How to change the font size on Xiaomi phone: a detailed guide

Owners of Xiaomi, Redmi and POCO smartphones often face the need to personalize the interface of the device to their individual needs. One of the most popular features is the ability to change the size of the font on the screen, which directly affects the convenience of reading news, correspondence in instant messengers and working with documents. In modern shells MIUI and HyperOS, this setting has become more flexible and thoughtful, allowing you to achieve perfect readability of the text without compromising the overall interface.

Standard settings may not be suitable for visually impaired users or, conversely, those who prefer to see the maximum amount of information on the screen at the same time. Scaling interface elements is not just a cosmetic change, but an important aspect of ergonomics that reduces eye strain with prolonged use of the gadget. In this article, we will discuss in detail all available ways to change the size of text, including hidden opportunities for advanced users.

Before we get into the settings, it’s worth noting that changing the text display settings affects the entire system, which means that the size will be applied to menus, notifications, the browser and most third-party applications that support Android system standards. Sometimes after making changes, you need to restart the device or restart the interface to correctly apply all the edits.

Standard font settings in MIUI and HyperOS

The main way to change text settings in Xiaomi smartphones is through the system settings menu. The developers have taken this tool to an easily accessible place so that anyone can quickly adapt the screen to themselves. First, you need to unlock the device and find the Settings icon on the desktop or in the notification curtain.

Then you go to a section that can be called differently depending on the firmware version, but most often it's a Screen or a Display item, and inside that menu is a text size subsection, where the main magic happens, and you'll see a slider that you can move around and pick from five preset values, from the smallest to the largest.

It’s important to understand that changing the size of text also affects the scaling of some interface elements, making them larger or smaller, especially in the settings menu and system applications such as Contacts or Messages.

💡

Before changing the settings, take a screenshot of the current state of the screen so that if necessary, you can visually compare the result and return everything as it was.

Once you select the desired size, the system will automatically apply the changes. If you use HyperOS, the resizing animation can be smoother and accompanied by a visual preview in real time. In older versions of MIUI, confirmation of action may be required.

Advanced settings: changing the screen scale

Often, it's not enough for users to zoom in, but to zoom in on everything that happens on the screen. In Android, and in particular in the Xiaomi shell, that's what you do with "UI Element Size" or "Scream Size," and you can find it in the same place as the font settings, usually right under the text size slider.

This feature allows you to make all the elements — icons, buttons, input fields and the texts themselves — larger or smaller without changing their proportions. It is a useful tool for people with poor vision, who are not enough to standardize font zoom, and when you zoom in, you put more content on the screen, which is convenient when working with tables or reading long articles.

It is worth noting that aggressive zooming can lead to incorrect display in some applications that are not optimized for non-standard resolutions, in which case the layout can go, and the buttons become non-clickable.

To access these settings, follow the following steps:

• 📱 Open Settings and go to the Screen section.
• 🔍 Find the Size of Interface Elements (or "Scale").
• ⚙️ Move the slider to the desired position by watching the changes at the top of the screen.
• ✅ Confirm your choice if the system requests confirmation.

Experiment with the balance between font size and screen scale to find the perfect match for your eyes. Sometimes a small zoom in large print gives a better result than maximizing both parameters.

Using the reading and theme mode

In addition to mechanically zooming in characters, text perception is influenced by contrast and surroundings. Xiaomi smartphones have a built-in Read Mode that not only removes the blue spectrum of radiation, but can also mimic the appearance of e-paper, making text clearer and more pleasing to the eye, especially when reading books.

You can activate this function through the control center or in the screen settings. In advanced reading settings, you can select a texture type (for example, "Book 1" or "Book 2"), which changes the shade of the background and contrast of letters, and this indirectly affects how easy it is for you to read small print without zooming in.

Also worth mentioning is system themes: Some third-party themes from MIUI Themes can force system fonts to be larger or smaller, and installing a theme is a quick way to change the style of text across the entire interface.

⚠️ Warning: Installing themes from unverified sources can lead to unstable system operation or advertising. Use only official themes from the Xiaomi store or trusted authors.

If you like reading from your phone at night, be sure to turn on Dark Theme, which, when combined with large print, significantly reduces the burden on your eyesight. MIUI has Auto Switch, which activates dark mode on a schedule or at a certain level of light.

Set up a font for people with impaired vision

For users with severe vision problems, standard settings may not be enough, and in this case, the accessibility features built into Android come to the rescue, allowing you to zoom in text to giant sizes, making it readable even when you have a lot of visual acuity.

To activate these features, go to Settings → Additional Settings → Special Options (or “Special Features”). Here you are interested in Visuals or Text Size in the accessibility category. Unlike normal settings, you can choose a really huge font size.

Also available in this section is the Screen Magnifier feature, which allows you to zoom in on any part of the screen by double pressing or through a separate button, and it is convenient for a one-time view of small details, maps or photos with text, without changing the global settings of the system.

Using these tools, Xiaomi’s smartphone is accessible to older adults and visually impaired users, and by combining large print, high contrast and a screen magnifier, you can fully adapt the device to your needs.

Hidden opportunities through the developer menu

For advanced users who want to have full control of the display of information, there is a developer menu, where you can change the DPI (dots per inch) — the pixel density, which actually changes the scale of the entire system at the rendering level.

To get to this menu, go to Settings → About Phone and quickly click on the MIUI Version (or OS Version) 7 times. After the notification “You became a developer” appears, you can go back to the main settings menu, open Additional → For developers.

Inside, you need to find Minimum Width (or "Less Width"). The default value is usually around 360-400 dpi. Reducing that number will make all elements larger and zooming in will make them smaller. Be careful: setting a value too low can make the interface unusable.

⚠️ Attention: Change of parameter DPI The developer menu is a system edit, and incorrect values can cause you to be unable to get into the menu to get it back, and in the worst case, you'll need to reset your settings.

This method is useful if standard sliders do not give the desired result or if you want to achieve a unique interface look similar to tablets or, conversely, a smart watch.

Frequent problems and ways to solve them

Sometimes, after updating a firmware or installing a new application, the font settings may get confused or displayed incorrectly. For example, text may become unreadable in certain applications, or the settings may reset by themselves. In such cases, the first thing to do is to check whether the Power Saving mode, which sometimes limits visual effects, is activated.

Another common problem is font incompatibility in third-party applications, where some programs, especially banking or enterprise ones, ignore system settings and use their own font size, and unfortunately, you can't influence this with standard methods, but you can try to resize the screen.

If text starts to dance or bump into each other, try resetting the default font settings, cleaning the Topic app cache or Systems interface also helps, and in rare cases, removing newly installed fonts from the theme store helps.

💡

Most text display problems are solved by simply resetting the screen settings or rebooting the device in safe mode to eliminate the impact of third-party applications.

If the interface is completely unreadable (for example, after experimenting with the DPI), You can try to get into the settings through the voice assistant or use the mouse connection through the OTG-Adapter to visually navigate the screen and return normal values.
