Understanding the Impressive Size of Banana Spiders

With their large, furry bodies and long leg spans, banana spiders are definitely one of the most eye-catching arachnids out there. While not truly a banana spider, the Giant Golden Orb Weaver is often referred to by this common name due to its similar coloration.

But just how big do these giant banana spiders get? Let's take a closer look at the size and growth of these enormous web weavers!

What Kind of Spider is the Banana Spider?

There are a few spiders that are commonly called banana spiders, including:

• Golden Silk Orbweavers
• Brazilian Wandering Spiders
• Spiny Orbweavers

When most people refer to a banana spider, they are talking about the Giant Golden Orb Weaver (Nephila clavipes). This spider builds large, impressive webs and grows to an impressive size.

How Big Do Banana Spiders Get?

The Giant Golden Orb Weaver is considered a banana spider size queen in the spider world, growing to about 5 inches (12 cm) in legspan. That's over the size of your palm!

Females reach even more epic proportions at up to 5.9 inches (15 cm) in legspan. They can be over 1.5 inches (4 cm) in body length as adults.

Banana Spider Leg Span Vs. Body Size

A banana spider's size is defined more by its leg span than body mass. Their legs make up the majority of their impressive size spread.

The female banana spider has a noticeably larger body than the male. Females can have a body size around 0.6 inches (15 mm) in length, while males are closer to 0.4 inches (10 mm).

How Fast Do Banana Spiders Grow?

Baby banana spiders, called spiderlings, are tiny when they first hatch. But they grow quickly into their giant webbed orb habitats.

Here's a look at how fast these spiders grow:

• Spiderlings begin around just 1 to 2 mm
• Within their first year they reach 1 inch (2.5 cm) in size
• In two years they achieve full adult legspan and body size

Their fast growth allows them to start spinning impressive webs and reproducing within a short lifecycle of just a couple years.

Giant Golden Orb Weaver Facts & Traits
