Rubeus Hagrid is described differently in the Harry Potter books and films in terms of height. In the books, Hagrid is said to be a half-giant and is approximately 11 and a half feet tall (about 3.5 meters), which is roughly twice the height of an average man.
In the film adaptations, Hagrid's height is portrayed as about 8 feet 6 inches tall (2.59 meters), which is smaller than the book description but still significantly taller than an average person. This height was achieved through several practical effects, forced perspective, and camera tricks since the actor Robbie Coltrane who played Hagrid was only 6 feet 1 inch tall.
