Modern smartphones like Xiaomi Mi 9T, furnished AMOLED-It's a very high-pixel density screen, which is a crystal clear image, but the standard interface settings are the same. MIUI Not always perfect for every user, especially those who wear glasses or have vision problems. Small text in the system menu or messengers can cause rapid eye fatigue and discomfort with prolonged use of the gadget.
Fortunately, Android’s MIUI-enabled operating system provides flexible tools to personalize content display. You can change not only character size but also boldness, which has a significant impact on readability. In this article, we’ll take a closer look at all the ways fonts are customized, including hidden features that not all device owners know about.
The methods discussed below are relevant to the Mi 9T model, but can also be applied to other smartphones of the brand with minimal differences in the interface. The correct configuration of the display will make interaction with the device more comfortable and safe for your vision.
Standard text size setting in MIUI
The most obvious and safe way to change the scaling of interface elements is in the basic system settings. This method does not require root rights or install third-party software. You need to open the main menu and find the gear icon that indicates the settings section. Next, follow the Settings → Screen → Text Size path.
In the window that opens, you'll see a slider that changes the font size in real time across all supported apps, and offers multiple-tone options, from "Little" to "Huge." It's important to note that changing this setting affects the system font, settings menu, contacts and standard apps from Google and Xiaomi.
⚠️ Note: When setting the maximum value, some interface elements can “go” or overlap with each other in older versions of applications that are not optimized for large fonts.
If you don't have the standard range, you can try to change not only the size, but also the style. In this section, the "Large Font" option is often available, which simplifies the launcher interface by making the icons and captions as large and readable as possible, and it's a great solution for handing the smartphone to less experienced users.
Adjusting font boldness for better readability
In addition to the physical size of letters, the perception of information is strongly influenced by their saturation. MI Sans on the bright AMOLED-screen 9T They can blend in or look pale. MIUI There's a separate function for changing the fat content, and you can find it on the Settings path. → Screen. → Text (or “Bold").
Activating this option makes the characters denser and more contrasting, which is especially useful when using the phone in bright sun. However, it is worth considering that increasing the thickness of the lines can visually reduce the space on the screen, as letters begin to take up more space horizontally, this can lead to the transfer of lines in long sentences.
The use of bold marking is recommended for users who often read e-books or news directly from the smartphone screen, which reduces the load on the eye accommodating apparatus. Once the function is turned on, the system may require a reboot of the interface or the device itself to apply changes to all services.
💡
The combination of medium font size and the included fat option often gives a better reading result than just maximizing the size.
Global Screen Scaling (DPI)
For advanced users who lack standard settings, there is the option of changing the dot-per-inch density (DPI) parameter. This parameter determines how many pixels are allocated to display a single interface element. Changing the DPI allows you to increase the font on the Xiaomi Mi 9T globally, affecting even those elements that ignore the system text size settings.
To access these settings, you need to activate the developer menu. → On the phone and press quickly 7-10 once-in-the-line MIUI". After the message "You became a developer" return to the main settings menu, select Advanced Settings → For developers, find the "Smallest width" item).
Remember or write down the original value (usually for the Mi 9T it is about 360-390 dp) to be able to return everything back. Reducing this number (for example, to 320) will make all elements, including fonts, larger. Increasing the number will, on the contrary, reduce the interface. Be careful: setting a value too low can make the interface unusable, and then you have to reset the settings through Recovery.
| Parameter DPI | Impact on the interface | Recommendation |
|---|---|---|
| Less than 300. | Very large elements, little content on the screen | For the visually impaired |
| 360-390 | Standard display | Factory setting |
| 400-420 | The elements get smaller, more space. | For experienced users |
| More than 450. | The text becomes very small, difficult to read. | Not recommended |
Risks of changing DPI
Use of the increased text mode in the browser
Often users do not need to increase the font in the entire system, but specifically when reading articles on the Internet. Browsers based on the Chromium engine (Google Chrome, Yandex.Browser, Mi Browser) have their own zooming settings that overlap the system, which allows you to keep the compact interface of the phone, but it is comfortable to read text on sites.
In Google Chrome, you have to click three dots in the corner of the screen, select Settings → Special Features. There you will find the page size slider. Moving it to the right will increase the content of all tabs. Also useful is the feature "Forced Scaling Enabler", which allows you to zoom in sites that were not originally adapted for mobile devices.
In Xiaomi’s browser (Mi Browser), the logic is similar: go to the user profile (human icon), then to the settings (cogs) and find the “Site settings” or “Scale” section. Here you can set a fixed zoom level by default, which is especially true for Mi 9T owners with its wide screen, where on standard versions of sites the text may seem too small.
- 🌐 Use the night mode in the browser to reduce contrast and eye load.
- 🔍 The function "Text version" in some browsers removes all graphics, leaving only large readable text.
- 📱 Double touching on the screen in the browser often automatically scales the column of text under the width of the display.
☑️ Checking the display settings
Special opportunities for the visually impaired
There's a powerful section in Android that's designed specifically for people with disabilities, but it's useful for everyone, and the Accessibility section allows you to ignore the limitations that app developers have on font size, and you can find Magnification here.
Activating the zoom function allows you to use the screen as a magnifier, so you can quickly tap the screen three times (triple tap) to enlarge a specific area, or you can turn on a permanent magnifier in the corner of the screen. This doesn't change the font size globally, but it allows you to look at the fine text in detail at any time without changing the system settings.
Also available in this section is the Large Text feature, which forcefully increases the font size in many applications, even if they try to dictate their sizes, a more aggressive measure than standard settings on the screen menu, and it often helps in situations where conventional methods are powerless.
⚠️ Warning: Enabling special features may consume additional battery power, as the system constantly monitors the touches of the screen to activate the magnifier.
Installation of third-party fonts through Topics
MIUI is famous for its store of themes that allow you to change not only wallpaper, but also system fonts. Some of the available fonts initially have a larger mark or a higher character height, which visually solves the problem of small text, it is a safe way of customization, without requiring superuser rights.
Open the Themes app on your Mi 9T. In the bottom panel, select the Fonts tab. You can search for "Large," "Big," or just Browse. When you choose a font, pay attention to the preview — often it immediately shows how large the characters are. After download, click "Apply."
It is worth noting that some third-party fonts may not display the Cyrillic alphabet (Russian letters), replacing them with squares or a standard font. Before installing, be sure to check the support for Russian in the description or on screenshots. After using the font, it is recommended to restart the device for correct display in all applications.
💡
Before you install a new font, take a screenshot of your current screen settings or take a picture of them. If the new font is uncomfortable, you can quickly return the original values.
Problems with display in specific applications
Sometimes users are faced with a situation where the font is enlarged in the system, but in specific applications (for example, Instagram, older versions of bank customers or games), the text remains small.
In such cases, only the internal configuration of the application can help: Go to the settings of the problem program (usually the gear icon or three dots within the application) and look for the "Design", "Chat" or "General" section. There is often a slider "Message size" or "Font size".
If you don't have an internal setup, you can try changing the screen resolution or DPI, as described above, but it will affect the whole system. There are also launcher applications that can force their display rules, but they require deep integration into the system and can run unstable on MIUI.
