Font Scaling
Set a specific scale for text in your app that is styled using relative units and ignore the device setting. e.g. Set 100% to force the default size or set 90% for smaller text than default.
Users may set a Font size on their Android device which will then be reflected when your website is displayed within your Android app (as well as in a standard browser, such as mobile Chrome). CSS rules that use relative units like em
, rem
, or %
will be scaled according to the device setting. However, note that if you use absolute units such as px
units for font sizes, they generally won't scale based on the device's font size settings in Android.
The Font Scaling setting applies a specific scale to your app, independent of the deviceโs system settings. To force a default or unscaled version, set the Font Scaling setting to 100%.
