Something i have wondered for a while.
I was thinking Nords are around 5'10-6'5''
I was thinking about imperials and bretons are on the order of 5' 5'' to 5'9''

I could not find it mentioned anywhere in the lore but tall and fair skinned. I suppose we can imagine what we want them to be.
What do you guys think?

probably in the 6 ft range, with the other human races being in the upper five foot. I'd say altmer would be close to six and a half feet maybe

I'd say nords are around 6'2" in game in skyrim.
Imperials maybe 5'9" or 5'10"
And those darned ugly, snooty, skinny high elves about 6'10.
