How big can a monkey grow to?

It depends on the species! Monkeys come in a wide variety of sizes. Here are some examples:

Smallest:

* Pygmy Marmoset: The smallest monkey, reaching only about 5 inches tall and weighing less than 5 ounces.

Medium:

* Capuchin Monkey: Typically around 16-20 inches tall and weighing 3-7 pounds.

* Squirrel Monkey: About 10-16 inches tall and weighing 1-2 pounds.

Largest:

* Mandrill: The largest monkey species, reaching up to 3 feet tall and weighing up to 80 pounds.

* Proboscis Monkey: Known for its large nose, these monkeys can reach up to 3 feet tall and weigh up to 60 pounds.

Other Considerations:

* Sex: Male monkeys are often larger than females.

* Diet and Habitat: A monkey's size can be influenced by its diet and the availability of food in its habitat.

* Individual Variation: Just like humans, there is variation in size among individuals of the same species.

So, there's no one-size-fits-all answer! It's important to be specific about the type of monkey you're asking about to determine its maximum size.
