk the stability of the system, there are third-party applications that allow you to change the appearance of the lock screen.

• 📱 Always On Display (AOD): The app creates a layer of customizable clock over the standard lock screen, supports size, font and color adjustment, and minus increased battery consumption.
• ⏰ Lock Screen Customizer: Allows you to change the style of watches, add widgets and even animations. Requires permission to display over other windows.
• 🎨 KLWP Live Wallpaper: A hard to set up yet flexible tool for full customization.You can create a unique lock screen with any size watch.

Typically, these apps don’t require root rights, but they may conflict with system updates or antiviruses. Before installing, check user reviews of your Xiaomi model.

⚠️ Note: Some lock screen customization apps may collect data about your activity, only from trusted sources (Google Play, Xiaomi official website).

Method 5: Use ADB-Teams (for technically savvy teams)

If you have experience with ADB (Android Debug Bridge), you can try changing the size of your watch through commands, which doesn't require root, but you need activated USB debugging.

Instructions:

1. Connect your smartphone to your PC and start the command line (or Terminal on Mac/Linux).
2. Enter the command to check the connection: Adb devices Make sure your device appears in the list.
3. Execute the command to change the size of the watch (example to zoom in): adb shell settings put system lock_screen_clock_size 2.0 Where 2.0 — scaling-rate (1.0 — standard-size, 1.5 — rise 50%).
4. Reset the device.

Not all versions of MIUI support this command. If nothing changes after execution, then your firmware will block such interference, in which case only editing system files (Method 3) will help.

💡

ADB-Teams only work on firmware with support for system settings via settings put. On some Xiaomi devices, this method can be disabled by the manufacturer.

Frequent problems and their solutions

When changing the size of the watch, users often encounter common errors, and consider the most common and ways to fix them:

• ❌ Watch disappears after style change: Return the standard theme or reset lock screen settings in Settings → System system → Resetting settings → Reset the lock screen settings.
• ⚙️ No changes to system files: Check file access permissions (should be 644) and owner (should be root).
• 🔋 Increased battery consumption after installing a third-party application: Disable the background activity of the application in Settings → Annexes → Permits → Auto-start.
• 📱 The clock is straying after the update MIUI: Updates often reset customization. Before the update, backup the modified files.

If none of the methods worked, your Xiaomi model may have some limitations on the manufacturer’s part, so you can either accept the current size or consider alternative launchers that support lock screen customization (e.g. Nova Launcher + Sesame Shortcuts).
