How Long is the Amazon River?

How long is the Amazon River? It seems like a simple question, but the truth is that this has been plaguing scientists, explorers, and the geographical society for decades. How hard can it be to measure a river? The answer to that is actually pretty hard because there are a number of factors to take into account and everyone has a different idea of how to measure the river.


The Amazon River is 4,225 miles long, or 6,800 km in length.


By volume, the Amazon River is the largest river in the world – this much we know for sure. Its basin is home to the magnificent Amazon Rainforest and its banks provide a home for millions of people and animals across the continent of South America. The river itself is the lifeblood of the nations through which it runs, acting as a source of water, a habitat, and a transportation route.


Amazon River Length

When determining the length of a river, it is important to know where it begins and ends. This much seems obvious but it is exactly where the confusion stems from. For a long time, Carhuasanta Creek in southern Peru was one of the widely accepted starting points for the river. However, in 2007, a group of Brazilian scientists put forward a theory that the Apacheta Creek is actually the source of the Amazon River.


As for the mouth of the river, scientists all agree that the river dumps out into the Atlantic Ocean, but there are three outlets from which it does this. Two are on the northern side of Brazil’s Marajo Island and one is on the southern side. This latter outlet joins with the Pará River before churning out into the Atlantic Ocean.

You might wonder why it matters where the exact beginning and end point of the river is. Well, when it comes to determining length, these details make all the difference and can be the deciding factor between whether or not the Amazon River is the longest river in the world or whether that crown goes to the Nile River. Most recent estimates states that the Amazon River is 4,225 miles long, while the Nile is 4,160 miles in length. This means that the Amazon River is the longest river in the world – for now.
