Find your animal-kingdom weight twin
The animal kingdom contains creatures of almost every weight imaginable, from 2-milligram fairyflies to 200-tonne blue whales. Somewhere in that spectrum lies an animal whose body weight is the closest match to yours. Find your "weight twin" — the creature you\'d match perfectly on a kitchen scale — and see how far you are from the next animal up or down the size ladder.
Frequently asked questions
How is my animal weight twin chosen?
We compare your weight against typical adult weights of representative animal species across the animal kingdom — pets, livestock, wild mammals, large birds, reptiles and a few notable invertebrates. The closest match (smallest absolute weight difference) is your animal twin.
What's the biggest animal on Earth?
The blue whale (Balaenoptera musculus) is the largest animal ever known to have existed — up to 200 tonnes and 30 metres long. A single blue whale weighs more than 2,500 average adult humans.
How many animal species are there?
Around 8.7 million species have been estimated by scientists, of which about 1.5 million have been formally described. Mammals make up just 0.07% — there are far more insects than vertebrates.
One of the more astonishing things about the animal kingdom is its weight range — about 14 orders of magnitude from smallest to largest. Where you fall in that range probably puts you somewhere in the company of mid-sized mammals: pigs, sheep, deer, wolves. Larger humans approach lion or panther territory; smaller humans share weight space with golden retrievers and sheep.

Mammals dominate the human weight range
Adults typically fall between 45 and 120 kg, which puts the human weight range squarely in the territory of large mammals: big cats, ungulates, large dogs, primates. There are very few birds or reptiles in this range — the largest flightless birds (ostrich, cassowary) reach 100 kg or so, and the heaviest reptiles (saltwater crocodile) get to 1,000+ kg, leaping past most humans.
