How to increase the font size on Xiaomi Redmi 9: Step-by-step instructions

Owners of the Xiaomi Redmi 9 smartphone often face the need to adapt the interface to their visual preferences or vision. Standard screen settings set by the manufacturer may seem too small for older people or, conversely, take up too much space for those who are accustomed to high density of information. The MIUI shell provides flexible tools to customize the displayed text, allowing you to make use of the gadget as comfortable as possible.

The process of changing the font settings does not require root rights or deep knowledge of programming. All the necessary functions are built into the standard menu of system settings. However, it is worth considering that increasing the size of the text can affect the layout of some applications and the number of characters displayed on the screen at the same time. In this article, we will discuss in detail all available methods of zooming and customizing fonts.

Also, resizing the font is not just a matter of aesthetics, but also an important accessibility feature. A properly configured interface reduces eye strain when reading news, texting in messengers or viewing documents. We will look at both the basic settings and the hidden features of the system that will help you personalize Redmi 9.

Standard font size settings in MIUI

The easiest and safest way to change text size is to use the built-in tools of the Android operating system with the MIUI add-on. This method does not affect the stability of the device and applies to all system applications that support standard font APIs.

In the list that opens, find a section that is usually labeled "Screen" or "Display." Depending on the firmware version, the path may be slightly different, but the logic remains the same. Inside this menu, you find a paragraph that is responsible for the size of the text. When you click on it, you will see an adjustment slider, which moves instantly changes the size of the characters on the screen.

⚠️ Attention: With a large font increase, some interface elements can "go" or stop fitting on the screen without scrolling. This is normal behavior for applications that are not optimized for large fonts.

Once you select the optimal value, the system will automatically apply the changes. You don't have to restart the device to see the result. However, it's worth checking the text display in different applications, since some third-party programs may ignore the system settings and use their own zoom parameters.

Step-by-step: changing the display parameters

For those who prefer to act consistently, we have prepared a detailed algorithm of actions. Follow these steps to ensure that you achieve the desired result on your Xiaomi Redmi 9. Accuracy of execution of instructions is important so as not to get confused in the settings menu.

First, unlock your smartphone screen and find the Settings icon (cogs). When you enter the menu, scroll down to the "Advanced" section or immediately look for "Screen." Newer versions of MIUI often have font settings in the "Text and display" subsection.

When you move the slider, notice the preview, which is usually displayed at the top of the screen, and it shows you what the text will look like in different sizes. Once you set it up, press the "Done" button or just go back, the settings are saved automatically, and if you don't have the standard range, you can move on to more advanced methods.

Use of interface scaling mode

Sometimes just zooming in on the font isn't enough, because buttons and icons are small, and in these cases, the "Imagine Size" or "UI Size" feature comes to the rescue, which not only increases text, but also all controls, making the smartphone more convenient for people with visual impairment.

You can find this setting in the same menu where you changed the text size, or by searching the settings by typing in the query "scale." It's important to understand the difference: the font size changes only the letters, and the interface scale increases everything proportionally. This can be especially useful when using a touch screen, making the buttons larger and easier to press.

When you enable maximum zoom, the number of visible lines on the screen will decrease significantly. This is a trade-off that has to be made for readability. For Redmi 9, with its screen diagonal, this could mean that in landscape orientation, some apps will look like a tablet with very large elements.

💡

If the keyboard becomes too large or small after the font scale change, go to the settings of the keyboard itself (usually Gboard or Mi Keyboard) and change its height separately.

Installation of additional fonts through the theme of design

MIUI is famous for its flexibility in personalization, and one of the main tools here is the Themes app, which allows you to not only change icons and wallpapers, but also install completely new fonts that can be initially larger or simply readable than standard ones.

To do this, open the Topics app on your desktop. In the bottom navigation bar, select the Fonts tab (or Profile -> Fonts) and there's a catalog of free and paid fonts. Some of them, like Sans Serif or specialty fonts for reading, have a bolder outline and increased letter proportions.

After selecting the font you like, click Download and then Apply. The device may ask for a reboot to properly display all elements of the system. Remember that third-party fonts may not be supported by some applications that force their own character set.

Reading regime and vision protection

Boosting the font isn’t the only way to make reading on the Xiaomi Redmi 9 more comfortable.The smartphone has a special “Read Mode” built in, which changes the color temperature of the screen, making the background more yellow and similar to electronic paper.

You can activate this function through the Quick Access Panel (top-down swipe) or in screen settings. Reading mode can run on a schedule or turn on automatically when you run certain applications, such as Books or Browser. The combination of large font and read mode gives the best result for long-term text work.

Also worth mentioning is the Accessibility Zoom feature, which allows you to temporarily enlarge part of the screen with a triple tap. It doesn't change the system font, but allows you to see the details in the map or in the photo, and you can find this option in the Advanced Settings section -> Special features.

Solution: The font does not change or is too large

Users sometimes find that after applying the settings, the font in some applications remains the same, often because app developers (such as Telegram or Viber) set their own text display parameters, ignoring the Android system settings.

In these cases, you have to look for the font settings inside the application itself, and they're usually in the Settings section --> Chats and Backgrounds or General -- where you can, regardless of the system, increase the size of the text you're texting, and that's flexible: you can have a small font on the system for compactness, but you can have a large one on the messenger.

⚠️ Warning: If after installing a third-party font from the Tomes, the interface becomes unreadable (letters are missing or squares appear), immediately restart the phone to Safe Mode or quickly select the standard font in the Topic app until the system is disabled.

If the font is so big that you can't press the back button or log in to fix the situation, use settings search. On the main settings screen at the top, you have a search bar, write "font" or "size" there, and the system will open the menu itself, even if the buttons are hidden outside the screen.

💡

For full control over the display of text, combine system size settings, interface scale, and built-in font settings in specific applications.
