Change Web Text Size in the Browser App auf OnePlus
The browser app renders every web page at 100 percent text size by default. This works fine for most sites, but articles with small fonts or pages designed for desktop screens often stay hard to read even after you zoom in manually.
OnePlus phones on OxygenOS include a text scaling slider built into the browser settings. It changes how large body text appears on pages, independent of the general system font size in Android. To reach it, open Chrome app ➔ menu ➔ Settings ➔ Accessibility. Swipe the slider left or right to set your preferred scaling, anywhere up to 200 percent.
Some websites use fixed layouts that block zooming and scaling entirely. If moving the slider has no visible effect, check that Force enable zoom is turned on in the same Accessibility menu. Without it, the page keeps its own font size regardless of your setting.
Text scaling only affects how the browser app displays web content. It does not change font size in other apps or in Android system menus. If you want larger text everywhere on the phone, adjust the system font size in the general display settings instead.
Pushing scaling close to 200 percent can break the layout on some pages, causing buttons or menus to overlap text. If that happens, lower the value a few steps until the page looks correct again.
