Countries by GDP: The Full Ranking
By The WorthMore Team · Updated June 5, 2026
Which country has the biggest economy — and by how much? Here are the world's largest economies by nominal GDP, plus a game to test how well you really know them.
Quick answer: the United States has the world's largest economy at about $29 trillion, followed by China at roughly $18 trillion. No other country comes close — third-place Germany is under $5 trillion. Below is the ranking of the biggest economies by nominal GDP (approximate, 2024 figures).
Top 15 countries by GDP
| # | Country | Nominal GDP |
|---|---|---|
| 1 | United States | $29.2 trillion |
| 2 | China | $18.3 trillion |
| 3 | Germany | $4.7 trillion |
| 4 | Japan | $4.1 trillion |
| 5 | India | $3.9 trillion |
| 6 | United Kingdom | $3.6 trillion |
| 7 | France | $3.2 trillion |
| 8 | Italy | $2.4 trillion |
| 9 | Brazil | $2.3 trillion |
| 10 | Canada | $2.2 trillion |
| 11 | Russia | $2.2 trillion |
| 12 | South Korea | $1.9 trillion |
| 13 | Mexico | $1.9 trillion |
| 14 | Australia | $1.8 trillion |
| 15 | Spain | $1.7 trillion |
Figures are approximate nominal GDP for 2024, rounded, from public sources such as the IMF and World Bank. Rankings shift slightly year to year.
Nominal GDP vs GDP per capita
This list ranks total output (nominal GDP), which rewards large populations — that is why India and Brazil rank highly despite lower average incomes. A very different list appears when you divide GDP by population to get GDP per capita: small, wealthy nations like Luxembourg, Ireland and Switzerland jump to the top, while giants like China and India fall far down. Both are "correct" — they just answer different questions: total economic size versus income per person.
The US vs China gap
The two largest economies are in a league of their own. Together the US and China account for roughly 40% of global GDP. The gap between them has narrowed over two decades but remains large in nominal terms — partly because GDP measured in US dollars is sensitive to exchange rates. Measured by purchasing power parity (PPP), which adjusts for local prices, China's economy is often ranked as the world's largest, which is why you'll sometimes see conflicting headlines.
