In not 100% sure but I remember that the size is 0 until the component is rendered. In this moment the browser calculates the layout of the page.
And the browser executes first the js code, then update the DOM and finally it repaint the page. In this case, the final width and height are not available in the constructor. You can try using a resize event. I think it's called when the browser sets the initial values.
