Xiaomi and Redmi smartphone owners often face the challenge of adapting the interface to their visual preferences or vision. Standard font settings can seem too small, especially on high-resolution screens where pixel density is high. Fortunately, the MIUI shell and the new HyperOS provide flexible tools to personalize text display.
Changing the size of letters affects not only system menus, but also the work in messengers, browsers and social networks, which significantly improves the comfort of the device for the elderly or visually impaired users. In this article, we will discuss in detail all available methods of text scaling, including the hidden features of the engineering menu.
The customization process does not require a superuser (Root) license, and it takes a few minutes, and you can change not only the size, but also the style of the pattern, and also include special modes to reduce the load on the eyes. Let's start to look at all the options available in detail.
Standard font size settings in MIUI
The basic way to change text display settings is built into the default system, so you have to go to the main settings menu and select the Screen section to access them. In some firmware versions, this item may be called Display or be inside the Advanced Settings category.
In the window that opens, you'll see a slider that adjusts the size of the font, and if you move it left or right, you can instantly measure the changes in real time, and the system automatically applies the new scale to all the interface elements that are supported, including the application headers and the text in the settings.
⚠️ Note: With maximum font enlargement, some interface elements may be cropped or overlapped, as the grid of icons will remain the same.
In addition to size, the same menu often offers a fatty spelling setting, so you can choose the regular, Medium or Bold style, which will make the text more contrasting and readable without changing its dimensions, which is especially useful for people who wear glasses.
Use of the "Reading" mode and dark topics
To reduce eye fatigue, Xiaomi has introduced a special Read Mode mode, which not only changes color reproduction, but also optimizes the contrast of text to make it clearer, and you can activate this feature through the notification curtain or in the screen settings.
In the advanced reading settings, the paper effect feature is available, which gives the background a yellowish hue by simulating an e-book, which allows you to work with text without cutting in the eyes, and the combination of large print and warm backlight spectrum is ideal for evening use of a smartphone.
Also worth considering is the use of Dark Theme: In low light conditions, white text on a black background is more easily perceived by the eye than black on white. In MIUI, you can set the dark theme to automatically turn on on on a schedule or depending on the time of day.
- 📱 Go to Settings. → Screen. → Dark theme for activation.
- 🌙 Set up an on schedule so your eyes don’t get tired at night.
- 🎨 Use adaptive wallpaper that changes color depending on the topic.
Some third-party Themes themes have their own, larger, and contrasting fonts that redefine system settings. If standard methods don't suit you, finding the right theme can be an effective solution.
Interface Element Scaling (DPI)
If a standard slider isn't enough, you can change the overall screen scale, known as DPI (Dot Per Inch), which affects not only the text, but also the size of icons, buttons and spaces between elements, and change the DPI to make the interface really huge or as compact as possible.
To access this feature, you need to activate the developer menu. Go to Settings → About Phone and quickly click 7 times on the MIUI Version (or OS Version). Once you have the message "You became a developer", go back and find the new section Advanced Settings → For developers.
How to find the "minimum width" item?
In the list of parameters, find Minimum width (or Smallest width). The default value is usually 360-392 dpi depending on the model. Reducing this number (for example, to 320) will increase all elements on the screen, including fonts. Increasing the number, on the contrary, will reduce the interface.
⚠️ Note: Do not set extremely low values DPI (less than 300), as this can make the interface unreadable and require resetting the phone settings to recover.
This is the most powerful zooming tool, but it takes care to change the logic of how you build the interface, so some applications may not display correctly, showing too little information on the screen or requiring constant scrolling.
Special treatment for older persons
Xiaomi has a separate mode designed specifically for the older generation, which dramatically changes the logic of the smartphone, increasing not only fonts, but also icons, and simplifying navigation. → Special facilities → Regime for the elderly.
When this mode is activated, the desktop is transformed: huge widgets of time, weather and large labels of major applications appear, the font in the menu and contacts becomes as large and contrasting as possible, eliminating the need to squint.
| Parameter | Standard regimen | Regime for the elderly |
|---|---|---|
| Size of icons | Standard. | Enlarged (XL) |
| Font menu | Customizable | Maximum |
| Desktop structure | Application grid | Large widgets |
| Loudness of the call | Normal. | Increased (default) |
It is important to note that in this mode, some complex functions and applications can be hidden or simplified, so as not to confuse the user, exiting the mode is done by long pressing the power button or through settings, if access is saved.
☑️ Checking settings for the elderly
Set up the font in the browser and applications
Often users want to zoom in text only when reading news or books, leaving the system interface unchanged. Most modern browsers, such as Chrome, UC Browser or the built-in Mi Browser, have their own page zooming settings.
In Google Chrome, you have to click three dots in the corner, select Settings, then go to Special Opportunities, and there's a page scale slider that forcibly enlarges all the elements of a website, and it doesn't change the system font, but it solves the problem of reading texts on the Internet.
Book-reading apps like FBReader or Moon+ Reader allow you to flexibly customize the font regardless of the system. You can choose any typeface from your phone's memory, change line spacing and fields, creating the perfect reading environment.
- 📖 In the browser settings, look for the item 'Scale' or 'Zoom'.
- 📱 In reading apps, use the 'Aa' menu to customize the font.
- 🌐 Some sites allow you to change the size of the text through the menu of the page itself.
There are also special Google Play augmentation apps that work like a magnifier, and they use the phone's camera to zoom in on paper or other devices, which can be useful in certain situations.
Installation of third-party fonts through the Topics app
Themes store on Xiaomi is not just about wallpaper and icons, but you can find thousands of variants of the fonts section, many of which are larger and bolder than the standard Roboto system font by default.
To install, go to the Themes app, switch to the Font tab, and select your favorite option. Pay attention to the preview: often the description indicates that the font has a Bold (grand) mark or increased proportions of letters.
💡
Many paid fonts are available for free by doing simple tasks inside the 'Themes' app ('Coins' or 'Assignments' section) and this will allow you to try premium type at no cost.
Once you have applied the font, the changes will take effect immediately, and if you don't like the new font or find it difficult to read, you can always replace it back with the standard font in the same menu by selecting the default font.
Be careful with exotic fonts, as they may not have Cyrillic characters or special signs. Always check the display of the Russian alphabet before long-term use.
