How to change the font size on the Xiaomi phone: all the ways and hidden settings

Xiaomi’s MIUI-based smartphones offer flexible text settings, but not everyone knows where to look for these options. Font size affects not only the readability but also the user experience: too small text tires the eyes, and too large reduces the amount of information on the screen. In this article, we will examine all the official and hidden ways to change the font size on Xiaomi, Redmi and POCO devices, from basic settings to fine calibration through the developer.

The MIUI feature is that the manufacturer regularly moves menu items in new firmware versions, so the instructions for MIUI 12 may not work on MIUI 15. We took these nuances into account and provided current paths for the latest shell versions (2023-2026), and also indicated differences for older models. If you do not find the right item, use alternative methods from the article.

Method 1: Standard font size setting in MIUI

The easiest method is to use built-in display options, which works on all Xiaomi devices regardless of model and firmware version (except for the heavily outdated versions of MIUI before the 10th).

To change the font size:

1. Open the Settings app (cog icon).
2. Go to the Screen section (on some models – Display).
3. Select Text Size or Font Size and Display.
4. With the help of the slider, adjust the size: the leftmost position is the minimum font, the right is the maximum.
5. Click Ready or Apply to save the changes.

MIUI 14/15 adds a display scale option that changes not only the font size, but also all interface elements (icons, buttons, menus). If you want to zoom in only text, leave this option in the default position.

💡

If after changing the font size, some apps (such as banking) display text incorrectly, try restarting the phone.

Method 2: Change the font style (including size)

MIUI allows you to set custom fonts, which include options with a predefined size, which is suitable if a standard slider does not work or you want to radically change the appearance of the text.

How to change the style of the font:

• 📱 Go to Settings. → Screen. → Type style.
• 🔍 View the available options: Mi Sans (standard), Roboto, SF Pro and others. Some fonts have modifications with the prefixes Bold (fat) or Condensed (narrow), which visually changes the perception of size.
• 📥 If the list does not have a suitable font, click Download fonts and select from the Xiaomi collection or install your.ttf file.
• 🔄 After applying the new font, go back to the text size and adjust the slider – some fonts initially appear larger or smaller.

Note: Custom fonts may not be supported in some applications (such as WhatsApp or Telegram) where text will be displayed in the system’s standard font, and after updating MIUI, manual fonts may be reset.

Method 3: Mode for the visually impaired (maximum increase)

If standard settings don't zoom in enough, MIUI has a special mode for users with vision problems, which not only makes the font bigger, but also simplifies the interface by removing unnecessary elements.

How to set the mode:

1. Open the Settings. → Special facilities.
2. Choose Magnification or Mode for the Visually Impaired (the name depends on the version of MIUI).
3. Activate the switch Large text.
4. In the Increase Settings section, select the maximum coefficient (up to 200% in new versions).

Additional options are also available in this mode:

• 🔍 Loop: Triple touch of screen causes magnifying glass.
• 📄 High contrast: Makes the text black on a white background (or vice versa).
• 🎯 Color filters: useful for color blindness.

⚠️ Note: In the visually impaired mode, some applications (such as games) may not work correctly or display the interface in a standard size. To return the normal view, turn off the mode in Special Opportunities.

Method 4: Configure through Developer Modes

For advanced users who need to calibrate the font size accurately, the developer menu is fine. min_width, This affects the scale of all text elements.

How to enable and use developer modes:

1. Activate the developer menu: go to Settings → About Phone and 7 times click on the MIUI version. You will be notified of becoming a developer!.
2. Go back to the main Settings menu and open a new section for developers.
3. Find the minimum width item (min_width) (In some versions, the smallest width).
4. Change the value from 360dp to 411dp (to increase text) or 320dp (to decrease text).
5. Reboot your phone to make the changes take effect.

This method affects the display of all interface elements, not just the font. min_width = 411dp:

• 📱 The text in the menu and applications will become larger.
• 📊 Icons on the desktop will increase.
• 🔄 Some apps (such as Google Maps) may not display correctly.

⚠️ Attention: Do not set the value min_width below 320dp — This can cause system menus to fail: 360–480dp.

Method 5: Change the font for individual applications

Some apps (e.g. Chrome, Telegram, or VK) have their own text size settings that don’t depend on system settings, which is handy if you only need to zoom in on one application.

Examples for popular applications:

• 🌐 Google Chrome: Open the menu (three dots) → Settings → Availability → Text size. Options available from Very Small to Very Large.
• 📱 Telegram: Settings → Appearance → Font size. You can choose a fixed size here or enable Automatic Scale.
• 💬 WhatsApp: No font settings, but System Scale can be used (see Method 1).
• 📖 Book readers (FBReader, Moon)+ Reader: In the display settings there are separate parameters for font size, line spacing and fields.

If the application does not support changing the font, try using system zoom (see Method 3) or install an alternative launcher (like Nova Launcher), which allows you to customize the size of the icons and text separately for each shortcut.

Method 6: Reset the font settings to standard

2. Move the slider to the middle position (usually marked as Default).
3. If you've changed min_width In Developer Mode, Return the Value 360dp.
4. Go to Settings → Applications → Application Management, find Themes and click Erase Data (this will reset custom fonts).
5. Reboot the phone.

If there are problems with the display, perform a soft reset:

• 🔄 Press the power button and select Reboot.
• 📱 After turning on, check if the artifacts have disappeared.
• 🔧 If the reset didn't help, try updating. MIUI up to the latest version (some firmware has scaling bugs).

⚠️ Note: Resetting the Topic app will remove all installed wallpaper, fonts and icon styles. Before doing so, save your favorite themes to My Themes.

💡

If the font still doesn’t show correctly after reset, the problem may be in the damaged cache of the system, in which case only a complete reset to factory settings (with loss of data) will help.
