The BFG is described as being about 24 feet tall in Roald Dahl’s story, which is roughly 7.3 meters.

Height in the book

  • In the original Roald Dahl novel The BFG , the Big Friendly Giant is explicitly characterized as a 24-foot -tall giant, making him small compared with the other giants in Giant Country.
  • The man‑eating (or human‑eating) giants in the same story are usually around 50 feet tall, so they tower over the BFG and bully him for being the “runty” one.

Height in other sources

  • A Roald Dahl estate social post notes that the BFG was 24 feet tall, converting this to about 731.52 cm for metric readers.
  • Character reference guides and study resources for the book also repeat that the BFG is 24 feet tall and contrast this with larger giants like the 54‑foot Fleshlumpeater.

TL;DR: When people ask “how tall was the BFG,” the widely accepted answer, from the book and official character references, is that he was about 24 feet (around 7.3 meters) tall.
