Robbie Coltrane, the actor who played Hagrid in the Harry Potter films, was about 6 feet 1 inch tall (roughly 185 cm).

In the movies, Hagrid looks much taller—around 8 feet or more—thanks to a mix of techniques:

  • A very tall body double (rugby player Martin Bayfield, about 6'10") for many wide shots.
  • An animatronic Hagrid head and costume placed on the double’s shoulders to exaggerate the character’s size.
  • Camera tricks, oversized sets, and visual effects to make Hagrid tower over other characters.

So if you’re asking ā€œhow tall is Hagrid actor,ā€ the real-life answer is 6'1", even though the character on screen is portrayed at roughly 8–8½ feet tall.
