Android : Get the size of my widget

I just want to know how big my current widget is. I found tons of questions to set the minimum size, but I don't want to set it. Instead I want to show that informations which simply fit on the widget.

If the widget is too small I need to hide some things, but I need to know the size for that. I read the source code of some classes like the AppWidgetProvider, even the documentation. There are allways just references about the minimum or maximum size, but never the current size.

Please point me to the right ressource.
