How to Make a Font More on Xiaomi: From Standard Settings to Hidden Features

Small font on Xiaomi’s screen is a common problem for users, especially after buying a new smartphone or updating MIUI. Even on large Redmi Note 12 or POCO X5 Pro displays, text can seem inaudible, and in some applications (such as Google Chrome or Telegram), letter sizes do not defy standard settings at all. In this article, we will discuss all possible ways to increase the font – from basic system parameters to hidden functions for users with visual impairments.

It is important to understand that changing the font size works differently depending on the version. MIUI (12, 13, 14 or HyperOS) and device models, such as the Xiaomi 13 Ultra with AMOLED-screen scaling can be automatically adjusted for resolution, and on the budget Redmi A2 We've taken these nuances into account and developed universal solutions that will work on 90% of the brand's devices.

1. Standard font settings in MIUI

The most obvious way is to take advantage of the built-in settings, which is suitable for all Xiaomi, Redmi and POCO smartphones, regardless of the firmware version.

1. Open the Settings app (the gear icon on the home screen).
2. Go to the Screen section (on some models – Display).
3. Select Text Size or Font and Display Size.
4. With the help of the font size slider, adjust the value from Small to Very Large.

If you are happy with the new size, click Ready or Apply. Note that some apps (such as Instagram or TikTok) may ignore the system settings of the font – they will require additional actions (we will discuss this below).

An important nuance: on HyperOS devices (such as Xiaomi 14 or Redmi K70), the path to font settings may be different. Instead of screen, look for the Decoration → Font and Size section. Newer versions of firmware also include the Fat option, which makes text more contrasting without changing the size.

2. Screen scaling (Display Size)

If zooming in on the font doesn't solve the problem, try zooming in on the whole interface, which not only increases text, but also the icons, menu items, and even some graphical elements in the apps, which is suitable for users who have trouble seeing the small details on the screen.

Instructions:

• 📱 Open the Settings. → Screen. → Display size (or screen size).
• 🔍 Select one of the preset options: By default, Large or Very Large.
• 🔄 If the desired size is not, tap on Additional and manually move the slider.

On models with Full HD+ (1080×2400) resolution and higher, zooming can cause text to blur in some applications. This is because the forced upscaling system is used to increase elements. If image quality deteriorates, return the settings to the default value and use only the font zoom.

Check the current screen resolution (Settings → About Phone → Features)

3. Mode for the visually impaired (TalkBack and High Contrast)

If standard settings don't work, MIUI has specialized features for users with vision problems that not only increase font, but also improve contrast, add voice and make navigation easier.

How to turn on:

1. Go to Settings. → Special facilities.
2. Select the zoom or screen speaker (TalkBack).
3. Activate the option Magnifying glass – now you can tap three times on the screen to enlarge any of its parts.
4. For maximum contrast, include High contrast (makes the text black on a white background or vice versa).

🔹 TalkBack is a voice assistant that voices all actions on the screen, useful for people with severe visual impairments, but requires training: the control gestures change (for example, one tap highlights an element, and a double tap activates it).

⚠️ Note: TalkBack mode may conflict with some banking applications (e.g. SberBank Online or Tinkoff.

4. Change of font in individual applications

Some programs (e.g., Chrome, WhatsApp, or VK) ignore the system font settings, and you have to adjust the text size separately.

🔹 There are no official font settings for Instagram and TikTok, but you can use system zoom (see section 2) or third-party apps like Big Font (available on Google Play).

Developer tip: If you’re building your own app and want it to respect the system font settings, use the android:textAppearance option with the?android:attr/textAppearance attribute in the code, which ensures that all Xiaomi devices zoom in correctly.

5. Installation of custom font through themes

MIUI has a hidden option to install custom fonts with enlarged characters, which requires additional actions, but gives you more freedom to customize.

Step-by-step:

• 🎨 Download a font with large characters (such as Roboto Bold or Open Sans ExtraBold) in.ttf format.
• 📁 Put the file in the folder. MIUI/theme/fonts (Create it if it doesn’t exist).
• 🔧 Open the Settings. → Registration → Fonts.
• 🖱️ Select the downloaded font and apply it.

🔹 Xiaomi with HyperOS, the path to fonts may be different: Internal Storage → MIUI → Theme → CustomFont. Also, some firmware blocks the installation of third-party fonts - in this case, root rights will be required.

⚠️ Attention: Poor fonts can cause system applications to crash (such as Settings or Phone.

6. Resetting display settings to factory

If, after experimenting with fonts and scale, the interface starts to look incorrect (blurred icons, cropped text, display errors), you can return everything to its original state by resetting the screen settings. This does not affect personal data, but returns all display parameters to factory ones.

Instructions:

1. Open Settings → System and device → More
2. Select Resettings → Resetting of display settings.
3. Confirm the action with a password or pattern lock.
4. Wait for the device to restart (it will take 1-2 minutes).

🔹 In some models (for example, POCO F5) The option to reset the display may be located elsewhere: → The phone. → Resetting settings → Resetting screen settings.

💡

If the font is small again after reset, try updating the firmware. Newer versions of MIUI often fix zoom bugs. Check for updates in Settings → About Phone → System Update.

7 Problems and Solutions: Why the Font Has Not Changed

Sometimes users find that the font does not increase at all efforts.

• 🔄 Cash Systems: Clear the cache in Settings → Annexes → Application management → ⋮ → Clear the cache.

• 🔧 Conflict of topics: If you use a custom theme from the Mi Theme Store, it can block the change of font.
• 🛠️ Firmware damage: If after updating MIUI The font is lost, try reinstall the firmware through Fastboot.
