How to increase the font size on Xiaomi phone

Xiaomi’s modern smartphones have great high-pixel-density screens, but standard font settings aren’t always comfortable for users, especially for people with low vision or those who use the gadget frequently in bright sunlight. MIUI and the new HyperOS provide flexible tools for personalization, but they’re not always obvious at first glance.

In this article, we will not only discuss basic methods of resizing text, but also advanced techniques that will help make the interface as readable as possible. You will learn how to scale individual elements of the system, use a magnifier mode, and even change system fonts without obtaining root rights.

Before we get to the tricky side of this, we need to consider the standard interface adaptation tools, which are built into the skin of the manufacturer and do not require the installation of third-party software, and this is the safest and most stable way to solve the problem of small text on your Xiaomi, Redmi or POCO device.

Basic setting of font size in the menu

The easiest and most obvious way to change text display settings is in the standard settings menu, which affects all system applications, including messages, contacts, and the standard browser, and first you need to go to the Settings section, which is usually represented by the gear icon.

Then the algorithm of actions may vary slightly depending on the version of the shell. In current versions of MIUI 14 and HyperOS, the path is as follows: select the screen, then go to the subsection "Size of text and font", here the slider adjusts the scale of characters in real time.

If you have an older firmware version, look for the "Advanced" or "Advanced Settings" section. In some regional builds, the menu may be called "Special Features," although this is less common for basic font settings. It's important not to confuse text size change with image size change (scaling) that's in the next menu.

• 🔍 Open the Settings app on the main screen.
• 📱 Go to the screen or display section».
• ✍️ Select the item "Size of text and font».
• 📏 Move the slider to the right to increase the symbols.

Note that as you maximize the font, some interface elements can drive or crop in narrow dialog windows. This is normal system behavior at extreme values. After setting up, be sure to scroll through multiple menu screens to make sure the text is read comfortably and does not overlap the control buttons.

⚠️ Note: When setting the maximum font size, some third-party apps may not display text correctly, as they use their own rendering engines that ignore the system scaling settings.

Changes take effect instantly and don't require rebooting the device. If you don't like the result, you can always return the slider to its original position. The system remembers the last profile you selected, but it doesn't store the history of previous values, so it's better to remember the original position before global changes.

Change the size of interface elements (Scaling)

Often, users don't just need to zoom in on the letters, they need to make all the controls bigger: icons, buttons, input fields, and indentations, and this is called Element Size (or Scale), which works regardless of the font size, allowing you to combine settings for the perfect result.

This option is usually on the same menu as the font settings. In MIUI, it's often a separate slider called "Element Size," and by zooming in, you make the interface sparse and larger, which is especially convenient on large-screen smartphones, where the top elements are sometimes hard to reach with your finger.

There's an important caveat: Excessive zoom can cause critically little information to be placed on the screen, for example, you'll see only three in the contact list instead of ten names, so balance is considered the best solution when the font is enlarged by 1-2 divisions, and the scale of the elements is left average or also slightly enlarged.

Some users mistakenly believe that scaling only affects the desktop; it is not: the changes affect the system menus, notification curtains and standard applications of Xiaomi. However, in “heavy” applications like Instagram or Telegram, the effect may be less noticeable due to the adaptive layout of these programs.

Use of magnifier regime for visually impaired

If standard magnification isn’t enough, Android offers a powerful accessibility tool called “Lupu,” which turns your smartphone into a magnifying glass, allowing you to zoom in on any part of the screen by double-touching or floating a button.

You can activate the magnifier through the Special Opportunities menu. Depending on the version of MIUI, this section may be called Advanced Settings → Special Features. Search the Loop or Magnification list and switch the switch to the active position. Now the magnifier icon will appear on the screen or gesture control will be activated.

The magnifier mode has its own peculiarities: When the function is turned on, triple tapping the screen (or double tapping, depending on the setting) causes a larger window that can be moved with your finger, which is ideal for reading small text in web browsers or viewing details in images without having to change the system fonts globally.

• 🔎 Go to "Settings» → «Additional settings».
• ♿ Select "Special Opportunities».
• 👁️ Find and include the item "Lupa».
• 👆 Use triple tapping to increase the screen area.

It's important to understand the difference between a magnifier and a zoom in a gallery. A magnifier enlarges the entire interface, including navigation buttons and a status bar, whereas zoom only works inside a specific content application. For older people, it's often more convenient to configure the display of a floating magnifier button so as not to remember complex combinations of touches.

Download and install new fonts

MIUI is famous for its customization, and one of the most popular features is "Themes," which allows you to change not only wallpaper and icons, but also system fonts, some of which initially have a larger shape or better readability.

To use this feature, open the Themes app (an icon with a brush or Themes label). At the bottom of the screen, look for the Fonts tab. Here is a catalog of free and paid fonts. Sort them by popularity or search for "Large" or "Bold" to find options with a larger size.

Once you download and use the font, the phone will ask for a reboot, which is a must-have, because replacing the system font file requires a restart of the interface services, and once you turn on, you'll notice that the text is not only larger, but also visually altered, which also helps you get a better sense of information.

Keep in mind that third-party fonts may not support all languages or special characters. If you see squares instead of letters in some applications, then the selected font does not have glyphs for these characters, in which case it is better to go back to the standard font Mi Sans or Roboto, just increasing its size with a slider.

Adjusting the fat and contrast of the text

Size is not the only variable that affects readability; font fat is critical, especially on low-brightness screens or when using protective glasses that can give glare. Modern versions of HyperOS and MIUI 14 have the ability to separately adjust the boldness of text.

This setting often hides in the same menu as the font size. Look for a Fat Switch or a weight slider. The increase in fat makes the characters more massive and noticeable, which visually equates to a slight increase in size. This is especially true for thin sans-serif fonts.

Also, you should pay attention to the design theme: Dark Mode combined with large font significantly reduces the load on the eyes at night. In the screen settings, you can turn on Read Mode, which adds a warm filter and can slightly increase the contrast of the text, making it clearer.

On Xiaomi smartphones with 120Hz screens, text looks sharper and doesn’t smear when scrolling, making it easier to read long articles. Make sure the screen settings (Refreshment Frequency) choose the default or 120Hz value, rather than the 60Hz value, to save energy if reading comfort is a priority.

Solving problems with display in applications

Sometimes system settings are applied, the text in the menu is large, but in specific applications, such as Viber or Chrome, the font remains small, which is due to the fact that application developers can ignore the system zoom settings or use fixed font sizes in their layout.

In such cases, you need to look for settings inside the application itself. Most messengers (WhatsApp, Telegram) have a section called Chats and Calls or Data and Memory, where you can separately increase the size of the message font. In Chrome, the settings are in the Settings menu → Special Features → Scaling text.

If an application doesn't have its own font settings, you can try forced scaling through an engineering menu or ADB, but that requires caution. A safer method is to use the zoom feature in special features, which runs on top of any application, forcibly scaling the contents of the screen.

⚠️ Note: Using third-party programs to globally modify fonts (such as FontFix or HiFont) on new versions of Android can lead to unstable system operation or the appearance of banner ads in the interface.

It's also worth checking if the One Hand or Screen Slimming mode is on, which compresses the image for easy control of a large phone, which can visually reduce all elements, negating your efforts to zoom in on the font.
