Tigers are very large cats: most adults are roughly 2.5–3.3 meters long from nose to tail and usually weigh about 100–300 kilograms, with some big males even heavier.

Basic size range

  • An adult tiger’s body length (head to base of tail) is about 1.5–3.0 meters, with the tail adding roughly another 0.6–1.0 meters.
  • Adult males across subspecies commonly weigh about 180–300 kilograms, while females are lighter, often around 100–180 kilograms.

Biggest and smallest tigers

  • The largest subspecies, the Siberian (Amur) tiger, can reach around 441–701 pounds (about 200–318 kilograms) for big males, making them among the heaviest cats on Earth.
  • Smaller subspecies like the Sumatran tiger have males more in the 220–310 pound (100–140 kilogram) range, with females lighter still.

Simple size comparison

  • A big male tiger can be about as long as a small car and weigh as much as three to four adult humans.
  • Even “small” adult tigers are still larger and heavier than almost any big dog breed.
