If we were talking about the real world, of course it would be silly to ask the question of whether or not a second-year junior high school girl grew taller as she got older, but we’re talking about an anime/manga where characters have all manners of hair colors and are named after rabbits, so nothing should be taken for granted. For the sake of convenience, we’re going to be restricting our discussion today to only the anime since the manga both lacks the hard numbers that we need and also tends to be a little bit more liberal in the character designs from scene to scene. But for the purposes of our discussion – namely, whether Usagi actually grew physically (though emotionally is another story!) throughout the series – we should have more than enough information to answer that.
Before we start talking about hard numbers, though, we should probably discuss our methodology and where we’re getting these stats from. While it’s hard to get numbers on exact heights for the any of the cast, we’re lucky in that Usagi’s height is given as 150cm.1 Fortunately for us, it’s not too difficult to find scans of the character design sheets used by the anime artists when animating Sailor Moon, so we can extrapolate the heights of the other characters from there.
Going with the assumption that time was reset after the fight with Beryl or, if you prefer, the theory that the Dark Kingdom Arc was actually short lived, we have every reason to believe that Usagi’s height didn’t change much, so we can keep using our 150cm figure for Sailor Moon R.
Things start to get complicated once we reach Sailor Moon S, however, since we know that Usagi has a birthday and that they’ve moved forward in school. Here, we will use Mamoru as a base for comparison and extrapolate numbers from there. Men, on average stop growing by the time they reach their early 20s,2 so it’s reasonably safe to say that his height is probably set.
I couldn’t find any other official materials that showed the characters standing reasonably straight and with mutual characters (to use as a ruler), so unfortunately I don’t have a complete data-set for Sailor Moon R, SuperS, or Stars. If anyone has any materials, I’d be more than happy to check and add to this table!
So what you can see here is that not only does Usagi actually get taller, but you can see that all of the other characters get taller as well. Even using the questionable math on Mamoru’s height being the same, you can see that Usagi rapidly caught up to Ami, with just a 6cm difference in height when it used to be over double that, at a difference of 13cm in the original.
Interestingly enough, Usagi’s height puts her actually at the low end of girls her age, with the average height of fourteen year old girls in Japan being 156.5cm.3 Her height from Sailor Moon S and beyond is right about in-line with the national averages, or even a little on the tall side. That might explain why Usagi’s hungry all the time – she was in the middle of a massive growth spurt!
So there you have it! It turns out that Usagi did indeed grow as the series progressed, as did the other Sailor Soldiers! I’m still on the lookout for more pictures that can be used to narrow down their heights, so if you know where to find other character design sheets for Sailor Moon R, SuperS, or Stars, I’d appreciate a heads up!
