# black mamba vs cheetah

**black mamba vs cheetah: Evenly matched on the numbers**

Measured comparison — not a prediction

The fastest snake and Africa's longest venomous one; it is named for the black inside of its mouth, not its colour. The fastest land animal, with a lightweight frame and semi-retractable claws for traction. The measurements below split evenly, which is rarer than it sounds.

## The measurements

|  | black mamba | cheetah |
| --- | --- | --- |
| Mass | 1–3.1 kg | 34–72 kg |
| Length | 2–4.3 m | 1.1–1.5 m |
| Height | — | 0.7–0.9 m |
| Top speed | 11–20 km/h | 93–104 km/h |
| Lifespan | 10–20 yr | 8–17 yr |

## Where each one leads

- Mass: cheetah is 31× heavier.
- Length: black mamba is 1.9× longer.
- Top speed: cheetah is 6.3× faster.
- Lifespan: black mamba is 1.1× 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 black mamba bigger than a cheetah?

cheetah is heavier — 34–72 kg against 1–3.1 kg.

### Who would win, a black mamba or a cheetah?

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.
