how long is dune

Dune is a long story in every form, so the answer depends on which Dune you mean.

Quick Scoop

Movie runtimes

• Dune (2021, Denis Villeneuve – “Part One”): about 155 minutes, roughly 2 hours 35 minutes.

• Dune: Part Two (2024, Villeneuve): about 165 minutes 37 seconds, roughly 2 hours 45 minutes.

• A double‑feature of Part One + Part Two is just over 5 hours total.

Older movie

• Dune (1984, David Lynch): about 137 minutes (around 2 hours 17 minutes), so shorter than the 2021 film.

Book length (for context)

Frank Herbert’s original novel Dune is famously hefty in print (often 600–800 pages depending on edition), which is why the modern adaptation was split into at least two long movies, each well over 2 hours.

Think of it this way: if you sit down for a full modern Dune movie night, you’re signing up for an epic, roughly five‑hour desert journey — spice, sandworms, and all.

TL;DR:

• “How long is Dune (2021)?” → ~2h 35m.
• “How long is Dune: Part Two?” → ~2h 45m.
• “Both together?” → just over 5 hours of Arrakis.
