Brazil has borders with every country in South America with the exception of Chile and Ecuador, totalling 16,885 kilometres (10,492 mi). [1] Brazil has the world's third longest land border, behind China and Russia.
The lengths of the borders Brazil shares with different countries, running counter-clockwise around Brazil from French Guiana to Uruguay, are listed below: [1]
Brazil's coastline with the Atlantic Ocean is 7,491 km, which is more than twice the length of its border with Bolivia, the longest land border. [1]
