How to increase the size of letters on the keyboard Xiaomi Redmi: all working methods

Why the small print on the keyboard prevents you from using a smartphone

Small letters on the Xiaomi Redmi keyboard are a common problem, especially for users with visual impairments or those who are used to large text on previous devices. In the MIUI shell, the default font size of the keyboard is often smaller than in standard Android, which creates discomfort when typing, searching or working with documents.

Unlike the system font, which changes in the display settings, the size of the letters on the keyboard is adjusted separately โ€” and it is not always obvious where to look for these parameters. In addition, Redmi can have different keyboards: standard from Xiaomi (Mi Keyboard), Gboard from Google or third-party applications like SwiftKey. Each of them has its own settings, which makes it even more difficult to do.

In this article, we will discuss all the current ways to increase the font, from basic settings to hidden developer parameters, learn how to scale letters without losing the functionality of the keyboard, and what to do if the desired options suddenly disappeared after the MIUI update.

Method 1: Resize the font in the settings of the standard Mi Keyboard

If your Redmi uses the Mi Keyboard (the default keyboard on most models), the easiest way to do this is to use the built-in settings.

  1. Open any application where the keyboard appears (such as Messages or Notes).
  2. Touch the gear badge (โš™๏ธ) on the keyboard panel to open its settings.
  3. Go to the Topics and layout section โ†’ Keys size.
  4. Move the slider Text size to the right to enlarge the font. Here you can adjust the height of the keys (keyboard height).

โš ๏ธ Note: Some Redmi models (e.g. Redmi Note) 11/12) Text size may not be on this menu, so try the method. 2 or 3.

Update your keyboard in Google Play (if itโ€™s updated)

Make sure you use the latest version of MIUI.

Check if a third-party theme is installed that blocks settings-->

Method 2: Scaling through special features settings

If the standard keyboard options don't work, you can use system scaling, which will not only increase the font on the keyboard, but also other interface elements, and is suitable for Redmi on MIUI 12-14:

  1. Open Settings โ†’ Special features โ†’ Visual corrections.
  2. Select font size and move the slider to the right. The Huge option will zoom in as much as possible.
  3. Go back and activate the display scale โ€“ this will further increase the size of the keys.

๐Ÿ”น Important: After zooming, some applications (such as games or banking services) may not display correctly, in which case return the settings to default values or use Forced Scaling mode in the developer settings (see Method 5).

ParameterMinimum valueMaximum valueRecommendation
Type sizeSmall-timeHuge.Optimal: Large
Scale of displayBy default.150%Do not exceed 125% to avoid bugs
Contrast of typeLow.Tall.Insert for better readability

Method 3: Configure the font in Gboard (keyboard from Google)

Many Redmi users install Gboard instead of the standard keyboard for its advanced features, in which case the font change algorithm will be different:

  1. Open any text box to allow the Gboard keyboard to appear.
  2. Click on the tri-point icon (โ‹ฎ) in the top panel and select Settings.
  3. Go to the topics โ†’ Set up the topic โ†’ Text.
  4. Choose the font size: Normal, Large or Large.

๐Ÿ’ก Helpful tip: Gboard can also change the color of the text and the style of the keys, which will improve visibility, for example, dark letters on a light background read better than the standard scheme.

Gboard by Google

SwiftKey or other third-party

  • ๐Ÿ” If Text is not available: Update Gboard to Google Play or reinstall the app.
  • ๐ŸŽจ Additional settings: In the Topics section you can download special themes with enlarged keys (for example, "Big Keys").
  • โš™๏ธ Resetting: If the font went off after the update, return the settings to the factory in Additional โ†’ Reset the settings.

Method 4: Using third-party keyboards with large font

If the built-in settings don't suit, consider alternative keyboards that were initially optimized for visually impaired users.

  • ๐Ÿ“ฑ SwiftKey: Allows you to select font size in the theme settings (Settings) โ†’ Topics โ†’ Set up โ†’ Text size: Supports gestures and predictable input.

๐Ÿ”ง How to install a third-party keyboard:

  1. Download the app from Google Play (like SwiftKey).
  2. Open Settings โ†’ System and device โ†’ Language and input โ†’ Current keyboard.
  3. Activate the new keyboard and set it by default.
How to return a standard keyboard if the third-party is unstable?
1. Open Settings โ†’ Applications โ†’ Application Management. 2. Find a third-party keyboard (like SwiftKey) and click Disable. 3. In the input settings (Language and Input), select Mi Keyboard or Gboard as the default keyboard. 4. Reboot the device if the changes don't apply immediately.

