The BFG is described as about 24 feet tall, which is roughly 7.3 meters.

Book version

  • In Roald Dahl’s book The BFG , the Big Friendly Giant is explicitly stated to be 24 feet tall.
  • This makes him huge compared to humans but actually small by giant standards, since the other giants are said to be about twice his height.

Metric conversion

  • Roald Dahl’s official channels have clarified that 24 feet works out to about 731.52 cm , or around 7.3 meters tall.
  • So if you picture a two‑story house, the BFG is roughly that height or a bit taller.

TL;DR: The BFG is about 24 feet tall, which is roughly 7.3 meters.
