By measuring the elevation distance—or elevation span—between a country's highest and lowest points, it's possible to average out how flat that country's terrain is. Countries with low topographic relief are considered flatter because there's little variation in elevation. But while some nations have consistently flat terrain, other countries have lower minimum elevations at some points. It's these variables that make this gallery so fascinating. It includes countries you might never have expected to be included in a list such as this!
Sadly, though, some of the lowest-lying nations are particularly susceptible to climate change-induced rising sea levels and coastal erosion. By referencing World Atlas and World Population Review, we've ranked the 30 countries with the lowest average elevations worldwide. Click through and find out how they level up.
Also known as St. Barts, this overseas collectivity of France in the Caribbean has an elevation distance of 286 meters (938 ft) between its highest and lowest points.

Qatar, set on on the northeastern coast of the Arabian Peninsula, has an elevation distance of 103 meters (338 ft) between its highest and lowest points.
Kiribati is an island country in the Micronesia subregion of Oceania in the central Pacific Ocean. It has an elevation distance of 81 meters (266 ft) between its highest and lowest points.
Anchored in the North Atlantic Ocean, remote Bermuda is a British Overseas Territory. It has an elevation distance of 76 meters (249 ft) between its highest and lowest points.
Anguilla is also a British Overseas Territory in the Caribbean. It has an elevation distance of 73 meters (240 ft) between its highest and lowest points.
Niue, a self-governing island country in free association with New Zealand, is situated in the South Pacific Ocean. It has an elevation distance of 68 meters (228 ft) between its highest and lowest points.
Nauru, an island country and microstate in the South Pacific Ocean and the third-smallest country in the world, has an elevation distance of 65 meters (214 ft) between its highest and lowest points.
Gambia is Africa's smallest non-island country. It has an elevation distance of 64 meters (210 ft) between its highest and lowest points.
Set in the Atlantic Ocean, the Bahamas is an island country with an elevation distance of 63 meters (207 ft) between its highest and lowest points.
A British Overseas Territory consisting of the larger Caicos Islands and smaller Turks Islands, the Turks and Caicos Islands, located in the Atlantic Ocean, has an elevation distance of 49 meters (161 ft) between its highest and lowest points.
A British Overseas Territory set in the Caribbean Sea, the Cayman Islands has an elevation distance of 46 meters (151 ft) between its highest and lowest points.
The sovereign state and city-state known as Vatican City has an elevation distance of 42 meters (138 ft) between its highest and lowest points.
The Netherlands is the flattest country in Europe. Over 50% of the country is less than one meter (3.3 ft) above sea level. It has an elevation span of 30 meters (98 ft) between its highest and lowest points.
The Marshall islands, a territory consisting of 29 coral atolls and five main islands located in the northwestern Pacific Ocean, has an elevation distance of 10 meters (33 ft) between its highest and lowest points.
A nation threatened by rising sea levels, Tokelau, a dependent territory of New Zealand in the southern Pacific Ocean, has an elevation span of five meters (16 ft) between its highest and lowest points.
Tuvalu is an island country in the Polynesian subregion of Oceania in the Pacific Ocean. It also has an elevation distance of five meters (16 ft) between its highest and lowest points and is also extremely vulnerable to sea level rise due to climate change.
Likewise, the Maldives, a country and archipelagic state in the Indian Ocean, has an elevation distance of five meters (16 ft) between its highest and lowest points. But because the country’s terrain is consistently 1.5 meters (5 ft) above sea level, the Maldives is actually the flattest country in the world. This makes it among the world's most climate change-vulnerable nations.
