How to reduce font on Xiaomi phone: all the ways for MIUI 12, 13 and 14

The font size on Xiaomi smartphones is often a source of discomfort: too large letters take up half the screen, and small text is difficult to see without glasses. In this article, we will examine all the official and hidden ways to reduce the font – from basic MIUI settings to editing configuration files for advanced users.

It is important to understand that changing the size of text affects not only the ease of reading, but also the density of information on the screen. For example, reducing the font by 2 points can add 1-2 lines in messengers or browsers. However, some applications (for example, TikTok or Instagram) ignore the system settings - they will require separate solutions, which we will also consider.

1. Standard font size setting in MIUI

The easiest way is to use built-in shell tools, which works on all Xiaomi devices with MIUI 12 and later, including POCO and Black Shark. The interface may vary slightly depending on the firmware version, but the algorithm of actions remains the same.

To change the font size:

1. Open the Settings app (cog icon).
2. Go to the Screen section (or the Display on some models).
3. Select the text size (sometimes hidden under the Supplement).
4. Move the slider left to zoom in or right to zoom in. Available values range from Small (80%) to Very Large (130%).
5. Click Ready or Apply to save the changes.

Limitations of the method:

• 📱 Minimum font size in MIUI — 80 percent of the standard. If you want to make the text smaller, you need to use alternative methods.
• 🔄 The changes apply to all system applications, but some third-party programs (such as WhatsApp or Telegram) may ignore the settings.
• 🔍 Some models (e.g. Xiaomi Mi) A3 With pure Android One, the path to settings is different: Settings → System system → Language and input → Type size.

2. Change the screen size (Display Size)

If the font reduction doesn't work, try changing the pixel density (DPI) that determines how many interface elements are placed on the screen, and reducing the DPI automatically reduces the size of the font, icons, and other elements.

Instructions for MIUI 13/14:

1. Open the Settings → Screen.
2. Select the screen size (or display size).
3. Move the slider to the left. Available values: Compact (maximum decrease, ~400 DPI) Standard (~440 DPI) Large (~480 DPI)

Confirm the change. The phone will reboot.

Important: on models with AMOLED-screens (for example, Xiaomi 12 Pro or Redmi) K50 Pro) excessive reduction DPI It can cause blurring of text due to subpixel rendering. If the letters become fuzzy, return the standard settings.

⚠️ Attention: on devices with screen resolution below FHD+ (Like Redmi. 9A s HD+) reduction DPI below 400 can make text unreadable. Before changing, check your display resolution in Settings → The phone. → Screen characteristics.

3.Using the Developer Mode for Fine Customization

For users who need non-standard DPI values (e.g., 360 or 480), the method is available through Developer Mode, which will allow you to set any value in the range of 120-640 DPI.

How to turn on the developer mode and change the DPI:

1. Go to Settings. → The phone.
2. Find the MIUI version and tap it 7 times in a row. You will be notified of becoming a developer!
3. Return to the main Settings menu and open a new section → For developers.
4. Find the minimum width (dp) (or smallest width) option.
5. Enter a value from 320 (maximum decrease) to 530 (magnification). Recommended value for compact display: 360-400.
6. Reboot the phone.

4. Reduce font in individual applications

Some programs (e.g. YouTube, VK or Yandex Browser) have their own font settings that are independent of system settings. Let's look at how to resize text in popular apps.

Google Chrome and Yandex Browser

In browsers, you can configure the scale of the display of pages:

1. Open your browser and tap the icon. ⋮ (three points) in upper right corner.
2. Select Settings → Availability.
3. Activate the text scale option and move the slider to the desired value (from 50% to 200%).
4. To reset, hold your finger on the screen and select Reset Scale.

Telegram and WhatsApp

In messengers, the font size changes through the MIUI system settings, but there is a workaround:

• 🔍 In Telegram, pin any chat and select Change text size (available in versions 9.0)+).
• 📱 WhatsApp can only reduce the font through a change DPI (see section 3).

Instagram and TikTok

These apps ignore the system font settings, and the only way to reduce text is to use third-party utilities like App Settings (requires root) or enable Easy Mode in your account settings.

💡

If the DPI changes, the applications start to work incorrectly, clear their cache in Settings → Applications → Application Management → [App Name] → Clear the cache.

5. Hidden settings via ADB (for advanced)

If standard methods don't work, you can use Android Debug Bridge (ADB) to force you to resize your font, which requires connecting your phone to your computer and having basic command line knowledge.

Step-by-step:

1. Download and install Platform Tools from the official Google website (link).
2. Enable USB debugging on your phone: Settings → Additional → For developers → Debugging over USB
3. Connect your phone to your PC through USB-cable and select File Transfer Mode.
4. Open the command prompt (cmd on Windows or Terminal on macOS/Linux) and type: adb devices Make sure your device appears in the list.
5. Execute a command to change the font size (for example, on the 80% Adb shell settings put system font_scale 0.8
6. Reboot the phone.

Permissible values for font_scale:

• 0.8 – 80% (minimum size)
• 0.85 — 85%
• 0.9 — 90%
• 1.0 - 100% (standard)
• 1.3-130 percent (maximum size)

⚠️ Attention: incorrect value font_scale (for example, 0.5) In this case, reset the settings via the command: adb shell settings put system font_scale 1.0

6. Solving problems after changing font

Sometimes, when you reduce the size of the text, you get a problem, like blurry letters, downed animations, or errors in applications, and let's look at the typical problems and how to fix them.

Problem 1: The text has become blurry

Reason: discrepancy between DPI and physical screen resolution.

Decision:

• Return the standard DPI settings (see Section 2).
• If you use Smallest width, set a value multiple of 40 (e.g., 360, 400).
• Nana AMOLED-Include the option to improve text clarity in Settings → Screen. → Additionally.

Problem 2: Apps won’t open or fly out

The reason: conflict with the changed DPI.

Decision:

• Clear the cache of the problem app.
• Update the app to the latest version.
• If the error persists, return the standard DPI and use alternative methods (e.g, font_scale through ADB).

Problem 3: No font settings are saved after rebooting

Reason: system files crash or conflict with the theme of design.

Decision:

• Set a standard theme in Settings → Themes.
• Perform a reset of screen settings: Settings → System → Reset settings → Reset screen settings
• If the problem persists, check your phone for viruses using Mi Security.

💡

Before experimenting with DPI or ADB, always back up your data through Settings → Additional → Backup and Reset. This will allow you to quickly restore the phone to work if you crash.
