Each subclass of node can determine the minimum width it requires. This can be overridden on an ad-hoc basis using overrideMinHeight. The default implementation returns 0.

Each subclass of node can determine its preferred height. As most nodes are composed of smaller nodes, this is typically calculated using evalPrefWidth of the child nodes, with extra added for spacing, padding and borders.
