The longest borders

Canada and United States share 8,891 km, including the border between Alaska and Canada. Next come Kazakhstan–Russia (7,644 km), Argentina–Chile (6,691 km), China–Mongolia (4,630 km) and Bangladesh–India (4,142 km).

How border lengths are measured

Border lengths follow the CIA World Factbook. Natural borders along rivers and mountain ridges are long and winding, so published figures differ between sources — treat them as close approximations.
