Xiaomi, Redmi and POCO smartphone owners often face the need to change standard text display settings, whether due to age-related vision impairment, a desire to make the interface more readable, or simply individual user preferences. The standard MIUI and HyperOS font settings provide ample opportunities for personalization, but not all of them are obvious on first acquaintance.
The right character size and style setting can greatly improve the comfort of everyday use. In this article, we will take a look at all the available typography changes, from basic system settings to hidden features for advanced users, learn how to avoid application layout problems and make text really large and legible.
Basic setting of font size through the menu
The easiest and safest way to resize text is to use the built-in tools of the Android operating system with the MIUI shell installed. To do this, you need to open the main settings menu and find the section responsible for the appearance of the interface. The path to the desired parameters is usually standardized, but the names of items may vary slightly depending on the firmware version.
Go to the Settings menu and select Screen. You're interested in Text Size. When you click on it, you'll see a slider that moves left or right will instantly change the font size in the system menus and supported applications. There are several preset levels available, from "Small" to "Very large."
⚠️ Note: When choosing the maximum font size in some third-party applications, text can overlap or go beyond the screen, since software developers do not always provide extreme scaling values.
If the standard magnification range is not enough, the menu often includes a link to additional settings. Activation of the function Large text (or "enlarged text") adds a few more steps of zoom, making the characters really huge, this solution is ideal for people with reduced vision, who are critically important high contrast and letter size.
Advanced Scaling and DPI settings
For users who lack even the maximum system constraints, there is the possibility of changing the pixel density (DPI), which affects not only the size of the fonts, but also the scale of all interface elements, including icons and indentations. Changing the DPI is a powerful tool that requires caution, since it affects the global layout of the system.
To access these settings, you need to activate the developer mode. Go to Settings. → On the phone and press quickly 7-10 once-point version MIUI (or OS), until you get a message about the successful activation, and then a new section will appear in the settings menu. → For developers.
Inside the developer menu, scroll down to the "Drawing" section. Find the "Smallest width" option. Remember or write down the original value (usually around 360-392 dp) to be able to go back, and reducing that number will lead to an increase in all the elements on the screen, including fonts.
⚠️ Warning: Do not set the minimum width too low (less than 200 dp) This can make the interface unreadable or cause a graphics shell to crash and then have to reset the settings via Recovery.

Instructions for changing type of font (MIUI fonts)
MIUI is famous for its flexibility in customization, and changing the typeface is one of the popular features. You can replace the standard system font with a bolder, rounder, or simply more readable counterpart.
Open the Themes app and go to profile (human icon) or find the Fonts button in the bottom menu. Here is a catalog of free and paid fonts. Many of them are optimized specifically for Xiaomi smartphone screens and provide better readability compared to the standard font.
After selecting your favorite option, click Download and then Apply. The system may suggest restarting the device to correctly display changes in all applications. It is worth noting that some third-party fonts may not support Cyrillic or specific characters, so check for Russian letters in preview before installing.
☑️ Checking font legibility
Use of reading mode and dark theme
Increasing font size isn’t the only way to improve your perception of information: a combination of large characters with the right color mode can reduce eye strain. Xiaomi smartphones have a built-in Read Mode that adds a warm yellowish filter that mimics paper.
You can activate it through the notification curtain or in the Settings menu → Screen → Reading Mode. Here you can adjust the heat level and even select the "Paper 1" or "Paper 2" mode, which changes the color gamut of the interface to black and white or sepia, which in combination with a large font gives an excellent result for long-term text work.
Also worth mentioning is Dark Theme: White text on a black background is often more easily perceived, especially in low light conditions, and you can turn it on in the notification curtain or through Settings. → Screen: In the dark theme settings, there is a "Dark Level" slider that allows the background to be dark gray rather than pure black, which reduces contrast and reduces the "lubrication" effect on the background. OLED-screen.
💡
For maximum eye comfort, use a bundle: Large print + Dark subject matter + Autobrightness. It'll reduce energy consumption by AMOLED-screens and reduce fatigue.
Functions of special opportunities for visually impaired
If standard font zoom isn't enough, Android offers powerful tools in the Special Features section, which are for people with severe visual impairments, but can be useful in other situations. The main tool here is the Magnifying.
The magnifier allows you to scale a certain part of the screen with gestures without changing the global font settings. You can activate it from the Settings menu → Additional settings → Special. features → Magnifying. Once turned on, a button will appear on the screen or a gesture will be assigned (for example, triple tapping the screen) to activate the magnifier.
Another useful feature is TalkBack, which, while it completely changes the logic of the control (by voicing all actions), in emergency cases, you can use the "Select for voice" feature, which reads the highlighted text out loud, which helps you perceive information when visual contact with small text is not enough.
| Function | Where to find out. | Influence of type | Recommendation |
|---|---|---|---|
| Size of text | Settings → Screen | Global increase | Basic setup for everyone |
| Large text | Settings → Screen → Text Size | Adds extreme dimensions | For people with poor eyesight |
| Minimum width (DPI) | For developers | Scaling up the entire interface | Only for experienced users |
| Magnifying. | Special opportunities | Local magnifying glass | To read small text in photos/maps |
Frequent problems and their solution
When you change the system settings of the fonts, users sometimes encounter artifacts, such as in some applications of banks or social networks, text may be cropped, buttons become non-clickable, and the menu moves away from the screen, this is because the layout of the application is rigidly fixed and does not know how to adapt to the changed system fonts.
In such cases, it is recommended to create an exception for a specific application. The newer versions of MIUI and HyperOS have a function called "Special Application Properties". Go to Settings → Apps → All Apps, select the problematic application and find the item related to font size or scale (if available), and reset it to the default value.
If the problem affects the entire system after changing the DPI, the only way out is often to reset settings via Safe Mode or completely delete the settings data. To avoid this, always change the settings gradually, Step-by-step, and check the display in the main working applications.
💡
The optimal balance between readability and functionality is achieved by using a text size system slider without changing the DPI, unless the user has specific vision requirements.
