It is very common to spot spiders in our home, but they are tiny and don’t even compare to some of the biggest species in the world. 

When we think of “big spiders,” the “Aragog” from the Harry Potter movie immediately comes to mind.

Are you curious about the biggest spider in the world? If yes, keep reading. In this article, we are going to discuss the top 10+ biggest spider species on the earth.
So, let’s begin!

Which Is The Biggest Spider In The World?

The biggest spider in the world is none other than the Goliath Birdeater. The scientific name of this spider is Theraphosa Blondi. In the world of spider species, it is the heavyweight champion.

The leg span of this spider is up to a foot (11 inches), and its weight is around that of a small puppy (6 ounces). It is big enough to cover your dinner plate. Now, you can imagine the size of this giant creature. 

This spider resides in the Amazon rainforest and isn’t typically seen around human habitats. While it is the biggest spider in the world, it doesn’t pose any threat to humans. Instead, it feeds on small insects and vertebrates. 

Which Is The Smallest Spider In The World?

According to Guinness World Records, the smallest spiders come from the Symphytognathidae family. Patu Digua from the Patu genus is the smallest spider in the world.

This spider is so small that it is almost invisible to the naked eye. Their size can be as small as 0.014 millimeters. Unlike the biggest spider in the world, this species resides in the rainforests of Columbia. 

These often go unnoticed by people due to their minuscule size. However, this doesn’t stop them from being great hunters. These spiders mostly prey on smaller creatures like springtails.
