# grizzly bear vs red kangaroo

**grizzly bear vs red kangaroo: grizzly bear leads on 3 of 5 measures**

Measured comparison — not a prediction

The inland North American brown bear, smaller than coastal populations because it eats less salmon. The largest marsupial; a hopping gait that gets more efficient the faster it goes. On the measurements below, grizzly bear 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

|  | grizzly bear | red kangaroo |
| --- | --- | --- |
| Mass | 130–360 kg | 18–92 kg |
| Length | 1.7–2.4 m | 0.85–1.6 m |
| Height | 0.9–1.1 m | 1–1.8 m |
| Top speed | 56 km/h | 56 km/h |
| Bite force | 975 psi | — |
| Lifespan | 20–35 yr | 12–25 yr |

## Where each one leads

- Mass: grizzly bear is 4.5× heavier.
- Length: grizzly bear is 1.4× longer.
- Height: red kangaroo is 1.5× taller.
- Top speed: near enough identical.
- Lifespan: grizzly bear is 1.3× 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 grizzly bear bigger than a red kangaroo?

grizzly bear is heavier — 130–360 kg against 18–92 kg.

### Who would win, a grizzly bear or a red kangaroo?

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.
