Amsterdam vs Rotterdam: which is bigger by population and area? (2026)

Amsterdam is bigger than Rotterdam by population, but Rotterdam is bigger by physical area. On 1 January 2026, Amsterdam had about 941,900 residents compared with about 673,800 in Rotterdam. Rotterdam, however, covers roughly 324 km² of municipal territory, compared with about 244 km² for Amsterdam.

So the answer to “which city is bigger?” depends entirely on what you are measuring.

Amsterdam vs Rotterdam at a glance

----------------------

Which city has more people?

Amsterdam is clearly the larger city by population. Statistics Netherlands, or CBS, counted approximately 941,900 residents in Amsterdam and 673,800 in Rotterdam on 1 January 2026.

That means Amsterdam has roughly 268,000 more residents than Rotterdam. It remains the largest municipality in the Netherlands by population, with Rotterdam in second place.

The difference is striking because Amsterdam fits those additional residents into a smaller land area. The latest CBS density figures put Amsterdam at 4,968 residents per square kilometre of land, compared with 3,081 in Rotterdam.

Which city covers more area?

Rotterdam wins when we compare the territory inside the municipal boundaries.

Amsterdam covers approximately 244 km² in total following the incorporation of Weesp, including about 188 km² of land. Rotterdam covers about 324 km² in total, with roughly 218 km² of land.

Rotterdam therefore has around 80 km² more total municipal territory than Amsterdam and about 30 km² more land.

This distinction matters because a municipality's total surface area includes water as well as land. Both cities contain substantial waterways, but Rotterdam's territory includes especially large stretches of river, harbour and coastal water.

Why is Rotterdam so large?

Rotterdam's size is closely connected with its port and the way its municipal boundary stretches westwards from the city centre towards the North Sea.

The municipality encompasses extensive docks, industrial zones and waterways as well as places farther from the central city, including Rozenburg and Hoek van Holland. Rotterdam's own spatial planning documents describe a municipality of around 320 km², about one-third of which is water.

The port itself is enormous. The Port of Rotterdam remains Europe's largest port, and its port and industrial area covers about 12,500 hectares of land and water.

Rotterdam's post-war reconstruction also helps explain why the central city often feels more spacious than Amsterdam. After much of the centre was destroyed in the Second World War, Rotterdam developed around broader roads, modern architecture and a different urban layout from Amsterdam's historic canal centre.

What about metropolitan areas?

Metropolitan population figures require more caution. There is no single boundary that everyone uses for the “Amsterdam metropolitan area” or “Rotterdam metropolitan area”. Different statistics may refer to urban areas, commuting regions, transport authorities or wider administrative partnerships.

Those definitions are not interchangeable. For example, official regional statistics can group Rotterdam with The Hague and surrounding municipalities, making that figure unsuitable for a simple city-to-city comparison with Amsterdam.

For that reason, municipal population and municipal area offer the clearest like-for-like answer to the question.

So, which city is bigger?

Amsterdam is bigger by population. Rotterdam is bigger by area.

If by “bigger city” you mean the number of people living within the municipality, Amsterdam wins comfortably, with about 941,900 residents compared with Rotterdam's 673,800.

If you mean the amount of territory inside the municipal boundary, Rotterdam is larger, at about 324 km² compared with Amsterdam's 244 km².

The figures also help explain why the cities feel so different. Amsterdam packs substantially more people into a smaller area, while Rotterdam spreads across a much larger territory shaped by the Nieuwe Maas, Europe's largest port and the route towards the North Sea.
