But that's not nearly what we're talking about. 180cm is easily within human limits. Is it abnormally tall? For Korea, yes, it is abnormally tall. For modern Korean women, it's somewhere on the order of ~0.2%, assuming a normal distribution. But also in modern Korea, that equates to over 50,000 women. Do these women simply cease existing because they're a few standard deviations away from average? Of course not.
Let's look at some canonical Servants for comparison's sake. Blackbeard is 210cm tall. Based on UK averages of today, he's 0.0000000464% of the population. With the same reference point for population, he's 0.0312 people. He's statistically more likely to not exist even in modern Britain, let alone the Britain in which he was born. Oh, but I suppose he's British, they don't count because Camelot is a silly place, we shouldn't go there. Let's get a bit geographically closer. Kintoki is 190cm, plugging in the numbers, etc. so forth, and dear me! He represents about 0.42% of the Japanese male population! Now we're getting close to that 0.2% mark aren't we? Oh, but I do suppose he's a demigod, that's simply unfair! How about EMIYA? He's a nondivine, modern human, so it seems reasonable to me! Plug the numbers in for his 187cm height and he comes out to 0.8%.
Now be honest with me: did you ever stop and go "Oh, he's that tall? That's incredibly unrealistic, keep where you're writing in mind, authors!"? I'm beyond reasonably confident that you didn't. You didn't stop to think about how Blackbeard's inhumanly tall, or how even someone like EMIYA is very unusual in height. Disbelief was happily suspended for them.
Oh, but let's go even further! After all, they're all men, aren't they? Maybe it's just a male thing. Just boys being boys. How about we try a few female Servants on for size too. Quetzalcoatl is a rather tall woman, 181cm. Plug it in, that's 0.0091% of the Mexican population. ˇAy dios mio! That's even less likely than 180cm in Korea! Oh, but I suppose she a human infested with god bacteria. That's not a fair comparison! Maybe Zenobia, she's completely human, so surely she's a decent comparison? Well, she's 0.41% of the population of the closest modern equivalent to her region of birth, Syria (which is where Palmyra is). Twice as likely as Jini, but in the same ballpark. Is she tall? Yes! Is she inhumanly tall? Certainly not! Does she need any justification or note about her height? Of course not. Humans, shock horror, can just be born tall.
Oh and for reference, all of these probabilities are for "Height x or greater", just to be clear. Height is a continuous dataset and it's much more effective to find these numbers than to find an interval around them, especially with numbers like this (below 5%) desu yo~
