Let’s talk about Chilchuck’s height
The average male half-foot is 100cm/1m tall (3’3”)
Chilchuck is 110cm tall (3’7”)
This makes him 10% taller than the average.
In-universe, the average male tallman is 180cm tall (5’10”)
10% of 180cm is 18cm, 180 + 18 = 198cm (almost 6’6”)
So in universe, Chilchuck would be almost 2m tall as a tall-man
Irl, the worldwide average for adult men is 171cm (5’7.5”) - but this varies a lot from country to country
Based on this average, Chilchuck would be 188cm (6’2”)
But a lot of people are used to averages based on specific countries, so for the fun of it I’ll do one based on the average for the UK (cuz I live there), which is 176cm, rounded (5’9”)
Based on this, Chilchuck would be 193.6cm (6’4”)
I think what all of this shows is that he’s really fucking tall (for his race)
Since half-foots are often surrounded by taller races, and a half-foot marrying a dwarf doesn’t seem to be too unusual an idea, it might be that this is less of a big deal in their society since they’re used to being so much shorter than others, but Chilchuck would still be ridiculously tall.
It makes a lot of sense that he’d have to be malnourished in order to not set off traps like most of his race can do at a healthy weight.
