Beijing covers about 16,410 square kilometers (6,335 sq mi) and is home to over 21.83 million people. Its massive scale reflects not only size, but also its national and global importance.
Geographic Size: A Capital with Vast Land
Beijing is much larger than many major world cities:
About 100 times the size of Washington, D.C.
Nearly 10 times the size of London
Includes mountains and plains: 62% of the area is hilly or mountainous (north and west), while the south and east are flat and urbanized.
The city is divided into 16 districts, ranging from the historic urban core (e.g., Dongcheng, Xicheng) to outer rural districts (e.g., Miyun, Yanqing), which include famous sites like the Great Wall and Miyun Reservoir.
Population: One of the Largest Cities in the World
As of 2024, Beijing has a permanent population of about 21.83 million.
That’s 4× Sydney and nearly 2× the Paris metro area.
Population density averages around 1,300 people/km², with extremes ranging from:
Over 25,000 people/km² in central districts
Fewer than 150 people/km² in some suburban areas
This distribution reflects Beijing’s design: dense urban core, spacious outer areas for tourism, nature, and agriculture.
Urban Structure: From Ancient City to Modern Metropolis
Historical Center:
The old city, where the Forbidden City is located, spans about 62 km² and preserves ancient palaces and hutongs.Modern Expansion:
The city now features concentric ring roads, from the 2nd to the 6th ring road (the 6th is 187 km long), encircling urban and suburban zones.Functional Zones:
Haidian District – home to top universities and tech (e.g., Tsinghua, Zhongguancun)
Chaoyang District – business and diplomatic hub (embassies, CBD)
Tongzhou District – the city’s new “sub-center” for future government and residential functions
Summary
Beijing is big in every sense:
Land area: 16,410 km²—larger than many countries’ capitals
Population: 21+ million people
Role: China’s political, cultural, and innovation center
From imperial palaces to international tech zones, from crowded avenues to peaceful mountains—Beijing’s scale and diversity truly make it a global megacity.
