How to Increase or Reduce the Size of Letters on Xiaomi Keyboard: A Complete Guide

Small font on Xiaomi keyboard makes it difficult to type, and too large letters occupy half the screen? The problem is familiar to many owners of Redmi, POCO and Mi smartphones β€” especially users with visual disabilities or those who have switched from other brands. In this article, we will discuss all possible ways to change the size of letters on the keyboard, from standard MIUI settings to fine-tuning third-party applications.

It’s important to understand that the font size on the keyboard and the system scale of text are different things. Changing one parameter doesn’t always affect the other. We’ll look at both approaches, and also explain how to get around the restrictions if your Xiaomi model (like the Redmi Note 12 or the POCO X5 Pro) doesn’t support direct key size adjustment.

  2. Select Text Size (or Font Size in Older Versions).
  3. Move the slider to the right for zooming in or to the left for reducing.
  4. Click Ready and confirm the changes.

⚠️ Note: On certain devices (e.g, POCO F4) This parameter can be reset after rebooting. If the scale is back to its original, check for updates. MIUI or use alternative methods from the following sections.
