The fine print on the Xiaomi Mi 7 screen can be uncomfortable — especially if you’re used to large text on previous devices or have vision problems. Fortunately, MIUI offers several ways to zoom in text, including hidden options for fine-tuning. But not all of them are equally effective: some methods only increase the system font, others affect applications, and still others can lead to blurring the interface or conflicts with individual programs.
In this article, we will discuss 5 proven ways to change the font size on Xiaomi Mi 7, including solutions for users with MIUI different versions (from 12 to 14), you will learn how to circumvent the limitations of the system, what applications will help in customization and what to do if the text after changes is displayed incorrectly, and also unique life hacks for the visually impaired, which Xiaomi does not advertise in the standard settings.
Before you start making changes, make sure your Xiaomi Mi 7 is updated to the latest available version of MIUI. This is important, as older firmware (e.g. MIUI 10-11) may have some features missing or may work differently. You can check the relevance of the software in the Settings menu → About phone → System Update.
1. Standard change of font size in MIUI
The easiest way to zoom in on a font is to use the built-in display settings, which work on all versions of MIUI and doesn't require superuser rights, but it has a limitation: maximum text size may not seem sufficient for users with severe visual problems.
To change the font in a standard way:
- Open Settings (the gear icon on the main screen).
- Go to the Screen section.
- Select Text Size (in some versions of MIUI it may be called Font and display size).
- With the slider, adjust the font size. You can get values from Small to Very Large.
- Click Ready or Apply to save the changes.
⚠️ Attention: B MIUI 14 after changing the font size, some system applications (for example, Camera or Gallery) may display the text incorrectly - with cropping or overlaying on interface elements.
If the standard maximum (Very large) is not enough for you, move on to the following methods. Also pay attention to the screen zoom settings - they are in the same section of the Screen and allow you to increase not only the text, but also all interface elements (icons, buttons, etc.).
💡
To quickly open the screen settings, swipe twice over the top of the display (where the time and notifications are displayed) and tap the Screen icon in the Quick Settings Panel.
2.The regime for the visually impaired: the hidden possibilities of MIUI
Xiaomi has built a special high contrast mode and additional options for visually impaired users into MIUI, which often go unnoticed because they are hidden in the Special Features menu.
You can activate the extended font settings as follows:
- 🔍 Go to Settings. → Special facilities → Vision.
- 📱 Enable the option to enlarge the font (if it is in your version) MIUI).
- 🎨 Activate High Contrast – This will make the text clearer against the background of the interface.
- 🔄 Turn on Color Inversion (optional) if you are more comfortable reading white text on a black background.
Some firmware (e.g. MIUI 13 for Xiaomi Mi 7) also has screen scale settings, which allows you to increase text to 150% of the standard size – 20% more than the maximum value in conventional settings.
⚠️ Warning: High contrast mode may conflict with dark theme MIUI. If after activation the text became poorly readable, try to turn off the dark mode in Settings. → Screen. → Dark subject.
| Function | The effect | Side effects |
|---|---|---|
| Enlargement of font | The text is getting bigger (up to 150%) | Can "move" elements in some applications |
| High contrast | Text is clearer on a light/dark background | Color distortion in games and multimedia |
| Color inversion | White text on a black background | Incorrect display of photos |
| Screen size | Increases all interface elements | Screen workspace is reduced |
3. Use of third-party applications for font customization
If you don't like the built-in MIUI options, you can use third-party solutions. There are several types of applications for changing the font:
- 📱 Launchers (such as Nova Launcher or Apex Launcher) – allow you to adjust the font size for icons and inscriptions on the home screen.
- 🔤 Font managers (e.g. iFont or FontFix) – replace the system font with custom font with the ability to scale.
- 🔍 Vision-impaired utilities (e.g. Big Font or Magnification Gestures) – increase text in individual applications.
The most reliable option is iFont, which is root-free and allows you to:
- Install a larger font size (including custom fonts) TTF-file).
- Apply changes to the entire interface or individual applications.
- Return the standard MIUI font in one click.
⚠️ Note: When using iFont or similar programs, turn off automatic updates to system fonts. MIUI (Settings → Additionally. → Font updates. Otherwise, after the next update, your settings will reset.

4. Change font size via ADB (for power users)
If you're ready to dive into the technical details, you can resize the font through Android Debug Bridge (ADB), a method that offers the most flexibility, but requires connecting the phone to a computer and basic command line knowledge.
Step instructions:
- Turn on Developer Mode on Xiaomi Mi 7: Go to Settings → About Phone. 7 times click on the MIUI version until the notification “You became a developer” appears.
USB debugging
Settings → Additional → For Developers
adb shell settings put system font_scale 1.3where 1.3 is the scaling factor (you can set the value from 0.8 to 1.5).
Reset the device.
To return the standard font size, follow the command:
adb shell settings delete system font_scale⚠️ Note: Some apps (such as Google Maps or YouTube) may ignore the global font settings set through the ADB. In this case, you will have to change the scale manually in the settings of each application.
What if the ADB does not recognize the device?
5. Solving problems after changing font
Enlarging the font can lead to unexpected consequences, from small visual bugs to complete failure of individual applications.
| Problem. | Reason. | Decision |
|---|---|---|
| Text is cut or overlaid on buttons | The font scale exceeds the application layout limits | Reduce font size by 10-15% or use ADB to fine-tune |
| The app flies off at launch | Conflict with custom font (especially in banking applications) | Return the standard MIUI font or add the app to exceptions |
| Blurred text in games or videos | Scaling is applied to multimedia | Turn off font enlargement for a specific application in special features settings |
| Navigation gestures do not work | Increased screen size shifts touch zones | Switch to navigation buttons in Settings → Screen → Navigation |
If after the changes the interface became uncomfortable, but you do not remember what settings were touched, reset the display parameters:
To activate the voice reading screen:
- Open Settings → Special Opportunities → TalkBack.
- Turn on the function and follow the setup instructions.
- To read the text, swipe two fingers across the screen from top to bottom.
⚠️ Attention: TalkBack changes the standard control gestures, for example, one touch will sound the element, and activation will require double tap. To turn off mode, hold two fingers on the screen for 3 seconds.
