yeah but if we talking about giants then I'd say height is what determines it right?

i used length because if you go by height blue whales are definitely not enough to be considered giants (one blue whale should be what? 5 humans standing up) specially if you compare the height of a human and an insect

that is the weight, a blue whale is the length of 15 grown men lying down

but whales are only times bigger than humans, while humans are 1000x or so bigger than insects
