Who was bigger Inca or Aztec?

The Inca Empire was larger in terms of land area compared to the Aztec Empire, stretching across much of western South America, including parts of modern-day Peru, Ecuador, and Chile. In contrast, the Aztec Empire was primarily located in central Mexico. However, the Aztecs had a larger population density in their core region, particularly in their capital, Tenochtitlán. Both empires were significant in their respective regions, but the Incas had a more extensive territorial reach.
