Music for the articleHuge Man and a Tiny WomanSome writers like pairing up characters of opposite sex and opposite ends of the size spectrum. The height difference goes well beyond One Head Taller, and the tall one is often several times wider to boot.
Averted more often than not in film and Live-Action TV, where props and camera angles are employed to equalize the heights of the leading man and lady, to make filming easier (otherwise, getting them in the same shot would be a pain in the arse). Even when the actors themselves represent this trope, if it appears on screen you can be sure there was an intentional choice to invoke it.
Usually, it's the man who's bigger. This is an exaggeration with some basis in truth: the median height for males is slightly higher than that for females, and many men and women choose opposite-gender mates with the "traditional" comparative height. Physical attraction aside, the idea of a big hulking giant showing his soft side for his little lady is popular with female viewers.
Tiny Man and A Huge WomanMen are usually bigger/taller than women, right? Well, most of the time, but there are cases in which a woman will be taller than her love interest, either because she's unusually tall or because he's unusually short. Sometimes it's both. However this does not make the Woman unattractive.
This is true in real life for most arthropods, reptiles, and birds. However, for mammals, it's reversed. This however can happen in real life with a man and a woman but is much rarer.
When this happens, the man might feel self-conscious about dating a woman larger than him, or the girl might feel similarly insecure about dating a man much shorter/smaller than her. But in other cases, the guy will find a woman attractive not "despite" how tall she is, but partly because of it.
In rare cases the Woman might be big enough to hold the Man in her palm or shirt pocket.
In other cases the Woman might be 6,3 or the Man might have a Napoleon Complex.
In rarer cases the Woman Might have a wider body than the Man
