How to increase the font on the Xiaomi smartphone: from standard settings to hidden features

Xiaomi’s MIUI-enabled smartphones offer flexible text settings, but not everyone knows how to resize the font correctly. Small text creates discomfort when reading, especially for people with vision problems or when using a phone in the sun. In this article, we’ll look at all the possible ways to zoom in on the font, from basic settings to hidden features that are not available to all users.

It's important to understand that changing the font size affects not only the convenience, but also the display of the interface: some elements can be offset or cropped. We tested all methods on the Redmi Note 12 Pro+, POCO X5 Pro and Xiaomi 13 Ultra models with MIUI 14 to ensure that the instructions are up to date. If your phone runs on an older version of the firmware, some features may not be available, we will warn you about this separately.

Method 1: Standard font size change in MIUI settings

The easiest method is to use the built-in system settings, which is suitable for all Xiaomi models, including budget Redmi and flagship devices.

1. Open the Settings app (the gear icon on the desktop).
2. Go to the Screen section.
3. Select Text Size (in some versions of MIUI, the Font and the display size may be called).
4. With the slider, adjust the font size. You can get values from small to very large.

MIUI 14 also introduced a font style option where you can select one of the preset fonts (e.g. Mi Sans or Roboto) that does not affect size, but improves readability. Note: after changing the font, some apps (e.g. Telegram or WhatsApp) can ignore system settings and use their own settings.

💡

If after changing the font size of the icons on the desktop moved, go back to Settings → Screen → Element size and reduce the interface scale by 1-2 divisions.

Method 2: Use the “Increase” function (magnification) for temporary scaling

If you only need to enlarge text in certain situations (for example, when reading small print in documents or on websites), use the built-in zoom function. It works like a magnifier and is activated by triple pressing:

• 🔍 Go to Settings. → Special facilities → Increase.
• 📱 Turn on the switch Short press to increase.
• ⚙️ Set up zoom level (from 1.2)× 8×) and display style (full screen or window).

Once activated, triple tapping the screen will temporarily enlarge the area where you touched your finger.The feature is useful for viewing photos with fine details or reading PDF-However, it does not change the system font permanently and may conflict with navigation gestures (e.g. swipe down to open the notification bar).

Method 3: Scaling the display (DPI change)

To make the interface more customizable, you can change the DPI (dots per inch) setting, which affects not only the font, but also the size of all interface elements. In MIUI, this option is hidden, but it can be activated through the developer mode:

1. Open the Settings. → The phone.
2. Find the MIUI version and click on it 7 times until you become a developer!
3. Go back to the main settings menu and select a new section for developers.
4. Scroll down to Minimum Width (this is the DPI setting).
5. Set the value from 380 (large elements) to 480 (small ones). The standard value for most Xiaomi is 420.

Changing the DPI will reboot the phone. After applying, you will notice that the icons, text and buttons have become larger, but some applications (especially games) may not display correctly. On models with MIUI 13 and newer, with a DPI below 360, you may have problems displaying the Gboard keyboard.

Method 4: Installation of third-party fonts with an increased size

If you don't have enough built-in fonts, you can install custom fonts through MIUI Themes or third-party apps, like OpenDyslexic, which is designed specifically for people with dyslexia, and has enlarged characters with thickened lines to install:

• 🎨 Download a font file in.ttf format (for example, from fonts.google.com).
• 📲 Move the file to the folder MIUI/theme/fonts Indoor storage (create it if it doesn’t exist).
• 🔄 Go to Settings. → Topics → Fonts and select the downloaded font.

Not all custom fonts are displayed correctly in MIUI. If the text becomes blurry or characters overlap after installation, go back to the standard font. Also note that some banking applications (such as SberBank Online) may block work on devices with modified system fonts due to security policies.

Method 5: Using Forced Applications to Increase Text

If the system settings don't work, you can use third-party utilities, for example, Big Font (available on Google Play) allows you to zoom in to 200% of the standard size, even in applications that ignore system settings.

1. Install Big Font from Play Market.
2. Open the application and provide access in the Settings section → Special facilities → Big Font.
3. Set up the magnification level and turn on the Forced Scaling switch.

The app runs on top of the system and can conflict with some games or banking services, and it increases the load on the processor, which leads to an increase in battery consumption by 5-10%. On models with MIUI 14 and Android 13, you need to turn off battery optimization for this application to work properly.

💡

Third-party utilities to enlarge the font may violate the security policies of some applications (for example, banking).

Problems and Solutions: What to Do When the Font Doesn't Change

Sometimes users are faced with the fact that the change in font size does not apply or does not work correctly.

If none of these methods worked, check to see if your device is power-saving. In MIUI, it may limit some features, including changing the font. Also make sure the phone has the latest firmware installed – older versions of MIUI 11 and below may not have some of the features described.

💡

Before contacting Xiaomi service center about font problems, reset your settings via Settings → System → Reset → Reset all settings (without deleting data).

Comparison of methods: what way to increase the font to choose

Each of these methods has its pros and cons, depending on your goals:

• 🔹 Standard settings (text size) are the safest and most versatile method, but it doesn’t work in some applications.
• 🔍 Increase function – suitable for temporary scaling, but requires manual activation.
• ⚙️ Change of change DPI — It gives maximum customization, but can break the display in games and some applications.
• 🎨 Custom fonts – improve readability, but not all fonts are compatible with MIUI.
• 📱 Third-party utilities – solve the problem in persistent cases, but increase battery consumption.

For most users, a combination of standard settings and zoom functions is enough. If you want the largest possible text in all applications, try Big Font or change the DPI. Remember that on devices with MIUI for the global market (for example, Redmi Note 12 Global), some of the features may be limited compared to Chinese versions of firmware.

💡

The most stable result is a combination of standard font enlargement (+2-3 division) and the function of zoom for reading small text.
