List of countries and territories by number of land borders



This list gives the number of distinct land borders of each country or territory, as well as the neighboring countries and territories. The length of each border is included, as is the total length of each country's or territory's borders.

Countries or territories that are connected only by man-made structures such as bridges, causeways or tunnels are not considered to have land borders. However, borders along lakes, rivers, and other internal waters are considered land borders for the purposes of this article.

Coastline paradox
Due to the coastline paradox, it is not always possible to determine border lengths, especially where borders are marked by rivers and coastlines, as the resulting measurements are highly dependent on the resolution at which the borders are recorded. For instance, the more accurately you measure the nooks and crannies of a given beach, the longer the border will inevitably become.

Artificial border crossings
In addition to the above number of land borders per country, some countries have a man-made bridge, causeway or tunnel between each other without having any proper land border. These artificial land borders are usually less than 50 m long.
