::I also believe Goku's height is about 170cm(5'7") as the Daizenshuu says. However, I found an interesting material saying his height is 175cm. I wouldn't think highly of this if this claim is on a private site, but this fact that Goku's height is 175cm is on a Japanese wikipedia page. Because Japan is where Dragonball series were born, I carefully propose that Goku's height could actually be 175cm as the Japanese wikipeia page says. If his height is really 5'7" as the Daizenshuu states, someone must prove that 5'7" is height of not 'growing' Goku, but 'fully-grown' Goku, and the content on the Japanese wikipedia page that Goku's height is 175cm must be retorted. Here's the site that insists Goku's height is 175cm.  You have to click "3 性格など" in the list to see this site's claim.
