As requested, a comparison of Wiglaf Miniatures 18mm Saxons (3 models right) with 15mm Forged in Battle (3 models left from packs WL4 Welsh Spearmen and GX5 Saxon raiders). As you can see, the ‘15mm’ and ‘18mm’ labels are pretty irrelevant. Both ranges stand around 20mm tall and are largely compatible. Wiglaf are slightly more 3-dimensional due to the poses and the separate spears, meaning they take up slightly more space on the base, but frankly the differences are marginal. This isn’t a ‘new scale’, it’s an already existing scale sculpted by one of the best.
