Owners of Xiaomi, Redmi and POCO smartphones often face the need to personalize the interface, and one of the most popular features is the customization of text display. Standard screen settings set by the developers of the MIUI or HyperOS shell are not always suitable for every user, especially if you have small vision problems or you just prefer larger and readable characters. In the messaging application, which is the main communication tool, the comfort of reading directly affects the usability of the gadget in everyday life.
The process of rescaling the font on Android devices can vary depending on the operating system version and the installed model of the messenger application. In the Xiaomi ecosystem, both the system settings of the phone itself and the internal parameters of the particular Messages application are responsible for this. Understanding the difference between these levels of customization will allow you to achieve the perfect result, regardless of whether you are using a standard application or a third-party client for SMS.
In this article, we will look at all the ways to increase or decrease text in correspondence, we will look at the system controls, the specific settings of the MIUI Message application, and also discuss accessibility for people with visual impairments. You will learn not only to change the numbers in the settings, but also to optimize the display of information so that reading news and important notifications is as comfortable as possible and does not cause eye strain.
System settings for displaying text in MIUI and HyperOS
The first and most logical step to resizing the font in all applications, including standard messages, is to address the global settings of the operating system. The MIUI shell and the new HyperOS provide users with powerful tools to personalize visual style. Changing the settings here will affect not only SMS, but also the settings menu, contacts, call log and many other system elements, ensuring uniformity of the interface.
To access these settings, you need to go to the Settings menu, then select the Screen section and find the Text Size item, and you will be given a slider that you can move around from five or seven sizes available, from the smallest to the largest possible size, and the system instantly responds to your actions by showing a preview of what the text will look like on the screen after you apply the settings.
It's important to note that when you select extremely large font values, some interface elements may not be displayed correctly or cropped because they haven't been adapted by application developers to this scale. System font is the basic parameter that dictates the display rules for most programs that don't have their own independent typography settings. So if you want to resize text in messages, and there's no separate setting in the application, this is the main method.
Also worth mentioning is the Enlarged Font feature, which is often activated automatically when selecting the maximum value of the slider, which is specifically designed for users with visual impairments and can change not only the size but also the line spacing, making text more legible. However, for the average user who wants to just zoom in the letters in the SMS, a standard adjustment range is sufficient, without requiring special availability modes.
Set up the font inside the Xiaomi Messages app
Unlike system settings, the application to work with SMS-Messages from Xiaomi (often referred to as MIUI Messages, or simply Messages, can have their own display options that prioritize global ones, allowing users to have a large font in the phone's menu but standard in correspondence, or vice versa. However, in the latest versions of shells, developers often hide these settings, relying on the system standards of Android.
To check for internal settings, open the Messages app and click on the menu button, which is usually represented by three dots in the upper right corner or as a gear. In the list that opens, select Settings, and then look for the section related to the design, appearance or font size itself. If such item is present, you can zoom in text exclusively for dialog windows without affecting the rest of the system.
In some cases, especially on older versions of MIUI, the typeface could be customized into a separate "Decoration" menu within the app itself, where you could choose not only the size but also the style of the font if you installed third-party themes on the phone, and the message interface in such cases was completely rebuilt according to the chosen style, which gave maximum flexibility, but now this functionality is less common due to the unification of the design.
💡
If the application settings do not have the option “Font Size”, then the application is completely dependent on the Android system settings, in which case, change the scale only through the Screen menu in the general settings of the phone.
Note that Google Messages, which is often pre-installed on global versions of Xiaomi smartphones instead of the branded MIUI, also follows system settings. It does not have a separate slider to change the size of text within the dialogue. So if you use this particular messenger, your actions should be focused solely on the global screen calibration described in the previous section of the article.
Using simplicity mode to increase text
One of the most useful but often overlooked features in Xiaomi smartphones is Simple Mode, which was originally designed for older people or users who prefer a simplified interface with large icons and, most importantly for our theme, a larger font in all apps, including messages.
When this mode is activated, the smartphone interface is transformed: the icons on the desktop become huge, unnecessary widgets disappear, and the font in all system applications, including SMS, increases to the maximum readable size. You can switch to this mode through the Settings menu → Simplicity mode, where you need to confirm the action. After rebooting the interface, you will notice dramatic changes in the display of information.
The main advantage of this method is that it doesn't just stretch the font, it restructures the logic of how elements are arranged to make them easier to press and read. Large letters in simplicity mode are displayed even in applications where a normal increase in the system font would not work correctly, and it is the perfect solution for those who do not have a standard text size slider.
⚠️ Note: In simplicity mode, some familiar features and widgets may become inaccessible or hidden.The interface will become more minimalist, which may be unusual for power users, but ideal for focusing on basic tasks such as calls and messages.
