How to increase the font on Android Xiaomi

Modern Xiaomi smartphones are equipped with high-resolution displays, which ensures clear images, but sometimes the standard text size seems too small for comfortable reading. This is especially true for users with impaired vision or those who spend a lot of time reading articles and chatting in instant messengers.

Fortunately, the shell MIUI and the new HyperOS provide flexible tools for customizing the interface. You can not only make the letters larger, but also change their style, making the text bolder and more contrasting. In this article we will look at all the ways to customize typography on devices Redmi and Poco.

Changing display parameters does not require root access or installing third-party software. All necessary functions are built into the “Settings” system menu. Let's take a closer look at how to adapt the screen to your individual needs.

Basic font size adjustment in the menu

The easiest and most obvious way to change the letter size is in the standard system settings menu. This method works on all current firmware versions, from MIUI 12 to the latest HyperOS. The interface here is intuitive and allows you to visually evaluate changes in real time.

First, you need to open the main menu and find the section Settings. Next, scroll down the list to Screen (or “Display” in some localizations). This is where all the parameters related to brightness, color temperature and, of course, are concentrated text size.

Inside the "Screen" menu you will see an option Text size. By clicking on it, you will be taken to a screen with a slider-controller. By moving it to the right, you will increase the font scale throughout the system: in menus, messages, browser and settings.

Please note that at maximum zoom, some interface elements may not display correctly or extend beyond the screen. The system usually warns about this, but a visual check will not be superfluous. After setting the desired value, simply go back - the changes are applied instantly.

⚠️ Attention: With extremely large fonts, buttons in some applications may overlap with text. If you notice malfunctions in the operation of a particular software, try reducing the size by one division.

Activating large text mode for the visually impaired

If the standard slider is not enough and you need a really huge font, smartphones Xiaomi have a special mode. It is intended for people with severe visual impairments and changes the logic of displaying interface elements more radically.

To activate this function, return to the main settings menu and go to the Advanced settingssection. Here you need to find the item Special. capabilities (sometimes called “Special Features”). Inside this section we are interested in the tab Vision.

Find the switch Large text and activate it. The system may request confirmation of the action, since enabling this mode significantly changes the layout of many screens. After confirmation, the font will become as large as possible, and the spacing between lines will increase.

It is important to understand that this mode affects not only the size, but also the location of icons and buttons. Some menus may become one-page to accommodate larger items. This is the price for maximum readability.

Adjusting font weight and styles

In addition to size, character saturation plays an important role. Thin letters in bright sunlight or poor lighting can blend into the background, making them difficult to read. The shell MIUI allows you to make the font bold, which significantly increases the contrast.

The option to change the style is usually located in the same menu where you adjust the size. In the Screen → Text size section there is often a separate switch Bold font. In some firmware versions, it is placed in a subsection Advanced inside the font menu.

Enable This option redraws all system fonts, making them denser. This is especially useful for older users or for those who use phones with low-resolution panels, where thin lines may look blurry.

Also in the theme store MIUI you can download third-party fonts with pre-increased boldness or a specific style. To do this, go to the application Themes, go to your profile and select the section Fonts. There you can find options optimized for better readability.

⚠️ Attention: Third-party fonts from the theme store may not display correctly in some banking applications or instant messengers. If you notice “squares” instead of letters, return the standard system font.

Increasing the scale of the entire image (DPI)

Sometimes users need to enlarge not only the text, but also all interface elements: icons, buttons, input fields. The standard font slider doesn't do this. To solve this problem, there is a minimum width setting or DPI (dots per inch).

This function is hidden in the menu for developers. To get there, go to Settings → About phone and quickly click 7 times on the item MIUI version (or OS version). A notification will appear indicating that you have become a developer.

Now return to Advanced settings → For developers. Find the item Minimum width (or “Smallest width”). Remember the current value! This is critical for the ability to rollback changes.

The standard DPI value is usually 360, 392 or 411 depending on the model.

To increase the scale of the entire interface, reduce the DPI numeric value. For example, if your value is 392, try setting it to 320. The lower the number, the larger all objects on the screen will be. Do not set the values ​​too low (less than 300), otherwise the interface may become unusable.

What to do if the screen becomes unusable after changing the DPI?

If you set the value too low and cannot click anything, try quickly connecting the mouse via an OTG cable and changing the value back. If there is no mouse, reboot the phone into safe mode (by holding down the power button), where the settings are reset, or reset the settings via Recovery.

Comparison of display settings methods

Various methods for enlarging text have their own advantages and disadvantages. The choice of a specific method depends on how severely the user’s vision is impaired and what tasks he solves on a smartphone. Below is a table to help you decide on the best option.

The standard slider is the safest method, as it has been tested by engineers Xiaomi on all models. The mode for the visually impaired gives the maximum size, but breaks the layout. Changing DPI affects all elements, but requires caution.

Adjustment method	Icon impact	Text impact	Complexity
Size slider	Does not change	Increases	Low
Large text mode	Changes location	Increases greatly	Low
Bold	Does not change	Makes it saturated	Low
Change DPI	Increases	Increases	Average

Combining these methods allows you to achieve an ideal result. For example, you can slightly increase the size with the slider, add some fat, and slightly lower the DPI. The main thing is to find a balance in which the information is easily perceived, but the functionality of the phone does not suffer.

Solving display problems after configuration

After global changes, visual artifacts may occur in the system. Sometimes text overlaps images, buttons become unclickable, or part of the menu gets cut off. This is a normal reaction of an adaptive interface to non-standard parameters.

If you are faced with the fact that the text in a particular application has become unreadable, try clearing the cache of this application. Go to Settings → Applications → All applications, select the problematic app and click Clear → Clear cache.

In rare cases, rebooting the device helps. Restarting the system forces the interface to recalculate all display parameters taking into account the new font and pixel density settings. This simple action often eliminates minor layout glitches.

If all else fails and the phone has become impossible to use, you will have to reset the screen settings. In the menu For developers you can find the item Reset design settings (if available) or simply return the DPI value to the original one that you wrote down earlier.

⚠️ Attention: The interface and names of menu items may vary slightly depending on the version of MIUI or HyperOS. If you do not find the described item, use the search in the settings (magnifying glass icon at the top of the screen).

Frequently asked questions (FAQ)

Is it possible to increase the font in only one application, for example, in Telegram?

In most cases, a global phone setting affects all applications at once. However, some apps, such as Telegram or WhatsApphave their own internal font size settings. Go to the settings of the application itself and look for the “Chat” or “Design” section; there is often a separate slider there.

Why did some settings disappear after increasing the font?

When the text is greatly enlarged, interface elements may not fit on the screen. In the shell MIUI some of the items may be hidden or require horizontal scrolling, which is not always obvious. Try reducing the font by one division or turning the phone to landscape mode.

Does a large font affect battery consumption?

The font size itself has virtually no effect on power consumption. However, using high contrast or color inversion modes (if you enabled them in special features) may slightly increase power consumption on AMOLED screens due to pixel performance.

How can I return all the settings to the way they were if I get confused?

The fastest way is to go to Settings → Advanced settings → For developers and check the “Minimal” value width". Also turn off the “Large Text” mode in the “Special” section. capabilities" and reset the font size slider in the "Screen" menu to the middle position.
