Size of Warhammer figures? Not scale, SIZE

Okay I’ve been thinking about painting a couple warhammer 40k figures since those space marines are oh-so-cool. Anyways, I’ve heard they are 28mm or roughly 1/60 scale. But heres the question. For example, the 28mm refers to how tall a standard 5’11-6’ or so man would be in that scale. So A figure of an imperial guard or something would be just that, around 28mm. But a steroid filled, genetically modifed beast of a man in extremely big power armor (A space marine) Would proabably be a good amount bigger. Not to mention that figures are always bigger than said. For example 54mm models always seem to measure in the 60mm range. So how tall is a space marine in terms of mm? How would it look next to a 1/35 figure? I know it would be smaller but I build 1/35 so that would be the best reference to me. Thanks!

actually they look closer to my 1/48 figures as far as height goes, just slightly buffer in physical build. but yea they fit into the 28mm mini category. i will snap a pic for u asap.

Thanks!, thats just what I was looking for.
