The article is careful to say “most extreme” wave, not biggest. They’re defining that as the wave’s height in comparison to the other waves around it.
"Scientists define a rogue wave as any wave more than twice the height of the waves surrounding it. The Draupner wave, for instance, was 25.6 meters tall, while its neighbors were only 12 meters tall.
In comparison, the Ucluelet wave was nearly three times the size of its peers.
“Proportionally, the Ucluelet wave is likely the most extreme rogue wave ever recorded,” physicist Johannes Gemmrich from the University of Victoria in 2022."
