Little Nightmares 3 is a relatively short horror platformer, with most players reporting a main-story playtime of around 5 hours, and closer to 7–8 hours if you go for full completion and collectibles.

Quick Scoop

  • Main story: about 5 hours for an average first run.
  • Rushed second playthrough: roughly 3.5–4 hours if you already know the puzzles and routes.
  • 100% completion: around 7–8 hours when going after all collectibles and trophies.

These numbers put Little Nightmares 3 in the same general range as Little Nightmares 2, which also clocks in at only a few hours for a straightforward playthrough.

Chapter-by-chapter feel

Estimates from early breakdowns and guides suggest that most chapters hover around 45–90 minutes on a normal run, depending on how stuck you get on puzzles or stealth sections.

Replay runs where you already know the solutions shorten several chapters by 10–30 minutes each, especially once enemy patterns and optimal routes become familiar.

Factors that change your playtime

  • Puzzle difficulty: Getting stuck on a puzzle or chase can easily add 30–60 minutes overall.
  • Stealth & deaths: Frequent retries in tense sections will stretch the runtime.
  • Exploration: Players who methodically explore every corner for secrets will naturally push toward the 7–8 hour mark.

How it compares to earlier games

  • Little Nightmares 1: ~3.5 hours main story, up to ~9 hours for completionists.
  • Little Nightmares 2: ~5.5 hours main story, up to ~9 hours for completionists.
  • Little Nightmares 3: about 5 hours main path, ~7–8 hours for 100% at launch, with future DLC chapters expected to extend total playtime further.

So if you’re wondering “how long is Little Nightmares 3” before diving in: think of it as a short, tightly paced horror experience you can finish in a single long evening, or stretch to a weekend if you’re hunting every secret.

TL;DR: How long is Little Nightmares 3? Around 5 hours to beat the story, and roughly 7–8 hours if you aim for all collectibles and trophies, with DLC expected to add more content later.
