Whether Victoria Falls is "bigger" than Iguazu Falls depends entirely on which metric you use: height or width. Victoria Falls (on the border of Zambia and Zimbabwe) is significantly taller, standing at 108 meters (354 ft) compared to Iguazu’s 64–82 meters. It is also classified as the "world's largest sheet of falling water" because it is a single, continuous curtain nearly 1.7 kilometers wide. However, Iguazu Falls (on the border of Argentina and Brazil) is technically wider overall, stretching across 2.7 kilometers (1.7 miles). Iguazu is a complex system of approximately 275 individual waterfalls and islands rather than a single curtain. In terms of water volume, Iguazu generally has a higher average flow rate of about 1,746 cubic meters per second, compared to Victoria’s 1,088. In summary: Victoria is the largest single curtain and the tallest of the two, while Iguazu is the largest "system" of falls and carries more water on average throughout the year.
