Modern Xiaomi smartphones are equipped with high-resolution displays that provide a clear picture, but by default the system text may be too small for comfortable reading. This is especially true for users with impaired vision or those who often read news and books from the device's screen. Standard parameters of the MIUI interface or the new HyperOS shell do not always take into account the individual needs of each owner of the gadget.
Fortunately, the company's engineers have developed flexible personalization tools to adapt the way you display information to your own needs. You can not just zoom in on the letters, but also change the saturation of the letters, which significantly affects the way you perceive content. In this article, we'll take a look at all the ways you can zoom in, including hidden settings and special features.
Proper screen calibration is not only a matter of convenience, but also a matter of eye health. Excessive strain when reading small text leads to fatigue. By studying the instructions below, you can adjust your Redmi or Poco to make interaction with it as comfortable and safe as possible.
Basic text size setting in the menu
The easiest and most obvious way to change the display settings is in the standard system settings menu, which is suitable for most users who just need to make letters bigger without changing other interface parameters. The algorithm of actions is the same for all current firmware versions, whether it is the old MIUI 12 or the latest HyperOS.
First, you need to open the main application menu and find the gear icon, which is the input point to the system partition of device management. Next, follow the Settings → Screen → Text Size path. In some versions of the shell, the path may be slightly different, for example, through the Additional section, but the logic remains the same.
And you'll see a slider that adjusts the scale on the screen that opens, and if you move it to the right, you'll see the size of the letters change in real time at the top of the display, and it's important to balance that so that the text is readable, but you can put enough information on the screen.
- 🔍 Open the Settings app on the main screen.
- 📱 Go to the screen or display section».
- 📏 Find the item "Size of text" slider.
- ✅ Click OK or go back to save the changes.
It is worth noting that changing this setting affects most system applications and third-party programs that support dynamic scaling, but in some utilities, the font size may remain the same if developers have rigidly set fixed values in the application code.
Adjusting font boldness for better readability
Often the problem is not so much the size of the symbols as their subtlety. AMOLED-In the case of the screens that are equipped with flagship models Xiaomi 13 or Xiaomi 14, thin fonts can look pale and merge with the background in bright light.
This feature is on the same menu as the size adjustment, and right below the scale slider, you usually have the option "Bold Text" or "Bold Text," and activating this switch makes the letter lines thicker and contrast, which is especially useful for people with farsightedness or astigmatism.
⚠️ Note: Enabling bold can cause long words to move to a new line earlier than usual, which will change the layout of the text in some applications.
Using bold marks also helps you better distinguish between symbols in the sun when glare interferes with reading. This software solution works more effectively than simply increasing the brightness of a display that lands the battery faster. Experiment with a combination of size and fat to achieve the perfect result.
It's important to understand that bold print consumes a little more GPU resources when rendering the interface, although on modern Snapdragon or MediaTek chips this effect is imperceptible. Budget model users may notice a minimal change in the smoothness of animations, but in everyday use this is rarely a problem.
Use of augmentation mode for visually impaired
For users with significant visual impairments, standard magnification may not be enough. In the arsenal of the Android operating system, which runs the Redmi and Poco phones, there is a special zoom mode, which allows you to temporarily scale any part of the screen with gestures, like using a magnifier.
To activate this feature, go to Settings → Advanced Settings → Special Options → Vision → Enlargement. You can choose zoom in by area or zoom in by whole screen. In the first case, you pinpoint a rectangle that you want to zoom in on, in the second, you zoom in on the entire interface at once.
This tool is indispensable for looking at small details in photos, reading small text in the menu of banking applications or filling out complex forms, control is through screen gestures that can be customized for yourself, and adjusting response speed and type of control is available.
- 👁️ Enable the “Increase shortcut” switch for quick access.
- 🖐️ Use triple touch of the screen to activate the magnifying glass.
- 📐 Choose between scaling the entire area or part of the screen.
- ⚙️ Set up the sensitivity of gestures in the menu of special features.
