Dune’s Giant Sandworm, Explained Ahead Of The Denis Villeneuve Movie

Larger sandworms likely exist, though. In the book, when Paul Atreides summoned a sandworm, it’s said the worm that came out of the desert sand “appeared to be around a half a league long and the rise of the sandwave at its cresting head was like the approach of a mountain.” A half a league is roughly 2,778 meters (or 9,121 ft) which is, of course, massive. On another occasion, when Paul met a sandworm for the first time, it was said, “Its mouth was some eighty meters in diameter…” All of this is to say that sandworms are huge on the desert planet of Arrakis.
