# koala vs orangutan

**koala vs orangutan: orangutan leads on 2 of 2 measures**

Measured comparison — not a prediction

A eucalyptus specialist that sleeps up to 20 hours a day because the diet yields so little energy. The largest tree-dwelling animal; adult males develop broad cheek flanges and rarely leave the canopy. On the measurements below, orangutan leads on more of them — but they do not all point the same way, and the ones that disagree are the interesting part.

## The measurements

|  | koala | orangutan |
| --- | --- | --- |
| Mass | 4–15 kg | 30–118 kg |
| Length | 0.6–0.85 m | — |
| Height | — | 1.15–1.5 m |
| Lifespan | 10–20 yr | 35–58 yr |

## Where each one leads

- Mass: orangutan is 7.2× heavier.
- Lifespan: orangutan is 2.7× a longer life.

## What this does and does not tell you

These are measured averages with real ranges behind them, and every figure links to its own page. What they cannot do is settle an encounter. Outcomes between animals turn on circumstance — who initiates, whether either is hungry, defending young, injured or cornered, and what the terrain favours. Size and bite force are not decisive on their own, and most of these pairs never meet in the wild in any case, because their ranges do not overlap.

> Every figure here is an average with a substantial spread. Individual animals vary enormously — a large individual of the smaller species routinely exceeds a small individual of the larger one.

## Common questions

### Is a koala bigger than a orangutan?

orangutan is heavier — 30–118 kg against 4–15 kg.

### Who would win, a koala or a orangutan?

That is not something measurements can settle. The comparison above shows which animal leads on each measure, but an actual encounter depends on circumstance, motivation, health and terrain — and most pairs like this never meet in the wild.
