Copplestone are fairly big too. I was a bit disappointed that the orcs looked like GW orcs (black orcs, even) beside my BoFA elves. But tomayto tomahto.
Yes, by GW I was meaning the Warmaster figures - not the BoFA ones. The BoFA plastics are very slight in build and a bit shorter than most 10mm.
You definitely have a range of sizes with 10mm
BoFA < WM, Copplestone, Magister Militum, Pendraken Historical, Eureka < Kallistra, Pendraken Fantasy.
I use all of them on the same table though
