Many users of brand Xiaomi and sub-brand smartphones Redmi face the problem of visual perception of the interface. This is especially true for people with low vision or those who prefer large controls to improve typing speed. Standard default keyboard settings often offer a medium font size, which may appear small on high-resolution screens.
The solution to this problem is not always obvious, since manufacturers of smartphones based on Android do not include a keyboard letter size slider in the main settings menu. However, the system provides several tools for customization. You can change the size of characters through the settings of the keyboard itself, change the color theme to a more contrasting one, or use the system settings for the scale of the entire device.
In this article we will analyze in detail all the available methods for increasing the size of letters on the virtual keyboard in the shell MIUI i HyperOS. We will look at working with the standard keyboard Gboard, which is pre-installed on most devices, and will also touch on the capabilities of third-party solutions. It is important to understand the difference between increasing the glyphs (symbols) themselves and increasing the height of the buttons, as this affects ergonomics in different ways.
Settings for the standard Gboard keyboard
The most common solution for entering text on smartphones Redmi is the keyboard Gboard from Google. It has flexible settings that allow you to adapt the appearance to the user's needs. The first step to making letters larger is to change the height of the keys. The higher the button, the larger the symbol usually appears on it, which makes it easier for your finger to hit the desired area.
To access these options, you need to open any application that requires text input, for example, messenger or notes. When the keyboard appears, look for the gear icon in the top toolbar. If it's not there, press and hold the comma key or emoji symbol to bring up the settings menu. In the list that opens, select the item Settings, and then go to the section Preferences.
Here you will find the slider Keyboard Height. Moving it to the right will cause the buttons to stretch vertically. This will not only increase the visible area of the characters, but also reduce the likelihood of typos. Please note that extreme values may obscure some of the content on the screen, so choose a balance between comfort and visibility.
⚠️ Note: Changing the keyboard height affects the entire input area. On smartphones with a small screen (up to 6 inches), the maximum value can make the top part of the keyboard inaccessible for viewing in portrait mode.
In addition to the height, in the menu Theme you can choose a design with large contrasting letters. Some themes are specifically designed for better readability, using bold fonts and bright colors on a dark or light background. This is a visual trick that often works better than simple scaling.
Using system interface scaling
If the settings of the keyboard itself do not give the desired result, you can use the global system settings Android. This method enlarges all interface elements, including application icons, menu text, and, importantly for us, keyboard symbols. This approach is the most radical, but guarantees the maximum font size.
To activate this function, go to the main settings of your smartphone through the app Settings. Find the section Display or Advanced settings, depending on your firmware version MIUI. We are interested in item Font size i Element size. By changing these parameters, you will notice how the size of the letters on the keyboard grows in real time.
The system offers several preset zoom levels. It is recommended to select a value slightly above average so as not to disrupt the layout in other applications. A font that is too large can cause text to be cut off or overlap each other in some apps. After changing the settings, the system may require a restart of the interface or the device itself to apply the changes to all services.
Before changing the scale globally, take a screenshot of the current state of the screen settings. This will allow you to quickly return everything back if the new size turns out to be inconvenient for everyday use.
It is important to note that on different models Redmi the location of these menus may vary slightly. In new versions HyperOS display settings have been unified and are in a more obvious place. If you cannot find the item you need, use the search bar at the very top of the settings menu by entering the query “font”.
Changing the keyboard theme
The visual perception of the size of letters greatly depends on the contrast and style of the font. A standard white theme with thin black lettering can appear shallow due to the low line weight of the glyphs. Changing the theme to “high contrast” or “large” solves this problem without changing the physical sizes of the buttons.
In settings Gboard go to section Theme. Here is a catalog of designs. Look for topics marked "Large" or visually evaluate the preview. Themes with dark backgrounds and bright white or yellow letters often appear larger due to the glow effect and bold font style. There are also themes that mimic physical keys with clear boundaries, which helps the eye focus on the symbol.
You can also create your own theme. Click the plus icon or the My Themes button to upload your own image or customize the colors manually. Set the maximum contrast colors for the background and text. For example, a black background and neon green letters will provide excellent readability even with a medium font size.
| Theme type | Impact on readability | Recommended use |
|---|---|---|
| Light classic | Standard, letters can merge | Day use, bright lighting |
| Dark Mode | High contrast, less eye fatigue | Night use, reading in the dark |
| High Contrast | Maximum visibility of character borders | For users with low vision |
| Color/Gradient | Medium, depends on the selected palette | For aesthetic pleasure, not for convenience |
Do not forget that some third-party themes may not display correctly when the system scale is changed. If, after increasing the font in the system, the letters on the keyboard “move” or overlap each other, return the theme to the standard one. This confirms that the problem was the incompatibility of the theme's graphic elements with the new display settings.
