20 Largest Deserts in the World
Last Updated on Apr 29, 2022
Vast spaces of barrenness with no trees, harsh landscapes, and difficult living conditions. That’s what deserts are! But did you know that deserts aren’t just hot and arid but can be cold and freezing too.
What makes a desert a desert is a fact that the place receives less than 10 inches or 25 cms of rain per year. So you can have hot sandy deserts, polar deserts, or even subtropical deserts.
Covering over one-fifth of the earth’s landmass, deserts are far from lifeless. They are filled with unique plants, animals, organisms, and human communities that have adapted to desert life for centuries. So of visiting a desert is now on your radar, here are the 20 largest deserts in the world!
1. Antarctic Desert
A blanket of frozen ice as far as the eye can see – it’s difficult to think of Antarctica as a dessert. But that’s what it is! The largest desert on this planet covering 5,500,000 square miles or 14,200,000 square kilometers.
Receiving only 8 inches or 20 cm of rain a year, the average temperature in the coldest part of the year is −63 °C (−81 °F), but it has gone down as far as -94.7C (-135.8F) in Aug 2010.
Home to over 90% of the world’s ice, there’s actually plenty to do in the Antarctic – from visiting popular outposts to catching a glimpse of Penguins or wandering Albatross and other unique wildlife.
2. Arctic Desert
The only other polar desert in the world, the Arctic tundra has long winters and short summers. Covering an area of 5,300,000 square miles or 13,900,000 square kilometers, the average precipitation is between 150-250mm or less than 8 inches.
Temperatures in most regions are below 0°C (32°F), although researchers differ on which parts are desert, the commonly agreed areas are the North Pole, the Arctic Basin, and the Canadian Arctic Archipelago.
3. Sahara Desert
Often thought of as the world’s largest desert, the Sahara is actually the third largest. Covering an area of 3,600,000 square miles or 9,200,000 square kilometers, the Sahara desert has an average precipitation of lesser than 8 inches or 250 mm of rainfall.
This land of sand dunes and rocky plateaus covers almost 31% of the African continent. But it is also home to beautiful Air Mountains, Ahaggar Mountains, Saharan Atlas, Red Sea Hills, and more.
Because of its diversity, the Sahara is home to a variety of wildlife – from camels and foxes to antelopes and cheetahs.
You’ll also find that many civilizations past and present developed their architecture to adapt to the inhospitable conditions the earth provided to them.
4. Arabian Desert
Covering 2,330,000 square km or 899,618 square miles, the Arabian desert covers most of the Arabian Peninsula, stretching from the Persian Gulf to Yemen.

Home to arachnids and oil fields, books have been written about the Empty Quarter.
While the Arabian desert is difficult to live in, it hasn’t stopped cities from being built here. Did you know that Riyadh is in the center of this desert?
5. Gobi Desert
The vastness of this desert in Mongolia and China is bounded by the steppes and Altai Mountains in the North and the Hexi Corridor and Tibetan Plateau in the South.
Had it not been for the Tibetan Plateau blocking precipitation, the Gobi area would not have been classified as a desert.
Home to the famous Silk Route cities of Karakorum and Khanbaliq, it’s also been written about in The Travels of Marco Polo.

Many of the mountain ranges within the desert have created ‘sky islands’ with forest woodlands. There are many urban cities in the desert too – Albuquerque, Saltillo, Fort Stockton, Fort Sumner, Roswell, Torreon, and more.
According to the World Wide Fund for Nature, because of the variety of species, the Chihuahuan Desert may be the most biologically diverse desert in the world.
11. Karakum Desert
The Karakum or Garagum desert covers over 70% of Turkmenistan in Central Asia. (It’s different from the Aral Karakum in Kazakhstan which is a smaller desert.)
