How to increase the keyboard on Android Xiaomi: the complete guide

The ease of typing on a smartphone is directly dependent on how comfortable the user is with the on-screen keyboard. Owners of Xiaomi, Redmi and Poco devices often face situations where standard button sizes seem too small for fingers or vision, this is especially true for people with large fingers or those who have difficulty with fine motor skills.

Fortunately, the Android operating system and the MIUI shell (and the new HyperOS) provide a lot of customization options, so you can change not only the height of the panels, but also the size of the characters you display, and turn typing from anguish into a fun and fast process, eliminating random taps.

In this article, we'll take a look at all the scaling options available, and we'll look at the built-in tools, the settings of popular virtual keyboards, and the hidden features that not everyone knows about, and your challenge is to choose the method that fits your physiologic and typing habits perfectly.

Use of built-in Gboard settings

The vast majority of Xiaomi smartphones come with Google’s Gboard keyboard preinstalled, one of the most functional input tools that has its own independent settings interface. To get started, you need to get into the settings menu of that particular app, not the phone’s general settings.

Open any application that requires text input, and call the keyboard. On the top toolbar, find the gear icon or press the space button if the menu is hidden. In the window that opens, select Settings, then go to Preferences, and that's where the slider that controls the height of the rows with the letters is hidden hides.

⚠️ Warning: Changing the height of the keyboard in Gboard can cause the top row of buttons to overlap some of the text in some applications with a non-standard layout.

By moving the slider to the right, you increase the size of the buttons, making them more convenient to press. The system automatically adapts the layout, keeping the proportions. If the standard maximum is not enough, you should pay attention to the additional zoom options at the very bottom of the keyboard settings menu.

• 📏 Move the height slider smoothly, checking the result in real time.
• ⌨️ Make sure the “floating keyboard” option is enabled for added convenience.
• 🔄 Reset the settings to factory if the interface has become unreadable.

Adjust the font and scale of the Android system

If changes to the keyboard itself don't work, the problem may lie in the system settings of the display. Android allows you to globally change the font size and scale of interface elements. This affects all applications, including the input screen, making the letters bolder and larger.

To access these options, go to Settings on your Xiaomi smartphone. Find the Additional or Advanced Settings section, and then select Text Size. Here you will see a scale that adjusts the font and a separate scale for the size of the interface elements.

Scaling up is a radical solution that changes the way the phone looks, the buttons on the menu, the text in the messages, and of course the characters on the keyboard, but it's worth remembering that on low-resolution screens, it can lead to some elements simply not fitting on the screen.

Use these settings with caution. If you find it difficult to navigate the menu after the changes, just return the sliders to their original position. The optimal is to increase the font by 1-2 divisions without changing the scale of the interface.

Alternative keyboards: SwiftKey and others

When standard MIUI and Gboard tools have exhausted their potential, third-party developments come to the rescue. Microsoft SwiftKey is famous for its advanced predictive input algorithms and flexible look and feel settings, allowing you to change not only the size, but also the theme, font and keyboard location.

After installing the app from Google Play and activating it as your primary input method, open the SwiftKey Settings menu. Go to the Layout and Keys section. Here you will find detailed keyboard height settings that often allow you to make keys even larger than in a standard Gboard.

Other popular options, like Fleksy or Typewise, offer a completely different approach to text input, such as Typewise using a hexagonal layout where the buttons are arranged like cells, which physically increases the area of each key, which is ideal for people with large fingers or low vision.

• 📱 SwiftKey offers excellent adaptation to Russian language.
• 🎨 Opportunity to adjust the color and transparency of the background keys.
• 🧠 Smart auto fix reduces the number of typos on a large keyboard.

Choosing an alternative keyboard is a matter of personal preference. Try a few options to figure out which input engine and which button geometry suits you best. Don't be afraid to experiment, as switching between keyboards takes only a few seconds.

One-hand mode and floating keyboard

Sometimes the problem is not the absolute size of the buttons, but the inability to reach the edges of the screen with your thumbs. In such cases, Xiaomi smartphones effectively run one-hand mode or floating keyboard mode. This does not increase the buttons themselves, but narrows the input area, making it accessible.

To activate floating mode in Gboard, press and hold the comma or language switch button (depending on the version), then select the floating window icon. The keyboard will unstuck from the bottom of the screen, and you can move it and resize it, stretching around corners.

This is particularly useful when you use your smartphone upright, so you can move the keyboard sideways and reduce the overall width, which automatically makes the buttons larger relative to the area available, and it's a kind of digital zoom for the input area.

⚠️ Note: In some horizontally orientation games or applications, the floating mode may not work properly or may overlap important controls.

It’s also worth checking the One-Hand Mode settings in the MIUI system itself. Go to Settings → Additional → One-Hand Mode. Activating this feature allows one swipe to narrow the entire screen, including the keyboard, to a comfortable size, which indirectly solves the problem of reaching the keys.

Hidden opportunities through engineering menu and ADB

For advanced users who are not afraid of complex manipulations, there are ways to change the pixel density (DPI) through USB debugging, which allows you to make the interface, including the keyboard, huge, but this method requires a connection to a computer and the use of the command line.

First, you need to activate the developer mode. To do this, Xiaomi needs to quickly click on the MIUI version 7 times in the About Phone section. Then, in the Developer menu, turn on "Debugging on USB." Connect the phone to your PC and use the adb shell wm density command to change the density value.

adb shell wm density 400

The standard value is usually around 360-420 DPI. Reducing that number (like 300) will make all elements smaller and increasing it (like 500-600) will make it larger.

Using ADB commands gives you complete control over the rendering of the system, and you can customize the scale to your needs, without the constraints imposed by the interface manufacturers, but remember, this is an interference with the system's display files.

Frequent problems and their solutions

Even after the right setup, users can encounter artifacts: keyboards can block the input field, letters can “leave” the screen, or parts of words disappear, often in a conflict of system-scale and application-specific settings.

If you notice that after enlarging the keyboard, a string with numbers or characters is lost, try changing the orientation of the screen or temporarily disabling predictive input. Sometimes the problem is solved by simply restarting the device, which applies new font parameters to all running processes.

• 🔍 Check if the Loops mode is included in special features.
• 📉 Reduce the scale of the system if the buttons become too bulky.
• 🗑️ Clear the keyboard app cache through the application settings.

💡

If the keyboard doesn’t show up correctly after the MIUI update, try removing the keyboard updates in the app settings by returning to the factory version and then updating it again through the Play Market.

It is important to understand that some “heavy” design themes for MIUI may conflict with non-standard keyboard sizes. If you use a custom theme, try switching to standard to eliminate this factor.

Results and recommendations for the choice of method

Enlarging the keyboard on Xiaomi is a multi-way task, from simple sliders in settings to complex system commands. For most users, a combination of adjusting the height in Gboard and easily zooming in the system font will be enough.

Don't immediately change the DPI unless you really need it. Start with the least invasive methods. Printing comfort is a balance between the size of the buttons and the amount of content you see on the screen.

💡

The optimal result is achieved by combining the keyboard height setting in the application and the system font, without changing the global scale of the interface.

Update your keyboard app regularly as developers are constantly improving ergonomics and adding new zoom capabilities.
