How to Change the Font Size on Xiaomi Phone: A Complete Guide

Modern Xiaomi, Redmi and POCO smartphones have powerful screens, but standard text display settings often don’t take into account the individual characteristics of the user’s vision. Small font can cause eye fatigue, and too large can disrupt the layout of the interface, making navigation uncomfortable. Fortunately, the Android operating system with the shells of MIUI and HyperOS provides flexible tools for personalization.

In this article, we will discuss in detail how to change the font size on a Xiaomi phone to read news, correspondence in messengers and work with documents become as comfortable as possible. You will learn not only about the basic settings, but also about the hidden features that allow you to change the style of displaying text.

We will look at the differences between standard customization methods and the advanced features available in the “Mode for the elderly”, and pay attention to the nuances that users often miss, such as the impact of system fonts on the work of third-party applications.

Basic text size setting in MIUI and HyperOS

The easiest way to zoom in on the content is built into the standard settings menu, which is suitable for most users who just need to make the text bigger or smaller without changing the style. First, open the Settings app and search for the Screen section.

Inside the menu, you'll find a slider that adjusts the size of the font, and as you move it around, you'll see real-time changes on the preview screen, and the system automatically adjusts most interface elements to the scale you choose, but in some older applications, the layout can go.

Note that newer versions of HyperOS may have slightly different logic than the classic MIUI 14. HyperOS often uses more aggressive scaling of controls, making the interface more friendly for people with reduced vision.

⚠️ Note: When setting the maximum font size, some buttons in the settings menu may be cropped or overlapped with text. If you can't find the back or apply button, just zoom in by one division.

Changes are effective instantly, you don't need to restart the device, and if you don't like the result, you can always return the settings to factory values by selecting "Default" from the same menu.

Changes in font style and boldness

Xiaomi allows you not only to resize, but also to adjust the visual perception of text through the fat settings. This is especially true for screens with high pixel density, where thin lines of letters can look blurry. To access these settings, go to Settings → Screen → Text Size and Fat.

Here you'll find a second slider that's responsible for the saturation of the font, which makes the letters sharper and more contrasting, and the bold type that's great for reading in bright sunlight when the screen is shining.

💡

If standard fonts aren't enough, go to the Themes app, select the Fonts section, and download any style you like, and then you can activate it in the main screen settings.

It is worth noting that changing the style of the font can affect the display of special characters or rare languages. If you use several input languages, check the correct display of each of them after the style change.

Some users prefer to use monowidth fonts to work with code or tables. There are no such options in the standard set, but third-party themes often offer such solutions. Installing a third-party font requires read and write rights to the system folder, which is usually available immediately after applying the theme.

“For the elderly” (Lite-mode) on Xiaomi

For users who don't have enough standard font zoom, Xiaomi smartphones have a special mode. It drastically changes the interface, making all elements as large and simple as possible. To activate it, go to Settings → Advanced Settings → Senior Mode.

In this mode, the launcher (desktop) is completely transformed: the icons become huge, the captions under them are read effortlessly, and unnecessary visual effects are turned off. The system font in all menus increases to the maximum possible value.

It is important to understand that switching to this mode changes the logic of the device, some functions may become inaccessible or hidden in the depth of the menu, exiting the mode is done through settings or by long pressing the power button (depending on the firmware version).

⚠️ Attention: In the "For the elderly" mode, the behavior of the control gestures can change. Instead of swipes, you sometimes have to rely on on on-screen navigation buttons, since the touchscreen sensitivity zone is recalculated for large elements.

This mode is ideal not only for the older generation, but also for people with temporary vision problems or for using a smartphone as a simple "caller" in emergency situations.

Screen Scaling (DPI) setting

For advanced users who lack standard sliders, there is the option of changing the dot-per-inch density (DPI) of the device, which affects how much content is placed on the screen, effectively changing the scale of the entire system, including fonts and icons.

To access these settings, you need to activate the Developer Menu. Make 7 quick clicks on the build number in the About Phone section. Then go to Advanced Settings → For Developers and find the Minimum Width (or "Smallest Width").

The standard DPI for most Xiaomi smartphones is 392 or 411, and changing that by 20-30 units downwards will make the font larger, but reduce the amount of visible information on the screen.

Be careful when changing these settings. Too low a DPI can make the interface unreadable, and too high a DPI can make the interface so small that you can't get through the buttons to return the settings. It's recommended to write down the original value before experimenting.

Problems with the display of text in the annexes

Often users are faced with a situation where the system font is changed successfully, but in individual applications (for example, Instagram, Telegram or bank clients), the text size remains the same, this is due to the fact that application developers can ignore the system zoom settings.

In these cases, cleaning the app cache or reinstalling it helps. Sometimes the problem lies in the version of the app itself — try updating it through Google Play or GetApps. If that doesn't work, check the accessibility settings inside the app itself.

There's also a method of forced scaling through the developer menu, so find Force scaling and try activating it, and it will force the system to apply the DPI you choose to even to applications that normally ignore it.

However, it is worth remembering that forced scaling can lead to incorrect display of buttons or overlapping elements on top of each other in the program interface. Use this method only if the standard methods do not work.

Use of special opportunities for the visually impaired

If standard font zoom isn't enough, Xiaomi offers powerful tools in the "Special Features" section, and you can find the Screen zoom function here, which works like a magnifier, activated by triple tapping the screen or through a button in the menu.

There's also a TalkBack feature that voices everything that happens on the screen, and while it doesn't change the visual size of the font, it's a critical tool for people with severe visual impairments to make it possible to use a smartphone.

💡

The combination of the system font enlargement and the Screen Enlargement feature gives maximum comfort to visually impaired users, allowing them to view any interface elements in detail as needed.

To activate these functions, go to Settings → Additional Settings → Special Options. Here you can adjust your speech speed, voice height and magnification gesture sensitivity. Don't be afraid to experiment with settings, as all changes are reversible.

Check system updates regularly as Xiaomi is constantly improving text rendering algorithms and adding new accessibility options to each new version of MIUI and HyperOS.
