# hippopotamus vs white-tailed deer

**hippopotamus vs white-tailed deer: hippopotamus leads on 4 of 5 measures**

Measured comparison — not a prediction

A semi-aquatic grazer, the third-heaviest land mammal and among the most dangerous to people. The most abundant large mammal in North America, with about 30 million animals. On the measurements below, hippopotamus 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

|  | hippopotamus | white-tailed deer |
| --- | --- | --- |
| Mass | 1,300–3,200 kg | 25–150 kg |
| Length | 3.3–5 m | 1.5–2.1 m |
| Height | 1.3–1.65 m | 0.8–1.1 m |
| Top speed | 25–30 km/h | 48 km/h |
| Bite force | 1,800 psi | — |
| Lifespan | 40–55 yr | 3–20 yr |

## Where each one leads

- Mass: hippopotamus is 21× heavier.
- Length: hippopotamus is 1.9× longer.
- Height: hippopotamus is 1.5× taller.
- Top speed: white-tailed deer is 1.6× faster.
- Lifespan: hippopotamus is 7.5× 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 hippopotamus bigger than a white-tailed deer?

hippopotamus is heavier — 1,300–3,200 kg against 25–150 kg.

### Who would win, a hippopotamus or a white-tailed deer?

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.
