Tarantulas are also a type of spider that doesn’t use webs to catch their prey. Instead, they use “the ambush method” with speed, to hunt and chase down their prey. Which brings us to that question, just how fast can a tarantula run exactly?

The average speed of a tarantula is between 8.4 inches per second and 21 inches per second, depending on the tarantula’s size, temperature, and other circumstances such as the surface.

While this many not sound that fast for a tarantulas, its very impressive considering their size.

However, various types of spiders run at different speeds. This means that some tarantulas may be faster or slower than others, depending on their species and age.

You can do this by measuring their speed in inches per second, and converting it into miles per hour by dividing by 17.6.

For example, a tarantula that moves at 8 inches per second would have a speed of approximately 0.45 miles per hour.

If you’re looking to measure and track your tarantula’s movement, this calculation can come in handy. With a little bit of math, you can determine just how quickly your pet spider is scaling their enclosure.

Brazilian Black Tarantula:

These charming spiders belong to a large family called Theraphosidae and are native to rainforest habitats in Brazil and Argentina.

They may be slow compared to other species, with an average speed of 0.3 feet per second, but they make up for this with their impressive jumping ability. Some individuals have been observed leaping distances of up to five feet!

Goliath Bird Eater:

This South American beast is the largest spider on Earth and can grow up to eleven inches in body length. It is surprisingly fast for its size, capable of reaching speeds over three feet per second.

Although not aggressive towards humans unless threatened, this spider should still be handled with caution due to its intimidating size and powerful venomous fangs.

Camel Spider:

Factors That Can Affect The Tarantulas Speed


The size of a tarantula can significantly affect its speed. Smaller tarantulas are generally faster than larger ones.

For example, a small tarantula with a leg span of two inches can move at a speed of 1.5 miles per hour, while a larger tarantula with a leg span of six inches may only move at a speed of 0.5 miles per hour.

It’s important to note that while smaller tarantulas may be faster, they are also more vulnerable to predators.

Larger tarantulas have a better chance of defending themselves against predators, but they are also slower and less agile.


Another factor and what many people may not realize is that temperature can have a huge impact on how fast a tarantula can move.

It’s well-known that tarantulas are ectotherms, meaning they rely on external sources of heat to regulate their body temperature.

This means that the temperature of the environment can play an important role in how fast a tarantula can run or climb.

At lower temperatures (below 18°C/64°F), tarantulas typically move very slowly, as their muscles and nerves become sluggish due to the cold.

At higher temperatures (above 24°C/76°F), however, tarantulas tend to be more active and can move faster.
