Provinces of Thailand, matched to countries
Natural Earth’s file divides Thailand into 77 provinces. Below, each is drawn at true scale and matched to the country closest to it in area and in population.
Bangkok is a special administrative area, not a province, and is counted among the 77. Natural Earth’s file labels all 77 as provinces.
Population: the 2020 figures Wikidata holds, for 76 of the 77 provinces. The only figure it has for Bangkok (2018) is a different year, and it is shown with that year. Every population on these pages carries its year; they are not one count taken on one day.
At a glance
- Chiang Mai, the largest, is 54.9× the size of Samut Songkhram, the smallest.
- The five largest, Chiang Mai, Nakhon Ratchasima, Kanchanaburi, Tak, Ubon Ratchathani, cover 18% of Thailand.
- None of the 77 is larger than the United Kingdom (244,000 km²).
- None of the 77 is larger than France (548,000 km²).
- Bangkok, the most crowded, has 3,630 people per km²: 173× Mae Hong Son, the least crowded (21).
- Half of the people counted live in the 20 most populous (Bangkok, Nakhon Ratchasima, Ubon Ratchathani, Khon Kaen and 16 more), which cover 37% of the area; the years of the figures differ.
- 0 of the 77 have more people than the median of the 38 European countries listed here (6.6 million).
- 11 of the 77 are within 10% in area of a European country, among them Trat and Luxembourg (1.00×), Mae Hong Son and Montenegro (1.01×), Kanchanaburi and Slovenia (1.02×).
Every province matched to a country
Largest first. The matches are the countries closest in area and in population from Natural Earth’s country list; contested places and dependencies are never used as matches. Population is the newest figure Wikidata holds, with its year.

Too small to see on the map
At the scale of the map these units are a few pixels wide or less, so they are ringed on the map and drawn here as discs of true relative area. Each is matched to the small countries and island nations, not to the countries of 1,000 km² and more.

What the reorganisations did to the numbers
Thailand has reorganised its units. Undoing each change on today’s outlines shows what it did to the size and rank of the units. The years are from this site’s configuration; the numbers are added up from the outlines and Wikidata’s figures.
- 2011
Until 2011, the province of Nong Khai covered what is now Nong Khai and Bueng Kan.
7,430 km² added together. As one unit: 27th of 76 by area, 25th by people with 939,000 (2020), 1.01× as many as Fiji. As two: Nong Khai 59th and Bueng Kan 55th of 77.
Wikidata still holds an older area of 7,330 km² for the undivided whole: within 1.3% of the two outlines added up.
Beside the regions of other countries
Every province also has a closest match, by area and by people, among the 318 regions of the other 12 countries. All the matches, in both directions, are on one page.
