How to scale on Xiaomi phone: font, interface and DPI

Modern Xiaomi and Redmi smartphones feature high-resolution displays that provide incredible picture clarity, but often result in interface elements and text becoming too small for comfortable reading. Standard font settings provided by the manufacturer in the personalization menu allow you to enlarge letters, but do not change the size of buttons, app icons and indentations in the system windows. This creates a situation where eyes get tired and get on the right button becomes more difficult, especially for users with impaired vision.

To fully adjust the display of content, you need to use the hidden capabilities of the Android operating system, which are hidden in the menu for developers. Changing the smallest width (or DPI) parameter allows you to scale the entire interface globally, making it similar to a tablet or, conversely, more compact. In this article, we will discuss in detail the safe methods of increasing screen elements without disrupting the stability of your device MIUI or HyperOS.

Basic font setting and element size in the menu

The first and safest step available to any user without the risk of breaching the warranty is standard calibration through system settings. Xiaomi provides a flexible tool to resize text that automatically adjusts some interface elements to the selected setting. To do this, go to Settings → Screen and Brightness → Text Size. Here you will see a slider, the movement of which instantly changes the typeface in all supported applications.

However, it is worth considering that simply enlarging the font does not always solve the navigation problem. In some system applications, such as Phone or Messages, changing the size of the letters can lead to incorrect display of the layout if the content was not adapted by the developers.

If the standard magnification isn't enough, you can use the Read Mode feature, or the color inversion, which also affects the perception of information, although it doesn't change the physical scale. It's important to find a balance where text is readable, but there's enough information on the screen to work comfortably.

• 📱 The standard setup path is in the personalization section of the system.
• 👁️ The change in font affects most native Xiaomi apps.
• ⚖️ Do not set the maximum size, as this can break the layout of the menu.

⚠️ Note: With extreme font magnification in standard settings, the OK or Back buttons may move beyond the visible area of the screen. If this happens, use voice control or mouse connectivity to return to normal values.

Activation of Developer Mode for Advanced Settings

To access (true) scale management, you need to unlock the hidden Developer Menu. This is standard Android procedure that doesn't require superuser (Root) rights and is safe unless you change unfamiliar settings. You need to go to Settings. → About the phone and find the line "Version" MIUI» or “OS version».

Click this line quickly 7-10 times in a row. The system will start counting down the clicks and eventually report that the developer mode is activated. Then a new option will appear in the main settings menu, usually at the bottom or in the "Additional" section, in the "Additional" section → For developers (or simply "For developers" at the root of the menu, depending on the firmware version).

Inside this menu, there are a lot of technical parameters that affect CPU performance, USB debugging and animation, and we're interested in the section related to drawing and display. Be careful: changing other parameters, such as the limit of background processes, can lead to unstable smartphone operation.

• 🔑 Activation is made by repeatedly pressing the assembly number.
• 🛠️ Developer menu hidden from ordinary users to avoid accidental errors.
• 🔄 After activation, the new menu appears in the main settings of the system.

⚠️ Warning: Never turn off items associated with Overlay or Hardware Acceleration unless you understand their purpose.This can lead to a black screen or a cyclical interface reboot.

Change the scale with the "Lessest width" parameter

The key tool to scale is the Smallest width, which determines the pixel density (DPI) that the system uses to render the interface. On Xiaomi smartphones, the default value is usually 360, 392 or 411 dpi, depending on the screen diagonal and the resolution of the matrix.

To increase all the elements (buttons, icons, input fields), you need to reduce the numerical value of this parameter. For example, if you have 392, a change of 320 or 300 will make the interface much larger. Conversely, increasing the number will make the elements smaller, which is useful on tablets or large screens to display more content.

Changes are applied instantly, without the need to reboot, you will immediately see how the desktop and the settings menu will be rebuilt. 20-30 units) to evaluate the result and not to make the elements gigantic and unreadable.

• 📉 Reducing the number in the “Less Width” field increases the scale of the interface.
• 📈 Increasing the number makes the elements smaller and more compact.
• ⚡ No reboot is required, changes are visible immediately after input.

⚠️ WARNING: Write down the original value of the parameter before changing! If you set a number too small (like less than 200), the interface may become so large that you can't press the Back button or log in to return it to the way it was.

Table of recommended DPI values for different scenarios

Understanding which value to choose comes with experience, but there are averaged standards that suit most users, and the value of DPI has a direct impact on how much information is placed on the screen and how easy it is to get into it with a finger.

For users with normal vision, who just want to enlarge the elements for comfort, a decrease in the standard value of the standard value is suitable for the user. 10-15%. For people with poor eyesight or using a smartphone as a navigator or e-book, more radical changes are needed.

Below is a table with indicative values for different uses of a Xiaomi or Redmi device.

Use of special opportunities

In the Android operating system, which has a MIUI shell on top of it, there's a separate section for people with disabilities, and you can find zoom in here, which works like a magnifier, and it doesn't zoom in all the time, but it allows you to zoom in on any part of the screen at any time.

You can activate this feature in the Settings menu → Advanced Settings → Special Features → Enlarge. Once turned on, a magnifying button will appear on the screen or triple tap on the screen (depending on the OS version), which is ideal for those who rarely need to consider small details, but the constantly enlarged interface interferes with work.

Also in this section is the “Enlarged Text” option, which force the font in the settings menu and some apps to be larger, ignoring standard restrictions.This can be a useful addition to changing the DPI if standard methods are still lacking.

• 🔍 The “Increase” function works as a temporary magnifier for the screen.
• 👆 Control is carried out by a triple tap or floating button.
• ♿ Separate font size slider for special features menu.

⚠️ Attention: Increase mode can interfere with games or fast scrolling of tape, as a random triple tap will buzz the screen.

Compatibility and application layout problems

Changing the system DPI is an interference with the operating system, so some applications may react incorrectly. Software developers often rigidly prescribe the size of elements in pixels, and when global zooming buttons can "hit" each other, and text can be cropped.

Most often, problems arise in banking applications, messaging apps with custom designs and old games. If you notice that after a zoom change in an important application, the Sign In or Pay button disappeared, you will either have to temporarily return the standard DPI, or look for the interface zoom option in the application settings (if there is one, like in Telegram).

It’s worth noting that on different versions of the MIUI 12, 13, 14 shells and the new HyperOS, the system behavior may differ, and in newer versions of Android, it is better at recounting resources, so the probability of bugs is lower.

• ⚠️ Banking applications may require a return of the standard DPI work.
• 📐 The layout of sites in the browser usually does not suffer, as it depends on the zoom of the page.
• 🎮 In games, the interface can become too large, blocking the review.

⚠️ Note: If after changing the settings, the phone began to warm or brake, return the original value DPI. Some values can create an excess load on the GPU when rendering the interface.

💡

Tip: Before you change the scale settings, take a screenshot of the current screen with the settings. If something goes wrong, you will know the exact number to return, even if the interface becomes unreadable.

In this section, we have collected answers to the most popular questions that users have when trying to customize the screen of their Xiaomi, Redmi or POCO smartphone.

💡

Optimal scale is a subjective concept: Start by reducing the standard DPI value by 20-30 units and gradually adjust it over a few days of use to find the perfect balance between text size and the amount of information on the screen.
