how big can bats get

Bats can get surprisingly huge—some are about as wide as a tall adult person when their wings are fully spread.

The Biggest Bats on Earth

When people ask “how big can bats get,” they’re really asking about the flying foxes , a group of large fruit bats.

The giant golden-crowned flying fox (Acerodon jubatus) from the Philippines is often cited as the largest bat in the world by wingspan.

Typical figures for the largest flying foxes are:
- Wingspan: about 1.6–1.7 m (around 5–5.6 ft).

* Weight: up to about **1.4–1.6 kg** (roughly **3–3.5 lb**).

In other words, the very largest bats have a wingspan similar to a person’s arm span, but they’re much lighter than even a small child.

Here’s a simple size snapshot of some of the biggest bats:

How That Compares to “Normal” Bats

Most bats are much smaller than the headline-grabbing giants.

Many common microbats have wingspans of just a few dozen centimeters and weigh under 50 g.

One of the tiniest, Kitti’s hog-nosed bat , is only about 29–33 mm long and 2 g in mass.

So the range goes from something barely larger than a bumblebee to something with a wingspan like a tall human’s arm span.

Could Bats Get Even Bigger?

Biologists often talk about limits on flying animals , and bats are no exception.

Bigger wings need more muscle power and very efficient breathing; past a point, a bat’s body would be too heavy for its wings.

There’s no solid evidence of any naturally occurring bat much larger than the biggest flying foxes listed above, despite occasional “giant bat” stories online and in forums.

So today’s record-holding bats are probably close to the practical upper limit for real, living bat species.

A Little Story-Style Picture

Imagine standing in the dusk near a forest edge in the Philippines: a dark shape glides overhead, silent except for a faint rustle. You look up and see a bat whose wings reach from one side of a doorway to the other, but when it lands in a tree it just hangs there like a skinny, cloaked fox, no heavier than a large bottle of water.

That’s about as big as bats get. 🦇 TL;DR:
The largest bats, like the giant golden-crowned flying fox, can reach about 1.6–1.7 m (around 5–5.6 ft) in wingspan and around 1.4–1.6 kg (about 3–3.5 lb) in weight —roughly the width of an adult person’s outstretched arms, but far lighter.
