The Space Marines are the poster boys of this because, if you find some classic Space Marines (from 3rd Edition or so) then they’ll be very close to 25mm. Generally speaking, we can consider Warhammer 40k to be 32mm heroic scale, and the debate between 28mm vs 32 mm miniatures is really something of the past, as Warhammer models used to be much smaller and have grown consistently in size (with no end in sight).


It really only comes into play when you’re talking about Imperial Guard (regular humans) but even there a 28mm Imperial Guard model would look very out of place standing in a unit of 28mm Warlord WW2 miniatures. Space Marines are seven feet tall (without power armor) and Primaris Marines are even taller than that. Technically, Warhammer models range somewhere between 28mm and 32mm, but in practice that means very little.
