# polar bear vs white rhinoceros

**polar bear vs white rhinoceros: white rhinoceros leads on 5 of 5 measures**

Measured comparison — not a prediction

The largest living land carnivore, classified as a marine mammal because it hunts from sea ice. The largest rhino and the second-largest land mammal, a grazer with a wide square lip. On the measurements below, white rhinoceros 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

|  | polar bear | white rhinoceros |
| --- | --- | --- |
| Mass | 150–700 kg | 1,400–3,600 kg |
| Length | 1.8–3 m | 3.4–4.2 m |
| Height | 1–1.6 m | 1.5–1.9 m |
| Top speed | 40 km/h | 50 km/h |
| Bite force | 1,200 psi | — |
| Lifespan | 20–32 yr | 35–50 yr |

## Where each one leads

- Mass: white rhinoceros is 4.4× heavier.
- Length: white rhinoceros is 1.6× longer.
- Height: white rhinoceros is 1.4× taller.
- Top speed: white rhinoceros is 1.3× faster.
- Lifespan: white rhinoceros is 1.8× 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 polar bear bigger than a white rhinoceros?

white rhinoceros is heavier — 1,400–3,600 kg against 150–700 kg.

### Who would win, a polar bear or a white rhinoceros?

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.
