They are all over the place. Some of the "hero" minis are 32-35mm scale, and some are just at 28mm. The smaller ones are more "naturally" proportioned. And the larger ones more "heroic". So bring a figure with you to check scale. The D&D goblins are tiny, the orcs are huge, the gnolls tower over the northstar gnolls, but the bugbears are about the right size. The Pathfinder goblins look about right, but are twice the size of Paizo's pre-painted Pathfinder goblins, in fact their heads are the size of the pre-paints alone! Not a problem if you don't have any of the pre-paints, which are tiny. I did pick up 4 packs of them, and I have about 80 of the prepaints.
