How to increase the font on the keyboard and in the Xiaomi Redmi system

Many Xiaomi and Redmi smartphone users face a situation where standard text size seems too small, especially for people with low vision or when using devices with high-resolution screens, where the density of pixels makes letters microscopic, a problem often arises not only in the menu, but also in typing, when the keyboard displays barely distinguishable characters.

Fortunately, the MIUI shell and the newer HyperOS provide advanced options for personalizing the interface. You can change not only the size of the system font, but also the scale of the entire image, which automatically increases controls, including the keyboard. In this article, we will break down all the available customization methods, from simple switches to hidden engineering menus.

Before we get to the tricky steps, it's worth noting that changing display parameters doesn't affect the performance of the device. However, too much magnification can cause some interface elements to crop or overlap, so it's important to find a balance between readability and usability.

Basic font size setting in MIUI

The easiest and safest way to make text bigger is to use standard system settings, which are suitable for all Xiaomi Redmi Note, Poco and flagship series, and the changes take effect instantly and affect most system applications and menus.

First, you have to open the main settings menu, find the interface interface interface interface interface section, the path may vary slightly depending on the shell version, but the logic remains the same for the entire manufacturer ecosystem, text size is regulated by a slider that allows you to choose one of five preset options.

If you don't have the standard five sizes, there's a secret function, and there's a default button in the text size selection menu, or a gear icon (depending on the MIUI version), and if you click on it, you'll be taken to an extended menu where the slider becomes continuous, and you can set a custom font size that's not possible in standard mode.

⚠️ Note: When setting extremely large text values, the names of some applications may not fit under the icons on the desktop.

Once you have set up the base font, it is recommended to restart the device so that the changes apply to all running background processes, which ensures that even those applications that cache display parameters update their interface.

Changing the screen to increase the keyboard

Users often confuse font size with the overall interface scale. If the keyboard on Xiaomi seems small, the problem may not be the font, but the density of elements per inch (DPI). The increase in screen scale makes everything: buttons, input fields and the letters themselves on the virtual keyboard larger.

To access this feature, go to the settings menu and look for Advanced Settings. In some firmware versions, it may simply be called "Advanced." Here we're interested in the setting related to the size of the interface elements. Unlike the font setting, here the change affects the geometry of the buttons.

It's important to understand the difference between scaling and resolution. Scaling just stretches the picture, making it larger, but less detailed per unit area. Resolution determines the number of pixels. For the elderly or those with poor eyesight, zooming is the most effective solution.

There is also the possibility of fine-tuning through the developer menu, which will be discussed below. However, standard means can be achieved to increase the Gboard keyboard or the standard MIUI keyboard to a comfortable size. Note that with a strong increase, part of the keyboard can overlap the contents of the chat.

Use of the Developer Menu

For advanced users who don’t have enough standard settings, the MIUI shell provides access to hidden settings. The developer menu allows you to change the minimum screen width (Smallest Width), which directly affects how much content is placed on the screen and how big it is.

To activate this mode, you need to go to About Phone and quickly click on MIUI seven times. Once you become a developer, a new option will appear in the settings menu, and you need to find an option, often called Minimum Width or Smallest Width.

The default value is usually around 360-392 dp (depending on the model). Reducing this number (e.g. to 320 or 300) will make all elements, including text and keyboard, significantly larger. Be careful: setting a value too low (less than 200) can make the interface unusable, and you have to reset the settings.

This is the most powerful customization tool, which allows you to bypass the manufacturer's restrictions on standard users, but remember that some applications may not display correctly at non-standard DPI values.

Configure a specific Gboard and MIUI keyboard

Special attention should be paid to the configuration of the keyboard application itself. Often, the system font settings do not affect the height of the buttons or the size of the letters on the keys as the user would like, in which case you need to get into the settings of the input application itself.

For the standard Gboard (which is often on global versions) or MIUI Keyboard (in Chinese versions), the algorithm of actions is similar: you need to open any application to type in, call the keyboard and click on the settings icon (cog).

In the keyboard settings menu, look for Preferences or Settings, and there's often a slider called Keyboard Height or Keyboard Size, and moving that slider changes the physical size of the input area, which automatically makes the letters larger.

You can also use a high contrast theme in your keyboard settings, or you can choose a font with clearer, bolder letters, which makes reading visually easier, even if the physical size of the character hasn't changed dramatically.

Functions of special opportunities for visually impaired

Android and MIUI have powerful tools designed specifically for visually impaired people that allow you to increase not static font size, but to apply a temporary magnification (magnification) or invert colors for better readability.

Magnification works like a magnifier, and by activating it, you can triple tap the screen or use volume buttons (depending on the settings) to increase any part of the screen, including the text on the keyboard, to a giant size, which is convenient for a single entry of a complex password or reading small text.

Another useful option is Visibility Improver, which allows you to force text to be bold, add contrasting bezels around buttons, and invert colors, and these settings are located in the Special Opportunities section -> Visibility Improver.

💡

Use voice input if the keyboard still seems uncomfortable.Pick the microphone and just dictate the message - this is often faster and doesn't require looking at small letters.

Don't ignore High-Contrast Text, which changes the background color of the letters below, making them as visible as possible, and this is especially true in bright sunlight, when the screen is shining and the usual brightness settings don't help.

Solving and resolving problems

Sometimes, after a system update or third-party theme is installed, the font settings may reset or behave incorrectly. For example, in some applications, the text remains small despite global changes, due to the fact that application developers can rigidly set their display parameters.

If you have a third-party theme, it can override system fonts, which can help to return to the standard theme of "Classic" or "No Limits" in the "Themes" app, and after changing the theme of the text size setting, you often need to re-post.

⚠️ Warning: Installing themes from unverified sources may cause some system labels to become unreadable or disappear altogether.

Also worth mentioning is the problem with the porridge on the screen, where as the text gets bigger, the lines start crawling on top of each other, in which case it helps to change the orientation of the screen or to turn on the "Simple Mode" (Mode for the elderly), which rebuilt the entire interface into large elements.

💡

The comprehensive use of font settings, DPI scale and keyboard height gives the best result for people with poor vision.
