Yeah, Kaido actually stood next to Jack on the performing stage one time, he's significantly shorter than Jack.
Kaido is close to Moria's height, which makes sense, but a good amount shorter than BM, which is a bit odd, since BM and Kaido look pretty close in height most of the time.
1.39 is pretty stupid, but at least it's not that 1.33 shit and Ndule was right saying Luffy has the highest non Yonko bounty, therefore capping all the YC below 1.5. Only Beckman might go in the 1.4xxx.
Kaido being 59 is interesting. It kinda puts him in between the old gen (WB, Roger, Meme) and the current gen though closer to the former.
Guess in that case they were talking about "standing" in the crew? It's clear the even though KQJ have the same rank KQ boss Jack around, and at the end of the day K calls the shot over Q when necessary as well. We've seen this during the raid tbh.
