How to increase the font on the keyboard Xiaomi: all the ways for MIUI and Gboard

Small fonts on the keyboard of Xiaomi smartphones are a common problem for visually impaired users or those who are used to large characters. Unlike the system font, which changes in the display settings, the text size on the keyboard is adjusted separately — and it is not always obvious where to look for these parameters, especially for owners of devices with custom firmware or outdated versions of MIUI, where the settings menu may differ.

In this article, we’ll look at 5 proven ways to increase the font on Xiaomi’s keyboard, including standard MIUI tools, Gboard settings, and alternative solutions for users with special needs. All methods are tested on current firmware versions (MIUI 14/15) and are compatible with most models of the brand, from the budget Redmi Note to the flagship Xiaomi 13/14.

1. Enlarge the font through the MIUI settings (system keyboard)

If you use a standard MIUI keyboard (it is activated by default on new devices), you can change the font size in the system settings. This method works on all Xiaomi, Redmi and Poco smartphones with MIUI 12 firmware and later.

Instructions:

• 📱 Open the Settings app (cog icon on the desktop).
• 🔍 Go to the Additional Settings section → Language and input → Current keyboard.
• 🖋️ Tap on the keyboard item. MIUI (System keyboard on some models).
• 🔎 In the menu that opens, find the option Font Size or Keyboard Size.
• 📏 Move the slider to the right to enlarge the font. Changes apply immediately.

On some devices (like the Poco X3 Pro or Redmi 9A), this option may be hidden in the keyboard’s Appearance submenu, and if the slider is not available, your version of MIUI does not support this feature and you will have to use alternative methods.

2. Adjust font size in Gboard (Google Keyboard)

Gboard is the most popular alternative to the standard keyboard on Xiaomi, and offers more customization options, including font size adjustment. If you pre-installed Gboard from Google Play, follow this instruction:

How to change the font:

1. Open any application where the keyboard appears (such as Messages or Notes).
2. Touch the badge. ⚙️ (gear) on the Gboard panel to open settings.
3. Select Topics → Setting up the topic.
4. Slip the option of key size or text on the keys (depending on the version of the application).
5. Move the slider to the right to enlarge the font. The preview will be displayed immediately.

You can also include bold font in Gboard for better readability. To do this, activate the Fat Text Settings switch in the same Theme Menu. Note that too large font can crop characters on small screens (for example, on Redmi A1 or Poco C40).

💡

If there is no option to change the font in Gboard, upgrade the app to the latest version on Google Play. Developers are adding new features regularly.

3. Use of the regimen for the visually impaired (TalkBack and increase)

For users with severe vision problems, Xiaomi offers a special zoom mode that scales not only the system interface, but also keyboard elements, which is suitable if the standard settings do not give enough magnification.

Activation of the regime:

• 👁️ Go to Settings. → Special facilities → Increase.
• 🔍 Turn on the switch Short zoom (tap the screen three times with three fingers to activate the switch).
• 📱 Alternatively, activate TalkBack (Voice Assistant for the Visually Impaired) – it automatically enlarges fonts in all applications, including the keyboard.

The downside of this is that the whole interface is increased, not just the keyboard, and some gestures (like swipes) may work differently, so if you want to zoom in on just the keyboard font, you'd better use the first two sections.

4. Installation of alternative keyboards with large font

If the built-in settings are not suitable, you can install a third-party keyboard with support for large font.

After installing the alternative keyboard, it must be activated:

1. Go to Settings → System → Language and input → Current keyboard.
2. Select the keyboard installed (e.g. SwiftKey).
3. In the settings of the new keyboard, find the Appearance or Themes section and adjust the font size.

Important: Some keyboards (like Big Keys) may conflict with MIUI gestures, such as swipe back, in which case disable conflicting gestures in Settings → Display → Full-screen gestures.

5 Manual modification of system files (for advanced users)

If none of the above methods worked, you can manually edit the system files that display the keyboard, which requires root rights and is only suitable for advanced users.

Instructions (for MIUI based on Android 11-14):

1. Install a file manager with root support (such as Root Explorer).
2. Go to /system/usr/keyboard/ (the path may vary depending on the model).
3. Find the file. keyboard_layout.xml or font_size_config.xml.
4. Open the file in the text editor and find the line with the textSize option.
5. Increase the value (for example, from 16sp to 24sp) and save the file.
6. Reset the device.

This method is risky and can disrupt the stability of the system, and we recommend using it only if:

• 🛠️ You have experience working with ADB root.
• 📱 Device not warranty (root opening voids Xiaomi warranty).
• 🔄 You are ready for a possible resetting of settings.

6. Additional Tips for Better Readability

In addition to increasing the font, you can improve the visibility of the keyboard in other ways:

• 🎨 Change the theme of the keyboard: in Gboard or MIUI Keyboard select a high-contrast theme (e.g. black keys on a white background).
• 🔦 Set up the lighting: in Settings → Display. → Brightness increase the brightness of the screen or activate adaptive backlight.
• 👓 Use an external keyboard: Connect a physical keyboard with large buttons via Bluetooth (e.g. Logitech) K380).

If you often type in the dark, turn on Night Mode in the display settings – it reduces the strain on the eyes and makes the text on the keyboard more distinguishable.

💡

Combining large fonts with a high-contrast keyboard theme greatly improves readability, especially in bright sunlight.

⚠️ Note: Some Xiaomi models (e.g. Redmi) 7A POCO M2) If you zoom in too much on the keyboard, you may lose the hints (autocomplete). 1-2 item or disable the prompts in the keyboard settings.
