Modern smartphones like the Xiaomi Redmi 8 come with high-pixel density screens that provide a clear picture, but often make standard text too small for comfortable reading. Visually impaired users or those who simply prefer large typography face the need to adapt the interface to their needs. Owners of devices based on MIUI may find that standard sliders do not give the desired result, and the text remains not large enough.
Fortunately, the Android operating system that underpins the MIUI shell provides advanced tools to fine-tune content. Resizing the font is not just a matter of aesthetics, but an important accessibility feature that reduces eye strain and makes it more enjoyable to use. In this article, we’ll take a look at all the available methods, from simple menu settings to harnessing the system’s engineering capabilities.
You'll learn not only to zoom in on messages and menus, but also to scale the entire interface, which is especially true for models with a diagonal of 6.22 inches, like the Redmi 8. We'll also touch on performance issues, as improper zooming can affect the layout of some applications.
Basic text size setting through menu
The easiest and safest way to resize your characters is to use the standard tools of the system. Smartphone manufacturers understand the importance of accessibility, so MIUI provides a convenient slider that allows you to instantly assess the changes. First, you need to get to the main settings menu of your Redmi 8. Find an icon with the image of a gear on your desktop or in the notification curtain and click on it.
In the settings that you'll see, you'll need to find the look section that's going to be used in different versions of the firmware, but most often, the item you're looking for is hidden inside the Settings tab, and that's where you find the settings that affect how you see the interface, including themes, navigation buttons, and of course fonts.
When you go to the right section, you'll see text size, and if you click on it, you'll open a new window with a horizontal scale, and if you move the slider to the right, you'll see the size of the letters in the text example at the top of the screen change, and that gives you the optimal value that makes the text readable easily, but the controls don't go beyond the display.
Importantly, this change affects system fonts, settings menus, messages, and most of Xiaomi’s standard apps, but some third-party programs, such as instant messengers or social networks, may ignore system settings and use their own display options, which will have to be changed separately within each application.
💡
If you accidentally knocked down the settings and the text became unreadable, just shake the phone (if the feature is enabled) or use the voice assistant to return to the settings menu.
Scaling interface elements and DPI
Sometimes even the maximum font size is not enough, or the user wants to increase not only the text, but all the interface elements: icons, input fields, indentations. For such cases, there is a parameter in Android known as DPI (dots per inch) or "Less width." Changing this parameter forces the system to recalculate the density of pixels, effectively increasing all objects on the screen.
To access these settings, you need to activate the developer mode. On Redmi 8, this is done by repeatedly clicking on the build number in the About Phone section. After seven quick taps, the system will notify you that you have become a developer. Be careful: this mode is designed to test applications, and inadvertently changing some parameters can disrupt the system.
In the developer menu, find the "Less Width" item. Remember or write down the original value (usually 360 or 392 dpi for this model) so you can go back. Reducing that number leads to zooming. For example, if you set the 300 value, all the elements will be noticeably larger, but less information will fit on the screen.
⚠️ Note: Do not set too low values DPI (This can cause some control buttons to become unavailable, as they will “go” outside the visible area of the screen, and it will be extremely difficult to return the settings back without resetting the data.
Using DPI zoom is a powerful tool that allows you to tailor the interface to the specific needs of visually impaired users, but it is worth remembering that when you zoom in, some applications may not display correctly, since their layout is not designed for such large elements.
Use of magnification mode (Loop)
For users who sometimes need to look at small details but are uncomfortable keeping a huge font, MIUI and Android have built-in zoom in, which works like a virtual magnifier, allowing you to zoom in on any part of the screen by double-tapping or through a special button.
You can activate this feature in Advanced Settings → Special Features → Enlargement. Here you can choose the activation method: triple touch the screen or floating button. The second option is often more convenient, since it does not require accuracy of hitting with a finger, which is important for people with hand tremors or low vision.
When the mode is activated, the screen responds to zoom gestures similar to those used in a gallery or browser, so you can pinch your fingers to enlarge the text area and move the enlarged window across the screen, which is the perfect trade-off between readability and functionality.
Set up the font in popular applications
Despite the system settings, many users spend time on specific applications, such as WhatsApp, Telegram or Viber, which often have their own text display settings, which are prioritized over the system, and to achieve maximum comfort, you need to configure each of them separately.
In Telegram, for example, the way to set up is through Settings → Chats → Font size. You have your own slider that allows you to make messages in dialogs much larger than the rest of the system. Similar situation with WhatsApp: go to Settings → Chats and turn on the option Font size by choosing "Large" or "Huge".
Browsers also require special attention. In Google Chrome or MI Browser, you can scale the default page. This is especially useful for reading news and articles, where the font is often small. In your browser settings, find the Special Features or Web Content section and zoom in to 120-150%.
☑️ Checking application settings
Remember that when you update your apps, your settings may reset to standard values, so if you notice that the text is small again, check the internal settings of your application, not just your system.
Comparison of sizing modification methods
To make it easier for you to choose the best method, we have prepared a comparison table that will help you weigh the pros and cons of each method, taking into account your individual needs and the level of ownership of the Xiaomi Redmi 8 smartphone.
| Method | Difficulty | Impact on the system | Recommendation |
|---|---|---|---|
| System slider | Low. | Only text | For all users |
| Change to DPI | Tall. | The interface. | For experienced users |
| Loop mode | Medium | Temporary increase | For periodic use |
| Application settings | Low. | Only a specific annex | For messengers. |
As you can see from the table, the standard method is the safest and most versatile, it ensures that the system is stable and that all elements are displayed correctly, and more advanced methods, such as changing the DPI, are only justified if the standard tools are not enough.
💡
Always start with minimal changes. Scale up gradually, checking usability after each step.
Possible problems and solutions
Redmi 8 users may encounter some difficulties in customizing, such as when the font is enlarged, text in some menus may be cropped, ellipsing important words, due to the fixed width of some interface elements in the MIUI shell.
Another common problem is the “gotten” layout in third-party applications, buttons can overlap and input fields become too narrow, in which case it is recommended to either zoom in slightly or use the horizontal orientation of the screen to read long texts.
If you change the DPI settings and the interface becomes unreadable and the buttons don't click, don't panic. Try running the Themes or Gallery app -- sometimes they ignore the system scale and allow you to go into the settings. If that doesn't help, you'll have to reset your phone to factory settings, saving important data beforehand.
⚠️ Attention: Before drastic changes to the developer menu, make sure to back up the data. Restoring access to the settings menu without resetting in case of critical zooming errors is impossible.
