The size will be 0,0 until it is displayed because the components and layout are not calculated beforehand.

thePanel.getSize();

This returns the Dimension.

I sometimes add a ComponentListener to show the dimension when the panel is resized.

EDIT: If you want the size of the content pane of the JFrame then

theFrame.getContentPane().getSize();
