Smartphone owners often face a situation where standard text size on the screen is not enough for comfortable reading, which may be due to age-related changes in vision, the features of the display of a particular model, or simply personal preferences of the user. The shells of MIUI and the new HyperOS, which are installed on Xiaomi, Redmi and POCO devices, provide flexible tools for customizing the interface, allowing you to adapt the picture to any needs.
Changing the scale of interface elements is not just a cosmetic procedure, but an important accessibility feature. Correctly configured font reduces eye strain and speeds up interaction with the device as a whole. However, many users are limited to standard sliders, not knowing about the existence of deeper system settings that allow you to change the pixel density (DPI) and forcefully scale individual elements.
In this article, we will go into detail all the ways to increase or decrease text elements, we will look at the standard tools of the system, hidden developer menus and specialized applications, you will learn how to make text readable on any screen, whether it is a compact smartphone or a device with a large diagonal.
Basic setting through the display menu
The easiest and safest way to resize a font on Xiaomi is to use the built-in settings, which do not require superuser rights and are completely reversible at any time, so you need to go to the main settings menu of your device and find the section that controls the appearance of the interface.
Depending on the version of the shell installed (MIUI 12, 13, 14 or HyperOS), the path to the desired parameters may vary slightly, but the logic remains the same. You need to find the "Screen" or "Display" item, where the basic visualization parameters are hidden, and this is where the slider is located, regulating the scale of text throughout the system.
Once you move the slider, the changes take effect instantly, you can choose from five preset sizes or customize your individual value. Note that enlarging the font can cause some interface elements to display incorrectly or to go beyond the screen in certain applications.
- 📱 Open “Settings” and go to the “Screen” section».
- 🔍 Find the “Text Size” item and click on it.
- 📏 Move the slider left or right to select the desired scale.
- ✅ Click OK or just go back to save the changes.
💡
If after changing the text size, the names of applications on the desktop have become too large and do not fit under the icons, try changing the size of the desktop grid in the Wallpaper → Settings → More settings.
It is important to understand that standard configuration affects mainly system fonts and supported applications. In some third-party programs, whose developers have rigidly set display parameters, changes may not appear, in which case deeper intervention is required.
Use of Developer Mode and DPI
For advanced users who lack the capabilities of a standard menu, there is an option to change the minimum width (DPI), which determines how many pixels per inch of the screen, and directly affects the density of the display of all elements, including text, icons and indentations.
To access these settings, you need to activate the hidden Developer Menu by repeatedly clicking on the build number in the About section, and after activating, a new option will appear in the main settings menu where you can find the Minimum Width option.
⚠️ Attention: Change of value DPI It can cause the interface to be displayed incorrectly, even to the point of being completely unreadable. Remember the original value before making changes so you can get it back!
The default value varies depending on the device model. For standard smartphones, it is usually 360-400 dpi, for high-resolution devices, 480 dpi and higher. Reducing this number makes all elements larger and increasing smaller. Change the value in small steps, for example, by 20-30 units, checking the result after each action.
- 🔧 Go to "Settings» → «About the phone and 7 times click on the "Version" MIUI».
- 🚀 Go to "Additional» → «For developers».
- 📉 Find the "Minimum Width" option (or "Smallest Width).
- 📝 Enter a new value (normally 360, try 320 for enlargement).
Using this method, you can achieve the same result as a tablet mode, if you reduce the DPI very much, or make the interface as large as possible for people with poor vision, but it is worth remembering that some applications may not support non-standard resolutions and will look stretched or with cropped edges.
☑️ Checking before change DPI
Set up the font in reading mode and themes
The MIUI shell offers additional tools for those who read a lot from the screen, and the built-in Reading app and theme store allows not only resize but also completely transform the spelling, which is especially true for users who want to personalize their device.
The Reading app (often built into a browser or a separate bookshelf) has its own font regulator, which works independently of system settings and only affects the way text is displayed inside the app, which is convenient because it allows you to keep the system interface compact and books read in large print.
