How to increase the font on Xiaomi Redmi 10: all the ways from system settings to hidden features

Why do Redmi 10 users want to change the font size?

Xiaomi Redmi 10, with a 6.5-inch screen and FHD+ resolution (2400×1080), offers great detail, but standard text sizes can seem too small — especially for users over 40 or in bright sunlight. According to a Vision Council study, 65% of smartphone owners have at least once faced the need to increase the font for comfortable reading.

The problem is compounded by Xiaomi’s MIUI, which uses high-resolution MiSans by default, and can make text in instant messengers, browsers or settings seem “blurred” or hard to read. Fortunately, Redmi 10 has at least 5 ways to zoom in on the font, from basic system tools to hidden features for individual applications.

In this article, we will discuss:

• 🔍 Standard scaling settings in MIUI (It works on all versions of the firmware).
• 📱 Change the font size for specific applications (Telegram, Chrome, WhatsApp).
• 🛠️ Hidden features for users with poor vision (high contrast mode, magnifier).
• ⚙️ Solving problems when the font does not change or resets after rebooting.

1. In the same menu (Text Size and Display) select Screen Size.
2. Try the values Large or Very Large – they will increase not only the text, but also all graphic elements.
