Length of Coastlines by Country and World

This bar chart show the approximated length of coastlines by country (top 100) and the world, in kilometers and miles, derived from World Vector Shoreline database at 1:250,000 scale.Show more

The methodology used to estimate length is based on the following: 1) A country's coastline is made up of individual lines, and an individual line has two or more vertices and/or nodes. 2) The length between two vertices is calculated on the surface of a sphere. 3) The sum of the lengths of the pairs of vertices is aggregated for each individual line, and 4) the sum of the lengths of individual lines was aggregated for a country. In general, the coastline length of islands that are part of a country, but are not overseas territories, are included in the coastline estimate for that country (i.e., Canary Islands are included in Spain). Disputed areas are not included in country or regional totals.

Caspian Sea is included as part of coastlines, thus countries like Uzbekistan and Kazakhstan are not considered landlocked.
Macau and Hong Kong are included in China, but not Taiwan.
The world counter includes all coastlines.
