I'd had a similar problem and solved it in the Fragment callback onViewCreated() like this:

@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);
    view.post(new Runnable() {
        @Override
        public void run() {
            // do operations or methods involved
            // View.getWidth(); or View.getHeight();
            // here
        }
    });
}

run() runs after all views were rendered...
