Small text in Telegram on the Xiaomi screen makes you squint? Let's figure out how to increase the font in the messenger - from the standard settings of the application to the hidden capabilities of MIUI. The problem is especially relevant for users of smartphones with high resolution screen (for example, Xiaomi 13 Ultra or POCO F5 Pro), where by default the text may seem too miniaturized.
In this article, you will find 5 proven ways – from basic to advanced, including changing the system scale, setting up chat in Telegram and even using third-party themes. We took into account the features of the latest versions of MIUI 14/15 and the current Telegram (2026), so the instructions will work on most Xiaomi, Redmi and POCO devices.
Important: Some methods require a smartphone reboot or temporarily change the display in all apps. If you need to enlarge the font only in Telegram, focus on the first two sections.
1. Enlarge the font through Telegram settings
The easiest way is to use the built-in messenger options. Telegram allows you to change the text size regardless of the MIUI system settings, which is convenient if you do not want to touch other applications.
Open Telegram and follow the following steps:
- 📱 Slip along three horizontal lines (menu) in the upper left corner.
- ⚙️ Select Settings → Appearance.
- 🔍 Scroll down to the font size block.
- 📏 Move the slider to the right to enlarge the text. Values available from Small to Very Large.
The changes are instantaneous – no restarting of the app is required – this method works on all versions of Telegram (including Telegram X) and does not affect Xiaomi’s system settings.
💡
If after changing the font size in Telegram, the text in chats became blurry, try to enable the option to smooth fonts in the same appearance settings.
2. System-scale change in MIUI
If Telegram's built-in options aren't enough, you can zoom in on the operating system level, and it will affect all apps, but it will have a more noticeable effect.
Instructions for MIUI 14/15:
- Open the Settings → Screen.
- Select Text Size (or Font Size in Older Versions).
- Move the slider to the right. The values available are Small (S) to Very Large (XXL).
- Confirm the changes by clicking on Ready.
After settings, MIUI may suggest rebooting the device. If the text gets too large, go back to this menu and reduce the value. Note: some models (Xiaomi 12T, Redmi Note 12 Pro+) may crop interface elements in applications at maximum scale.
3. Use of themes with large print
Telegram supports custom themes, some of which include enlarged text, a solution that is suitable for those who want to not only resize the font, but also personalize the appearance of the messenger.
How to install a topic with a large font:
- 🎨 In Telegram go to Settings → Appearance → Topics.
- 🔍 In the search bar, type in queries such as big font, large text or large font.
- 📥 Choose your favorite theme and click Apply.
- 🔄 If the font is still small, combine the theme with the first method (increase through Telegram settings).
Popular topics for large text:
| Title of the topic | Author | Features |
|---|---|---|
| BigFont Dark | @telegram_themes | Dark theme with a 30% larger font |
| Large Text Blue | @miui_themes | Blue accent, font +40% |
| Xiaomi SuperSize | @xiathemes | Optimized for MIUI, font +25% |
| Minimal Big | @minimal_themes | Minimalist design with large monowire text |
⚠️ Note: Some topics may conflict with animations MIUI, If Telegram starts to lag after applying the theme, return the standard appearance.
4. Scaling setup in Developer Mode
For advanced users, there's a way to fine-tune the scale through developer mode, which will allow you to zoom in the font more than you would in standard MIUI settings.
Algorithm of action:
- Activate Developer Mode: Go to Settings → About Phone. Tap 7 times on MIUI Version. Enter the unlock password if necessary.
Settings → Additional → For Developers
Minimum width
Smallest width
400dp
420dp
Reboot your smartphone.
This method affects all applications, including Telegram. If the interface becomes uncomfortable after the changes, return the value of 360dp (the standard for most Xiaomi).
What if the interface elements are lost after the scale change?
5. Third-party applications for font enlargement
If the built-in methods don’t work, you can use third-party utilities, for example, the Big Font app (available on Google Play) allows you to zoom in text selectively for individual programs, including Telegram.
How it works:
- 📥 Install Big Font from the official store.
- 🔧 Grant the application rights Special features (in settings) MIUI).
- 🎯 In the list of applications, select Telegram.
- 📏 Set up the font size and style (greater, italic, etc.).
⚠️ Note: Apps for changing the font may conflict with MIUI, Especially on firmware with enhanced protection (for example, Xiaomi) EU ROM). Before using, back up your data or check for compatibility reviews with your smartphone model.
On devices with a Snapdragon 8 Gen 2 processor (such as the Xiaomi 13 Pro), third-party scaling utilities can cause overheating during prolonged use.
Comparison of methods: which one to choose?
To make the choice easier, we have collected the key features of each method in the table:
| Method | Impact on other applications | Maximum increase | Difficulty | Reboot required |
|---|---|---|---|---|
| Telegram settings | ❌ No. | ⭐⭐ (before +50%) | ⭐ (simple) | ❌ No. |
| MIUI System Scale | ✅ Yes. | ⭐⭐⭐ (before +100%) | ⭐ (simple) | ✅ Yes. |
| Castomy themes | ❌ No, only Telegram) | ⭐⭐⭐ (before +70%) | ⭐⭐ (middle-class) | ❌ No. |

| Third-party annexes | ⚠️ Selectively | ⭐⭐⭐⭐ (before +200%) | ⭐⭐⭐ (difficult) | ❌ No. |
For most Xiaomi users, the best solution is a combination of the first and second method: first increase the font in the Telegram settings, and then adjust the system scale in MIUI if necessary.

Frequent problems and solutions
When changing the font size in Telegram to Xiaomi, there may be errors. Let's consider the most common and ways to fix them.
Problem 1: After the font increase in Telegram, the emojis in the keyboard disappeared.
Solution: This is a bug in some versions of MIUI. Return the standard font size in the messenger settings, restart the app and try again. If the problem persists, upgrade Telegram to the latest version.
Problem 2: System scale is lost after the MIUI update.
Solution: This is due to the policy of resetting some parameters for large updates. After updating, reset the desired font size in Settings → Screen → Text Size.
Problem 3: Some chat rooms display text finely despite settings.
Solution: This may be due to individual chat settings. Open a problem dialog, tap the name of the person involved → Change → Font size and set the value manually.
💡
If the font in Telegram remains small after all the manipulations, check if the system has restrictions for high-resolution applications (for example, in charge saving or performance settings).
