Xiaomi and Redmi smartphone owners often face the need to adapt the interface to their needs. Standard text size can be too small for people with low vision or simply uncomfortable in bright sunlight. Fortunately, the Android operating system in the shell of MIUI or HyperOS provides flexible tools to personalize the display of information.
In this article, we will discuss in detail all the available ways to increase the font on the Redmi Note series. You will learn not only about the basic settings, but also about the hidden features of the system that allow you to make the use of the gadget as comfortable as possible.
Many users don't realize that changing character sizes doesn't affect screen resolution or picture quality, but it's a software adjustment that's safe for the device, and calibrating text correctly is the first step to ergonomically using your smartphone in your everyday life.
Basic text display settings in MIUI and HyperOS
The easiest and most common way to resize characters is in the standard settings menu, which is suitable for most models, including the Redmi Note 8, Note 9, Note 10 and newer versions.
First, you have to open the main menu and find the gear icon, and then you go through the Screen (or Display) section, and that's where the basic visualization parameters, including brightness, refresh rate, and of course font size, are concentrated.
In the menu that opens, you'll see a slider that's labeled Size of Text, and if you move it to the right, you'll see in real time how the characters' display changes in the preview from above, and you can get the optimal value without any further guesswork.
It is worth noting that changing this setting affects system applications, settings menus and most third-party programs developed in compliance with Android standards. However, some applications may ignore system settings and use their own scale.
⚠️ Note: With maximum font enlargement, some interface elements may crop or overlap, especially in fixed layout applications.
Once you've chosen a convenient scale, just go back to the home screen, the system automatically saves the selected settings, and if you don't like the result, you can always repeat the procedure and choose a different value for the slider.
Use of augmentation mode for visually impaired
For users with severe visual impairments, standard font zoom may not be enough, and a special accessibility feature called Magnification comes to the rescue, which works like a virtual magnifier, allowing any part of the screen to be zoomed in at the click of your fingers.
You can activate this function through the Settings menu → Additional settings → Special features. In the list of tools, you need to find the item Increase and move the switch to the active position. Here you can choose the activation mode: volume button, triple touch the screen or through a floating button.
Triple-touch mode is the most convenient for everyday use, and once it's turned on, you can zoom in on any part of the screen by tapping the display three times quickly, and it works even in your browser, gallery, and video players.
- 🔍 Triple touch activates the magnifying glass at the point of pressing.
- 👆 Two fingers allow you to move around the enlarged area.
- 🔎 A pinch with two fingers adjusts the degree of magnification regardless of the system font.
- ⚙️ Sensitivity settings are available in the special features menu.
It's important to understand the difference between system font and screen zoom, so if the first one changes the size of text across the entire interface globally, the second one is a temporary tool for looking at content in detail, and using both methods simultaneously produces the best result.
💡
For quick access to accessibility features, add the Special Features widget to your desktop or set up a power button call.
The feature is especially useful when viewing photos with fine details or reading documents in PDF format, where text zooming is often blocked by the app developer.
Size setting of interface elements and DPI
Beyond text, the overall size of the interface elements is also influencing perception, and Xiaomi smartphones have the ability to scale up the display of all the contents of the screen, which is useful if, even in large print, buttons and icons seem too small.
You can find this setting by Settings → Screen → Element Size. There's also a slider that moves the scale of the buttons, input fields and indentations, which creates a feeling of a larger and more spacious interface.
For advanced users, it is possible to change the DPI (dots per inch) setting through the developer menu, which allows for extreme magnification, but requires caution, as it can disrupt the layout of some applications.
adb shell wm density 320In the command 320 above, this is an example of density. Standard values usually range from 360 to 480 depending on the Redmi Note model. Decreasing the number increases all the elements, increasing increases it decreases.
| Parameter | Standard value | For large text | Impact on the system |
|---|---|---|---|
| Size of text | Medium. | Huge. | Just symbols. |
| Size of elements | By default. | Maximum | Buttons and indentations |
| DPI (density) | ~400-440 | ~280-320 | The interface. |
| Bold text | Off | On | Readability |
Change of change DPI through ADB-The command is a powerful tool, but not recommended for inexperienced users. A mistake in meaning can make the interface unreadable, requiring a reset setting.
Including bold text for better readability
Another effective way to improve the perception of information is to enable Fat Text mode, which makes the characters more saturated and contrasting, which makes it much easier to read in poor light or in bright sun.
This setting is in the same menu as the font size: Settings → Screen → Fat text. Once activated, you will need to restart the device so that the changes apply to all system components.
The font is particularly useful for AMOLED-The black color on these displays looks deep, and white bold letters create a great contrast, reducing eye fatigue.
⚠️ Warning: Enabling bold text can slightly increase the energy consumption of the display, as it paints over a large area of pixels.
Some users have noted that when this option is enabled, some apps may look “too thick” and merge, in which case it is recommended to experiment with a combination of plain and bold.
☑️ Checking screen settings
The use of bold font in combination with the increased size gives a synergistic effect, making the smartphone convenient for people with farsightedness or just for comfortable reading long articles.
Features of increasing the font in the browser and applications
System settings don't always apply to the content of web browsers or specific applications, such as Chrome or MIUI Browser, which does the page zooming separately, so that the layout of sites does not "go" in the global changes in the system.
In Chrome, you go to the menu (three dots in the corner), select Settings → Special Features. There you will find the Scaling Text slider, which allows you to zoom in the font only inside the browser tabs without affecting the rest of the phone.
Book-reading apps like MI Reader or FBReader also have their own font settings, usually in the settings menu of a particular book or in the general settings of an application, which allows you to read in small print in some books and large in others.
- 📱 On social media, the scale is often tweaked by two fingers.
- 📖 In the reader you can choose a specific font (for example, Arial or Times New Roman).
- 🌐 Browsers keep the scale for each site separately.
- ⚙️ Some launchers allow you to increase the size of icons and signatures on the desktop.
Understanding where the scale is managed is a great deal of confusion, because if you zoom in on the system but it's still small in the browser, it's normal behavior that requires a separate setup within the application.
Why does the font not change in some applications?
Solving problems with layout after changing the font
Sometimes, too much font can cause text to be removed from the designated fields, so OK or Cancel buttons can be cut, and important messages can become unreadable, and in such cases, you need to find a balance between size and functionality.
If the interface is so “got” that you can’t get into the settings menu, try using Google Assistant voice control: say “Open Settings”, “Reduce font” (if supported by plugins), or just navigate with your voice.
In extreme cases, if access to the menu is lost completely, you can reset special features through safe mode or hardware reset, although the latter is recommended only in desperate situations.
The best solution is to gradually increase the parameters. Don't put the slider at the maximum right away. Add two or two divisions, check the main applications, and then continue the setup.
⚠️ Note: It is not recommended to change system font files (replace.ttf files at the root of the system) without having SuperUser rights and a full backup, as this can lead to a cyclic reboot (bootloop).
Modern HyperOS shells have become smarter at handling large fonts by automatically moving lines and adapting buttons, but older versions of MIUI have seen more layout problems.
💡
The main rule of setting is to enlarge the font as long as the interface remains functional and all buttons are available for clicking.
