[Eritrea](https://www.britannica.com/place/Eritrea) is an East African country in the Horn of Africa. The coast of Eritrea lies along the Red Sea, while Djibouti, Sudan, and Ethiopia surround the country's other borders. The GPS coordinates of Eritrea are a latitude of 15.1794° N and a longitude of 39.7823° E.
In the north, Eritrea reaches an extremity of 18°00' N. As part of the cape of Ras Kasar, the northernmost point of the country falls on the water border between Sudan and Eritrea. The body of water that Ras Kasar lies along is the Red Sea.
The southernmost point of Eritrea is along the border that separates Djibouti and Eritrea. More specifically, it falls in the Southern Denkalya Subregion of Africa. With a latitude of 12°22' N, this point is southwest of the African country of Djibouti.
In the east, Eritrea extends as far as a longitude of 43°7' E. Similar to the southernmost point of the country, the easternmost point is also part of the Djibouti-Eritrea border, though it is part of a different subregion. Eritrea’s easternmost point is considered part of the Southern Red Sea Region of the country.
The westernmost point of extremity in Eritrea has a longitude of 36°50' E. Positioned in the region of Gash-Barka, Eritrea’s furthest point to the west is along the border between Eritrea and Sudan. This point lies to the west of Teseney, which is a small town near the Gash River.
The total area of the country is approximately 45,405 square miles. About 38,996 square miles of Eritrea’s total area is made up of land regions, while the other 6,409 square miles are land areas, like rivers, lakes, reservoirs, and other forms, making Eritrea roughly 86% land and 14% water. From a measurement standpoint, Eritrea’s total area is about 186.05 miles wide and 138.46 miles long.
Eritrea‘s population size as of 2019 is about 5,253,277 people. While populations are very prone to fluctuation, the current population is equal to a mere 0.07% of the world’s total population. With this in mind, it makes sense that Eritrea is 120th most populous country in the world, out of a total of 196 countries by comparison.