Third-party keyboards with flexible settings
If the built-in capabilities Gboard and system settings Android do not meet your needs, you should consider installing a third-party application for text input. The store Google Play offers many solutions where the font size is a separate, independent setting.
One of the most popular alternatives is the keyboard Microsoft SwiftKey. It is famous for its powerful predictive input engine and wide customization options. In the settings SwiftKey there is a separate section Layoutwhere you can configure in detail the height of the keys and, indirectly, the size of the characters displayed on them. In addition, the in-app theme store offers specialized large fonts.
Another option is Facemoji Keyboard or Kika Keyboard. These apps are visually oriented and often have "Large Text" modes or the ability to manually change the font size by percentage. Installing such a keyboard requires granting permissions to access data input, which is a standard procedure for any software of this type.
☑️ Installing a new keyboard
When using third-party software, it is worth considering resource consumption. Some “heavy” keyboards with lots of animations and large fonts can drain your smartphone’s battery faster Redmi. Choose lightweight versions of applications or disable unnecessary visual effects in their settings after setting a convenient letter size.
Android accessibility features
The operating system Android has a powerful block of functions for people with disabilities, which can help in our situation. The tool Magnification (Magnification) allows you to temporarily zoom in on any part of the screen, including the keyboard, using gestures or a button on the screen.
You can activate this function in the menu Settings -> Advanced settings -> Special. capabilities. Find the item Zoom and turn it on. You can now use triple-tap on the screen or a special button in the corner of the display to zoom into the area with the keyboard. This does not change the font size permanently, but allows you to see a small character at the right moment.
There is also a function Large text in the same accessibility menu. It forces a maximum font size for all supported applications. Unlike the usual resizing in the screen menu, this mode ignores the restrictions set by the developers of some apps and makes the text as large as possible.
⚠️ Attention: The "Large Text" mode may break the layout in some banking applications or games. Use it with caution and check the operation of important apps after turning it on.
For continued convenience, you can set up a keyboard shortcut to quickly access the increase. For example, pressing both volume keys at the same time can activate Magnifier. This is a useful life hack if you need to enlarge the letters only sometimes, for example, when entering a complex password.
Comparison of methods and final recommendations
We looked at several ways to solve the problem of small font on the keyboard Redmi. Each has its pros and cons, and the choice depends on your personal preference and visual acuity. There is no universal solution that would suit absolutely everyone, so you often have to combine methods.
Changing the keyboard height in Gboard is the safest and most ergonomic way. It does not break the interface of other applications and gives a real increase in the area for clicking. System zoom gives the greatest visual effect, but requires getting used to the changed appearance of the entire smartphone. Third-party keyboards offer maximum flexibility, but may consume more power.
If you use your smartphone in low-light conditions, a combination of a dark theme and a larger font will give the best results. For older users, the best choice is to turn on the accessibility mode along with installing a simple, contrasting theme. Don't be afraid to experiment with the settings to find the perfect balance.
Secret setting for advanced users
In the "For Developers" menu (which must be activated by tapping 7 times on the build number in "About phone") you can find the "Smallest width" item. Decreasing this value (in dp) results in a global increase in all interface elements, including the keyboard, even more than the standard font slider. Be careful: too low a value may make the interface unusable.
Remember that firmware updates MIUI or HyperOS may reset some user settings or change menu layout. If the letters are small again after updating your phone, simply check your saved settings profiles or repeat the setup procedure. Regularly checking that your settings are up to date will help you maintain the comfort of using your device.
Optimal strategy: start by increasing the height of the keyboard in Gboard and changing the theme to a contrasting one. Only if this is not enough, proceed to a global change in the font size in the system.
Frequently asked questions (FAQ)
Why did the font on the keyboard become small after updating Android?
System updates often reset user settings to factory values or change standard themes. Also, the new version of the shell may have different font rendering algorithms. You need to go into the keyboard settings again and adjust the height slider or select a different theme.
Is it possible to increase only the letters without changing the size of the buttons?
In the standard settings Gboard there is no such option: the font size is strictly tied to the button size. However, by choosing a theme with a very bold font style, you will achieve the visual effect of larger letters with the same button size. Third-party keyboards may provide more detailed font settings.
Does increasing the font affect the speed of the Redmi smartphone?
A large font itself does not affect processor performance. However, if you install a "heavy" third-party keyboard with animations for large text, this may slightly increase RAM and battery consumption. System scaling also requires a little more resources to render the interface, but on modern Redmi this is not noticeable.
How to return all the settings back if it becomes inconvenient?
Go to Settings -> Advanced settings -> Language and input. Select your keyboard and reset the height to default. For the system font path: Settings -> Display -> Font size, move the slider to the center. If you installed a third-party keyboard, simply uninstall the application or select Gboard as the main one in the input settings.
