The principle of relative size states that when two objects are the same size, the one that appears larger is perceived as being closer. This is because as objects move farther away, they appear smaller. So when two objects are the same actual size, the one that appears larger must be closer. This is a monocular cue and does not involve any binocular depth cues like retinal disparity.
