How to increase the font on the keyboard of the Xiaomi phone: all ways

Small print on the keyboard of a Xiaomi smartphone can be a real problem — especially for people with visual impairments or those who are accustomed to large text. Unfortunately, in standard MIUI settings, there is no direct slider to change the size of the characters on the keyboard, but this does not mean that the task is impossible. There are at least 5 working ways to make letters larger, from hidden system functions to installing alternative keyboards with flexible settings.

In this article, we will discuss all available methods, from the simplest (system-scale change) to advanced (manual editing of configuration files for power users), pay special attention to the nuances for different models of Xiaomi, Redmi and POCO, and also warn against common errors that can lead to keyboard failures.

1. Enlarge the font through the MIUI system settings

The most obvious way is to scale the entire interface, which will automatically affect the font size of the keyboard, which works on all Xiaomi smartphones with a MIUI 12-14 shell, but has a side effect: along with the keyboard, all the elements of the system will increase.

• 🖱️ Move the slider to the right to enlarge the font, and we recommend that you stay at 125% or 150%, which can cut off the keyboard if you have a high value.
• 🔄 Reboot your phone to make the changes take effect.

⚠️ Note: Some models (e.g. Redmi Note 10 Pro) POCO X3 Pro) on a scale of more than 130%, keys on the keyboard can overlap. In this case, try alternative methods in the following sections.

2. Adjust font size in Gboard (Google keyboard)

If you use Gboard, you’re lucky to have separate font size settings that are independent of system settings, which is suitable for all Xiaomi models, as Gboard is installed as a third-party app.

2. Touch the badge. ⚙️ (gear) on the keyboard panel to open Gboard settings.
3. Select Topics → Create your own theme.
