Xiaomi smartphone owners often want to personalize the device, and changing the system font is the easiest way to make the interface unique. The default Roboto font can seem boring or hard to read due to visual features. Fortunately, the MIUI shell installed on Redmi 9 provides ample opportunities for customization without the need for root rights.
The process of replacing the font with Redmi 9 takes only a few minutes and does not require a computer connection or complex manipulation of system files. You can choose from thousands of free styles in the official store or download your own.mtz file from trusted sources. This change will affect the entire interface, from the settings menu to the display of text on social networks and instant messengers.
Before you start installing exotic fonts, it's important to understand that some styles may be less readable in everyday use. When you experiment with design, you change the visual perception of information, so you should approach the choice responsibly. In this article, we will discuss in detail all available methods of changing the font, including hidden settings and the use of third-party launchers.
Official MIUI Theme and Font Store
The safest and easiest way to change the look of text on your Redmi 9 is to use the built-in Themes app.This is a system solution from Xiaomi that is fully integrated into the shell and does not cause conflicts. To get started, make sure your device is connected to a Wi-Fi network or mobile Internet, as the font directory is updated in real time.
Open the Themes app on the home screen or in the Tools folder. At the bottom of the screen, find and select the Profile tab (human icon). In the menu that opens, you will be interested in the Font item. By clicking on it, you will be taken to a directory that presents hundreds of design options, from classic to decorative.
When choosing a font, look for a preview that shows what the numbers and letters of the alphabet will look like. Some fonts only support Latin, which will make the Russian text on the screen unreadable as a set of characters. After choosing the appropriate option, click Download and then Apply. The system will automatically apply the changes, and the screen will go out for a moment.
⚠️ Note: Some fonts in the official store may be paid or require a Mi Premium subscription.Be sure the price is listed as "Free" before downloading unless you plan to spend funds.
- 🎨 A huge library of styles updated weekly.
- 🔄 Ability to return to standard font instantly.
- 🌐 Support for regional fonts for different languages.
- ⚙️ Automatic application to all system applications.
Installation of fonts from third-party MTZ files
If you don’t find anything in the official directory, you can use third-party files with the.mtz extension. This is a format of theme and font archives specially developed for MIUI. These files are often created by independent designers and may contain unique styles that are not available in the official store.
To install, you will need to download the font file from a trusted source on the Internet. After downloading the file to your phone's memory, go to the Topic → Profile → Fonts app. In the upper right corner, click on the menu icon (three dots or strips) and select the option Import fonts or Local.
💡
If importing through the application does not work, try renaming the file, leaving only the Latin letters in the title, and repeat the procedure.
The system will find the downloaded file and prompt it to install, a method that is especially useful for users who want to install a Google Sans or iOS System Font font on their Redmi 9.
| Parameter | Official store | Third-party file (MTZ) |
|---|---|---|
| Security | Tall. | Medium (depending on the source) |
| Diversity | Limited to moderation | Unlimited |
| Compatibility | 100% | Possible coding errors |
| Difficulty | Minimum | Requires file search |
Use of the zFont 3 application
One of Xiaomi’s most popular customization tools is the zFont 3 app. It’s a powerful harvester that lets you not only change fonts, but also install emojis from other versions of Android or iOS.The app is available on Google Play and runs on Redmi 9 without restrictions.
After installing and running the app, you need to go to the Local tab or select a font from the list of popular ones in the Recommended section. zFont 3 will automatically determine the model of your phone (Redmi 9) and suggest the appropriate installation method. Most often this happens through the built-in MIUI Theme Editor mechanism.
☑️ Algorithm of operation in zFont 3
The main advantage of this method is that you can preview the font on screenshots of the interface before installing it, you can see what WhatsApp, Telegram or the settings menu will look like. If you like the result, follow the instructions on the screen for the final activation through the Themes app.
⚠️ Attention: zFont 3 contains ads. Be careful when you click buttons so that you don't accidentally click on an advertising link instead of using font.
- 📱 Support for the installation of emojis from Apple and Samsung.
- 👁️ Preview of the font in the interface.
- 🛠️ Built-in editor to create your fonts.
- 🔄 Automatic update of the font database.
Setting the size and fat content of the text
Sometimes the problem with readability is not the style of the letters, but the size or saturation of the letters. Redmi 9 can fine-tune these parameters through a standard menu, and this is especially true for people with low vision or those who prefer a minimalist look.
Go to Settings → Screen → Text size and fatness. Here you'll see two sliders. One is responsible for the size of the type across the system, the other is for the saturation (fat), and as you move the sliders, you immediately see changes in the text example on the screen.
Hidden DPI setting
Increasing the boldness of text often makes the font more contrasting and easier to perceive in bright sun. However, too bold font can lead to the “sticking” of letters in words, especially in narrow columns of text. The optimal value for Redmi 9 with its screen resolution is a standard or slightly increased value of boldness.
Remember that changing the size of text affects the layout in some applications. If you set too large font, the buttons in the menu may shift or become unclickable, in which case resetting the display settings to factory values helps.
Change of font through third-party launchers
If you don’t like system methods or want to change the font only on the desktop, you can use third-party launchers. Apps like Nova Launcher, Microsoft Launcher or Smart Launcher allow you to completely replace the MIUI shell.
Most launchers have a Decoration or Look & Feel section in their settings, where you can select the Font property. Launchers often have a built-in font database or allow you to point the path to the font file in the phone's memory, and this change will only affect the icons, widgets and menus launched through this launcher.
The downside of this approach is that the font will not change in system settings, caller or messages if they use system rendering of text, but for customization fans, it is a great way to create a unique visual style of the workspace without deep interference with the system.
💡
Third-party launchers change the font only within their interface, without affecting system applications such as settings or contacts.
- 🚀 High speed of the interface.
- 🎨 Flexible setting of grid and icons.
- 📂 Ability to create profiles for different tasks.
- ⚠️ Possible increase in battery consumption.
Returning to Standard Font and Solving Problems
In the experiment, you may find yourself in a situation where the new font is not displayed correctly: instead of letters, squares appear, the text becomes unreadable or the interface “floats”, in which case you should not panic, since Redmi 9 has a simple mechanism for rolling back changes.
The quickest way to get it back to the Topic → Profile → Fonts app is to go back to the top of the screen, usually with a button or card called Default or System. Click on it and confirm the application. The interface will reboot by returning the standard Roboto font.
If the Themes app doesn't open because of font conflict, try running your phone in Safe Mode. To do this, press the power button, and then hold your finger on the Turn off button on the screen for a long time until you prompt to go to Safe Mode. In this mode, third-party fonts turn off, and you can delete the problem file.
