India Geography: Land Area, Coordinates & Dimensions

India occupies 3,287,263 square kilometers between latitudes 8°4'N and 37°6'N and longitudes 68°7'E and 97°25'E. The nation extends 3,214 kilometers north to south and 2,933 kilometers east to west. Land borders total 15,106 kilometers shared with Pakistan to the west, Tibet and Nepal to the north, Bhutan to the northeast, and Bangladesh and Myanmar to the east. Coastline measures 7,516 kilometers including the mainland and island territories. The Tropic of Cancer at 23°30'N crosses through eight states dividing tropical and subtropical climate zones.

The northern boundary follows the Himalayas for approximately 2,500 kilometers. Kanchenjunga rises to 8,586 meters on the Sikkim-Nepal border representing India's highest point. The Karakoram Range extends into Ladakh where peaks exceed 7,000 meters including Saltoro Kangri at 7,742 meters. The Himalayas formed from the collision of the Indian and Eurasian tectonic plates beginning roughly 50 million years ago and continuing at approximately 5 centimeters per year. Glaciers in these ranges number over 9,000 covering around 40,000 square kilometers. The Gangotri Glacier measures 30 kilometers in length and feeds the Ganges River. The Siachen Glacier in the eastern Karakoram extends 76 kilometers making it the longest glacier in the Karakoram and second longest in non-polar regions.

The Indo-Gangetic Plain stretches 2,400 kilometers from the Indus River system in the west to the Brahmaputra delta in the east covering approximately 700,000 square kilometers. Average elevation remains below 300 meters. Alluvial deposits measure up to 3,000 meters deep in some sections representing sediment accumulation over millions of years. The Ganges River travels 2,525 kilometers from the Gangotri Glacier to the Bay of Bengal. The Yamuna River spans 1,376 kilometers as the Ganges' longest tributary. The Brahmaputra flows 916 kilometers within India after entering from Tibet carrying average discharge of 19,800 cubic meters per second during monsoon months. The Ganges-Brahmaputra-Meghna delta covers approximately 105,000 square kilometers across India and Bangladesh representing the world's largest river delta. The Sundarbans portion within India encompasses roughly 9,630 square kilometers of mangrove forest and tidal waterways.

The Deccan Plateau occupies most of peninsular India covering approximately 1.9 million square kilometers at average elevations between 300 and 900 meters. Volcanic basalt from Cretaceous-period eruptions forms the underlying geology across much of the northwestern plateau. The plateau slopes gently eastward. The Western Ghats form the plateau's western edge running 1,600 kilometers parallel to the Arabian Sea coast at distances between 30 and 50 kilometers inland. These mountains average 1,200 meters elevation with 39 peaks exceeding 2,000 meters. Anamudi in Kerala reaches 2,695 meters as the highest point in the Western Ghats and the highest peak in India outside the Himalayas. The Eastern Ghats extend discontinuously for about 1,750 kilometers along the eastern edge of the plateau at average elevations of 600 meters. The Nilgiri Hills occupy the junction where the Western Ghats meet the Eastern Ghats with elevations reaching 2,637 meters at Doddabetta.

Rivers draining the Deccan Plateau flow predominantly eastward into the Bay of Bengal. The Godavari travels 1,465 kilometers as the second longest river in India after the Ganges. The Krishna River measures 1,400 kilometers. The Kaveri flows 800 kilometers across Karnataka and Tamil Nadu. The Narmada and Tapti rivers represent exceptions flowing westward into the Arabian Sea. The Narmada covers 1,312 kilometers through a rift valley between the Vindhya and Satpura ranges.

The Thar Desert occupies approximately 200,000 square kilometers in northwestern India across Rajasthan and parts of Gujarat, Punjab, and Haryana. Annual rainfall averages below 150 millimeters in the driest sections. Sand dunes cover about 60 percent of the desert area with some dunes reaching heights of 150 meters. The Aravalli Range runs 692 kilometers from northeast to southwest through Rajasthan with peaks reaching 1,722 meters at Guru Shikhar near Mount Abu. The Aravallis represent one of the world's oldest mountain ranges with formation dating to the Proterozoic era approximately 1.8 billion years ago.

Coastal plains border the Arabian Sea on the west and the Bay of Bengal on the east. The western coastal plain extends approximately 1,500 kilometers from Gujarat to Kerala varying in width from 10 to 80 kilometers. The Konkan coast runs 720 kilometers from Daman to Goa. The Malabar coast continues 580 kilometers southward through Kerala. The eastern coastal plain stretches roughly 1,675 kilometers from West Bengal to Tamil Nadu with widths between 80 and 120 kilometers. Major river deltas including the Mahanadi, Godavari, Krishna, and Kaveri interrupt the eastern plain.

