Supermans number one traits are strength and charisma and if you’re too tall youre going to lack both
Too tall = not enough muscle density because you have so much skin mass, and your body is going to focus its energy into longer limbs instead of brain development meaning you end up much stupider
Same reason scientists are usually 5’5-6 foot - anythiny above 6 foot and you’re generally too dumb for anything except for maybe throwing a ball around
