Thailand is a country in Southeast Asia. Formerly known as Siam, Thailand is now known as the Kingdom of Thailand. Thailand is located between China in the north and India in the west, as part of the Indochinese Peninsula.

Most Extreme Points and GPS Coordinates

Thailand is located north of the equator, as indicated by its GPS coordinates. Thailand is surrounded by four Asian countries at a latitude of 15.8700° N and a longitude of 100.9925° E. Myanmar lies to the northwest, Laos to the north and northeast, and Cambodia to the east and southeast. Thailand is located south of Malaysia. Check out more details here on

Total Area and Population Size

The area of Thailand is 198,120 square miles, making it the 50th largest country in the world. It is almost entirely made up of land regions in Thailand. There is only 0.04% water in the country, leaving 99.6% as land. Thailand’s land area totals approximately 197,327.52 square miles, with a little over 790 square miles of water in the form of lakes and rivers.

Thailand has a population of about 69,251,318 people as of 2018. With an annual growth rate of 0.21%, Thailand is the 20th largest country in terms of population size.

There are approximately 349.54 people per square mile in Thailand, which is calculated by dividing the population by the total area. In terms of population density, Thailand ranks 88th.

##Highest, Average, and Lowest Levels of Elevation

The average elevation of the land in Thailand is 942 feet above sea level. Thailand reaches an altitude of 8,415 feet above sea level at its highest point. Doi Inthanon Mountain is located in one of Thailand’s most famous districts, the Chom Thong District. As Thailand is at sea level with the Gulf of Thailand, the lowest point is 0 feet above sea level.

Land of Thailand

There are two broad geographic areas in Thailand: a main section in the north and a peninsular extension in the south, which has about the same land area as Spain or France. Myanmar (Burma) surrounds the main body of the country west, Laos to the north and east, Cambodia to the southeast, and the Gulf of Thailand to the south. From the southwestern tip of Thailand, Peninsular Thailand extends along the eastern edge of the Malay Peninsula; Myanmar occupies the western portion of the peninsula until the Isthmus of Kra, after which Thailand occupies the entire peninsula until reaching Malaysia at roughly latitude 6°N.


Thai landscapes range from low mountains to fertile alluvial plains dotted with rice paddies to sandy beaches set amid the equatorial latitudes of the Asian monsoon. The country is divided into five distinct physiographic regions: the folded mountains in the north and west, the Khorat Plateau in the northeast, the Chao Phraya River basin in the center, the maritime corner of the central region in the southeast, and the long, slender peninsular portion in the southwest.

Located along the Thai-Myanmar border and reaching as far south as northern Malaysia, the northern mountains are the southeastern continuation of the uplift process that formed the Himalayas. Molten rock forced its way upward through sedimentary strata to form long granitic ridges. Peaks average 5,200 feet (1,600 metres) above sea level. At 8,481 feet (2,585 metres), Mount Inthanon is the highest point in Thailand, near the historical city of Chiang Mai. Overshadowing the city is Mount Suthep, the site of a famous Buddhist shrine and the royal summer palace. The rugged limestone hills contain caves where prehistoric human remains have been discovered.

A vast tableland bounded on the north and east by the Mekong River, the northeast is coterminous with the Khorat Plateau. In the west, it was formed by uplifting along a north-south trending crustal fault, while in the south, it was formed by uplifting along an east-west trending crustal fault. Thus, sedimentary rocks underlying the sediments were tilted rather than uniformly uplifted. There are low hills and mountains along the western and southern edges of the plateau: the Phetchabun and Dangrek (Thai: Dong Rak) mountains. These uplands overlook the plains of the Chao Phraya basin to the west and the Cambodian plain to the south. Khorat Plateau elevations range from about 650 feet (200 metres) in the northwest to some 300 feet (90 metres) in the southeast. The terrain is rolling, and the hilltops slope southeast in accordance with the tilt of the land.