Activating the magnification mode does not require rebooting the device and takes effect instantly. It is a temporary solution that only turns on when it is really necessary. The rest of the time the interface runs in standard mode without distorting the picture.

Size adjustment of interface elements in special features
In addition to text, Xiaomi smartphones can scale other interface elements: buttons, app icons, input fields, a feature called Screen Element Size, which is on the same menu as the font settings, and allows you to make all objects on the display larger, while maintaining proportions.
Changing this parameter is especially important for large-diagonal models, where the distance between the elements can be large for the user's fingers, increasing the scale of the elements makes navigation more convenient and reduces the likelihood of erroneous clicks, which is critical for older people.
| Parameter | Impact on the system | Recommended value |
|---|---|---|
| Small one. | Maximum information on the screen, small elements | For users with good vision |
| Standard. | Balance between capacity and readability | Factory default setting |
| Big one. | Increased buttons and indentations, less content | For comfortable work with one hand |
| Huge. | Maximum size of elements, simplified appearance | For users with impaired vision |
When switching to large interface elements, some applications may not display correctly if they are not adapted to different pixel densities (DPIs), in which case it may be necessary to restart the application or change the orientation of the screen to redraw the interface.
Remember, the increase in screen features means fewer widgets and icons fit on your desktop, a trade-off between usability and the information capacity of your workspace, and it's recommended that you find a middle ground that works for you.
☑️ Checking the display settings
Change DPI through Engineering Menu and ADB
For advanced users who don't have enough standard settings, it's possible to manually change the dot-per-inch density (DPI) so that you can make the font and interface as large as possible or microscopically small, and this requires caution.
To access these settings, you need to activate the developer mode. You can do this by going to Settings → About Phone and quickly clicking 7-10 times on the “MIUI Version” or “OS Version”. After the message “You became a developer”, a new section “Additional” → “For developers” will appear in the menu.
Inside the developer menu, you need to find the "Minimum Width" (or "Smallest Width") item. The default value is usually 360-400 dp. Reducing that number (like 320) will make all the elements larger. Increasing the number (to 500 or higher) will make the interface very shallow.
adb shell wm density 320An alternative is to use the ADB command line through a computer, and by connecting the phone to a USB debugging device, you can type the command above, which gives you more flexibility, but requires a PC and drivers installed.
⚠️ Attention: Set too low a value DPI (less than 200) may cause the interface to become unreadable and some system buttons to disappear outside the screen. ADB.
Experimenting with DPI is only worth it if you understand the risks, and for most users, standard sliders are enough on the screen menu, but it's indispensable to create a unique visual style or adapt to specific tasks.
💡
Write down the current DPI before you change! If the interface becomes unreadable, you can't go back through the menu. The best way is to take a picture of the settings screen before you make the changes.
Features of display in applications and browsers
It’s important to understand that the system font settings don’t always apply to all apps the same way. Many modern programs like Telegram, WhatsApp, or Chrome have their own internal text size settings that take precedence over system ones.
For example, in Chrome on Android, you can set the page scale separately, and you can go to your browser settings, select the "Special Features" section, and set the desired value with a "Scaling Text" slider, which allows you to read the sites comfortably without enlarging the font throughout the phone.
In instant messengers, settings are often in the chat room or the data and memory section, where you can choose the size of the message font regardless of the rest of the system, which is convenient if you like the small menu interface, but the text of the correspondence should be large.
- 🌐 In the browser, use the “Mobile version” function for better zooming.
- 💬 In messengers, look for settings in the “Chats” section».
- 📚 In reading apps (Kindle, Bookmate), the font size changes in the book menu.
- 📱 Some launchers allow you to change the size of the icon signatures separately.
If in a particular application the text remains small despite all the settings, perhaps the developer did not put this option in place, in which case only the zoom or magnifier mode described in the section on special features will help.
It’s also worth mentioning the Classic theme or other Themes themes that can force you to specify your font styles. If you’ve set a third-party theme and the font has become unreadable, try changing the theme to a standard one or removing the font through the Themes app.
💡
System font settings are basic, but many applications have their own priority settings that need to be changed separately within each application.
