Xiaomi and Redmi smartphone owners often face a situation where standard text display settings seem not flexible enough, especially for models with large screen diagonals, where the default fonts can look excessively enlarged. Users who are used to compact devices or simply prefer a minimalist style often look for a way to make text more compact to accommodate more information on a single screen.
The MIUI-enabled Android operating system provides multiple levels of typography control, not just basic settings that are accessible to everyone, but hidden engineering menus for advanced users. In this article, we’ll break down all the methods available, from simple menu switches to DPI, to allow you to perfectly customize your visual perception of information.
It's worth noting that changing the font size will not only affect messages in SMS or messengers, but also the entire interface of the system. Menus, settings, application names and system notifications will change their appearance, so before making a global change, it's important to understand exactly how each parameter affects the performance of your smartphone.
Basic text size setting in MIUI
The easiest and safest way to change letter size is for all users without having to get root rights or install third-party software. The standard MIUI interface allows you to adjust the font scale to a reasonable extent, which is suitable for most use cases. However, many users do not notice this option, since it is often hidden in the sub-menus of special features.
To start the changes, you need to go to the main settings menu of your device, and you should find the section responsible for personalization or additional system parameters. Depending on the version of the MIUI shell (whether it is 12, 13 or 14), the path may vary slightly, but the logic remains the same.
💡
If you can’t find font settings, search by settings by entering the word “font” or “size” in the search bar at the top of the menu.
Once you enter the menu, you'll see a slider that moves to the left will reduce the size of the characters, and the system will offer a few preset options, from "Little" to "Giant." Choose the minimum value to achieve the desired effect. Changes are applied instantly, allowing you to immediately evaluate the result and, if necessary, adjust the settings.
- 📱 Open the Settings app on the main screen.
- 🔍 Go to the Additional or Advanced Settings section.
- 📏 Select text size or Special Opportunities.
- 📉 Move the slider to the leftmost position for the minimum size.
It's important to understand that the standard regulator changes only the size of the glyphs, not their density. This means that the strings can stay wide enough and the indentations large. To fine-tune it, you'll need to use other methods, which we'll discuss below. Basic tuning is good for quick correction, but it doesn't give you full control over the layout of the interface.
Change in screen density (DPI) for advanced
If standard font reduction isn't enough, you can use a change in screen density, also known as Dots Per Inch (DPI), to determine how many pixels will be used to display one inch of an image. By lowering the DPI, you make the system think the screen is higher resolution, making all the interface elements, including text, smaller.
To access these settings, you need to activate developer mode, which is a hidden partition in Android that is designed to debug applications, but is also useful for ordinary users who want to customize the interface. Be careful: setting a DPI too low can make text unreadable or cause malfunctions in some applications.
To change the DPI, you first need to unlock the developer menu. Go to About Phone and press the MIUI version seven times in a row. After you see a message about a successful activation, go back to the additional settings menu. There will be a new Developer Item, inside which you need to find the Smallest Width option.
Write down the original value before changing! it's critically important that in case of problems you can get everything back as it was.Standard values for modern Xiaomi smartphones
⚠️ Attention: Do not set the value DPI This can cause the system buttons to become too small to press, and the interface of some applications to go or become unreadable.
Set up the font in the application Messages
Often, users don't want to shrink the font across the system, but specifically in the Messages app or popular messengers. In the standard Google Messages or MIUI SMS application, the font settings are usually system-specific, but some versions of shells have separate regulators.
Google Messages, which is often pre-installed on Xiaomi’s global versions, doesn’t have a separate font size setting. The app automatically adjusts to the system text size set in the Screen section. If you’ve changed the system font to a minimal one, but it still seems big in the messages, there may be a problem with the design theme you’ve chosen.
The themes in MIUI can redefine system styles, some of which are designed specifically for people with poor eyesight and have enlarged fonts, ignoring the general settings, in which case the solution would be to change the theme to a standard one or search for a topic marked "Compact" or "Small text".
Why does the font not change in some applications?
For users who care about every pixel of space in correspondence, it is recommended to use alternative clients for messaging or to move to a dark topic that visually makes fonts less massive, and it is also worth checking whether the mode “Enlarged Text” is included in special features that can force the content of dialogues.
- 📩 Open the Messages app and click on the profile avatar.
- 🎨 Go to Settings. → Communications.
- 👁️ Check if the high contrast mode is activated.
- 📱 Make sure the system font is set to a minimum value.
Use of third-party launchers
If MIUI system constraints don’t work, third-party launchers come to the rescue. Launcher is a program that replaces the standard desktop and app menu. Popular options like Nova Launcher, Lawnchair or Microsoft Launcher offer flexible font size settings for shortcuts and widgets regardless of system settings.
Installing the launcher requires no complicated manipulations, download the app from the Google Play Store, install it and select it as the default app for the Home screen, and then you get access to an extended settings menu where you can adjust the signature font size of icons, often the largest element on the screen.
However, it is worth remembering that launchers only affect the desktop and app menus. Inside settings, messages and other system sections, the font will remain the same unless the global settings of Android have been changed.
| Launcher | Flexibility of setting | Impact on the battery | Difficulty |
|---|---|---|---|
| Nova Launcher | Tall. | Low. | Medium |
| Lawnchair | Medium | Very low. | Low. |
| Microsoft Launcher | Medium | Average. | Low. |
| Smart Launcher | Tall. | Low. | Tall. |
When choosing a launcher, pay attention to its compatibility with your version of Android. Some older versions may not work properly on new Xiaomi smartphones with a MIUI 13/14 shell, causing lags or improper display of animations. It is recommended to test several options to find the optimal balance between functionality and performance.
Compatibility and scalability issues
When fonts are aggressively reduced and DPIs are changed, users may encounter display artifacts. Some applications, especially banking or corporate ones, may incorrectly scale their interfaces; buttons may move off screen; and text may overlap, making it impossible to use the program.
This is because app developers test their products at standard density values. Going beyond standard values (usually 360-480 dp) is considered a non-standard scenario, in which case only returning to the original DPI values or using compatibility mode, if it is available in the settings of a particular application, helps.
💡
Changing DPI is a powerful tool, but it acts globally on the entire system, unlike the type setting that affects text in the first place.
Also worth mentioning are the readability problems on low-resolution screens. If you have a budget Redmi model with an HD+ screen, a strong font reduction can cause letters to become too thin and blurry (the “ladder effect”). On the AMOLED screens of Xiaomi’s flagship models, this effect is less noticeable due to the high pixel density.
⚠️ Attention: After shift DPI Some widgets may disappear from the desktop or stop updating. That's OK -- just remove the old widget and add a new one after you change your settings.
Comparison of methods and final recommendations
To sum up, for most users, standard text size settings are enough, a safe method that is guaranteed to keep the interface intact and provide comfortable reading, ideal for those who just want to make room for the screen a little while without going into the technical wilds.
The DPI-altered method is designed for power users who know exactly what they're doing, and it maximizes the reduction effect of making a smartphone look like a compact tablet with a lot of information per inch, but the risk of getting into layout bugs is much higher.
The use of launchers is a compromise option that allows you to put things in order on the desktop without affecting the deep settings of the system. This is the best choice for those who are annoyed only with large text under the icons, but satisfied with the standard look of menus and settings.
☑️ Checklist before change DPI
When choosing a method, focus on your needs and device model. On modern Xiaomi with quality screens, experiments with DPI are most successful, whereas on older models it is better to limit yourself to standard means. Remember that the main thing is the comfort of your eyes, not maximum density of information.
