How to make bold font on Xiaomi: all the ways for MIUI 12-15

Are you tired of squinting while trying to see the fine text on the Xiaomi screen? Or just want to add style to the interface, making the font more expressive? The bold text on the brand’s smartphones is included in literally several taps — but not all users know where to look for this setting. Depending on the version of MIUI (12 to 15) and the device model (Redmi Note 12, POCO X5, Xiaomi 13T, etc.), the ways may vary.

In this article, we'll look at all the current methods, from standard settings to hidden features and third-party themes, learn how to make text bolder in menus, messages, browsers and even in individual applications, and explain why some devices can block the option and how to get around it. You don't need to install additional launchers or root rights: most solutions work out of the box.

Method 1: Standard setting of bold font in MIUI

The easiest method is to use the built-in option in the system settings. It works on most devices with MIUI 12-15, including Redmi, POCO and Xiaomi’s flagship series, with the exception of some budget models with stripped-down firmware (for example, the Redmi A1).

To activate bold:

1. Open the settings (the gear icon on the desktop).
2. Go to the Screen section (or Display on some versions).
3. Select font style or text and scale.
4. Activate the slider Fat (or Bold text in English localization).
5. Confirm the changes – the device will restart.

After the reboot, all system text (menu, notifications, keyboard) will become bolder, and on some devices this method works only for system fonts, but does not affect third-party applications (for example, Telegram or Chrome).

Update MIUI to the latest version (in Settings → About Phone → System Update)

Make sure you don’t have a third-party launcher installed (Nova, Apex, etc.)

Check if the power saving mode is activated (can block font changes)

Method 2: Using design themes

If your MIUI version doesn’t have a separate bold option, you can get around this restriction with the themes. Many custom themes already include modified fonts, including bold variants. This method is suitable for devices with MIUI 13/14, where standard settings are limited.

Instructions for installing theme with bold font:

• 🎨 Open the Themes app (brush icon on desktop).
• 🔍 In the search bar, type in the queries: "bold font", "bold font" or "thick text".
• 📥 Choose your favorite theme (pay attention to the rating and number of downloads).
• 🖼️ Click Apply and Confirm the Installation.

Method 3: Hidden settings for power users

If the first two methods didn’t work, you can try to activate bold through the hidden developer settings or ADB-This method requires a little more effort, but often helps on devices with stripped firmware (for example, Redmi Go or the Redmi Go). POCO C-series).

First, turn on the developer mode:

1. Go to Settings. → The phone.
2. 7 times to tap on the item version MIUI.
3. Return to the main settings menu and a new section for developers will appear.

Now you can try two options:

A safer option is to use MIUI Hidden Settings (available on Google Play), which allows you to change font settings without ADB:

• 📱 Install and open the application.
• 🔧 Go to the Font Settings section.
• 📏 Set the Font Weight setting to Bold or Extra Bold.
• 🔄 Save the changes and restart the phone.

⚠️ Attention: Changing hidden settings can lead to unstable interface operation. If after manipulations there are artifacts of text (for example, letter clipping), reset the font settings to the standard ones.

Method 4: Bold in individual applications

Sometimes users only need to bold text in specific programs, such as WhatsApp, Telegram or browser, and fortunately, many popular apps support this feature regardless of system settings.

How to include bold text in popular applications:

Social media (Vkontakte, Instagram) usually requires third-party apps like Bold Keyboard or Fancy Text Generator, which convert text to bold before inserting.

💡

If the app doesn’t have a built-in bold text option, try zooming in on the special features settings (Settings → Special Options → Font size) that won’t make the text bold, but will improve readability.

Why can't bold print be included?

Not all Xiaomi devices have the bold option working correctly, here are the main reasons and solutions:

• 📵 Cut firmware: On budget models (Redmi) A1, POCO C31) Often there is no option. Solution: use themes or ADB.
• 🔄 An outdated version MIUI: On versions below MIUI 12 bold font may not be supported. Update the system in Settings → Update of the PO.
• 🔒 Manufacturer Block: On some devices for the Chinese market (Xiaomi for the Chinese market) CN-region) option disabled. Solution: run the global version MIUI.
• 🛠️ Launcher conflict: Third-party shells (Nova, Apex) can override the system settings of the font.

If none of the methods worked, check:

1. Is the Power Saving mode activated (can block interface changes)
2. Are there any restrictions in Settings → Battery → Background Limitation for system applications?
3. Is the font system library damaged (resetting settings in Settings → Additional → Resetting settings will help).

💡

On devices with MediaTek (Helio G-series) processors, bold font problems are more common than on Snapdragon, which is due to optimizing MIUI for different hardware.

How do you get back the standard font?

If you dislike the bold text or cause problems with display, it is simple to return the standard settings:

1. For system font: go to Settings → Screen → Font style and deactivate the option Fat.
2. For design themes: Open the Themes app, select Standard or Default and apply it.
3. For ADB-Enter the command adb shell settings delete system font_weight and reboot the device.

If the text is not displayed correctly after disabling bold (for example, some letters have become squares), follow the following steps:

• 🔄 Reset the device.
• 🧹 Clear the cache in Settings → Annexes → Application management → System applications → Cash.
• 📥 Update fonts through Settings → Additionally. → Update fonts (if the item is available).