Escape from simplicity is as easy as entering: it’s usually enough to press a special button on your desktop or find the appropriate item in the settings. It’s a temporary solution that you can turn on as needed, for example, if you plan to read a long text or send messages in poor light. The flexibility of switching makes this tool a powerful tool for adapting your smartphone to your current needs.
Special features and screen augmentation
For users with severe visual impairments, Android and MIUI have a special feature section, which includes tools that go beyond just changing the font to zoom in on all the contents of the screen, including text in messages, images and controls, and it's not just resizing the font, it's actually zooming in on the image.
Magnification allows you to use gestures to approach any part of the screen. By activating this option in the Settings menu → Advanced Settings → Special features, you can, for example, triple tap on the screen or through a floating button to increase the area of correspondence. The text in the messages will become huge, allowing you to read it without glasses or a magnifier.
Also in this section, there is a frequent feature called "Big Text" or "Very Large Text," which adds additional font size gradations that are not available in the normal screen menu, accessibility settings take precedence over normal user settings, and can override standard application settings. If you want to zoom in as much as possible, you should look for it here.
How to turn on gesture control to increase?
The use of special features can affect the performance of the device, as the system has to constantly recalculate the graphical interface when zooming. However, on modern Xiaomi models with Snapdragon or Dimensity processors, this effect is almost imperceptible.
The impact of design themes on font size
Xiaomi’s ecosystem is famous for its store-themed, which allows you to change not only wallpaper and icons, but also system fonts. Installing a third-party theme can dramatically change the appearance of the Messages app, including size, style and lettering. Some themes are specially designed with a focus on readability and use enlarged default fonts.
To use this method, open the Topics app, go to the font profile or section and select the appropriate option. Once you install the font and reboot the device, the changes will apply to the entire system, including SMS. It is important to choose fonts that support Cyrillic, otherwise you will see squares or question marks instead of Russian letters.
Not all themes correctly display font sizes set in the system settings. Third-party fonts can ignore the scale slider, setting their own size, which can be either larger or smaller than the standard one.
| Type of change | Impact on SMS | Impact on the system | Difficulty |
|---|---|---|---|
| System slider | Direct resizing | Changes everywhere. | Low. |
| Simplicity mode | Maximum increase | Complete restructuring of the interface | Low. |
| Topics and fonts | Depends on the topic. | Changes in style and size | Medium |
| Special opportunities | Scaling up the field | Increasing screen scale | Medium |
If the text text has become unreadable or too small after installing the theme, you can always go back to the standard font in the theme settings or reset the theme to the standard Classic.The Xiaomi theme store allows you to quickly experiment with the look, finding a balance between beauty and functionality.
Solving problems with the display of text in messages
Sometimes users are faced with a situation where changing the settings does not bring the desired result, or the text in the messages is displayed incorrectly: letters bump into each other, cropped or become too pale. In such cases, the problem may lie not in the size, but in the cache of the application or conflict versions.
The first thing you should do is clear the Messages cache. To do this, go to Settings → Apps → All apps, find Messages (or MIUI Message), click Clear and select Clear Cache. This action is safe and will not delete your correspondence, but will reset temporary files that may have caused a display error.
If cleaning the cache didn't help, check for updates for the app itself. A new version that fixes text layout bugs may be available on the Google Play or GetApps store. App updates often solve compatibility issues with a new version of Android or MIUI shell.
☑️ Checklist of diagnostics of problems with text
In rare cases, the problem may be related to a particular message format (e.g, RCS-chatting vs. regular SMS). Switching the chat mode in the app settings can change the input and display interface, which indirectly affects the perceived font size. Try temporarily disabling the chat features to see if the situation changes.
⚠️ Note: When cleaning the application data (not only the cache, but the data) all your SMS-You can delete the messages, and you can be very careful and choose "Clear cache" if you want to keep your correspondence history.
Comparison of standard application and Google Messages
Xiaomi smartphones can pre-installed two different SMS apps: proprietary MIUI Message and standard Google Messages. Users often get confused when trying to customize the font in one app when they are actively using another. Understanding the differences between them will help you choose the right tool to customize.
MIUI Message is deeply integrated into the shell and often responds better to system themes and font settings installed through the theme store.It has a classic Xiaomi design and can have hidden zoom settings depending on the version of MIUI. However, it may be less functional in terms of supporting modern communication protocols.
Google Messages, for its part, follows a strict Material Design philosophy and relies solely on Android system settings. It's almost impossible to find internal font size settings. The key difference is that Google Messages uses a system font without any modifications, which guarantees stability but limits the flexibility of customization without changing global settings.
💡
The choice of SMS app affects the customization methods available: MIUI Message allows more experimentation with themes, and Google Messages provides stability and follows only system settings.
If none of the apps suits you for ease of reading, you can always install a third-party client from Google Play, such as Textra or Chomp SMS. These apps are famous for their powerful customization capabilities, where you can set any font size, color and style regardless of the phone settings.
