public class PlasticComboBoxUI extends MetalComboBoxUI
The JGoodies Plastic Look and Feel implementation of ComboBoxUI. Has the same height as text fields - unless you change the renderer.

Also, this class offers to use the combo's popup prototype display value to compute the popup menu width. This is an optional feature of the JGoodies Plastic L&fs implemented via a client property key.
