Key facts

  • Rajasthan's coordinates, area and border ring explain why desert, hills, plains and plateau coexist in one state.
  • The Aravalli axis is the master divider: western Marusthali lies on one side, alluvial and plateau belts on the other.
  • Border geography is directional and regional: Punjab-Haryana in the north, Uttar Pradesh-Madhya Pradesh in the east and south-east, Gujarat and Pakist…
  • Western Rajasthan is sandy and internally drained, with Luni-Ghaggar patterns and canal-modified command areas.
  • Eastern Rajasthan is river-linked: Banas and Chambal shape the alluvial plain, Hadoti and the ravine belt.

Key Points at a Glance

  1. 1

    Rajasthan's coordinates, area and border ring explain why desert, hills, plains and plateau coexist in one state.

  2. 2

    The Aravalli axis is the master divider: western Marusthali lies on one side, alluvial and plateau belts on the other.

  3. 3

    Border geography is directional and regional: Punjab-Haryana in the north, Uttar Pradesh-Madhya Pradesh in the east and south-east, Gujarat and Pakistan in the west and south-west.

  4. 4

    Western Rajasthan is sandy and internally drained, with Luni-Ghaggar patterns and canal-modified command areas.

  5. 5

    Eastern Rajasthan is river-linked: Banas and Chambal shape the alluvial plain, Hadoti and the ravine belt.

  6. 6

    Map questions become easier when each region is tied to districts, relief, drainage and one exact number.

Where is Rajasthan located, and how large is it?

Rajasthan lies in north-western India between about 23°03' N to 30°12' N latitude and 69°29' E to 78°17' E longitude, and it is India's largest state by area at 342,239 sq km. Rajasthan occupies the north-western corner of India, but its internal map is not a simple desert block. According to the Rajasthan Department of Mines & Geology, the state's official location is between latitude 23°03' to 30°12' N and longitude 69°29' to 78°17' E.

Extent and Span

Measure Detail
Rajasthan Latitudinal-Longitudinal Extent The state is fixed between roughly 23°03' to 30°12' north latitude and 69°29' to 78°17' east longitude in official state material.
Rounded western longitude Many Rajasthan geography tables round the western longitude to 69°30'E.
South-north reach From the Banswara belt to Ganganagar.
West-east reach From the Jaisalmer desert fringe to Dholpur on the Chambal side.
North-south span About 826 km.
East-west span About 869 km.
  • Because of this span, climate changes across both latitude and relief.
  • Tropic of Cancer near Banswara adds a southern tropical edge.
  • Northern districts face stronger continental and arid influence.

Area Anchor

Fact Detail
Total Area of Rajasthan (Largest Indian State) 342,239 sq km.
Share of India About 10.41 percent of India's geographical area.
Status since 2000 Since the bifurcation of Madhya Pradesh in 2000, Rajasthan has been India's largest state by area.
  • That large area makes physiographic contrast unavoidable.

Physiographic Contrasts by District

Districts Physiographic association
Jaisalmer and Barmer Arid dunes and salt depressions.
Sirohi and Udaipur The high south-western Aravalli.
Jaipur, Dausa and Bharatpur Closer to the eastern alluvial plain.
Kota, Bundi, Baran and Jhalawar Tied to the south-eastern plateau and river trough.

Why Coordinates Matter

  • Coordinates matter because they place every later fact.
  • A question about rainfall, soil, drainage, border districts or crop belts is usually testing this base map.
  • The state is not wide only on paper:
    • Longitudinal spread helps explain the difference between the canal-fed north-west and the Chambal-Banas east.
    • Latitudinal spread helps explain why Banswara-Dungarpur feel different from Ganganagar-Hanumangarh.
  • The area figure also controls comparison with other states.
  • Rajasthan is larger than Maharashtra, Madhya Pradesh and Uttar Pradesh by area, but its population distribution is far less even because aridity, relief and water access break the state into contrasting belts.
  • A candidate who knows only the area number still misses why the same state contains the Thar Desert, the Abu-Sirohi highland, the Banas plain and the Chambal ravine belt.
  • In this topic, extent is not a decorative opening fact; it is the grid on which every later landform, river, border and district placement sits.

PREDICTED Predicted RAS Questions

Based on PYQ trends and 2026 syllabus analysis

1 MCQ Which pair correctly fixes Rajasthan's official locational frame?
  1. A 23°03'-30°12' N and 69°29'-78°17' E Correct answer
  2. B 20°53'-26°57' N and 67°52'-75°19' E
  3. C 26°00'-32°00' N and 72°00'-80°00' E
  4. D 22°28'-75°40' N and 960 km length

Explanation

Option A matches the state location given in official Rajasthan material. Option B belongs to the west-flowing Kutch-Saurashtra-Luni basin extent, not the whole state. Option C is a fabricated broad northern rectangle. Option D mixes Chambal coordinates and river length, so it cannot describe Rajasthan's extent.
