So for example, a 6 feet tall nerdy-looking geek is better than 5' 6" athlete or celebrity? Doesn't seem logical to me.
The reason why height is so important, is because it serves as a proxy for strength, potential for dominance, and protective capacity. Women feel safe from the world and other men, when they are with a tall man (assuming they also feel safe from him). The circular effect of this is that tall men are seen as a successful archetype from all the attention and resources they get, which inflates their true sexual value. Probably social media and internet has a big hand in this too.