Method 5: Hidden Developer Settings for Forced Scaling

If none of these methods worked, you can use the developer mode, which will force all interface elements, including the keyboard, to scale, and be careful, if you make the wrong settings, you can crash the system.

๐Ÿ›  Instructions:

  1. Activate Developer Mode: Go to Settings โ†’ About Phone and click on MIUI Version 7 times.
  2. Back to Settings โ†’ Additionally. โ†’ For developers.
  3. Find the option Minimum width (in dp) and set the value 400-450 (the larger the number, the larger the elements).
  4. Activate Forced Scaling Enablement (if option is available).
  5. Reset the device.

โš ๏ธ Note: Changing the minimum width to values above 480 dp may cause applications to display incorrectly (for example, banking programs may refuse to run). If you have problems, return the value to 360 dp (standard for Redmi).

๐Ÿ“Œ Key takeaway: Developer mode is a powerful tool, but it's only worth using if other ways haven't worked. After changing your settings, check the key applications (messengers, banking, camera).

Method 6: Manually modifying system files (for advanced users)

This method is only suitable for advanced users, as it requires root rights or the use of ADB. It allows you to change the font size at the system file level, but if you do not act correctly, it can lead to data loss or a โ€œbrickโ€ of the device.

๐Ÿ”น Instructions for users with root:

  1. Install a file manager with root support (such as Root Explorer).
  2. Go to /system/fonts/ or /system/etc/ (depending on the MIUI version).
  3. Find the keyboard font files (usually called LatinIME.ttf or MiKeyboard.ttf).
  4. Replace them with a large sized version (you can download them on thematic forums, for example, XDA Developers).
  5. Reset the device.

๐Ÿ–ฅ Instructions through ADB (rootless):

adb shell settings put system font_scale 1.3


adb reboot

This command will increase the system font by 30 percent, and for the keyboard, the effect can be partial.

โš ๏ธ Warning: Changing system files without backup is fraught with constant failures. Create a backup through Settings before experimenting โ†’ Additionally. โ†’ Backup and reset or by TWRP (if established).

Frequent problems and their solutions

When changing the font size on the Xiaomi Redmi keyboard, users face typical difficulties.

  • โŒ Problem: After the update MIUI Solution: Return the settings manually (see method 1 or 3) or reset the keyboard to factory settings in its settings.
  • โŒ Problem: Large font is cropped on keys. Solution: Reduce font size by 1 point or increase keyboard height in settings.
  • โŒ Problem: Some apps (like VKontakte) display the keyboard finely, others fine. Solution: That's the limitation of the app itself. Try using Gboard or SwiftKey -- they often ignore such limitations.

๐Ÿ”„ If nothing works: Reset the keyboard to the factory or reinstall it:

  1. Open Settings โ†’ Applications โ†’ Application Management.
  2. Find your keyboard (such as Mi Keyboard or Gboard).
  3. Click Warehouse โ†’ Clear the data and Reset the settings.
Can you zoom in on the keyboard without affecting the rest of the interface?
Yes, but only if your keyboard supports separate font settings (like Gboard or SwiftKey) with the standard Mi Keyboard on some versions of MIUI, this option is not available, and you have to scale the entire interface through Special features.
Why did the emoji or stickers on the keyboard disappear after the font enlargement?
This is a bug in some versions of MIUI that is associated with overflowing keyboard memory. Solutions: Clear the keyboard cache in Settings โ†’ Applications. Reduce the font size by 1-2 points. Reinstall the keyboard.
How to return the standard font size if the keyboard became uncomfortable after the changes?
Open the keyboard settings and reset the font settings to the default values. If you use Special Options, return the font size slider to the middle position. font_scale 1.0
Is this a good idea for POCO or Black Shark?
Yes, because these devices also run on MIUI (or its modifications like the POCO Launcher), except for pure Android One models (like the Mi A3), where the settings may differ.
Can I change the keyboard font without installing additional applications?
Yes, if you have MIUI 12-14. Use method 1 (Mi Keyboard settings) or method 2 (special features). Older versions may require Gboard or manual editing of system files.
