Modern Xiaomi, Redmi and POCO smartphones have great displays, but standard MIUI or HyperOS interface settings are not always ideal for all users. Often device owners are faced with a situation where the text of incoming messages is too small, which makes them squint or bring the screen to the eyes. Especially relevant is the question of how to change the font size in SMS in Xiaomi, for people with impaired vision or simply prefer large typography for quick reading.
Fortunately, the Chinese-made Android operating system provides flexible personalization tools. You can customize not only the overall text size throughout the system, but also the specific display parameters in individual applications. In this article, we will take a look at all the scaling methods available, from basic settings to the hidden capabilities of the engineering menu.
It's important to understand that the interface may vary slightly depending on the firmware version, but the logic of the menu remains the same for most current models, and we'll look at the nuances for different versions of MIUI and the new HyperOS, so that each user can find a solution to their problem.
Global settings for displaying text in the system
The first and most obvious step to take is to change the system settings of the font. In Xiaomi’s ecosystem, font settings affect most applications, including the standard Messages app, a basic level from which to start setting up if you’re concerned about small text.
To access these options, you need to open the main settings menu of your smartphone. Find a section that is usually called Screen or Display. Inside this section, you have key visual content controls, and that's where you zoom in on the interface.
💡
Before changing the settings, take a screenshot of the current settings to quickly return everything as it was.
Changing the system font affects not only SMS, but also the settings menu, contacts and browser. So as you zoom in, make sure that text doesn't bump into control buttons or other important interface elements. The balance between readability and ergonomics is key.
- 📱 Open “Settings” and go to the “Screen” section».
- 🔍 Find the item “Text size and display” or similar.
- 📏 Move the slider to the right to increase the font to a comfortable level.
- ✅ Click “Apply” or just exit the menu to save.
It's worth noting that new versions of the HyperOS shell have improved the font rendering algorithms, made the text clearer even when you zoom in, making reading long messages much more enjoyable. If you don't have enough standard values, move on to the next section.
Use of the “big text” regime for the elderly
Xiaomi has a feature that was originally designed for people with poor eyesight, but is useful to anyone who wants to see the text as large as possible, often called “Mode for the elderly” or “Simple Mode”, but its impact on the font size in SMS is huge.
Activating this mode dramatically changes the interface of the desktop and applications, icons become huge, and the font in messages increases to the limit values available in the system, which is the maximum increase that a smartphone can offer without using third-party programs.
⚠️ Warning: Enabling a simple mode can change the layout of widgets and icons on the desktop.Be prepared for the fact that the usual interface will temporarily disappear.
To activate this feature, go to the settings and search for settings, type the word "Mode." Select "Mode for the elderly" or "Simple Mode." Once turned on, the phone will prompt you to confirm the action, as the appearance of the system will change.
In this mode, navigation is simplified, and the font size in the message app becomes really big, ideal for those who do not want to constantly strain their eyes, and you can return everything through the same menu item or through the theme settings.
Set up the font through the “Themes” app
A unique feature of the MIUI and HyperOS shell is the powerful Themes app, which allows you to change not only wallpaper and icons, but also system fonts, and many users are unaware that installing a new font can solve the problem of readability of SMS.
There are thousands of different fonts available in the theme store, including options with increased base character size or bolder marking, and bold font visually perceived as larger, even if its physical size in pixels has not changed.
To find the right font, open the Themes app, go to the profile (human icon) and select Fonts. You can search for "Large", "Big" or simply choose a visually appropriate option. Once you install the font, the changes will apply to the entire system, including SMS.
- 🎨 Launch the “Themes” app on your smartphone.
- 🔤 Go to the “Fonts” section via the bottom menu or profile.
- 📥 Download and use a font with large or bold characters.
- 🔄 Restart the device to display correctly in all applications.
Some fonts may be paid, but free options with good readability abound too. Experiment with different styles to find the one that works best for your eyes and reading habits.
Specific settings of the “Messages” application
Unlike some other vendors, Xiaomi does not always display a font size slider in a standard SMS app, but the settings may vary depending on the version of the app (Google Messages or MIUI Messages).
If you use a standard Google app (often found on global versions), there may not be a separate font size setting within the app itself, but it is completely subject to the system settings we talked about at the beginning of this article, in which case the system slider is the only lever.
If you use a Xiaomi app, try going to the settings three dots in the corner of the screen, and sometimes you have a "Display Settings" or "Font Size" option that works independently of the system, which is rare, but it's worth checking.
| Type of application | System dependency | Where to look for settings | Possibility of change |
|---|---|---|---|
| Google Messages | Complete. | Phone settings | Only through the system. |
| MIUI Messages | Partial | Inside the app | Maybe in older versions. |
| Third-party (Textra) | No. | Application settings | Full independence |
If the built-in tools don’t work, it’s logical to turn to third-party solutions, and the Android app market offers many alternatives to the standard caller and SMS client.
Alternative applications for SMS with flexible settings
When standard methods are exhausted, third-party apps from Google Play come to the rescue. They often provide much more freedom in customizing the interface, allowing you to change the font size, color and style of messages regardless of the system.
One of the most popular solutions is Textra SMS, which is famous for its light weight and a lot of customization, and in this app, you can set your font size for incoming and outgoing messages separately, and it's an independent zoom that's very convenient.
☑️ Selection of an alternative application
Another great option is QKSMS, which is an open source app that is completely free and doesn't contain ads, and it allows you to fine-tune typography, making it comfortable to read correspondence even on small screens of budget smartphones.
⚠️ Note: When installing a third-party SMS application, you will need to give it permission to work with messages and contacts.
Using alternative software is often the only solution for owners of older Xiaomi models who haven’t received any interface updates.You get a modern and convenient tool to communicate without having to change your phone.
Additional Accessibility Functions (Accessibility)
And underneath the Android settings, there's a powerful Accessibility section, which is a tool that helps people with disabilities, but it's also useful in normal situations, and zoom in and lets you zoom in with your fingers.
By activating this feature, you can triple tap on the screen to zoom in on any area, including text, which doesn't change the font size all the time, but allows you to quickly read the small detail. This time zoom in works like a magnifier.
And this section also has a setting called "Size of UI Elements," which affects how much content is placed on the screen, and by reducing the density of the elements, you automatically increase the font size and indentations in applications, including SMS.
How to Enable Triple Press Increase
Don't ignore these settings, even if you don't have official vision restrictions, because they're designed for user comfort and can be a lifeline when you need to read a message in very small print.
Comparison of settings in MIUI and HyperOS
With the release of the new HyperOS operating system, many Xiaomi users noticed a change in menu logic. Although the basic principles remained the same, the location of some items may have shifted, and it is important to consider these differences when looking for settings.
In MIUI 12-14, the font settings were most often in the "Additional" section inside the screen menu. In HyperOS, the structure became flatter and more logical, the items were brought to the first level of nesting, which makes it easier to search, but can confuse accustomed users.
In addition, the new shell has improved the work with dynamic font, the system itself suggests increasing the size of the text if you find that the user often zooms in, a smart feature that is based on the analysis of user behavior.
- 🆚 V MIUI The path is often longer: Settings -> Screen -> Additionally.
- 🚀 In HyperOS, the path is shorter: Settings -> Screen -> Size of text.
- 🧠 HyperOS smarter offers changes based on habits.
- 🎨 Visual font styles in HyperOS are more modern.
Regardless of your firmware version, the goal remains to make smartphone usage more comfortable, and understanding the differences between software versions will help you find the right option faster.
💡
The firmware version (MIUI or HyperOS) only affects the location of menu items, but not the ability to change the font itself.
