The largest deserts in the world are not all hot and sandy — a fact that surprises most students and trips up many in exams.
Desert geography is a recurring topic in UPSC Prelims, SSC CGL, Banking, Railways, and State PSC papers. This page gives you a complete, updated list of the world’s biggest deserts with their area, type, location, and exam-focused facts — with an interactive table, desert comparison tool, and progress tracker.
⚡ Quick Facts
- Antarctica is the world’s largest desert at 14.2 million sq. km — cold polar, not hot.
- The Sahara is the world’s largest hot desert — ~9.2 million sq. km across 11 countries.
- The Arabian Desert is the largest desert in Asia (2.3 million sq. km).
- The Thar Desert is shared by India and Pakistan — world’s most densely populated desert.
- Deserts cover approximately one-third of Earth’s total land surface.
Many students write “Sahara” as the world’s largest desert. The correct answer is the Antarctic Desert. Always distinguish between “largest desert” (Antarctic) and “largest hot desert” (Sahara).

⚖️ Compare Two Deserts
📝 Key Notes & Memory Tips
The Antarctic Desert (14.2 million sq. km) is the LARGEST desert in the world. A desert is defined by low precipitation (under 250 mm/year), not by heat. This is the most commonly tested fact in this topic.
The Sahara is the largest HOT desert — exam questions specifically ask for “largest hot desert” to catch students who write Sahara for the overall largest. It spans 11 countries in North Africa.
The Gobi Desert (China/Mongolia) is a cold temperate desert. Temperature swings from −40°C in winter to +45°C in summer. Students often assume all Asian deserts are hot.
The Thar Desert = “Great Indian Desert”. World’s most densely populated desert. Located in Rajasthan (India) and Pakistan’s Sindh and Punjab.
The Atacama Desert in Chile is the driest non-polar desert on Earth. Some stations have never recorded rainfall. Kept dry by the cold Humboldt Current.

The Antarctic Desert (14.2 million sq. km) is the largest desert. Deserts are defined by low precipitation, not heat — Antarctica receives less than 200 mm/year.
The Sahara Desert (~9.2 million sq. km, 11 countries in North Africa) is the world’s largest hot desert — 3rd overall after Antarctic and Arctic.
The Thar Desert (Rajasthan, India + Pakistan) is also called the Great Indian Desert. It is the world’s most densely populated desert (~200,000 sq. km).
Atacama Desert is in northern Chile and Peru (South America). It is the driest non-polar desert, kept arid by the cold Humboldt Current and Andes rain-shadow.
The Gobi Desert (China/Mongolia) is a cold temperate desert with temperatures from −40°C to +45°C. Sahara, Arabian, and Thar are hot deserts.

❓ Frequently Asked Questions
The Antarctic Desert (14.2 million sq. km) is the largest. A desert is defined by low precipitation (under 250 mm/year), not heat. Antarctica receives virtually no precipitation annually.
Four types: hot deserts (Sahara, Arabian, Thar), cold polar deserts (Antarctic, Arctic), cold temperate deserts (Gobi, Patagonian, Great Basin), and cold coastal deserts (Atacama, Namib).
The Thar Desert in Rajasthan — ~200,000 sq. km — is the largest in India. It extends into Pakistan’s Sindh and Punjab. It is the world’s most densely populated desert, home to cities like Jodhpur and Jaisalmer.
Deserts feature regularly in UPSC, SSC CGL, Banking GA, and Railways. Key tested points: largest/hottest/driest deserts, correct type classification, Thar Desert location in India, and the Antarctic vs Sahara distinction. The cold desert trap is a favourite examiner trick.
