- While the Yarlung Tsangpo is over 504 km long, the Grand Canyon is roughly 277 miles (446 km) long, making the latter more extensive.
- The Grand Canyon is also deeper, with a maximum depth of 6,000 feet (1,800 meters), compared to the Yarlung Tsangpo Canyon's maximum depth of 2,000 meters.
- The Grand Canyon has an average width of 18 miles (29 km) and a maximum width of 21.5 miles (34.6 km), while the Yarlung Tsangpo Canyon has an average width of 1 mile (1.6 km) and a maximum width of 2 miles (3.2 km).
So, while the Yarlung Tsangpo Canyon may be longer, the Grand Canyon is both deeper and wider, making it the larger canyon overall.
