Change Webpage Text Size in Mi Browser auf Xiaomi
Web pages in Mi Browser use their own text size setting, separate from the system font size found in your general display settings. That is why changing the font size on your home screen has no effect on how websites render.
Mi Browser offers five levels: Tiny, Small, Normal, Large and Huge. Tiny fits more content on screen but can be hard to read on small displays. Huge makes text easier to read but breaks the layout on some sites and forces more scrolling.
How to change it
Open Mi Browser ➔ tap Profile ➔ tap Settings ➔ tap Webpage text size ➔ choose one of the five levels.
The new size applies immediately to any page you load afterward, including tabs already open once you refresh them. If a site still looks unreadable after switching to Huge, the page itself may use a fixed layout that ignores browser font scaling. In that case, use the browser zoom controls instead, or switch to reader mode if the site supports it.
This setting only affects Mi Browser. If you use a different browser app, look for a similar font size option in that app's own settings.
