I'd fit in right next to Ghost Rider, where I belong.
A Visual Size Comparison Of Marvel Characters

This is a visualization comparing the heights of different characters in the Marvel universe, from the diminutive Ant Man to the sun-sized Living Tribunal. A good portion are in the range of normal human heights though, from 1.7 – 1.9m (5’6″ – 6’2″). Me? I’m 6’1″, so I’d fit in right between Captain America and Loki, although I’d ask Captain America to switch places with me so I can stand next to Ghost Rider and use his head to light fireworks.
