From the FL Website for those who may have missed it , seems pretty upfront to me . Regards Gebhard
"There are many figures scales out there for both Toy Soldiers and Historical miniature wargames figures and even different classifications within the same scale. Thus, we want to provide you with this simple guide to the scale of our figures. All of our painted figure ranges are 60mm or true 1/30th in scale. Please note that we have changed our descriptions from 54mm to 60mm simply because it more accurately describes the actual size of the figures. We have not changed the size of the figures, only the classifications! If this doesn't fully answer your questions regarding scale, please don't hesitate to contact us.
We are quite often asked about the relative size of our figure ranges as compared to one another. To assist you with this we've take a figure from a few of our ranges and photographed them next to one another. As you can see, most everything is pretty close in size with perhaps the Crusaders being a tiny bit bigger and the WWII being a tiny bit smaller. But generally speaking, the goals of the scales are to be true 1/30th or 60mm but as with any artistic endeavor such as this, some slight variance may exist from sculptor to sculptor!"
