Paper typically ignites at around 450–480°F (about 230–250°C), but the exact temperature depends on the type and thickness of the paper.

Quick Scoop

  • A commonly quoted value is 451°F (233°C) as the ignition point of “book paper,” popularized by Ray Bradbury’s Fahrenheit 451 and also cited in physics references.
  • More recent tests suggest many papers auto‑ignite closer to around 480°F (≈249°C) in controlled conditions.
  • Different papers burn at different temps:
    • Thin newspaper can start burning around 180°C (356°F).
* Thicker or denser papers may require up to **300°C (572°F)** to ignite.
  • Once burning, the center of a paper fire can reach about 1,500°F (815°C) , with flame tips around 600–800°F (315–427°C).

So if you’re asking “what temp does paper burn,” the short, practical answer most people use is: about 450–480°F (≈230–250°C), with 451°F a famous shorthand for book paper.

Safety note

These numbers come from lab-style or idealized conditions; in real life, open flames, airflow, and how the paper is stacked can make it catch fire at somewhat lower or higher temperatures. Always treat high heat and open flames cautiously around any kind of paper.
