Comparison to Western Concepts: In English, we might say something is a “good fit” or “commensurate with.” However, “a good fit” can be highly subjective (“I think this modern art fits in this classic room because I like it”). 相称 implies a more objective, almost measurable, standard of appropriateness. It's less about personal taste and more about whether something logically, ethically, or aesthetically corresponds to something else. For example, a severe punishment for a minor crime is seen as objectively out of proportion, or 不相称. This reflects a societal value on propriety and ensuring that actions, status, rewards, and appearances are all aligned correctly.
