If you look at the triumph of Ulanor picture, where theres 9? Primarchs all present at the same time, they do vary in height, but not as severely as one towering(3+ feet) over the others.

I've personally always seen unarmored Astartes as 7-8 feet, depending on physical differences. Haegr of the Wolfblade was massive compared to other full Space Wolves. I have trouble seeing the armor they wear giving another foot to their height (those boots have to be all heel otherwise).

Armored Astartes stood in my mind at about 8-8.5 feet depending on physical differences in their unarmored bodies.

Primarchs ranged in size, the tallest standing at over 12 feet tall, and the smallest at about 9.5, even amongst Space Marines the Primarchs were still taller then the Astartes.

Emperor I always saw as being about 10.5 feet tall. This being because some of the Primarchs were physically gigantic. I also used this in reference to the Emperor on Horus' ship because if you compare the relative size, Horus looks to be slightly taller, and Sanguinius looks to be shorter then the Emperor.

This is all how I percieved them in my readings of the books though. Don't bother to tell me how wrong I am, I won't care.
