Google recommends keeping your font sizes set with SP so that the UI settings will modify the font sizes within your application. Are you using SP?

I believe that using DP or PX or something else will cure your issue. Keep in mind that this is not recommended for Accessibility purposes.

For a complete list of possible text size types, see http://developer.android.com/reference/android/util/TypedValue.html

Here they are:

COMPLEX_UNIT_DIP - TYPE_DIMENSION complex unit: Value is Device Independent Pixels.
COMPLEX_UNIT_IN  - TYPE_DIMENSION complex unit: Value is in inches.
COMPLEX_UNIT_MM  - TYPE_DIMENSION complex unit: Value is in millimeters.
COMPLEX_UNIT_PT  - TYPE_DIMENSION complex unit: Value is in points.
COMPLEX_UNIT_PX  - TYPE_DIMENSION complex unit: Value is raw pixels.
COMPLEX_UNIT_SP  - TYPE_DIMENSION complex unit: Value is a scaled pixel.

Also: Note that not all of these options are available from an xml file and that some of these settings may only be used programmatically (at least that's what I recall).