The Themes store provides access to thousands of fonts, some of which seem larger than standard fonts because of their typing, and if you install one, you can visually zoom in text across the entire interface without changing the system's zoom parameters, and it's a safe method that doesn't break the layout of the applications.
To install the new font, go to the Topics app, select the Fonts tab and browse directory. Once you download and use the font, it will replace the system Roboto or MiSans. Please note that some fonts may not support Cyrillic, so check for Russian letters in the preview before installing.
- 📚 Open the Reading or Mi Video app for local text settings.
- 🎨 Go to the “Themes” app to change the style of the font.
- 🔤 In the search for themes, enter “font” or “font” to search for new shapes.
- ⬇️ Download and apply your favorite option, confirming the reboot.

Special opportunities for the visually impaired
Android and MIUI have a powerful special feature section for people with disabilities, but it's useful for everyone, and you can find zoom in here, which works like a magnifier, allowing you to scale individual areas of the screen on a triple tap.
This mode does not change the size of the font globally, but allows you to zoom in at any time to the desired fragment of text, picture or button. This is especially convenient when working with documents, maps or sites where the layout is not adapted for mobile devices.
Also available in this section is the Enlarged Text feature, which compels the font to be as large as possible in all supported applications, ignoring the limitations of the standard slider, a last resort that can significantly change the layout of the screen, but guarantees readability.
| Function | Impact on the system | Difficulty setting up | Recommended use |
|---|---|---|---|
| The creeper in the Ekran | Only the text changes. | Low. | Daily use |
| Change to DPI | Change the entire interface | Tall. | For experienced users |
| Increase mode | Temporary magnifying glass | Medium | For rare reading of small text |
| Third-party launchers | Change the desktop | Medium | For full customization |
Compatibility issues in applications
Even after carefully tweaking system settings, users may find that some applications still have small text, which is related to how app developers build their products, and many use fixed font sizes in pixels, ignoring the system zoom settings.
This is a problem that is most common in social networks, banking apps and games, and unfortunately, it's almost impossible to influence this from the outside without root rights, but in some cases, changing the font size in the settings of the application itself helps, if the developer has provided such an option.
For example, on Telegram, WhatsApp, or Viber, the font size is set up inside the chat or general menu, which is more important than the system settings, so if you have increased the font in Xiaomi but it is still small in the messenger, look for the setting inside the application itself.
For web browsers, it's the same. In Chrome or MI Browser, you can scale the default page, and you can scale the text on the sites to larger sizes without affecting the rest of the phone interface. Go to your browser settings, look for "Special Features" or "Web Content," and adjust the scale.
⚠️ Note: When using the “Scaling” function in the browser, some elements of the site can “go” outside the screen, requiring horizontal scrolling.
Resetting settings and problem solving
If you experiment with DPI or third-party fonts, your Xiaomi interface becomes unreadable, buttons are missing, or text is crawling on other elements, you need to reset the settings. The easiest way, if the screen is at least partially responsive, is to go back to the developer menu and return the original value of the minimum width.
If the interface is so strong that it is impossible to get into the settings, you will have to perform a full reset of the phone settings (Hard Reset), which will delete all data, so always back up important information before experimenting with system parameters.
To reset through the buttons (if the screen is not working), turn off the phone and press the key combination to enter Recovery Mode (usually Volume Up + Power). From the recovery menu, select Wipe Data or Factory Reset. After this procedure, the phone will return to factory settings, including the standard font size.
- 🔄 Try going into Safe Mode to check if the third-party app is to blame.
- 🗑️ Remove recently installed themes or fonts through the Topics menu» → «Profile» → «Fonts».
- 🛠️ If the screen is not responsive, use button reset via Recovery Mode.
- 💾 Always create a backup before changing system settings DPI.
💡
The most reliable way to avoid interface problems is to change the DPI settings in small steps (no more than 20-30 units) and immediately check the operation of the main applications.
To sum up, Xiaomi offers a lot of options for tweaking font size, from a simple slider in settings to deep customization through DPI, every user can find the right option, and the key is to be careful when working with advanced settings and be aware of the possibility of rollback changes.
