How big is Dracorex?

A genus of pachycephalosaurid dinosaur from the Late Cretaceous (around 66 million years ago). Its name, Dracorex hogwartsia, translates to "dragon king of Hogwarts," inspired by its dragon-like appearance. Dracorex had a flat skull adorned with spiky horns and knobs. Though debated whether it represents a juvenile form of another species, such as Pachycephalosaurus, it was herbivorous or omnivorous and relatively small, around 10–12 feet (3–4 meters) long.
