# grizzly bear vs Komodo dragon

**grizzly bear vs Komodo dragon: Evenly matched on the numbers**

Measured comparison — not a prediction

The inland North American brown bear, smaller than coastal populations because it eats less salmon. The largest living lizard, which kills large prey with venom and shock rather than jaw power. The measurements below split evenly, which is rarer than it sounds.

## The measurements

|  | grizzly bear | Komodo dragon |
| --- | --- | --- |
| Mass | 130–360 kg | 40–166 kg |
| Length | 1.7–2.4 m | 2–3.13 m |
| Height | 0.9–1.1 m | — |
| Top speed | 56 km/h | — |
| Bite force | 975 psi | 39 psi |
| Lifespan | 20–35 yr | 25–35 yr |

## Where each one leads

- Mass: grizzly bear is 3.9× heavier.
- Length: Komodo dragon is 1.3× longer.
- Bite force: grizzly bear is 25× a stronger bite.
- Lifespan: Komodo dragon is 1.2× 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 Komodo dragon?

grizzly bear is heavier — 130–360 kg against 40–166 kg.

### Who would win, a grizzly bear or a Komodo dragon?

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.
