How to increase the size of letters on the keyboard of the Xiaomi phone: all the ways

Why the small print on the keyboard prevents you from using a smartphone

Many Xiaomi, Redmi and POCO smartphone owners have a problem with the letters on their keyboard being too small, which creates discomfort when typing, especially for people with visual impairments or when using the device in the bright sun. Unlike the system font, which changes in the display settings, the size of the keys and characters on the keyboard is adjusted separately — and it is not always obvious where to look for these parameters.

Complicating the problem, the keyboard settings menu may differ from 12 to 14 in different versions of the MIUI shell, and the result may be influenced by the type of keyboard used: standard Gboard (from Google), branded Mi Keyboard or third-party solutions like SwiftKey. In this article, we will discuss all the current ways to increase the font, from basic settings to hidden functions for power users.

It's important to understand that changing the size of letters doesn't always involve scaling the keyboard itself, sometimes you need to adjust the size of the keyboard, the height of the lines, or even the style of the design, and each parameter is responsible for its part of the problem, and if the characters still seem too small after the changes, it may be the contrast settings or the color scheme.

Method 1: Change the font size in the settings of the standard Mi Keyboard

The Mi Keyboard is the default keyboard on most Xiaomi devices, and its settings allow for flexible character size adjustment, but the menu is hidden deeper than the competition.

1. Open any application where the keyboard appears (such as Notes or Messages).
2. Touch the gear badge (⚙️) in the top row of the keyboard to open its settings.
3. Go to the Topics and layout section → Keys size.
4. Move the text size slider to the right to enlarge the font, and you can change the height of the keys if the characters appear "compressed."

If the text size slider is not available, then your version of the Mi Keyboard is outdated. Update it via Google Play or use an alternative method from the next section.

💡

The Mi Keyboard has a hidden feature called "Enlarged Text" that is activated by triple pressing key 123 digitally, and the font will temporarily become 20% larger.

Notice the key transparency option, if it's on, the characters can visually merge with the background, turn it off or set it to 0% for better readability.

Method 2: Configure Gboard (keyboard from Google)

Gboard is the most popular alternative to the standard keyboard on Xiaomi, and its advantage is its versatility: the font settings are synchronized with your Google account and applied on all devices.

• 📱 Open the phone settings → System and device → Language and input.
• 🔍 Find Gboard in the keyboard list and tap it.
• 🎨 Go to Topics. → Set up the topic → Size of text.
• 📏 Move the slider to a convenient value (maximum - 150%).

Gboard also has a floating keyboard feature (in the layout section), and if you turn it on, you can stretch the keyboard across the screen with two fingers, which indirectly increases the size of the characters by scaling the entire block.

⚠️ Note: Some versions of Gboard reset the font settings after the update. To avoid this, lock the version of the app into Google Play (turn off auto-update).

Method 3: System-based font scaling (affects all applications)

If the problem is not just the keyboard, but the fine print throughout the phone, it makes sense to change the system zoom settings, which will affect all applications, including the keyboard, but can lead to incorrect display of some interface elements.

Instructions:

1. Open Settings → Screen → Text Size.
2. Move the slider to the right. The recommended value is 110-125% (more can distort the interface).
3. Return to Screen → Display Size and select Large or Very Large.

MIUI 14 adds a "Super Large Text" feature that increases the font to 200%, but can break the layout in some applications. Activates in Special Features → Enlarge.

Method 4: Using special themes for the keyboard

Many users don't know that you can change the font size on the keyboard by installing themes. Mi Keyboard and Gboard have collections of themes with pre-configured font settings. For example, the themes with the prefix "Big" or "Large" in the title automatically use enlarged characters.

How to find and apply this topic:

• 🎨 In the keyboard settings go to the Topics section.
• 🔍 In the search bar, type in big font or large text.
• 📥 Download your favorite topic (pay attention to the rating and reviews).
• 🖼️ Use it and check if the font has become larger.

If standard themes aren't enough, you can create your own. In Gboard, this is done by Set up a theme → Create where options are available:

• Key font size (up to 150%)
• Color of text (black on a white background is better read)
• Shadow of symbols (increases contrast)

Method 5: Manually change settings via ADB (for power users)

If standard methods don’t work, you can manually edit system settings via ADB (Android Debug Bridge), which requires connecting your phone to your computer and basic command line knowledge, but allows you to customize the fonts more accurately.

Instructions:

1. Turn on Developer Mode on your phone: Settings → About Phone → 7 times tap on the MIUI version.
2. Return to Settings → Additional → For developers and activate Debugging over USB.
3. Connect your phone to your PC, open the terminal and type in: adb shell settings put system font_scale 1.3 Where 1.3 — The scaling factor (can be changed from the 1.0 before 1.5).

To apply changes to a specific keyboard, use the following commands:

• For Gboard: adb shell am start -n com.google.android.inputmethod.latin/.settings.SettingsActivity
• For Mi Keyboard: adb shell am start -n com.miui.miuikeyboard/.settings.MainSettingsActivity

⚠️ Attention: Wrong commands ADB You can disrupt the system. Before experimenting, back up through Settings. → The phone. → Backup.

Install Xiaomi drivers on PC| Enable debugging on USB| Download ADB Tools (platform-tools)| Backup phone | Check battery power (minimum 50%)

Additional tips for better readability

Sometimes the problem isn't the size of the typeface, but other factors that make it harder to read.

• 🌓 Night mode: Enable dark theme in keyboard settings (Themes) → Dark background with white letters reduces the strain on the eyes.
• 🔦 Keylighting: In Mi Keyboard, activate the Presslight in the layout settings – this will help you see the characters you are pressing better.
• 🎯 Vibration when dialing: Include tactile recoil in Keyboard Settings → Sound and vibration, which will help control the typing, even with small letters.
• 👓 Color filters: Special features → Select the color corrector mode to improve the text – it increases contrast.

If you wear glasses, check the color temperature settings of the screen (Settings → Screen → Color Mode).Warm or Reading mode reduces blue radiation, which tires the eyes and makes the text less legible.

💡

The combination of enlarged font (120%) + dark theme + tactile return gives the best result for people with visual impairment.

Frequent Mistakes and How to Avoid Them

When you change the font size on the keyboard, users often face typical problems, and here are the most common ones and how to solve them:

• ❌ Settings reset after update: This is typical for Gboard. Solution - roll back to the previous version via APKMirror or fix the current one on Google Play.
• ❌ Keyboard has become too large and doesn't fit on screen: Reduce key height in layout settings, leaving large font.
• ❌ Symbols blurred after size change: Check screen resolution in Settings → Screen. → Permission: Set a maximum value (e.g, FHD+).
• ❌ No changes are saved in Mi Keyboard: Clear the app cache in Settings → Annexes → Application management.

If you keep the font small after all the manipulations, try resetting the keyboard to the factory.

1. Open Settings → Applications → Application Management.
2. Find your keyboard (Mi Keyboard or Gboard) and tap it.
3. Select Warehouse → Clear the data (Warning: Reset all user settings!).
