This map details the countries with an extremely low or high amount of coastline when compared to their areas. Countries in red have an extremely high area-to-coastline ratio, while countries in blue have an extremely low area-to-coastline ratio. Methodology below.

In case it’s hard to read the map, here’s a breakdown of the countries in each category:

Red (High): Congo-Kinshasa, Jordan, Iraq, Bosnia and Herzegovina, Togo, Congo-Brazzaville, Slovenia, Lithuania, Benin, Belgium, Syria, Romania

Blue (Low): Micronesia, Palau, Philippines, Canada, Japan, Norway, Kiribati, Indonesia, Greece, Maldives, Denmark

To generate a list for this map, countries were sorted by taking the square root of their areas and dividing the figure by the country’s coastline length. This ensured that all figures were in linear measure.
