Situated on the northeast coast of South America, Guyana is the third-smallest country on the continent, with an area of 214,970 sq km (83,000 sq mi), extending 807 km (501 mi) N – S and 436 km (271 mi) E – W , including disputed areas. Comparatively, the area occupied by Guyana is slightly smaller than the state of Idaho. Bounded on the N by the Atlantic Ocean, on the E by Suriname, on the S and S-W by Brazil, and on the NW by Venezuela, Guyana has a total boundary length of 2,921 km (1,815 mi) of which 459 km (285 mi) is coastline.
Neither Guyana's western border with Venezuela nor its eastern border with Suriname has been resolved. Venezuela claims all territory west of the Essequibo River, an area of more than 130,000 sq km (50,000 sq mi), or over three-fifths of Guyana. Suriname claims a largely uninhabited area of 15,000 sq km (5,800 sq mi) in the southeast, between two tributaries of the Corentyne River.
Guyana's capital city, Georgetown, is located on the country's Atlantic coast.
