Kv file outputs different results from calling it into native python

I print in the build function of the app root.size and get the ouptut (100,100) which is default to any widget, but if I try to create a button in the .kv file that when is pressed prints root.size prints (800,600) Why is that happening?

class MovieApp(App):
    def build(self):
        root = MovieScreen()
        print(root.size)
        return MovieScreen()
MovieApp().run()

movie.kv

<MovieScreen>
    Button:
        on_press: print(root.size)
        pos_hint: {"x": 0, "y": 0}
        background_color: 1,0,0,1

Because during the build method root.size has value (100, 100), but once the app is running root.size has value (800, 600), presumably because the layout logic has now run and it is filling the default-sized Window.
