How to change the font on Xiaomi Redmi Note 9: 5 proven ways

The standard font on the Xiaomi Redmi Note 9 is not popular with all users — some people think it is too small, some lack style, and some just want a variety. Fortunately, MIUI offers several ways to change the system font without root rights or complex manipulation. In this article, we will analyze all the current methods, from embedded tools to third-party applications that work on any version of the firmware (including MIUI 12/13/14).

It's important to understand that changing the font is not just an aesthetic change, but also a matter of convenience. For example, increasing the size of the text can significantly improve readability for people with vision problems, and choosing a sans-serif typeface (for example, Roboto or San Francisco) is often recommended for long screen reading, while some methods require caution: wrong actions can lead to interface malfunctions.

If you've never changed your system settings on the Redmi Note 9 before, don't worry, we'll explain every step in detail, including the hidden nuances, like why a MIUI update might reset the font to the standard one, or how to get it back if the new font is inconvenient, and for those who like experimenting, we've added a section about installing custom fonts through ADB, which is a little more complicated, but opens up thousands of options.

1. Standard MIUI settings: change the font without third-party applications

The easiest and safest way is to use the built-in MIUI tools. Xiaomi Redmi Note 9 based on MIUI 12 and newer supports changing the font directly in the system settings.

1. Open the Settings app (the gear icon on the home screen).
2. Go to the Screen section.
3. Select the Font option (in some versions of MIUI it may be called Font Style).
4. Scroll through the list of available fonts, and you will see both standard fonts (Mi Sans, Roboto) and themed fonts (e.g. Mi LanPro for the Chinese market).
5. Tap your favorite typeface to apply it. The changes will take effect immediately - no reboot is required.

Note that MIUI 14 has a slightly wider font list than previous versions, and now you can find Monospace (a mono-width font that is convenient for programmers) and Casual (a handwritten style), but if you want something more original, you'll have to use third-party solutions.

💡

If some apps (e.g. banking) display text incorrectly after changing the font, try returning the standard Mi Sans, which is due to security restrictions in MIUI.

Also in this menu you can adjust the font size and scale of the display:

• 📏 Font size – regulates only text (from “Very small” to “Very large").
• 🔍 Display scale – changes the size of all interface elements (icons, buttons, menus).

💡

MIUI 14 has introduced the Adaptive Font feature, which automatically adjusts text size to lighting, and can be included in Settings → Screen → Font → Adaptive Size.

2. Installation of fonts through MIUI themes: hidden opportunities

Few people know, but the Xiaomi Redmi Note 9 allows you to change the font through the Themes app, which gives you access to hundreds of styles, including exclusive fonts from MIUI designers.

1. Open the Themes app (if it isn’t on the home screen, search through search).
2. Go to the Font tab (it can be hidden behind the button "More" or "Category").
3. Scroll through the list of available fonts. There are both free and paid options (the price is usually 10-50 rubles).
4. Click on the font you like, then select Apply. The system downloads and installs it automatically.

The advantage of this method is that the Topic fonts are optimized for MIUI and rarely cause crashes, and you can also find themed sets like cyberpunk or retro typefaces, but there is a downside: once you reset your settings or update your MIUI, the font can reset and you have to reset it.

If you didn’t find the right font in the standard directory, try:

• 🔄 Update Themes app via Play Market – sometimes new fonts appear after an update.
• 🌐 Switch to another region in settings MIUI (India or China – more options available in some countries.
• 📥 Download the.ttf font from a reliable source and install it through Topics → Mine. → Local.

3. Third-party applications: iFont and other tools

If you don't have enough built-in options, you can use third-party apps, and the most popular is iFont, which allows you to install custom fonts without root rights. Here's how it works on the Redmi Note 9:

1. Download iFont from the Play Market.
2. Open the application and go to the Online tab (online font directory).
3. Choose your favorite font and click Download.
4. After download, click Set. The app will offer two options: 📱 MIUI Mode – for Xiaomi smartphones (recommended). 🤖 Manual Mode – for other devices (requires manual action).

MIUI Mode

iFont supports more than 4,000 fonts, including rare and authorial ones, but beware: some fonts may not display correctly in system applications (such as Settings or Phone), and after the MIUI update, the font may reset and have to be reinstalled.

Backup important data | Check the vacant space (need ~50MB) | Close all background applications | Connect to Wi-Fi (fonts weigh up to 10MB) | Disable battery optimization for iFont-->

💡

Before installing the font through iFont, check the reviews in the directory. Some users complain that serif fonts (such as Times New Roman) are not readable on smaller Redmi Note 9 screens (6.53 inches).

4. Installation of font via ADB: for power users

If you need to install a unique font that is not in the directories, you can use ADB (Android Debug Bridge), which requires connecting the phone to a computer, but gives you complete control over the system fonts. Importantly, the wrong commands can cause MIUI to malfunction!

Here's the step-by-step instruction:

1. Download and install ADB Tools on your computer.
2. On Redmi Note 9, turn on Developer Mode: Go to Settings → About Phone. 7 times click on the MIUI Version until the notification “You’ve become a developer” appears. Return to Settings → Additional → For Developers and enable USB Debugging.

chmod 644 /system/fonts/MiSans.ttf




reboot

Once the reboot is over, the font will be replaced, and this method allows you to install any typeface, including those that are not supported through the Themes or iFont, but there are risks:

• ⚠️ If the font file is corrupted, the system may freeze on the boot.
• ⚠️ After updating MIUI The font will reset and the procedure will have to be repeated.
• ⚠️ Some banking applications (such as SberBank or Tinkoff) can block work on devices with modified system files.
