The screen size on Xiaomi smartphones is one of the things that affects the comfort of your device every day: too small text in your browser, uncomfortable desktop icons or blurry interface elements can seriously spoil the experience of the gadget. Fortunately, the manufacturer has provided several ways to adjust the display, from global changes in font size to fine-tuning the scale for individual applications.
In this article, we will look at all the current scaling techniques on Xiaomi, Redmi and POCO phones, from standard tools in the settings menu to hidden features for power users. We will focus on the typical problems: why the text became blurry after the MIUI update, how to return to standard scale if the screen looks “broken”, and what to do if the zoom settings are blocked. All instructions are tested on the latest versions of MIUI firmware 14/15 and are relevant to models from 2020-2026.
1. Global screen scale change through settings
The easiest way to adjust the size of interface elements is to use the built-in display zoom settings, which affects all system applications, icons and text, but does not affect third-party programs (they will require separate settings, which will be discussed below).
To re-scale:
- Open the Settings app (the gear icon on the desktop).
- Go to the Screen section.
- Select Text Size and Display (in some versions of MIUI, Screen Size may be called Screen Size).
- Move the slider Size of the display left (decrease) or right (magnify).
- Click Ready or Apply to save the changes.
🔹 Important: After the zoom change, the system may suggest rebooting the phone, which is normal. If the interface looks "curved" (for example, icons overlap), go back to the settings and select the default value.

2. Set up font size separate from scale
If you only need to zoom in on text without affecting icon sizes and controls, use a separate font setting, which is useful for users with vision problems or those who read a lot of text on the screen.
Instructions:
- 📱 Open the Settings. → Screen. → Text and display size.
- 🔤 Find the font size slider (usually located below the screen scale settings).
- 📏 Move the slider to increase or decrease the font. values from A (the smallest) to AAA (major).
- 🔄 Changes apply immediately – check readability in messages or browser.
⚠️ Note: Some Xiaomi models (e.g. Redmi Note 10 Pro) POCO X3 Pro) as the font grows as large as possible, the layout in the applications can "move off"; if the text is cut or overlaid on buttons, reduce the size by one division.

3. Gesture scaling (for MIUI 12 and later)
MIUI 12 and above has a gesture zoom feature that allows you to temporarily enlarge part of the screen with triple tap, which is convenient for viewing small details in photos, maps or web pages.
How to turn on:
- Go to Settings → Special Opportunities → Increase.
- Activate the switch Increase with a gesture.
- Set up the parameters: 🔍 Type of enlargement: Select the Full screen or the Window (the latter is easier to read text). 📱 Gesture of enlargement: triple touch or hold with three fingers. 🔄 Maximum scale: adjust with a slider (recommended 2-3)× comfortable-read).
💡 Tip: If the zoom is triggered by chance (for example, during games), disable the function or change the gesture to hold with three fingers - this will reduce the number of false positives.

4. Scale change in browser and applications
Many applications (especially browsers and instant messengers) have their own zoom settings that are independent of system parameters.
4.1 Mi Browser and Google Chrome
To increase text on web pages:
- 🌐 In Mi Browser: Open the menu (three dots in the upper right corner) → Settings → Text and coding → set the font size (for example, a very large one).
- 🔍 In Chrome: tap the icon ⋮ → Settings → Special facilities → Size of text.
- 🖱️ For temporary magnification: Bring two fingers together on the screen (the pinch gesture) to reduce, or dilute to increase.
4.2. Social networks and messengers
In applications like Telegram, WhatsApp or VKontakte, text scales are changed through system settings (see section 2).
- 📧 In Gmail: Settings → General settings → Size of text.
- 💬 In Telegram: press the message → Select Change the text size (available in the latest versions).
💡
If the app doesn't have scale settings, try turning on Settings in system settings → Special Options → Color Correction → High contrast mode. This will make the text bolder and clearer, but it won't change its size.
5. Solving blur screen issues after scale change
Sometimes, when you zoom in or change the size of the font, the interface elements become blurred and the icons pixelated, because the system doesn't properly handle the zooming for the current screen resolution. Here's how to fix the problem:
| Problem. | Reason. | Decision |
|---|---|---|
| Blurred text on the menu | Disparity between screen resolution and scale | Return the scale to Default and restart the phone |
| Pixel icons. | Too big a scale for low resolution | Reduce the scale by 1-2 divisions or turn off animation in Settings → About Phone → Additional → Windows animation |
| The elements overlap. | Mistake of rendering in MIUI | Clear the system cache: Settings → Annexes → Application management → ⋮ → Show system-based → Settings → Warehouse → Clear the cache |
| Black stripes on the edges of the screen | Wrong aspect ratio | Check the screen settings in Settings → Screen → Screen resolution and select the recommended value |
⚠️ Note: If the slurring has appeared after the update MIUI, Try resetting the screen to factory settings. → System system → Resetting settings → Reset the screen settings. This operation will not delete your data, but will return all display parameters (brightness, scale, color scheme) to the standard ones.
6. Hidden scale settings for power users
If standard methods do not give the desired result, you can use the development settings or ADB commands. These methods are suitable for advanced users and require caution.
6.1.Pixel density setting (DPI)
The DPI (dots per inch) setting determines how many pixels fit per inch of the screen, which allows for more precise zoom control, but can lead to incorrect display of some applications.
How to change the DPI:
- Activate Developer Mode: Go to Settings → About Phone and tap MIUI Version 7 times.
- Back to Settings → Additionally. → For developers.
- Find Minimum Width (the equivalent of DPI settings) and the standard value is 360dp or 411dp.
- Change the value (e.g. 320dp to zoom in on items or 480dp to zoom in) and restart the phone.
📌 Recommendations on values DPI:
- 📱 For the Redmi Note 11 (FHD+): 380–420dp
- 📱 For POCO F4 (AMOLED): 400–440dp
- 📱 For Xiaomi 13 (2K-screen: 440–480dp
💡
Changing the DPI can disrupt some applications (such as banking or gaming) and back up your data before experimenting.
6.2. ADB commands for fine-tuning
If you have access to the Android Debug Bridge (ADB), you can zoom in via the command line, which is useful if the system settings are locked.
Example of commands to change DPI:
adb shell wm density 400Where 400 is the desired DPI value. To return the standard value, use:
adb shell wm density reset⚠️ Attention: Misuse of the right ADB This can cause a phone malfunction, if you change it. DPI The screen has turned black or the phone does not respond to touch, connect it to the PC and execute a reset command (see above).
