To put that in perspective, Iguazu Falls is nearly twice as tall as Niagara Falls and rivaled only by Zambia and Zimbabwe's Victoria Falls, which is taller at 108 meters. It's nearly three times as wide as Niagara Falls and significantly wider still than Victoria Falls.

Iguazu Falls, located on the border of Argentina and Brazil, is significantly larger than Niagara Falls in almost every physical dimension except for sheer water volume per second. Iguazu is approximately 2.7 kilometers (1.7 miles) wide, making it more than twice as wide as the 1.1-kilometer-wide Niagara. While Niagara consists of only three distinct drops, Iguazu is a massive system comprised of about 275 individual waterfalls and cataracts spread across a horseshoe-shaped canyon. In terms of height, Iguazu’s tallest drop (the "Devil’s Throat") reaches roughly 82 meters (269 feet), whereas Niagara’s tallest drop, the Horseshoe Falls, is about 51 meters (167 feet). However, Niagara is more "powerful" in one sense: it has a higher average flow rate (roughly 2,400 cubic meters per second) compared to Iguazu’s 1,750 cubic meters per second. This is because Niagara’s water comes from the massive Great Lakes system, while Iguazu relies on the Iguazu River. In summary, if you want "wide and wild," Iguazu is the winner; if you want "focused power," Niagara takes the crown.
