Have you ever scrolled through a map and wondered: Which is the largest city in the world by area? You’re not alone. Many travel enthusiasts, students, and even trivia lovers find themselves curious about the scale of cities we hear about every day. We often think of bustling megacities like New York, Tokyo, or Manila, but size isn’t just about population—it’s about land area too.
If you’re someone who loves discovering fascinating world facts, enjoys travel conversations, or just wants to impress friends with geography knowledge, this post is written for you. Let’s take a closer look at which city claims the title of “largest in the world by area,” why it matters, and some surprising insights you may not expect.
What Does “Largest City by Area” Really Mean?
Before we jump into the rankings, let’s clear up the confusion. “Largest city” can be defined in two ways:
-
By population: How many people live there.
-
By land area: How much space the city covers.
In this blog, we’re focusing on land area—the total size of the city’s administrative boundaries.
The Largest City in the World by Area
The city that takes the crown is New York City, USA, with an area of approximately 12,093 km² when measured as the metropolitan region. However, depending on how “city limits” are defined, some rankings consider Hulunbuir, Inner Mongolia, China, which spans a jaw-dropping 263,953 km²—almost the size of the entire United Kingdom!
So, why the difference? It comes down to how we define a “city”:
-
Administrative boundaries (official city limits).
-
Urban sprawl or metropolitan region (the city plus its suburbs and surrounding towns).
For trivia buffs:
-
Largest city proper by area: Hulunbuir, China.
-
Largest metropolitan city by area: New York, USA.
Surprising Comparisons That Put It Into Perspective
Sometimes numbers alone don’t sink in. Let’s compare:
-
Hulunbuir, China (263,953 km²) is bigger than the entire country of New Zealand.
-
New York Metro (12,093 km²) is larger than Jamaica or Lebanon.
-
Tokyo, often thought to be the largest city, actually leads in population, not land size.
Pretty mind-blowing, right?
Why Does City Size Matter?
You might wonder: Why should I care how big a city is by area? Well, here’s why it’s fascinating:
-
Urban Planning & Travel: Larger cities face unique challenges—transportation, housing, and environmental management.
-
Lifestyle Differences: Living in a city spread over hundreds of thousands of square kilometers feels very different than in a compact city.
-
Fun Trivia Knowledge: Next time someone says “Tokyo is the biggest city,” you can surprise them with the correct answer!

If you’re a student, this is a great example of how definitions can change facts. If you’re a traveler, it might inspire you to explore less-talked-about destinations like Hulunbuir, which boasts stunning grasslands, lakes, and rich Mongolian culture.
And if you’re simply a curious learner, these city comparisons can become your go-to “did you know?” fact at social gatherings.
Conclusion: So, Which City is the Largest by Area?
