Hi Jeff, the magnification or size of an object only depends on the focal length of the telescope and the focal length of the eyepiece.
A bigger objective diameter can give greater resolution, brightness and contrast, even though the planet is the same size; a wider afov eyepiece will show more black space around the same sized planet.