Island territories include the Andaman and Nicobar Islands in the Bay of Bengal and the Lakshadweep Islands in the Arabian Sea. The Andaman and Nicobar archipelago comprises 572 islands covering 8,249 square kilometers located between 6°N and 14°N latitude and 800 to 1,300 kilometers from the mainland. Only 38 islands maintain permanent settlements. The highest point reaches 732 meters on North Andaman at Saddle Peak. These islands sit on the boundary between the Indian and Burmese tectonic plates. Lakshadweep consists of 36 coral islands covering 32 square kilometers located 200 to 440 kilometers off the Kerala coast. Only 10 islands support human habitation. No point on these islands rises above 5 meters.

The monsoon system drives rainfall patterns across most of India. The southwest monsoon typically arrives at the Kerala coast in early June and advances northward covering the entire country by mid-July. This accounts for 70 to 90 percent of annual precipitation in most regions. The Western Ghats force orographic rainfall with stations like Agumbe in Karnataka recording over 7,000 millimeters annually. Mawsynram in Meghalaya receives average annual rainfall of 11,872 millimeters making it among the wettest places on Earth. The northeast monsoon affects Tamil Nadu and coastal Andhra Pradesh from October to December. The Thar Desert and rain shadow areas east of the Western Ghats receive less than 500 millimeters annually.

Temperature variations span from below freezing in high-altitude areas to above 50°C in desert regions. Dras in Ladakh regularly records winter temperatures below minus 20°C. Phalodi in Rajasthan reached 51°C in May 2016. The Indo-Gangetic Plain experiences temperatures above 40°C during pre-monsoon months of May and June. Coastal areas maintain more moderate ranges due to maritime influence.

India contains portions of four biodiversity hotspots designated by Conservation International. The Western Ghats and Sri Lanka hotspot contains over 5,000 flowering plant species with 3,049 endemic to the region. The Himalayas hotspot extends across the northern mountain ranges. The Indo-Burma hotspot includes northeastern India. The Sundaland hotspot reaches the Nicobar Islands. These four hotspots combined represent about 5 percent of India's land area but contain a disproportionate concentration of endemic species.

Forest cover as measured by the Forest Survey of India 2021 assessment totals 713,789 square kilometers representing 21.71 percent of geographic area. Dense forest constitutes 99,278 square kilometers, moderately dense forest covers 308,318 square kilometers, and open forest accounts for 306,193 square kilometers. The northeast states maintain the highest forest cover percentages. The Sundarbans mangrove forest spans approximately 4,200 square kilometers within India supporting Bengal tiger populations in tidal swamp conditions. Tropical rainforests dominate the Western Ghats and northeastern regions. Deciduous sal and teak forests occur across central India. Coniferous forests appear at Himalayan elevations between 1,500 and 3,000 meters. Alpine vegetation exists above 3,500 meters transitioning to permanent snow above 5,000 meters.

Soil types vary by region and geology. Alluvial soils deposited by rivers cover the Indo-Gangetic Plain and coastal deltas supporting intensive agriculture. Black regur soils derived from basalt occur across the Deccan Plateau particularly in Maharashtra, Madhya Pradesh, and Gujarat. Red and yellow soils weathered from ancient crystalline rocks predominate in parts of the peninsula. Laterite soils formed under high rainfall and temperature conditions appear along the Western Ghats. Desert soils characterize the Thar region. Mountain soils in the Himalayas vary with altitude and vegetation.

The Indian landmass sits on the Indian Plate which moves northward at approximately 5 centimeters per year. Seismic zones divide the country into five categories based on earthquake risk. Zone V covers the highest risk areas including the Himalayas, Kashmir, the northeastern states, and parts of Gujarat. The 2001 Bhuj earthquake measured 7.7 magnitude. Zone IV includes the Indo-Gangetic Plain and some areas around the Western Ghats. Historical records document destructive earthquakes throughout the northern regions.

Water resources face demand pressure in multiple regions. Groundwater extraction rates exceed recharge rates in Punjab, Haryana, Rajasthan, and parts of Gujarat and Tamil Nadu according to Central Ground Water Board assessments. The Indus Water Treaty signed in 1960 allocates water from the Indus River system between India and Pakistan. The Brahmaputra carries enormous discharge but remains underutilized due to topographic and geopolitical factors. Interstate water disputes continue regarding sharing arrangements for the Kaveri, Krishna, Godavari, Ravi, and Beas rivers.

Mineral resources include coal deposits concentrated in Jharkhand, Odisha, Chhattisgarh, and West Bengal totaling proven reserves above 140 billion tons as of Geological Survey of India assessments. Iron ore reserves exceed 30 billion tons located primarily in Karnataka, Odisha, Chhattisgarh, and Goa. Bauxite deposits occur in Odisha, Andhra Pradesh, and Gujarat. India holds thorium reserves exceeding 800,000 tons ranking among the highest globally with deposits in Kerala, Tamil Nadu, and Odisha monazite sands. Copper, zinc, lead, gold, and diamond deposits exist in smaller quantities across various states.
