It's because Toriyama gave their heights in feet and inches despite clearly not understanding those measurements.

The official heights for the DB characters are absolute bullshit and seriously off.
Bulma, Chichi and Videl are presumably of average or close to average height, this is supported by the fact that most women in the DB world seem to hover around that height.
Goku and Gohan are both at least two heads taller than any of them, possibly three. Goku and Gohan are both freaking huge, Piccolo's even taller, Raditz is even bigger than him, and there's no way in hell Nappa isn't at least two and a half, possibly three meters tall.
Vegeta, considered a midget by Saiyan standards, is about on par with an average Earth woman.

When viewed at the proper size, they're good. Also they're Viz' translation. Well, part of that is Boo arc art being a bit sloppy.
I'm planning to use them in my blog if I can revive it.

Oh. I thought it was the horrid fan scanlation that looks like crap and is rather poorly translated.
Let the joy of love give you an answer! Check out my book!To be fair, 18's getting off for Blackmail.
I love you, Krillin!! -struggling to breathe- I love you as well, honey..You mean 18 is a pretty girl.
Though yeah, the lack of perversion does make her look better.
Plus she blackmailed Satan. He kinda deserves it.
Also, still binging on Super to catch up. Just did episode 15.....
Satan defeats God. You heard it hear first.
You know, I alternate between finding Mr. Satan hilarious, and wanting to kick his ass
One Strip! One Strip!

Krillin's official height is 5 feet tall. By the way, Vegeta's official height is 5'4.5", Goku's is 5'9", and Piccolo's official height is 7'5".
Edit: edited to be right.
