A kiwi bird is about the size of a chicken: roughly 35–45 cm (14–18 in) long for the smaller species and up to about 50–65 cm (20–25 in) for the largest, weighing between about 0.8 and 5 kg (1.8–11 lb) depending on species and sex.

Quick Scoop: How big is a kiwi bird?

  • Most kiwis are about chicken-sized, with a round body and short legs.
  • Smallest species (little spotted kiwi): about 35–45 cm long and roughly 0.8–1.9 kg.
  • Larger species (great spotted and brown kiwi): around 45–65 cm tall and up to about 3–5 kg for big females.
  • They stand roughly 25–60 cm (10–24 in) tall, so much bigger than the fruit and similar in height to a barnyard chicken.
