Baffling anyone can look at that and see 8.25”. The tape has slack, yes, and the measurement isn’t perfect by any means. But it reaches about 24.25 cm with the incorrrect measurement. No on is saying he’s 9.5” with a correct measurement.
It seems like a pretty fair starting point, he’s standing, and it’s parallel to the ground, so if you straightened out the slack, and took a looking straight down shot, I fail to see how he loses any more than a cm or so. So 23-23.25 cm IMO. (9.055 - 9.154 inches).
Just because what the hell, let’s take off the extra little 0.25 cm and just say 23.
