[2021] Do we have any kind of exact measurements for the dwarves and the beings around them?

I've been thinking about it a lot recently while mining, the average glyphid grunt is about half the size of the dwarves and the praetorian is roughly 1.5 - 2 times the size. If these are the cases how tall are these bugs compared to humans and elfs? What about goblins? How tall is a Dreadnought compared to one of those tiny little dudes? And in that mindset how big would the caves be to the taller races and how much more difficult would it be for them to traverse?
